A

Today we have a little bit of changes in the meetup we planned for this to be the api, that's one of the new features of stuff, but instead we decided to do stuff in linux, so that will be the topic of today.

A

This is a topic that I truly like I've been working on that thing since, uh since I knew that the staff was going to be able to handle it, so I've been doing all possible type of research on that, and here with me, is dave the express mvp dave. If you want to take the mic just to say, hi,.

B

Yep hi dave uh for llama chat technology been using xaf since it was released in 2008. uh I'm pretty excited to see this thing running on linux, so here we go.

A

Yeah, so also I am for the king, I miss nude, but in any time he wants to say, hi uh he's also welcome, uh but anyway we have like small agenda for today. um Well, this is what we will see today is like uh a lot of the research that we have been doing in the office. So that's what what I I will show in this case.

A

uh If well, I guess everyone knows me, uh but for the people who is new or who will watch this video on youtube, my name is jochio veda, I'm from el salvador. I work for sorry. I need frameworks.

A

uh I've been working on staff for like forever, basically from day one of xaf and well like uh one of my passions, is to software development and supporting pictures. So that's why I love stuff so much so uh here we want to share like all everything that we find everything that we do like as a result: research in the office. So we're really glad to share this knowledge with you guys and hope that that you will use it uh actually and that will be helpful for you so well. This is the agenda for today.

A

It's like uh first we're going to see the stuff they sort and play project. What is it all about, then? We will check how to get the template from new order and we'll have a demo in ubuntu like deploying from ubuntu to another ubuntu server. Then we will have like a small demonstration of the shortcuts.

A

uh We did all the shortcuts for for bs code, so it mimics coders and then we'll do the same demo like deployment with the script from windows to linux, but that will be using wcl, which is windows subsystem for linux. So this is like um my powerpoint. So the first thing I'm going to do before I start with the demonstrations. Is I'm going to totally clean this virtual machine, which is an one ubuntu server that I have locally? Actually, my machine is ubuntu.

A

My windows is a visual machine, so there's a lot of machines inside of other machines. So, first of all, let's go here and let's see, let's start little by little. Let me just move this here so.

A

The first part that we're going to see is the idea of the break. So basically we have. We have created uh open source project, which is a template for dot net new. So the template is based on a soft application, including a software api. You can see it here, so you can download the source uh from this uh repository.

A

Everything is open source and here you will see right now, we're in version one 1.2 and it was released yesterday because we've been testing this a lot like for a few weeks already- and we have something like this before, but um but it was not public because I personally had problems with nuvit or id. I wasn't able to sign in. I lose my account so now I have it back so just one sec.

A

um uh So if you need something, you need to add some new features, and you can just come to here and open an issue. I have not done the template for the issues yet, but uh that will come soon, maybe next week and or over the weekend, because we've been working on that. As I tell you, it's like this is an active development right now for us. So this is what the soft laser app template is all about.

A

uh Basically, what we want to do is we want to improve the self application development in in non windows os. So by non-windows os I mean all the type of flavors of limits where bs code runs and and macos so, which is basically also a linux.

A

So that's the idea because my laptop is is: is linux, so I run ubuntu 20. I think in laptop and also this laptop is huge, so I don't take it out of home. So much it's like it's like really too heavy. So usually what I take out is an old macbook pro, like I mean really all like 10 years old, that is not running mac os running also ubuntu.

A

I did this out of necessity or of being able to spin up a new project, really quick or as quick as I can and uh or as far as I can, and and then deploy and test it or show it to a customer. So I usually felt handicapped when I was producing visual studio because I use quadros a lot and I truly mean a lot. So I do like the factory in the factory refactoring and everything is a shortcut, so I was for me it was impossible to say that I will use visual studio code.

A

Then I ask davis and I think also mark miller if we can do something like for cod rush in in this call, but they said like well like we're mixing visual studio right now. So good luck with that, uh so uh we decided to do our own simple implementation. It's simple, but it's simple enough unusable!

A

So basically, uh let's go back to the powerpoint or impress that's what it's calling linux. So that's what we have about the template break so now, let's go to know it already so here. Finally, since I was able to record my account, uh this is bullish by me, so the handler is the same as the one in tegarim reading, which actually is mirage.

A

To tell you a little bit of the story about that. Is that about that username?

