From YouTube: [Online Meetup] decK Demo & Open Forum

Description

Kong engineer Harry Bagdi demos decK, a tool to manage Kong's configuration in a distributed manner. After, we'll facilitate an open forum for community members to discuss their projects, Q&A with Kong engineers, and more.

Join our next Online Meetup: https://konghq.com/online-meetups/

A

Okay, great so welcome back to our community call. We did this the first Tuesday of every month, just a quick reminder, while today's call will be a little bit more casual with more room for open forum, if you're ever interested in presenting what you're doing was kong or a plugin, you wrote or personal side project related to our community or con reach out to kevin or myself, where first name last name at kong, HQ, calm and we'd love to get you set up.

A

It's it's really fun to share what everyone's doing and it would be an honor to have you on the call so exciting news today, we're now over some introductions, which you just did. Thank you we'll talk a little bit about con 1.2 harry is going to demo his side-project deck and then we'll leave room for open agenda where everyone can talk about their project side projects.

A

If you have any questions or comments and ears or community managers where we're on the call got anything that comes up it'll, be more like a causal roundtable discussion than anything, particularly structured.

A

So as as everyone will be hearing about soon, all over the internet channels, con 1.2 is released today. So congratulations to our team pushing that out great news and last community called tebow, went through and did a demo of what was coming out in 1.2, as well as a preview of 1.3 that recordings online on our community call page. So you're welcome to review that as well.

A

Alright and then I'm gonna stop sharing and I'm gonna hand this over to Harry for its introduction on deck awesome.

B

B

C

So that is a it's a you started as like something to solve a problem on a something like a site problem that I faced when I was working at sa ps2 comm. We had this con configuration problem. Well, you know we wanted to declare it in the configure, call and call me smack my database, and only recently we have started supporting DB less mode where you know you can put in all the common tradition in a file and then Kong can start up without a database.

C

So yes, I'm, ready to take this. It's a it's a small go thing. Deck is also something that bats are interested to know today, it's quite powerful by itself and has has a certain set of features and then.

D

C

To solve really the configuration problem and how to how to you know export configuration import it back. You know if they extinct it reset it. You know. So here's our going through the feature set a real quick. You know you can export all the configuration that's inside counts. You know, eat your routes, services upstream certificates, whatever consumer should have anything you can export it out.

C

You can import that back into come, and so that's like a basic feature set that any you know, declare the configuration to needs and from that that's where, like differencing capabilities, are more like really the most important features in this project. Where you know you can make some change in the config file and then see and keep the config file is the source of truth and then figure out. Okay, what's different between the config file and in the database right.

C

So you can see that and also, if somebody changes and goes I hadn't changes the database you can make, we can figure out using the functionality of tape if something changed which was not supposed to change. There are some recent features that were that have been released and they can last month or so where he allowed me to declaratively, configure comp or the different teams. You know so, if you're working in the connector bias environment and you have like different set of teams, each team would like to manage their own configuration and they collapse.

C

You could do that so yeah, that's like I think that enough talk- and you know it's really hard to wrap around okay. What is how are you talking about really here so I'm just going to go to the tabular and then just start showing you? What actually it is so can you guys see my terminal awesome, so we have like a two-phase demo here. So, let's see so deck is installed.

C

Dec version, 0.4 0.4 was released yesterday by me. It adds in support for Kong 1.2 right, so neck is compatible with 1.0 at 1 and 1.2 after 1 or 0. We have this compact promise, so it's easier to maintain neck for these versions. Yeah.

C

So just printing neg help will came out a little bit of overdose output yeah. So here's our the available commands that we are talking about right. So basically, first you would like to do like you know, obtain to verify connectivity with comm. You can use dec dump to export configuration safe to synch it back. You can also reset the configuration anything different, so we are going to go over these step-by-step, so I have account 1.2 cluster running. So if you do big thing you can you can connect to a composter.

C

They also supports things. You know like authorization and authentication. So if you are using, you know one of the earth clock ins in front of Kong's admin- API you can configure take to you- know, supply the API key or basic or credentials, but if you're using Kong Enterprise there are birth, details in tokens can be specified using mix. So that case takes care of those things. So right now, I have a empty Kong cluster, but I'll still go ahead and do a daiquiri set.

C

What it does basically is something similar to Kong's migration preset, so it will wipe out the entire all the entities you know, which includes consumers, route services, plugins up streams. You know everything will be just cleared out. Next, we have a ml file, which is our source of truth right. This is what we want our configuration to look like. So what like? What is declarative configuration essentially? Is you want to specify what the configuration should be? We don't know how to get that right. There might be. Some service is already in khong.

C

There might not be some services in comm anything like that, but what you want ready to do is give this this file to comm. Tell it. Ok, I want the service name service, one which proxies to mock window at all. It should have a basic hall plug-in enabled on top of it, and this is the configuration of basic auth.

