A

Okay, we're live, okay, hello, everyone, my name is Martin Dodger and today this meeting is the google Summer of Code evaluation presentations, part two. So we had evaluation presentations part one a couple days ago and now we're doing part two. This is the Summer of Code week of evaluation. So we're done with the coding phase coding phase. One and I want to thank all the students for their participation in encoding phase one, and today we have three presentations. So let me share my screen.

A

Can you see my screen? Can you see the.

B

A

A

Okay, I think it works now. Yeah.

B

A

So we have three presentations today, so we are June 26, 29, teen and the first presentation will be the plugins installation manager, CLI library, by Natasha. The second presentation will be remoting over Apache Kafka with kubernetes features. This will be presented by long and the third presentation will be the working hours plug-in UI improvements by Jack.

A

Okay. So before we start, I would like to ask anybody who is attending that I want to say that we're gonna be taking questions during the presentations and after and you can post your questions to this Gator chat. That's Jenkins, CI, /, JSOC, sick.

B

And then it will belong. Sorry, for my mistake, a negative announcement was different from the other in the Google look.

A

Okay, so the second will be Jack, yes, okay, we'll do that.

A

Last thing, I want to say is okay, so the way this goes, the student will present their there will do their presentation and then mentors will have a chance to comment or ask questions, and then we move on to the next presentation. So I would like to now we'll stop my screen share and.

A

Now I would like Natasha to present us the begin installation manager with the a CLI, which is your project, mmm not sure the floor is yours.

C

Thanks all right um I'll go ahead and get started.

D

So hi, my name is Natasha stopa and my Jenkins google Summer of Code project is the plug-in installation manager, library, slash CLI tool, I'm, just a quick overview of my project, they're sort of two main parts: there's the CLI tool, which will allow users to have more control over which plugins they want to download and use for Jenkins instance, and more easily see information about specific plugins and then there's a library which will sort of serve as this unified way to do plug-in management and then yeah.

D

Some of the key features will be that we can download plugins before Jenkins starts and then it'll also offer better plug-in tooling.

D

So first I want to just motivate my project a little bit. This quote was taken from the offer plug-in management tooling, epic, that this project is based off of so everyone is reinventing the wheel partially implementing the quote-unquote details, a plug-in management sign, metadata, artifact, checksums, plugins, detached from court dot becomes obvious. Jenkins should provide adequate tooling for plug-in installation outside Jenkins live instance, so plugins are key to the extensibility of Jenkins, and plug-in management has been somewhat of a pain point.

D

There's currently lots of different ways of doing this, each which has their own strengths and weaknesses. A lot of people have been trying to do the same thing multiple different times, so the goal of this project is to really streamline plug-in management across the different components and then also offer additional features, such as viewing security warnings and available updates.

D

So the first part of my project, we kind of started by trying to pull out plug-in management from core which ended up being pretty difficult. So you probably can't really see this visual, that's, okay, it's more just for visual purposes, but each box represents a class related to plug-in management, and then each line in that box represents some method and all the red lines are dependencies. That would also have to get pulled in or refactored and then additional boxes same thing are just related classes or things that would also have to get pulled in.

D

So this ended up being a much more difficult approach to kind of start with, so we ended up changing gears a little bit and trying to go about this a different way, but I just wanted to bring this up, because we did look at this, but it ended up just being very complex with the dependencies.

D

So a large part of phase one has been focused on converting the installed plugins bash script to Java, and we wanted to start here because this there's a lot of limitations with this bash. Go it's difficult to maintain and extend. It doesn't get all of the current up-to-date data from the update center.

D

So there's kind of two portions, as I mentioned to this there's the CLI options and then also the library I'll go over each of these and what I've implemented so far in a little bit more detail. So currently, these are the available CLI options. If you were to download and try out the tool today, so the user can input a list of plugins, either through the CLI or through a dot txt file that just contains a list of these plugins and their versions.

D

The user can specify which directory they want their plugins to be downloaded to. They can also include a jenkins for file, and then they can also view security warnings for all plugins, the library so far works like this. Basically, first it tries to find when installing plugins, like which plugins are already installed or downloaded. So first it'll check the plugins that are in the war file. Then it will look at plugins.