A

Is that my neighbor, a really good friend, uh won a contest playing fifa 94, something like that and he got like two internet connections for a year for free, so he gave me one and his username was mirage and the second username was mirage backer, which is again so I've been using that uh username for really long time so well, uh since this is not published in a private new xp like um like we used to do before for the same framework templates and everything you can get everything from here now, so that's kind of really cool.

A

So the thing that you need to do to install these on your in any of your os, what does net is running is just copy this line and execute it in the command prompt or the console or whatever you have.

A

So basically, what I'm going to do right now is. I can run this, but I already have it so it will not. It will show that is running already. So, let's find this here. If I place this, it says this already. So nothing to do so, let's see, um basically in order to have the console actually available to the new command.

A

What you need to do is in whatever os you are using. You can see like all the supported os in here, so mac os windows and all these labels of linux. Those are the biggest you can make it run in any other like, for example, in anything that uses a snap as a package manager. So whatever linux version you have because there are thousands of them. If you use snap, then you just from the snap and you will have the dot net cli.

A

Basically, so in my case, I'm running as you can see here, actually one two: twenty and we'll do 20 22., so uh in general, like I was like it was hard to move from it to from dotnet.

A

And then from that site, when the six is just a job, you just change the number and that's it, but I strongly recommend that you should have both sometimes and vote as the case when, when, when you sell the cli, so everything here is is deprecated. So to be honest is like, if you want to run.net in anything, that is not windows, try to install the.net, sdk and runtime for five and six and you will be covering for most of the modern or new stuff.

A

So, okay, so knowing that, knowing that, uh when that that you have the dot net c life on it, then you can run the dot net commands like dot net new, for example.

A

So um that's what makes uh make this available for us in general, so uh once that we have the runtime running and the sdk running? uh Well, if you have this code, this also that can also be nice. So let's go to my impress presentation so now, let's do a small game with ubuntu so that that is kind of a lot of fun, at least for me.

A

So let's go to change directories to documents. I will make this like super big, so you can see it so uh documents, and here I have, I think.

A

I have a bs code folder and, as you can see the list, all of those are like tests that I've been doing before. Maybe I will just keep this a little bit smaller. So let's clear this so the first thing that we're going to do is we're going to make our directory so mcad.

A

No, let's do it even better: let's do it even better. Let's what is heat.

A

uh Let's do it from here so file new repository is going to be here. So let's call this the linux standard.

A

And let's initialize it with the readme and then you did not it's going to be before the studio.

A

And license is mit, so create, and now let's show this in the file manager and bam. This is empty. uh What we need to do is we can either like ctrl l and copy the back and then let's go back to the console, because I can do like here like open terminal, but I don't like this terminal.

A

I, like this other terminal, infrared that I have here. So let's go there and we're there so see the same two files. So what we're going to do is, since we have the template already installed.

A

And we did that with this line, if you just don't, if you just run the first part without the version part it will, it will install the newest version. If you want any specific version, we just would complete it with the numbers, and these versions are the version of the template.

A

It's not related to the xaf version, so I will show you a little bit of how you can handle that, but um it's not related to that. It's not that this is sub version, one. It's not it's! It's the current version of xaf! So let's come here! uh Well, let's go to the documentation. I spent a little bit of time writing this, uh so this is done it's installed already.

A

So if we want to get an application and set the name, we can do this, and if we don't do anything, it will take the name of the folder. So let's get this command from here copy and paste it here so bam.

A

So, as you can see, here is like the template, the template. um I need to fix this this this is, should not be here. So this is a soft blazer application, including this is using xpo and it's including all the modules, because there is no wizard. There is nothing like that in here, so it includes basically everything. So it's easier in that sense. If you fail to remove, I guess uh sometimes, then adding something.

A

So if we do ls to use the directory, that's what we have so we have a bash space to run the application. If once we want to run it uh these directory props, which is really interesting that I will show you a little bit later.

A

We have the solution and then we have you know the module moving blazer, the laser application and the api. So the first thing that I'm going to do here is like dot dot net, restore that will take. We look for projects or solutions in the folder and will restore all the knowledge that are needed. So for this you have to have your.

A

Your nougat source uh from devexpress, like the the one that they give you in the download page you have to have it already set up in the cli, so uh everything is restored. So now, if we want to.

A

uh To open this in visual studio code, you just write code and then dot and slash forward slash. I guess uh we have a different name for that in spanish, so I I'm always confused in english, so that will basically open visual studio code in the current directory. So, let's hit enter uh here. We have it. We have visual studio code, uh everything is restored already.

A

So let me walk you through a little bit in the things that that well, that we have here so uh first, you will see this directory.

