A

Okay, it's been recorded, nom.

B

Okay, welcome everyone. My name is Martin de su and I'm Jenkins, google Summer of Code organ min or for this year and right now we are at coding phase two evaluation of the program, and today we have three presentations. So before we start, I would like to remind everyone that they can use the guitar a jsoc account too for any questions they have.

B

The the URL should be posted in the invitation and on the Gator channel. So it's under gator that I am /. Jenkins CI, / JSOC seek call in no spaces just.

A

For a second okay, so yeah this is our guitar channel. Thank you, serious jaeseok seek and feel free to join it. If you ask any questions here, we'll make sure to ask them two speakers or just discuss them after the presentations.

B

Okay, thanks for legging, so at this point our students have worked really hard to prepare the code for Phase two and they have prepared presentations to show their progress on the program and we have three presentations today. The first one is a multi branch pipeline support for get lab. The second one is the role strategy, plug-in performance improvements and the third one is going to be remoting /, Apache Kafka with kubernetes features.

B

So I would like to invite the first presenter para J to present his coding phase, 2 presentation, the lead mentors for this plug in our Marquis and Justin, okay, Perry Chi. You have the floor.

C

D

Welcome to the presentation of multi branch pipeline support for gait lab phase two: this is a project which is trying to improve the integration of Jenkins and gate lamp hi. Everyone I am Parature from India I'm, an open source contributor and their devotes enthusiast. My mentors are Michael Jackson, Justin, hanga and Joseph Peterson.

D

So in the first phase, I was working on a great lab server configuration plugin, so I'll just quickly recap through what features that were covered in this plugin. So it's a lightweight plugin and it supports Jenkins configuration as code and it has a separate kit, lab API, plug-in neo Jenkins version, which provides some UI improvements and we, you can also add multiple, get labs server entries with same server URL, and you can also create get lab access token inside Jenkins, which is required to authenticate the get lab API that is used by the plugin.

D

So in this phase, I developed a good lab branch sauce plugin. The main goal of this project was to add these two features, which is multi branch, pipeline jobs and folder organization.

D

So so this completes the convention of three SCM plug-ins in Jenkins, which is kit, lab API, plug-in, get lab plug in and get a plant source plug-in. So these are the functionality that each of the plugins provide.

D

Okay, so the features that include is you can check out over SSL or HTTP remote by giving your SSH private key or your username password, although it's not essentially required in some cases where you have private project, you can provide these external credentials and we have groups and subgroups support. You can choose group projects from your groups and subgroups by giving you the path to that group.

D

We have where book support. This basically allows your jenkins to create a web book in your gait lab server and jenkins listens to a specific URL and it triggers the concerned build based on the event that sent by a third observer. So currently it's a work in progress. The implementation required are kind of done, but there is a bug and it fails to take out the build yeah.

D

So so the next day's pipeline status notifying- and this basically allows jenkins to notify the gait lab server about the status of your pipeline job and we have new SCM trade api's that has been implemented. I'll just talk about it in the next slide and we have worked on reducing the API calls. So the indexing is faster and other functionality as well.

D

Okay, so here is a list of SCM trade api's. You can see if, for example, skip notification that allows your pipeline status not be notified to the gate, lab server and similarly web book mode and check out over search AG discovery. So you can also be it for further extensibility. We can also add additional straight trades by extending this get lab SCM source context, class, okay. So it's demo time so I'm having a good labs, Jenkins instance running here. I will go ahead and create a job and I will choose multi wrench pipeline.

D

Okay in the branch saucers I'll select good lab project yep, so basically the server configuration part that I was talking the developed in the phase. One was this: yeah I am using Jenkins configuration as code and I'm, ensuring the gate lab access token here and the necessary fields that is required to configure in your jet get lab server and your Jenkins so yeah. So it's configured here and I am choosing one of the it labs over and you need to provide your own it so from based on the owner. Here.

D

The list box will be populated with the projects and you can choose one of your project and go ahead and build it. So let's say I choose this one and I'll just go ahead and save it.

D

So right now Jenkins will be indexing. The branches so here the master brand has been indexed and test is not because the merge request has been fired from the test lines. So in this skips and directly goes to the most requests. All the magic stuff is done by SCM API plugin and we have implemented the interfacing in this plugin. Okay, so this so indexing has been done and I'll go to the status. So you can see that master branch the pipeline failed and hear the birds request it passed and will discover and see the result.

D

We can go ahead and see that index index one yeah, so so, basically it builds the pipeline. It checks it out and gives the output so this passed, and we can see that our widget. This is the project where books, integration and initially there was November and I'll just refresh the screed and yeah. So we have a book here that has been created by the plug-in and Jenkins listens to this particular URL and based on that, our, for example, I wish.