C

We have a route associated with that service route basically means you know, request would come to calm, and these number out properties it would be matched in the forward rate in the proxy right, which is a which is so here we have a route which is nearly quest that starts with slash or one should go to this upstream Mach minute all right, and then we also have another plug-in, which is at the global level you can see. There are, there are different indentations in the sea, and so this plug-in is the Prometheus.

C

Let's say we are running Kong inside you know Cuban, Reddy's, environment or anything that is, you know, Prometheus monitoring available. You would like to run the the problem is working for each request. That is proxy Viacom. Alright, so we have this configuration, so I am going to do a tech div right and usually you supply this state fight right. We could be refer to this as a state file and I defend, and it tells me what it would do to get to the declarative configure right.

C

So it says if we will create it, will create a service or this one service to it will create a route. We create a global plug-in which the committee s we will plug in and it could create a basic auth plug-in once over. We service one right. So let's say we sink this out right, so we do a next thing and all these services and droughts and everything are created. So let's go ahead and eat conch running on 8000 won, I will go ahead and look up.

C

We can see that we have to service the same right. We have service one and we have service too right. So.

B

Let's go answer.

C

Which one route- and we do have a route running here right so all good. We have got everything set up right now. There are two features right now. Let's say you check this file into your gate repository and you want to change it. So what you do is. Okay, maybe you want to start accepting HTTP protocol on this, so you add that here you know, maybe you want basic auth plugin. We actually be enabled right that was enabled to false means, found good, actually not run it right.

C

Let's see that to true, and we also run. We want to run this on HTTP board right. So now, let's see yeah, we do a negative right, so what configuration is changed so now what they go does is it grows compassion of configuration that is inside Kong's database and the configuration that you have specified with Kongo TM. So here we can see that we have specified that you know enabled was true change from false to true.

C

We added the protocol HTTP a to this earth plug-in and we are accepting this HTTP protocol inside the route right. Let's go ahead and sync it up, and if we are do again there, it won't say anything right. So now, if I go and look at plugins, we will see that the basic auth plug-in will be running on HTTP any HTTP, and it is actually enabled right. So so it can. We can go ahead and figure out. Okay, what changed? What did not change? Another important reverse thing is another important feature that we support is.

C

Let's say we create a full service right in calm.

B

C

Say calm, so we created the service, but we have not added it to work on the amyloid rate, which is a source of truth. So now, if you do a take diff, it will tell you that dick would delete this service because it does not know about this at all. So if we go ahead and do a tech sink and then do services, you will say that it is not found right. So once you do next think- and you do take, this Nick will just completely eliminate what delete whatever you have.

C

So this allows for, like you, know, declarative a token calm and using yet operation. So maybe you have like you know a github repository tracking this configuration and you push changes to it and then you know you have like a CI job which actually configures your comp in different environments and so on. So that allows you for make a pretty simple config management style of things right next I have something up is like we taking this. You know open noise generator. So what I'm going to do is again reset my configuration.

C

It's let's pause here for a second any question.

C

Okay, no questions, that's good! So let so we are going to do a little bit of distributed. Config management, where you know. Let's say you have like a few different teams in your enterprise and you would like to manage configuration across all those teams. So your solution is, you know, maybe ask each of the team to send a like a PR. You know to a common github repository which works, but sometimes what we want is you know if you have like a micro service based organization, you would want to.

C

You know, have config management also in a distributed manner, where one thing can manage its own configuration income and it does not it party right. So here you having to do something called select tags inside Nick right, so what they tax is a feature that will come 1.1 which allows you to adding more metadata around your services or out anything any community, so you can have or no key value pairs or you could have like just basic configuration. This team owns this know if the service breaks or what should happen. No.

C

This is like a gold level consume or silver. So, basically, any kind of metadata that you would want to add. You can add music tanks and that's what we are using right. So here we have selected tags in index, which means they will manage only entities which are tagged with these two values. Right, it says manage to my take just so that anybody who is looking at that service can know.

C

Okay, this is managed by deque, and this the service below everything in this file belongs to team zero like ending zero can be you know as a front-end team, or you know your American team whatever, and then we have a team 42, which is exactly like a very similar file, some tweaks and and that in that we say okay, this is seven figures also manage my team, my dick and but 1342 is responsible for this. So now what you can do is you?

C

Can you can do a div or you 0, a camera, and it will say it will create those files. So, let's.

B

Now think this so.

C

You think this huh now, let's do our dip of team 42.7. It will sink that. huh Let's think that now, if you do a deck dip or team zero, you get nothing but it but team, zero and T 4 T 2 can be different, git repositories right at this point. You do not need to actually worry about anything. No team zero can make changes to its git repository. You know configuration without having to worry about team for it. It's not even aware that there is a team 40.