D

If there are any plugins installed in the specified directory, then it will go ahead and actually download those plugins and their dependencies and it'll ignore them if they're already downloaded or installed or upgrade them. If there's an existing version but what's required, is a higher version than that and then it'll download those plugins from the URL either on based off of the plug-in version or if the user can specify also a version specific specifiers such as latest or experimental.

D

So we'll go ahead and download those and their dependencies and put them in a folder. So I have just a quick demo of kind of how that works.

D

um Okay, so I have my char file. I can go ahead and specify a list of plugins here, I'm just specifying one right now and then I have also included my Jenkins War file.

D

So, as you can see, the plugins will actually start downloading, we'll go ahead and check and see what plugins are installed in our war file right now, I just used kind of the default plug-in directory, and if there isn't one um this library we'll go ahead and create it so right now we don't have anything in our plug-in directory and then for each plug-in, we'll go ahead and grab it from the URL and download it and then for each of the dependencies go ahead and do the same thing.

D

Okay, so I think downloading. All of these does take a little while, but yeah you can see that. Basically, if we have an installed version, that's less than what's required, we'll go ahead and upgrade that and then, if we have an already installed plug-in we'll go ahead and ignore that or skip that too.

D

I guess I also want to add. I did present this on the platform sig meeting last week and we had some issues with recursively resolving dependencies and that has since been fixed.

D

Okay, so while this is downloading, I have a couple other things: I'll go ahead and share. So let's see.

D

So we just recently released an alpha version, so feel free to go ahead and try it out and give me feedback looking forward to hearing more about what you guys think and then just in terms of next steps. So far, it's very much a work in progress. So there's a lot of work to be done yet, so we want to make parsing more robust. We want to add a full support for actually viewing all the security issues and available updates.

D

We want to support different input formats and incorporate into Jenkins Sarkar, so I did just see. Somebody asked a question sorry about about how compatible it is right now with Jenkins stalker.

D

So that's something I was actually working on last night and it's not quite there yet so I think some of the defaults that I've set for specifically like if there are plugins that fail to download I have like a default set right in there right now to just kind of create a file in like the current working directory and I know that that fails with Jenkins stalker and then there's also a couple other issues with right. Now, in the current installation scripts you can basically getting the update.

D

Centers is set via environment variable and I have a hard-coded right now, so those aren't changeable, but that's something that we're aware of and we have a juror ticket for so that should be resolved sometime in the near future.

D

Okay, so, let's see I think that those are probably done downloading now. So me up so I just wanted to go ahead and show you we have all of our plugins installed and then I did forget to show you a my plugins dot. Txt I did also include a failed plug-in that should fail as well. So this is the part that I was talking about that. Currently there was an error in docker. Basically, we create this text file. That includes like the failed, plug-in and I know. There are some issues with that.

D

So yeah I think that's pretty much. All I was going to show today yeah we have meetings twice a week at 6 p.m. UTC. You can check out the repository and our guitar channel yeah. So are there any other questions or feedback.

A

Actually I have one technical question, another sure yeah.

D

A

Happens when the download center stops responding in the middle of the operation.

D

Are you talking about like if the plug-in is downloaded like halfway or are you talking about like if the URL can't be resolved.

A

Sometimes the download center goes offline for uncontrollable reasons, or maybe, let's say I'm, on unreliable internet connection. How does this script behave in that case or how do you plan to make it behave.

D

Yeah so I think in a case where, like you, can't actually access the download center right now like or save, there's some like error with, like actually downloading those will just print. You know that there was like an error. I think that we probably in the future, might want to create like a couple different options on how to deal with that. So one problem would be say you are downloading a plugin that is a dependent for a dependency for another plugin.

D

Obviously, it's gonna be problematic if you can't download those dependencies appropriately, but in some cases where you just want to say view the information about what those dependencies are or available updates. Maybe in that case we wouldn't necessarily want to. You know, stop the whole procedure. Maybe we would just want to say: oh look. We can't access this right now and kind of carry on so I think the goal is to kind of make that configurable, where there's like different the way that would be handled might be different based off of the different use cases.

D

Does that answer your question.

A

D

And then I think there was at least sorry one other question.