D

So here's my Jenkins Jenkins of the console and I'll just put a s, push the event and yeah. So this is the push this on. So basically this is it okay. So this is multi branch pipeline job support and we have another type which is Holden organization, so stay test.

D

So what you can do here is you can build multiple projects in a particular path. Let's say your user name or your group or subgroup. So, for instance, I will show one with the subgroup, so I will provide the path here.

D

There's a form validation here, and it says it said: I let subdue and you go ahead and save it yeah. So it will basically index all the projects did and I have done it already. Here you get the list of your projects and you get the missiles from there yeah so yeah. These are some of the features, but not everything could be covered in one demo, so you can go ahead and try it from our plug-in repository and you can build it from the source.

D

We have a documentation about it and we have also made a alpha release, and so you can install it from the experimental update Center by using one of the new plug-in management food that is also a part of Z sub project. You can just download this binary from the repository and run this particular command, and it gets installing your Jenkins instance, and we can test it out so after testing it out.

D

If you want to see some feedback or if you find some issue, you can just drop your mail at the developer mailing list or you can just file our issue in the Jenkins feeder with github the answers plugin component or you can just come and say hello on our gated Sangha.

D

So so we have some plans for the next plane, so I'll be working on improving the performance of the plugin, which would be revolving around optimizing. The data structures- and there are also some known bugs and old- would be discovered with the testing, so I'll be working on fixing those, and there is also some room for UI improvement, so I'll be working on that as well and implement some of the new features like tag build strategies etcetera.

D

So we have also planned for implementing a great lab blue ocean plugin, which will allow it lab pipeline support. Publisher, okay, thank you.

D

So you may ask me questions if you haven't it.

A

Yeah, thank you for the presentation. Martin is trying to say something, but he is muted. Yeah.

B

I'm unmuted now so thank you. Perry J, for this presentation. I was going to invite people if they have questions at this time. It's time to ask questions. Yeah.

A

I, have a question. Sorry, did you want to know.

E

Please go ahead. Yeah.

A

I want to talk about blows and.

A

So do we have anything in place for implementing this plug-in and what is the current discussion status.

D

So currently, as far as our discussion that happened, the new ocean is building like shifted towards the Fred product, maybe some more improved product. So presently the we are planning to implement a plug-in for that. But there was a discussion related to that that maybe we can directly work on the new interface, which is an alternative to blue ocean. So that's the most further discussion that we had so far. Mm-Hmm.

A

Thank you, I was just wondering, so if you had it to plunk is make sure that it's not a commitment, because yeah there might be able to popsicle stand. It would be really great. If you have it, it might be challenging.

D

Okay, so github and bitbucket has support for that. I look into the codebase and I feel it would be possible to implement it laughs. The blue ocean plugin. Just the thing is whether it is worth it or not. So we need to discuss about that. Thank.

A

You yeah and another question about github organizations and multi branch pipelines. So if you use github, you get a lot of different options in order to define how a meals work, for example, how to discover branches, how to filter them. How to apply admissions and I was wondering whether you have similar engine. Forgive love.

D

Yeah, this is this other function that is provided by the ACM trade api's, so yeah. We have support for that. I'll just go ahead and share with you.

A

Yes, oh yeah, you're, not scrunching right now,.

A

E

A

Basically, you see that all existent the same API thinks like, for example, admission or management, the for Jenkins files, etc. They're supported out-of-the-box for budding. You plugin.

D

Yeah, it did if you asked about the branches and merge request and etc yeah. These configurations are available. Just can you repeat what you asked about the permissions yeah.

A

So in github, by default, github organization, it doesn't allow you to modify Jamie's file unless you have permission to the depository. So the use case is pretty simple. If you have a continuous delivery pipeline, if somebody submits a pull request, you want to make sure that this somebody it doesn't release your product by birth twice and go back, planned and implemented his own one.

A

So yeah by default in my github ranged source. Its enabled I was wondering why they have similar things in foggy cloud.

D

Yeah, so I don't think that we have that particular support for a trusted contributor, but we have sem create a peer that is by default, provided here we have discovered buzz request from fourths. So what you can do is you can just go ahead and nobody you can just select so this. This is one way to do it, but if you are talking about, we can choose some trusted contributors, then yeah, so that implementation, which is done in github branches. We don't have it in this plugin it as of now, okay,.

A

I will check it and we'll make sure to create the jitter ticket today, if it's missing, because it would be really important or jeremy's. Okay, thanks.

A

E

Really quick before we move on I'd like to just say, crotch, a very, very good job. I'm super proud of you. It is a really good job. Excellent work, thanks Mikey.

D

Okay, actually, thanks to the entire Jenkins community for motivation and support, yeah.