C

So if I do a div, it can correctly check that sync that right, if team 42 goes on and creates OD something teen, zero doesn't need to do anything. So it's like completely separate to separate entities. You can also do something called neck down and then it would create something called common rocky amel, which has all the routes and services and all configuration that belongs to move the pins. So you can see here we have t0 and we also have.

C

T 1 T 2, so we have services and routes 1442 versa, so it allows you for a distributed management of configuration.

B

C

That's about it, you can export configuration import configuration. You can sync your configuration to Kong, you can affect to Kong if you make any manual changes inside conch and do not make those updates inside your EML files make we detect those as well. So it's like one single source of truth for you yeah, and this was also something that is powering our interest controller. That's what it uses in behind the curve touch through. You know detectives, and you know sync whatever keyword and things we have to calm yeah. That's all that I can cool.

A

Any questions or comments or thoughts from the community.

D

Are you hi, I'm, good good, great? Thank you. Are you I'm doing good I'm doing yeah, so I have a question on this sink and like so. What I was are thinking about is like when you said they give someone do the configuration in Indian dashboard and we do DIF from the broken. So it detects that there's a difference from the from what we have in local file and is indeed in the cloud or in the dashboard, so that deck will be able to take those changes in the existing file over how to work.

D

So is there any way like, if suppose, due to some production issue, we did some mineral confrontation index board and now we want to keep it as a part of file as well, so how we can do it over yeah.

C

So you can do that automatically as well. So what you would do is basically make those changes. Manual, changes inside calm and then run. Make them right or take dumps will basically export all of your existing click. The current changes you have inside comp and put that into your yeah Mel file right and then you can get those reviewed or keep that as a source of truth.

C

So initially what you can do is you can set up calm manually or you know, they're having pollution issues, change those manually and then do I, take them and then put that into a file. So it serves as a backup or post, and it is a source of to test line. So.

D

We can then, in future we can use that file is a source of truth and for the changes to put it right. Yes,.

E

Good, thank you. So these sounds were to think this controller also Harry.

C

Could you elaborate, what do you mean exactly like.

E

Right now, whatever you showed is D business with BB. Oh.

C

Thank you. Sport was married for the database world right, the DB less world in the DB, less wordy calm already has a figuration right, so you would specify a config file and that config file would be loaded by Kong in the DB. Let's move, and so you don't need to actually manage the configuration at all. Your config file would be the source of truth. The format of next concur with that next config file and Kong's config file is same right.

C

You need to add one format: version property inside the amplifier, I showed you and you can supply that to the DB, less common mode and everything will go fine right. So we're compact with Nick is compatible the conchs configuration format. This primarily is for the database world, where you know you want to Biff things and you keep things in sync together.

E

B

That answer your question.

C

E

A

This unit, maintaining.

E

The boring, the own ingress resources.

D

E

If you want, if you want to pull the entire information EML format, then we can use, they can pollute, he's dead.

E

Okay, okay, then not a problem, then we'll again one more time, we'll read through the documents and then we can post it.

C

Okay, yeah yeah post on combination, but if you are using the English controller to configure Kong, you can configure it using keep configuring using that it uses take behind the scenes. But if you want to configure at once and then pull all the configuration out using take that's also possible. Okay,.

A

Any other questions comments.

A

Nope, okay, well Harry I'm sharing, so I could take the screen back.

A

Okay, so we are in our open agenda portion now: I'd love to hear from the community what projects you're working on, how you're using Kahn. If you have any questions anything burning on your mind, just want to check in.

A

Anyone want to go first, I'll start calling on people.

A

Your first time on the collar, how are you using and what's what's really exciting to you about about your project.

D

You're asking me light yep, okay, so this is out usually for me. It's like a week. Please start calm, so I'm started learning about it and right now there is nothing from my side to share with you so how to start, but I will first learn it and then maybe you can share further with you guys great.

A

Sounds good yeah.

A

Anyone else about Gaston are used in a place where you can can chat. Gaston.

C

Ungodly ungodly.

A

Environment, okay and I'll give you a pass daniel. Has it how's it going for you anything exciting in your world yeah.

F

We're learning every day with Kong, so we were dealing with projects with our customers. Talking about the new technology. We are more deeply into more yeah integration project, so Kong and in the context of the kubernetes, is something new for our customers. So we develop the whole ongoing about the topic and that's quite interesting to see the evolution of the product and the evolving of the community. So it's quite good.

A

And for the new folks Daniel, do you mind sharing a little bit about about what your company does or how your team, what your team's building.

F

Yeah we we are solution, service provider in Germany, would encode centric and Co centric offers different services. This integration part is one of it and we normally do yeah individual software developments, everything the customer needs and eat, and that's why we choose Kong to bring it also to our to my colleagues and say you don't have to build it on yourself. Just take this use it within the custom projects and see what goes on with it. So we on the track, yeah.