A

uh I cannot make it here in here, but this is bs code directory, which is a hidden directory, and here you will see here are all the snippets that um are needed to to execute like somehow like all the snippets of code first, so it's as as closer as I I mean as we were able to make them. uh There is a lot of room for improvement.

A

We can even create an extension just for xaf development, but it takes time, but uh this is the third graph. Let's say that uh you can modify the delete and add more if you want. These are locally set up for your preex, so if you open a new folder, they are not going to be there. We didn't make them globally, so we can share them in the in the template.

A

So beside that, you have this. That is really interesting.

A

We have this pro directory, build props to share build properties within all the projects. So if you want to change xas version of developer express session in general, you just change this number and it will change through all the applications in all the projects. Here, if you want to change the target framework version, you just change this number from five to six, for example, and.

A

Basically, it will work for you, uh so I did that to make it easier uh in general, because if you check the practice, let's open a project.

A

See like the and the target framework is a variable, as you can see here, and also the framework for developers. That is also available, as you can see here, so once you replace those in the directory build props, everything will be updated, so just one place to update everything.

A

So now uh less well like this. Well, there are a little bit more things to show you. So, let's see uh one of the. We did a few changes, including this template, uh to make it easier, because there are a lot of steps involved in deployment in linux or determining anywhere. So we wanted to to make it as short as possible to streamline us as much as we can so. The first thing that makes this a little bit different in a normal application is, I think it's in the program.

A

I I think I even forgot a little bit about this is. Is this part uh when we create the host builder for the application we create, we add a new file, um basically in dotnet core five and six, you can well. That can happen in the same way in a different way, because also it's possible in the framework.

A

You can split your configuration file in several files. So basically, what we're trying to say here is that usually including the configuration uh hosting js and mix it with the application settings. So let me show you hosting yes, so, basically, this is something that doesn't come with a normal x3s application, which is any any asp.net core application, five or six.

A

When you start them, they are listening to to the local host. So you can make only calls from the same house that you're running the application. If you do a call from outside, even if you're like, I think it's public, uh it will not work because the kestrel server is not listening to that uh to any other ip, but the localhost 2701 or localhost as a domain.

A

So we did this so you can like easily, even in in once the application is deployed. You can make it listen to other leds and other ports uh because especially like, if you're using, if you're, not using iis, if you're, using apache or ndnx. Basically, you will have to do a reverse boxing, so the reverse proxy. What it does is it forwards the communication from outside from a server that is visible from the outside to a local, internal, ip or port.

A

So if you deploy in something like, for example, apache- and you have visual services um before hosting sorry, uh you need to, for example, you have your application. Each application should be in a different world and the apache will be forwarded to those ports. So it knows where to go. So that's why this make it really easy. If not, usually you have to compile the application again and redeploy it so that sucks in general.

A

So to save time we put that in a file, so we can change the room and we just stop application change number first application again and it will be running listening to other ips or other ports. So uh that's kind of really really good in that sentence like it's easier than compiling.

A

So let's go back to program here.

A

So basically, that's what we're doing here we're mixing that uh to listen to more than one uh the one ip or one port. So also, if you're going to run, for example, if you're, usually when you're producing linux, you will always have a real web server outside in front and it will be forwarded to the application. So um that's kind of basically the only thing that that you need is like uh to be able to sell it in a port and that's it, but also if we go to the startup.

A

I think there is another change in here.

A

I don't know anything here or using the program.

A

Well, let's check here.

A

No, then, I think it's in the program yeah, oh here it is just in front of me. Let's, how do you make this bigger view.

A

Well, I cannot see to make it bigger with ctrl shift and the on the wheel in the mouse, but anyway. So this is another change. Is that the use url uh is said to listen to the urls that we set in the hosting file? So basically that's how you change the portal, how you change the ip that you're listening to so as I again, as I said, like you, don't need to add more than one url, not one for http and what for https, because usually in linux, you will never expose this directly outside.

A

It will be always.

A

Behind another web server like apache or basically nginx so, okay, that is one of the major changes I will say um now. Let's talk about the scripts like once, you create the application. We've got the new task laser. uh You will get a few things, so we talk about the directory pro.

A

We have this command, which basically will go to the application directory and then compile this and run it. This will give you an error, because the updater is not running. If you run it like this, you mean that you're running on release. Basically, so the updater will not be executed, because the updater is waiting for the for the debugger to be attached in order to create the database file so also- and what is most important here actually is this uh space, which is install a service in ubuntu.