A

Thank you doing yeah.

B

Thank you alright. So our next presentation is by AB you day and it is the presentation on remoting over Apache Kafka with no sorry sorry rose strategy, plug-in performance improvements, so the lead mentor is Oleg here. So AB you day, you have the floor and you can start presenting.

C

Hi thanks I'll share my screen.

C

Hi, everyone and okay and I have been working to improve the performance of their own strategy plugin as a part of my google Summer of Code program this year. So what we will discuss today is the performance improvements that have been made to the road strategy plugin and the new folder authorization plugin.

C

Now there have been a lot of performance issues reported through the Royal strategy plug-in and Jenkins JIRA, and so the goal of this project was to improve its performance. Now, we've done a couple of things to improve the performance.

C

The first one is: whenever all strategy plugins got a request to find the permissions, it matched all the regular expressions. Now what we do to increase the speed, we cache the collection of roles that match a given regular expression.

C

The cash gets invalidated whenever a new role is added, and this has provided a significant improvements in the performance of the member of the plugin.

C

Improving the performance in this way is a trade-off between the CPU time and the memory, because we are storing all the pre calculated data inside the memory at runtime now to measure the performance improvements. We were using jamish benchmarks and we from this improvement we have seen improvements of up to three thousand three hundred percent.

C

Now. The other thing we've done is to cache the implying permissions. The Jenkins permission model follows a tree like structure and a permission can be implied by other permissions. So, for example, the permission to read a job is implicitly implied by the administrator permission. So every administrator has the access to read each and every job. That's there in the system.

C

So what role strategy plug-in did was to calculate each of these implying permissions for every permission check. Now we calculate the permissions when the plug-in is loaded, which means when the Java class is loaded and we store them for quick access whenever we need the calculated values now, a challenge we face, there was handling dangerous permissions, so in Jenkins are some permissions are considered dangerous. For example, let's consider the run scripts permission.

C

This permission allowed non-administrator users to run groovy scripts, which could which had the access to Jenkins internals and what allowed them to configure anything that delight roll strategy plug-in supports them as an option for backward compatibility, and this Lord for safety is disabled by default. Now this word can be changed using groovy scripts at runtime, so we needed to take care of that and we added a hook whenever the mood changes and we invalidate the cache entries for these dangerous permissions so and the permissions are then recalculated again now to measure a performance benchmarks.

C

Like I said before we use the JH Bank max. We used the micro benchmarking framework that was created inside Jenkins test harness during the previous phase of G sock. You can see the blog post on Jenkins dot, IO to know more about it and you can implement those benchmarks in your plugins to these benchmark. Reports were generated during the pull request builds and we compared our results to the previous ones using the image visualizer. These results were also verified by running a compute heavy configuration on my machine and running profiling using visual VM.

C

Now the improvements that we have observed after these changes up to ten thousand percent in the overall performance of the plugin, so these are the best-case scenarios, but it has been verified that these performance improvements have actually been made. Now I would like to introduce the new folder authorization plugin. This was a plugin that was created during this phase to avoid the performance issues which thorough strategy plugin had, since this is a black brand-new plugin, it saves us from having backward compatibility from the road strategy.

C

Plugin row strategy plug-in is more than ten years old, so there's a lot and as a new feature or whatever you'd call dangerous. Progressions are not supported anymore, so this them simplifies the design of the plugin.

C

This, just like the road strategy plug-in. This supports global rules and agent roles. The agent roles do not work on regular expressions and we use folder rolls for organizing permissions to projects.

C

Now, let's discuss some features of this plugin global roles, just like what emotionality, plugin and applicable everywhere inside Jenkins, the folder rules work on folders from cloudBees folders plugin and they can be assigned to multiple users and multiple folders. At the same time, the features of folder rules, the major feature folders, is that the permissions granted through a folder well I inherited to all the children. So agent roles, on the other hand, allow configuring permissions for multiple agents and what's connected to Jenkins, and they work on the full names of the agents.

C

Now we also have REST API is for adding and assigning roles, and we have full Jenkins configuration is code support. This is what a sample configuration is called.

C

Hamill configuration looks like, and you can just specify the DEA agent role, folder roles and global rules. Here now, I'll move on to a quick demo of the plugin.

C

This is what the UI looks like right now, so we have a global rolls. We have a folder rolls and we have a agent rolls now. Let me just show you what's going on here: we have an admin role which has permissions for everything. Next, we have a read role, which applies to all the authenticated users. This authenticated user group is provided to us from Jenkins code there's another one just like this, that is the anonymous s ID and that is applicable to all users, whether they logged in or not.

C

Now, I just show you how this works, how to add a folder role.