D

Yeah so it'd be nice to support maven repository as an installation source, yeah I think that's something that we can probably do, and I can go ahead and create add your ticket or that's something you guys can do too, and then we also had talked previously talked about I think on a different, a different call about supporting caches.

D

That's something that also there's a ticket for we just haven't quite gotten there. Yet.

D

Okay, so if there's no more questions, I'll go ahead and pass it off, but again really want feedback feel free to try out the alpha and just let us know what we can do to make this tool really usable something that people really want to use.

A

Okay, Thank You Natasha for this presentation is so would Christian? Would you like to do you have a few comments? You are the lead mentor on this project. Would you like to make a few comments.

E

F

I guess the project has been going well so far, I think it's really good to be able to see the downloads that are happening, like you know, being all around the tool and at least build the plug-in folder locally yeah again, if you have anyone, has any suggestions or looking to see anything, please feel free to add it to the Jenkins JIRA like we'll medium pull them. Maybe look at that. The potentials, phase, 2 or phase 3, but I, think it's been good. So far,.

D

Thanks I have one more comment: I just wanted to thank all the mentors and/or guide mints. Thank you guys so far for all the support and I look forward to continuing to work with you.

A

B

A

Alright, so let's move on to the second presentation, which is the working hours, plug-in UI improvements, and this will be presented by Jack, Shang, okay, so.

D

A

It to you Jack, it's all right. Yet you have the floor. Yeah.

G

Yeah thanks Marty, okay, I'm gonna share my screen.

G

Okay, for the first for the first two code face and I've been working working out as plugging with Jeff and.

G

Introduction the working I was plugging, it is a plugin which can help people set a lot, a lot of beautiful, set excluded days and the wish which could which clearly scheduled our beauty and we we have control of the times of the days and the beauty will be executed and but but isn't, but the plug-in needs more improvements like- and you know currently, and some some plugins using jelly and I don't know.

G

Maybe most are using jelly to write the configure configure page, and so, if we want to input a date there are there are there are. There is no provided to provided components for us to input a date. At least we could not select selected date. We just you can input a hard-coded date like like a number will slash, and so so we are so. We are actually thinking about using some components, some third-party components to have a selected date and also in setting time ranges and challenges is just the allow of your challenge.

G

So so, in order to find some usable UI components, some some helper libraries- and we are thinking about using reactive and why using reactor and case using reactivity, are some powerful date picker and we could pick a data dictate like a magic and we can have a slider to choose Tammy ranges and also we got some ability, design, the Amazon II, a flexible, responsive, UI like and chai show some part of my channel, and maybe that was make it clear, and here is what it looks right now and for some range part we can have a slider.

G

You can use a slide that you select the date and the people could import data just type in, but also we could use a slider just to that time and for excluded days we can select a date, use the time picker, and this is a reactor components component and the weekends lactate or yeah.

G

So she, yes, so did you like this and we needed to type that we needed to type a hard coded data string like an evil. Sometimes it's easy to type a wrong date and yeah.

G

Also, if we, if we use react, we also could and take advantage of web pack and if we use webpack and the user interface, we rotate it. You know in in common in common ways of develop some JavaScript projects. Some of your functions will be leased to pollute the global namespace and like something. If you import some libraries with Scripture and, for example, you import and jcotton, you import the query and in the global namespace all the place, could you could use jQuery, but we actually does not expect it.

G

But if we write a reactor project with webpack, the output will be wrapped in a in a in a function and that that is excluded exactly the instance today yeah. So so our project won't pollute the global namespace. We want to affect the other plugins.

G

Also, if we want to use react, we are not using, so we are not using jelly and sometimes stapler anymore, and we need we need to split our front and waist back end, no a separately to separate them. So we find that we found a solution to divide it divided the front end and the back end.

G

We just did during J's by setting setting and mount point in the Java file when you Joey is a is an en is an simple tag with a unique ID and again in the.

G

And in there, in the block below we got a script tag and you will import the defile Butte ways webpack and for my disease we got our reactive app mounted into the place. The hinge in the mount point also, we are not taking the advantage of some some some sleep helper function. We have vandalism and animal and we may need to define our own backyard service and I'm doing this learning from and the blue ocean and yeah it's, although he's just using stapler, but it helps it helps me a lot yeah.