A

This will work in ubuntu, 18, 20, 21 and 22. So like at least four versions, then we will include more speeds like to deploy in red, for example, incentives uh like we'll try to include like, as maybe in the like, depending on the on the audience.

A

As many distros as is needed, but wound is one of the most common users and one of the most common disorders, because it's really like really easy to use. Maybe centos and headers will be like you know, maybe as big, and I guess we'll have to make a version for oracle linux because we're like it's kind of popular in latin america uh somehow so if you want to run oracle applications using xts that run in oracle linux, so um that that will be something to include here. So basically this what it does is.

A

This is like kind of small, but it was really tricky to develop because of the the permissions user and so on and so forth. So let's go back here.

A

And well like, if you want to deploy an application in in linux, you just have to follow these tutorial, so the tutorial tells you like what you need to do, so you need to run this command to create this command. Fill these values inside of a console which talks actually then set these values this. Actually this is not the full file, um so you need to basically fill all these variables and then start enable the service start the service and verify that everything is running.

A

And then you can see the logs like this. So all of these steps are- and also here I mean they skip a lot of little details. So when you, when you're doing this by yourself, um you do it, then you fail. You see the error in google and you picked it. So it's not straight forward. I mean here you have the big steps, but not all the little steps, especially regarding staff applications.

A

So all these steps here and all the decisions that you need to make are done actually in the script.

A

So see this is basically the flow. The idea is that it will show you some information about what you're about to do.

A

Then. It will basically delete everything that you have this. I mean the same directory before it will compile the application.

A

um It will create a tv update script for you, application start script, stop remove, because you can also install it uh an install script and the status file and then a feed file with all of this, then, what it will do is it will copy everything to the server to the remote server.

A

And then deploy there and run the installer there and create the service file there. The monitoring file from the updater uh start application. So that's a lot of things in general, so here let me show you um we have. This is an ubuntu server and I will just I have like two different states: I'm going to restore like a snapshot, um so I'm going to restart to the clean snapshot with not installed, because I use that for tests. So, okay, it's restored.

A

So what I want to show you is: let's go here.

A

Let's see this is so if we do ifconfig, this will show that jp is 192.168.122.151.54.

A

So save that in memory for a little bit and let's go back to this application, so if you remember the hosting file says that this will be listening to all the ips in the port 8016. Why 16? Because my birthday is on may 16., so I always put that name like people put 8088 when they don't want to use the a report, so I put 8016 because of that, so so well, so it means that if we open the browser, let me just put this here for a while.

A

I hope I'm still changing the screen and everyone's paying attention, because sometimes uh in linux, like assume, stop sharing for no reason. So I hope that that it's not so boring that no one is paying attention, but anyway, uh let's see so if I type dot url here see. This is the url I'll show you in the virtual machine and if I refresh there is nothing there. So nothing is running.

A

So let's go back to the impress presentation, so that is the demo on ubuntu, how you create the application and being.

B

A

And not in a non-windows machine, so now it's going to be a little bit of a demonstration about the shortcuts. So we have the application here. uh Well, let's make a persistent optic. So let's go to the domain. Business object, folder, let's add a new file. This will be customer cs and what we will do is well, let's go to the documentation, and here we have all the shops, all of them needing the shortcuts that we have in code rush already.

A

So if we want to create a domain object, if this is the only one that is not in portrait, is x dom so let's see x dom and then you expand and there you have it so so far so good. I don't know why this will studio show like this uh wrong, but anyway.

A

So let's expand that again.

A

So, let's and this will be customer and we have a customer and then this will be linux. Standup.

A

Module business object so now it's in the correct namespace. So now, let's add a few properties to this.

A

So here we have only like one x prop uh that we can do for all the that we can use for all the properties.

A

Sorry, uh so let's do a few properties, so is we're going to do x prop this will be name and then, when we change see, we have a selector of type. I have included like all the primitive types, so this will be the same and let's see.

B

A

Customer just change and we set the stream press enter and that's it so.

A

Then, let's do one more uh exprop active and this will be- I forgot boolean, but I can fix that really quick. So if I want to fix that, I can go to the snippets and look for the x prop so here and so here we have a list of the possible choices of types. You can include the types that are in your application. Actually, so let's do boolean.

A

uh So let's go back to the customer class and it's prop active and now we have boolean see nice. So let's open the terminal- and let's compile this just in case.

B

A

I guess we need system uh or did I spell it wrong.