A

F

A

Is there anything you've built recently that you're either excited about or proud of, yeah.

F

We all were proud of being part of the cantata, collective and Barcelona ourselves. What soon so, some good feelings getting to know each other I missed you directly at the Kong collective I, only heard from Michael that who were and also in Barcelona so yeah.

A

I was there for coop con, so I was I. Was there at the show on Thursday and Friday Friday I took a pass on mark.

A

I'm glad he had a great time with a partner, collective I know. Our team did as well they're they're, pretty blown away by how everyone showed up.

F

So this was one of the things Jeff couldn't mine, don't think about it. Absolutely.

A

Anyone else want to share what they're doing or do you'd like any questions at all for any of the Kong engineers that are on the call, if not we'll, wrap up early. No.

F

I mean I I, just kind of want to share that we're doing more more events around the world. This clean blood work doing two meetups in China. One in making a one in Shanghai I will be a cute clutch kind of friendless.

A

F

Have another one to Lisbon: we have another one in Korea or Japan, so we're gonna try and bring calm.

A

F

Our open source engagements around the world so.

E

You know if you have a meet-up.

F

You want us to participate, our you just want us to bend in the city and collaborate with us to create an event. You know we love to talking to each out to me: iteven, dot, genic and.

A

Kind of to piggyback on that, if you're excited about what you're doing with Kong and want to share that in the meetup format, we're happy to support you both through promotional stuff, a little bit for infrastructure and and can help make that happen. Yeah.

B

Uh-Huh I realized that that there is no meetup in Brazil and and in San Paulo, which is the biggest city and I was thinking about starting one.

B

If there is anything you can have have help I would it would be nice and cordial grudges here, I think about talking to to him? Maybe she can. He can speak absolutely.

A

Yeah great I have your email I'll, send you an email right after this okay.

B

Thank you very much. Yeah.

A

And I wonder speaking of Brazil as Hossam on this call by any chance it says.

E

Panicky news: oh.

B

A

A rage that out to live on our website of eternity happy birthday has Sean yeah.

C

Yeah just to wrap it, one thing I think for those people who joined in a little e-pawn, one dot is coming out today. I think one or two is shipping with a lot of really cool features. You know support for a wild card as an eyes where you can. If you have, the girl starts like a white card certificate Congress on that on white car domains. Previously you had to configure each and every domain you can now computer come to send. You know 302 o3o like HTTP redirect.

C

So if you want to accept traffic only for each Pony HTTP protocol, that's possible. You can also the lot of performance enhancing stuff. So no given function enables the router it is backed by asynchronously. There's a lot of DNS improvements. Where you know warm-up can happen, ready, cool new features. Is we have two new open-source plugins, so proxy? Caching, which is you know if you want to cache responses from your extreme services? It was an enterprise feature previously and now it's it.

C

We have open sourced it with 1.2, so you can use that back it with three days or a bucket of comics database and so cache traffic to speed up your API is, and then we have also. We have a request transformer plug-in inside in the price, which was a little more feature part, but in the open source one we have more close together, introduce that as well so and then there are a number of performance enhancing improvements in 1.2 so do check it out.

C

The releases think the most like what is in the process and yeah check out without comment, just check out the change log and looking for getting you guys, yeah.

A

Thanks Sarah, if you're going over that, and so is there a question I.

E

Know one cousin one cushion from him me like: we are trying to set up this distributed environment, so I heard Daniel from code centric. We may require some help or some need or discussion. So can let us know what is the best way to reach to you. The code center team, the.

F

Best way to reach me is well via males. When already has my mail address, so just contact them, and so he will forward my email address you but I'm, also in contact with some of you saw me already so there's already conversation about with you or with your company. Ok, we'd submit this.

E

F

E

Ok then it's open then we'll be in continuity. Thanks a lot welcome.

A

Thanks guys cool, so my last thing to plug here is consummate and we are having consummate 2019 and October October. Second and third here in San Francisco this year, we're focusing on building the next era of software. So API is micro services and mesh for the hybrid world.

A

We currently have our call for speakers still open, so some of you might have caught up, meaning the call that Dennis Kelly, who is now a con employee, was speaking at consonant last year, so that could be used someday if you'd like, and we're also looking to nominate women in tech to speak at our conference.

A

Currently we're doing a promotion to nominate strong female leaders in our community on social media. So keep your eye out for that and if you're a con champion or are interested in becoming a con champion. We'll have some very special events for you as well at consummate and thank you so I'll be posting. This recording and some notes to our community call page on the website. Later today, or tomorrow and cognition, our forum is discussed, Kong HQ comm, it's a great place to ask question and our next will be July 9th.

A

If you'd like to participate in this call by you know showing a demo or even just talking a little bit about what you're doing.

B