G

So we got a function called, do dynamic and a you will. It will receive the request and the Weibull jad its parent URL, and leave a related to the process function and then theta will be returned to the front-end, okay and yeah since set HTTP request and that this is from the front end.

G

Yeah, it's a well it's just using an XLS to send a post request, okay and actually I'm thinking about doing a common way to develop plugging this reactor and I I, don't know, maybe we may be doing the working hours plugging, maybe the first of all to develop, come and plugging waste reactor so and so I'm thinking about. If people want to design more custom UI, if he wants, you use some of some, maybe more than frameworks like you reacted like a some other headmaster.

G

Yes, for him works, we could think we could produce a way to build to build a plugin means wisdom, yeah, and this is I'm trying to do and but for the difficulties.

G

It's it's just a problem. I found during my chance, if you know or not thinking, is using prototype dodges and to provide just functionality and it's an maybe a library, a little a bit old.

G

It has some outcome that incompatibility with some reactive packages and yeah, so maybe not all the packages, but we may be careful. You should be careful and we actually own. Currently we don't know how many packages you will have incompatibilities, but react takes okay and for next phase, yeah I will completed back-end service and data validation and a fault for now the backend service. It's just the function, just raw data and return data, and maybe we we need to do more things like that.

G

It, like data validation and excluded, excluded, dated check, and also we could do something like workflow refinement and also for these things before we could make a scaffold, maybe a boilerplate or more common way to develop it. Looking this react and and I think they'll be kind of useful.

G

Okay, I shall see more on the user interface.

G

See the excluded dates and for now we could select the base timezone, because some because, if I excluded what date was set and if the people who use the system is divided all over the world and the date come, the data starts in their local timezone will be, will be different yeah, and so we need to define a base time job to put date to started the excluded dates and to make it consistent.

G

Also, there is a preset we could select the date like if we said tell you a warning, Karen nervous, but we could have select a Thanksgiving Day and we apply this choice, no realized choice and you will be automatically set to the fourth Thursday of November, and you know it will in for him for the next occurrence, like it's on the sir, it's on the Thursday November return, the Sunday's that this is a one of the new features like code presets.

G

Also we yeah. There is a dynamic date. We could have select a dynamic date, which means the data is not not statically is it's defined. On the on the owner of the day, you said.

G

You know some some hard days: it's not big, it's not static and then maybe he's on only some some Sundays on Saturday and- and this is what is useful and then also we collect a steady date and the effect if we integrate it into a plug-in development. It will be something like that here.

G

Yeah and for this part we will, we will make another beauty script and we will generate the files into a plugins web app directory and right, but under the Jazz doctory, and we could inject it defiles doing this using this script, and so in that time I will. We could provide a way to how to reload this, the web app being in Jenkins web page, okay, all right and I think maybe there are a lot of questions. Thank you.

G

B

G

Okay, have you reviewed it nice design, language and a change Jenkins chest boundaries should I use, Oh I, know them, but the drinking's design language is its styling. It's it's different. The waist classical thinking, styling and maybe I think we I think the to plug-in.

G

We were we wrote for now, and should it be better consistent in the style with the other plugins or so, although also the clogging I wrote here is not it's not using GRE, it's not using jelly components but I, but I still set the style of the components to the chinking, styling and yeah I. Think that's more comfort, maybe that's more consistent with thinking's.

B

Okay, thank you.

G

Okay and sorry, I'm, Jeff and I should be in bed the name of the plug-in to make yeah yeah yeah we could in by the name, and maybe we thought we could have some hostel number and the to make it unique and the other, the other, the other scripts alum be want to affect us and okay, do we have a plan to adjust the potential prototypes.

G

G

To prototyped in the prototype digest this library, yes, was affecting once inference my development about like and why I am using a library called and D and and called entity and the some of its usability of the map function as conflicts and I.

G

So I give up using the a deep library and I choose to write in simple CSS. mmm Now we actually- and we don't have a plan for now, but oh.

G

Yeah, maybe there are some.

G

And maybe there are some solutions for that. I was wrong about that, but I will I will posted a little. Maybe in the in the in the chitty-chat is a is a poster. It is supposed to wrote by some other people.