A

Oh yes, it's bull.

A

Well, I will do like boolean system.

A

And let's compile that again.

A

ah Here is like uh this was name, not customers. So sorry for that, so another extra, it's probe.

A

Hit enter because enter is in the for this stuff and this is string.

A

Okay. So, let's build again so dollar bill.

A

And well it's working, so I'm going to uh do like just a few more shortcuts. So it's going to create a controller, so um this controller dot cs.

A

So let's go back to the documentation and for a view, controller is.

A

uh Where this is from, it should be controller view. So, let's see I need to update the documentation, so soft controller view the same as encoders. So this will be this controller.

A

And this will be the notes, stand up.

A

And small module dot um controllers?

A

Okay, so here we have a view. Controller is exactly the same as a normal view controller. So we also have short for the action. So I need to update this because this is backwards and also this is backwards. So let's do just a simple action.

A

So here like actually this, this is going to be a little bit interesting. So when you create an action, you have to create a handler separately and everything, so we use a different approach. We use type methods for this, so let me go to the constructor and this do like xas staff action simple.

A

This will be my actions.

A

And it's going to do nothing, but uh basically what I want to show you is that see the body of the hands that is inside of the constructor, so we created a private, an internal method inside of another method that is supported from, I think, net uh official, six or seven, I don't know which version I think very nice at the moment, so for every action every actually includes everything in private methods on and also c.

A

You have a region here to know where your the code for your item start and then it includes the declaration of the action and the methods needed to the explanation to work. For example, the the pop-up window uh requires um like two methods at least to work. So if you want to do another one, for example, let's do a soft action pop-up window and see this is like more complex.

A

I will leave it as that without changing the name or anything so c like is way bigger than the simple action, and it includes also a little like thing that if you want to create a leaf, so let's remove this, so this will be type of customer.

A

And the type is not here, so we need to import namespace.

A

So how do we name this? uh It was customer, I think, yeah, so.

A

Okay, so using this so okay, so we have created that and then we just need to add that to to one of the variables here. So it will be.

A

This one so see here with the e and the the signature of the method is a little bit different because usually their name really simple, like center and e like arguments something like that, uh but in here basically we change the name, because there are, they can be several east or several centers because see they send it on the simple action, uh his name, my action center. So his name is the same as the action, because we can have several like uh signatures that are basically the same.

A

uh If not, we will have an error that the the name of the variables are repeated and, of course you cannot have that. So then, we'll do like this view.

A

It will be the this view that we just created. So, let's compile again.

A

This is kind of scary, because it's the first time I do it like live so, but anyway, it's part of the fun okay, so we have like a domain object. We we have a view controller with two actions, so that was like. I can tell that that was everything for the shortcuts.

A

I mean you can see them on the list and check them yourself now, it's time to have more fun. So well like let's go here and where is that is here, so we have this machine. This is the ubuntu server that is running also, my computer beside the windows computer that is running so my computer holds like 10 machines. At the same time, sometimes you have to know where I am so.

A

What I'm going to do is I'm going to ssh to the to this, um so this machine ssh is the console communication that you usually do with servers. So, let's uh I will just leave that in there um and I will because this, like the font, is really small. So it's it is hard to see.

A

So I will ssh from another console. So we have this console. That is the one that we use when when we created the project, so let me create another console.

A

So here we're going to ssh uh the user, which is for j also and the p. So if 192 168 122 154 and then we need to know the password for that so already, so this is on the one play team. So, let's clear we don't have anything here, so the directory is empty.

A

So now let's go well. We can do it in different ways. We have the terminal that we have here where we are doing the the build or we can do it from any other terminal. I will do it in the terminal that we used before to create the application, so I can make the phone bigger so here so let's go back to the documentation and now let's do the deployment.

A

So uh before you do the deployment there are a few things that you need to do. So if you want to run the scripts, you need to give them permission to run so, for example,.

A

This is how you add, executable permissions to the front script, and then you change the folder and to where this file lives, and then you change mode to that file. Also, so I will copy this.

A

Because I don't want to change permission for the wrong folder right for the wrong script. I don't need it right now. So let's do change folder, so they just episode. That's the where the server application leaves. So let's go there.

A

We do a ls, and here you will see the script. So we just paste this, and now we have executable permissions. So sorry, I was eating peanuts and I think, like I have something installed in my throat.

A

So let's uh go here and copy the the command to the policy. The command is kind of really simple. This is an example of the command, so actually this is the command that I've been running like all the time to test. So you need to when you do like this. Is that you're telling like execute this script in the local in the local directory?