G

Is it okay and is there a trend to embed into jinkies web UI, where I frame or do you find Jamie.

G

No, no, no, we are not using a frame and cuz I, cuz I. Think.

G

Reactor provided, as with some ability, called mount ability and we could mount our application to a certain point.

G

G

Yeah I know I, don't know. Father Pro for other approach is like like what approaches I don't know. Oh.

B

Sorry yeah nowhere to say for the question is not comfortable to you. We can just take a top line.

B

E

Are there any people, either in the community or cloud these that can can give us sort of design help.

B

That's for sure, okay, today differently, no a couple of names, so you eat for such helping, get a tray, ascending demo to them and maybe we'll get some feedback yeah.

E

Just to just regarding like look and feel and and styling and stuff um I I would probably feel more comfortable just having somebody do a review of the whole thing when we're a little bit closer. If we could find somebody, okay.

B

Yeah I'll try to help. So if you follow up in the developer man interest, we can just discuss it there, because the best advice for such cases- if you want feedback, just send something to the developer. Imagine peace, for example. You can send them in for this demo. You can send me for the code and you can ask for feedback, and it would be a good starting point for all kinds of session discussion.

A

Okay, um well, thank you, jack for presenting I, wanted to ask if Jeff wanted to comment on or or has, questions but you've already spoken Jeff, but you want to add a couple things or.

E

Yeah say I'm kind of kind of pleased with this, this project over uh overall I. Think if you just look at the features that we want to implement, it seems like deceptively not a lot but there's a lot of things like like breaking new ground with with using react, so we can make use of these these third-party components.

E

There there's a lot of like tons and tons of react components, so that takes some extra time just working with dates and times is often harder than you would think, and so that adds some complexity and I I, like the approach that Jack is taking towards thinking about with the problems that he's found figuring out how to make those things easier for other projects in the future. So I'm really pleased with that, and thank you for your work on them. I'm, looking forward to the rest of gee sock.

A

Okay. Thank you.

A

Let's move on to our third presentation. The third presentation is.

A

Third, okay, so just a moment, first I want to check that I'm, properly sharing and presenting, so that the video is recorded properly. So.

B

Far you're not presenting okay.

A

So I should be hitting the present to everyone button. Is that right, no.

B

Usually, do you want to share the screen? If, yes, you should click the share the screen button, because you.

D

B

Your presenter, but now we just I, see a Jenkins logo token toss.

A

Okay, so here's my screen, yeah.

B

A

Okay, except it's, the loop wait a minute: okay, obviously I'm, sorry I'm not familiar with this I'm gonna stop and let's move on to our third presentation.

A

So third presentation is remoting over Apache Kafka with kubernetes feature by long and so long I invite you to start now. Okay,.

H

Thank you, hi. Everyone, I'm gonna share my screen.

H

Okay, so today I would like to be my my a sub-project remoting over about Kafka. Okay, me cognitive, future and I'm long I'm from Acadia University in Vietnam- and this is my first time participated in. He stopped contributing for Jenkins and five mentors and Roy and Kate lfo1 and support and okay. So.

H

Stories I thought, I lost connection.

B

Maybe seriously.

H

Yeah yeah I. Can you see my screen then, because my truck, my connection is a bit lucky, so so I feel that I'm lost commission so remotely to work traffic. A plug-in is the successful geez kiss top projects from last year and when you have some problem first, it requires users to manually configure the entire system which you'll have to start their own zookeeper cluster traffic master.

H

They start their own Immelt in Asians, and the second thing is in doesn't support dynamic asian provisioning, so our scalability is hard to achieve, and that's why this project it is to solve two problems. The first one is of the box solution to provision classical cluster. The second one is an image agent, provisioning in kinetic cluster.

H

Let's move on so the original proposal is for phase. 1 is Kafka provisioning, kubernetes cluster.

H

Okay, sorry, an Asian provisioning in communities, connector logic using community credential ahem chart to start the whole system.

H

Finally, the version 2 released and what I have done is the first thing: I have implemented community factory adapter class to connect to kubernetes cluster using different kinds of credential. The second thing is a function to lunch, Kafka and zookeeper in kubernetes, using general spec files and after after launching Kafka eyes of people. If we automatically update the URL field and I also investigated our compatibility with community looking whether we could reuse the code in community plug-in, so we don't have to implement Clos API and the end result is.

H

We cannot reduce the cost, though we will implement cloud API in phase two. The last thing is: I have written a ham shot to start the whole system in kubernetes cluster? Ok, so, let's move on to our first feature class efficiently in communities. So in global Africa configuration class, there is a button and when and user can fill out, the communities, information and press a button to start so South, Korean zookeeper, and when user press the button we instantiate a community Factory adapter and fills the German space fire from resources.

H

Then the kubernetes factory editor. We pass the credential to create community client and start the monk Afghans who keeper to start off kinds of people on kubernetes.

H

So, let's demo more demos I have started Jenkins Jenkins server on my local on my local horse.

H

H

A

H

As you can see, this is the zookeeper and Kafka. You re also ins of the previous. It's a before you will have to start their own zookeeper on camera, then put in put the URL here and this future. You can take use community and in little kubernetes.

H

Information so I used mini coop on my local machine, and this is the IP and the port and learning space with Google Casca.

H

Ok, so let's tell the connection its obsessed and I will press a button and if we start zookeeper and Kafka on on this namespace- and it might take a while to download images if it is a first time and I IP a preload, the images. So you guys don't have to wait.

H

In the MOOC and in space, zookeeper is already up and cascading initializing.

H

Let's take a look okay, so it's opening pot.

H

It's obsessed, so why why we went for zookeeper and Kafka junkie. Civil ways are constantly pinging for other pot and after the Cuban Kafka started, it will print the URL here and the URL will be automatically updated here and why we can do this is because I have I.

H

Have a JavaScript on the jellyfish, so here so what this JavaScript does is it will envious of the mutation of the API and it will watch it will watch this lemon and if it's a little change to success when we pass the URL here and then update it here, so you don't have to reload the page. Okay, that's it.

H

Let's move on to the next one, which is hand shot. I will tear down Tara dolls of junkies and Kafka to free up some memory.

H

They did all the service import, so the next one is ham, shot and ham. Chart. Ok, thank you and ham. Shot our hand shot. I have two dependencies. The first one is stable, slash, junkies. The second one is e cubed / Kafka, and for this demo, I will also start a pot in kubernetes to an Asian part to connect to the Yankees master.

H

Okay, so I have a script to demo to demo hand shot what's this quick. This is, if we install the hand shot then wait for Jane keen to come up by using netcat to ping the pot and then copy the password to a clipboard, and then it will use configuration Escott to launch an asian computer on the master side, and then it will launch a revolting, Kefka, remoting, calf asian part, to connect to the computer master side.

H

And then we open the URL in the browser and this the whole thing might take about three to four minutes.

H

And while we wait for Jenkins to come up.

H

H

So you guys can see all serviced so.

H

You have calf:cow have zookeeper, we have Jenkins and kakuzu keeper. Hardly already online Jenkins take a while to initialize because it had to download all the plugins and configuration.

H

Okay, so here's the dependencies, Kafka and Jenkins and I authorized some value for the demo for Kafka everybody start a standalone cluster, only one replica and for the Jenkins I also interest some blocking and some mini squid.

H

This is the spree for agent pod.

H

Surgeon skinned is up, and this could we open the oven, 15 master, one patient, one on the Bravo and because I have a school to copy the Passover to three or I can paste it here and say.

H

Okay, so this is the agent computer on the master side, so you can see action post is up and it it might, it might tell, by what I mean, is to initiate handshape and fully carnage.

H

So so now the Asian part can connect, have have connected successfully to the master and we can run run a job.

H

Best, this one's a hello world shop.

H

Okay, I, don't know why.

H

But this euro is unexpected.

B

H

Basically, the Asian connect successfully, but the example I cannot run the job.

H

Okay, but let's move on, and so that's it the to demo and the next phase. The plan for next phase is implement cloud API to provision remote in Africa Asia dynamically. So we don't have to start started part we can. We can create as many as many Asian as we won, depending on the workload, and the second thing is implement cloud. Api implementation with hem chart and probably write module. It has documentation and fix some book like the last one. We see and released version two and here the means to the repo the jitter channel.

H