A

You can also only use the script name if you, if you want, then the ip or the host name or domain of the server the user in that in that.

A

In that server, like I mean sorry, the the remote user that you want to use to connect to the server and copy the files and run the application and then the path where it's going to be installed, and then the last parameter is that if you need to run the update, yes or no, so here, you can see like what. uh What is each parameter? um Basically, some since I'm super lazy, I'm going to copy this.

A

And paste it here so remember that I open the browser- and there is nothing running here and this. The other terminal that I have this terminal is connected to that server.

A

So, let's clear this and let's do some magic. Let's hope that this works, like you know, like demo effect, so enter. So here's a little first uh review information, so the application that we're going to the application that we're going to install is uh saf linux, standup data server, the id where we're going to try to connect is this ip.

A

The user name is, is host in this case and the remote path is home hot, which is my home folder we're going to run the create, updated schema, yes, and if we want to continue let's press y and hit enter so now it is asking us for the remote password for this user, so I will type the password.

A

uh There are some security considerations here. uh It's prompting the password many times, because if we save it on the script, somehow it can be in the history of the console here or there. So that will be a security issue. If you check that you will see the password there, so it's better to ask for it. So right now we're compiling the application.

A

You can see you can modify any of the parts of the of that on the screen and that's it is like.

A

It's going to take a little bit.

A

And then basically will uh now you need to see it. It says like for a little while, like this, it will copy the files to the server using the user. Watching now it says that the remote password will be asked one more time to install the app as a service and well before it installed the apos service. Since I said yes when the when it prompts, if I wanted to run the the the updater so see, these lines here is the dev updater. So closing the data is updated.

A

It's going to be silent mode off, so we're going to see what is going to happen. uh This would be like one directory behind and the name of the database is the same name of the application is right now this application. This template includes uh sqlite, so you can test like really fast. If you want to include something else, I think we'll include the nugget for postgres and mysql, so you just have to change the connection and that's it so hit enter.

A

If the database is done so we hit enter again, it's changing the permissions to the files, so it makes it executable and everything, and it even read permissions to the database file, because sqlite is a file, and now we just need this last part is asking the command. I mean the sorry is asking the password for the user one more time, because it's going to copy the service file and start the application. So we say yes, I know with nothing. Yes, we say like we type the password and right now.

A

It's also checking something I'm going to talk about the pattern, a little bit. It's installing some packets that are needed by the framework itself. This is this package that you're seeing there uh is related to one of the the the post in my blog.

A

So the server that we're using to install the application is totally clean, doesn't even have the frame or running when we compile the application with this script is self-contained, so it means that the parts of the framework that you need are going to be copying the application itself. The normal application, without like anything like extra, is like 86 megabytes.

A

So it's not that big, including the framework itself, so you don't need to have the framework installed in the server it's already included in the application, but even when you have a self-contained application, or even if you have the net framework running on the sdk or the runtime running on the server, you will always end up with this problem.

A

When one of your net, 65 or n4 application uses something graphical, you will end up with a gdpa, gdip libraries missing. So one of the things that the script does is even install that so to fix that you just need to run basically this command.

A

So basically the strip is making sure that you have everything that you need in a cleaning server to to deploy your application to android. So even about that, this is not related to sas itself. It's more a problem of the dotnet framework in general.

A

So let's go back here to the console.

A

So it installed that part that was missing the server because the server was clean.

A

Then it started the service and the service is running and it disconnects. So now, if we come back here and we refresh the application is running so, let's log as an admin- and we should see.

A

See we have customers, customers and the property so ho chi ohera.

A

Let's make a new one that is going to be this.

A

New one javier new ector, um jp uh john port, so we have here the customers and we have the action. So this action is doing nothing basically because we didn't add any handlers to it. But if we click this, we have the pop-up with the uh with the customers. It's a list view of cosmos. So three, you know like uh tricky strokes and we have the the pop-up even it's shorter than in podrosh. It's even way shorter than um this is kind of nice.

A

I mean, if you're, using linux, especially or mac os or something so now. If the is the difficult test, so uh this console, we don't need it. So I'm going to minimize it I'm going to go to the other console, which is this one.

A

This one is the console that we are have connected to the server. So if we list all the files are there, as you can see, there are several scripts. This is the one that we run. Basically, when we deploy the application, we created a stream. We copied the server and that's the one that uh do everything. So if we do like uh nano, which is the text editor for the console uh installed- oh it's not it's not known so.

B

A

No, this is what we did. Basically, we installed the everything that was missing this, which this is the listing which was missing. Actually, then we changed small to make it executable. Then we copied the service file and then we enable the service. We start the service and we show the status. So that's what we actually did after copying the files and uh we ship it there and everything.

A

So if we run like status.

A

I will ask for the user the password for the server so and now we see the status that the application is actually running. So we know it's only there so.

A

So now well, this happens sometimes that I cannot type so, let's exit this exit exit there, you go so clear. Let me connect again.

A

uh We clear this so now is the is the is the hard test. So, uh let's make.

A

Let's put this here to the side and let's put this console in the other side, so right now we know that the application is running so refresh. Is there? Is there so, let's restart the server or, let's turn it off, actually so shoot down so sudo?

A

Yes, it needs to be executed, like a super user, uh shoot down.

A

A

Oh, I didn't set it right, shoot down now and see uh you didn't see it because I, like you, didn't see it so as soon as I shoot it down, the application will stop running. I refresh this is dead. This is there. This is there that is dead, but here we have the virtual machine control. So if I start the virtual machine.

A

See the server is starting.

A

And if we refresh oh, no, we need to login in the server, so that's me and see as as soon as I log in the application started. So it's beautiful uh here we have it and the application is still there. So when we reboot the server, um the application will be honest and that city site is fully deployed as a service. We need to put a patch or something in front of that, but all the steps that are that it takes to do this are done for you with the script.

A

Just one line even run the data, so so everyone will surrounding the updated. Not just me so well that that was uh everything for this for this demo. uh Let's see, uh I do have another demo, so I guess I will bore you for a few more minutes. So now, let's stop shaving for a little bit, and I will move from here and I need to share the other machine.

A

So one second.

A

This close scrolls everything your machine, all the projects I have. I was using files so.

A

Let's share the screen, if I can so.

A

Share and we're going to share windows, so we are now on windows, which is a virtual machine in the other monitor uh in my computer, as you can still see here, this was the one that we were running before so now. Let's, let's have fun in windows, so you know that in windows.

A

A

Let me make this bigger, uh we have.

A

A

Then, oh, this is the this. No it's not! This. Is this one, the window subsystem for linux, so you can basically run linux installations inside of windows as virtual machines and to have a seamless interaction between both.

A

So I think I have a few, maybe uh so one two yeah I have one to 18 and ubuntu 22 here, so I have like two wsl machines. One of the wsl machines is this one and I was holding a test just before we started. So let's go a little bit out of this folder.

A

So here I don't have anything. I have only the the the test application that I did. This is the ubuntu 20 that I have so, let's do the same in here, so you can see that you can basically deploy in the same way. So just what I'm going to do before we continue is so this one is this one here you can see. This is the little machine that we were using before I'm going to restart it.

A

So let's go back to the view snapshots and let's restore the clean state, and we will have no application anymore.

A

So uh it's kind we will use that server also to deploy so again. Let's make can we make uh this bigger? uh No, I think that what we should do is we can start the terminals. I love this terminal, so anyone because you can change a lot of things so we're going to start a new ubuntu 20.

A

I think I hope is that one.

A

Let's check, let's check, if I, if I have the size there, then let's see ls. Yes, I have the test application left, so I will close this. No. I will leave it open just in case, uh but in here I can make the the the font bigger like doing this so here so.

A

A

Let's make a deal so this will be like uh dear f, w wsl.

A

And yeah we have that director so change together, so wsl here and see here is this empty like there is nothing there and again, let's go back to the documentation and we're going to copy we're going to start the this is already so if I copy this.

A

And paste it yourself is already there. This is way slower because it's a visual machine inside of a virtual machine inside of a vehicle machine. Oh no! It's not! There.

A

So I thought it was there, but anyway.

A

So again, what we need to do is uh do those new soft places.

A

And we will have a blazer application that is named like sub wsr, so ls we have the application there. So we can do the net restore.

A

And it's well, it didn't take that much, but the first time that I did wait wait longer because you need to to copy all the nodes to the local caches. So this is the jury of wsl. Wsl have an amazing integration with windows. So that's why it's called windows subsystem for linux, because basically the integration is amazing.

A

So I in the linux machine right now in the windows subsystem for linux, and if I want to run visual studio code, I just write code and do this to run it in the local folder, as I didn't name it. So if I hit enter it, will open visual studio code on my windows machine pointing to that place.

A

So uh here is the application that we did and basically what I want to show you guys is. We can open a file, let's open the file here, and I can tell something like this: like reveal files in explorer, so it will show a shared folder like with the linux machine. So if I copy this.

A

And then I open this on the studio.

A

I can, if I'm in windows I can edit the application on on windows, or in this I mean sorry on visual studio code or in normal visual studio.

A

So that's like amazing in the sense that I can use in. If I'm in enos, I can use sorry in five minute windows. I can use linux.

A

I can use visual studio code and um I mean way more choices like when you're in linux. But if you're in windows, you can have all the mixes that you that you want. So, let's see.

A

Oh adam and and and they had to run so well, it's okay. So uh here what I wanted to show you is that we have the application and we have the same structure. We have the directory, props and everything. So it's even more familiar for all of us because we come from visual studio right. So um that's it! I don't have to show this because I showed it before so.

A

What I'm going to do is I'm going to ask.

A

I'm going to add a property just here for the user. I don't want to do as much or maybe I will add the main. Note least I have no tests. I don't know if it's going to run, oh it doesn't show. I think it's still loading.

A

Yeah, it's like graded out, but anyway. So at least I don't know why it happens, maybe because it's in a shared folder somehow uh but there's.

A

Something here to this so xpb.

A

Is this cool? Of course it is so that's the only thing I'm going to do here. I'll save this uh I'm going to go to the console again and here is like we need to go to the uh the.

A

Laser server folder like we did before so yes, yes, and here we have the list. We have the same, install and everything so we're going to change mode plus x to the install.

A

And now we have execution right so in here just uh a few things: the windows system for linux. When you install it when you just open it, uh it's a little bit empty. So there are a few things that we need to take care. Yes, let me move this here, so one of these is that it seems to be an error in, but they don't.

A

Oh here is the g-fip uh library on the windows subscription for linux. You know they want the ones at least if there is a mis-configuration there. uh So, basically, if you need, if you want to do this as the same as I do it, I did one more step before which is running one command. uh The the issue is in github. You can see it and it's also in the repo information. So he said that if you're going to use wsl one or two, I should put a clarification on this ubuntu.

A

You need to run this command in order to fix the seat library, because otherwise you cannot save the files to copy to the server.

A

So that's the only thing that you need and you need a sh sh pass. You need in the in the windows system, for linux, from like uh computer or virtual machine and in any linux machine if you are deploying from linux. This is what sends the password to the server, so it's needed um so we're one step uh a way to finish. So, let's see, basically, I'm going to go to the other console and just copy the command that we did for for that.

A

Let's find the console because I have a few of them, so is this, so the command will be the same because we're deploying to the same exact server.

A

So let's paste that here, let's say yes and then with the remote password and it's going to compile and deploy.

A

Here is going to take a little bit longer to compile, because again this is a the subsystem for linux. That you're seeing is a virtual machine inside of a vehicle machine inside of another machine. So it's like an inception of machine.

A

So it's going to do the same steps I'm going to go to the browser to the in the other.

A

A

And let's go to: where is it here? If we refresh, there is nothing here, because I restore the image like, but let's wait a little bit.

A

And just keep refreshing right now: it's still compiling and now it's shipping- I guess and because that takes time in there because again it's a virtual machine inside of a build.

A

So, let's wait: let's wait a little bit.

A

And now he's sleeping and compiling and everything.

A

And now he's running the updater, so this is beautiful. Basically, let's make this smaller and let's put that here, so let's press enter it's only in the updater.

A

Enter again changing the permission now, let's install the services and everything on let's refresh here and soon soon soon this will be running.

A

Oh, it's not this list, it doesn't exist. No, it's like this and this let's begin as admin.

A

And if we go to the user, remember that we add a property to the users. Is this cool? Of course it is so, let's click on that.

A

Yes, this is cool and save, and that was everything for this demonstration, so uh I know that most people will see this in youtube because we changed the date last time because we have the other meeting within the magnet that we did for for maui, and this is supposed to be the web api, but instead we change it for linux, because we have a lot of things to show for linux. As you see, I hope that everyone liked it.

A

I hope that you can download the template. You use the shortcuts we, we can add that I mean add more to that or make it better. uh Please join the github repository downloading it, making better than a full request. We're looking forward for that and well that's it. That's everything for this meetup, um I think, was a really good demonstration, nothing exploded. So thanks for joining and see you in the next one bye.