C

The first thing we have is: we have three folders the root, 1 root, 2 and root 3, and we give the read permission to use a 1 using this role and we have another child folder inside it, and we give you user permissions for configuring. The job I'll add another role here: I'll call it root to read, and this would apply to root, 2 and we'll give the permissions to read the job and to delete it, and we just click Add role and the role was added.

C

Now we have the role here and we can just assign it to let's say, use it too, and.

C

As you can see, the role was added. Also, let's note that user 1 has the permission to delete an agent, that's connected to the master, that's test one, but not the other two. So now, just let now, let's login as user 1 and the only folder he has permission into is route 1 and the folders can be added to the bottom. To increase the permissions.

C

Let's say he has the permission to configure the project and the folder here, but he does not have the permissions to configure job 1 in the same way. Let's just go to the home page and see them see the two nodes which are connected and, as you can see, the user has the permission to delete the agents and but he does not have the permissions to delete. I am test 2.

C

Now, let's just go to user 2 and he has permissions for route 2.

C

Now, let's just go back to the admin user and I'd like to finally show you the configuration it's good working here.

C

This is what a permission. This is what a permissions looks like. This is what a configuration looks like and.

C

Now these are some screenshots from the plug-in and, let's just compare it to the latest release of Royal start lets us compare the performance of this plug-in with that of the Rho strategy, plug-in with all the performance improvements. So let's first talk about global roads, and so what people observed over 500 global rules is that the global rules in the new plug-in are up to nine hundred and thirty four times faster. Then the global rozilla strategy plug-in this is for data set of 500 global rules and folded rules.

C

The in these, the new folder rules are almost 15 times faster, not an equivalent regular x in regular expression, implement stationed in the role strategy. Plugin, you can see the spoil request for the bench back results now. Some challenges that I face that I faced during this phase, the first one was to have official permission checks, and we had a lot of discussion with the mentors when I'm enters to produce an efficient, efficient solution for having permission tricks now as a benefit.

C

The global role checks now happen in constant time that is Big O of 1. Another thing is Java scripts. Json dot stringify from prototype prototype.js from Jenkins code had changed, Ida prototype Jason and it was giving some wrong outputs for whenever I call json stringify on an array.

C

Next thing was configuration discord, so configuration is code, uses data band configurator for data bound constructors, which did not support which neither supported import or export of sense. So I had created to pull request to the configuration discord, plugins and the boots has been released in configuration is called 1.24 now. The next steps would be more performance, improvements in their own strategy, plugin and improving the UI of the foil or authorization plugin, and so and writing user and developer documentation for it and finally, I want auto release for the folder authorization problem.

C

Last, but not the least I would like to thank my great mentors. Whole net runs a and sukoon, and thank you everyone thank you to the entire Jenkins community. uh Please do share your feedback through either the role strategy plug-in, get a chart and or through the Jenkins developer mailing list. Thank you. These are some useful links.

B

Thank you wow. This is a great presentation. I.

B

Would like to open the floor for for for questions I think there was a question on on guitar that was posted yeah.

A

B

So is it possible to set permissions for everything under the folder, but not the folder itself.

C

No, that's not supported right now, if the permission is for the folder or it is applicable to the folder itself and all its children.

B

A

B

Is that is that is that a car is that related to the plug-in itself, or is that the core permission limitation.

C

It's it's both, for example, do you have the read permission to nested folder you'll need the permissions for its parent also, and so we take that a step further here.

F

A

Why I thought about this use keys because sometimes it's really useful for micropenis Asians, because yeah on the folder level, you can define pipeline libraries, you can people find many other folder properties and sometimes, as I'd mean you didn't, want your users to modify these properties. So you want to give people a sandbox with everything pre-configured, so they can create jobs and do whatever they want with these jobs in this setting box.

A

But we still don't want them to modify your folders, so it might be a good use case, but again it's rather Jarecki kit or whatever to think about it for the future I.

C

Take a lot of that.

A

B

It's there other questions.

B

Marquis, do you have questions or astute other students may have questions I do.

E

Not have any questions.

D

I'll, be there I have a question okay, so the role based strategy plug-in and the folder or plugin both are different strategies for authentication right. Sir.

C

So authentication authorization, yeah.

D

Authorization, so what are the fundamental differences between these two plugins.

C

The main difference is row strategy plug-in works on regular expressions which, when they repeatedly called it, has a lot of performance penalty. Because of that and these permissions X are very frequent, so we in the foyer authorization plugin we just straight-up- do not support regular expression that all.

D

Just correct me, if I'm wrong to the functionality of both the plugins same.

C

They both allow users to have different permissions, but the row strategy plugin, can be a bit more flexible. This is designed to give better performance at a cost of reduced flexibility.

D

Okay, thanks yeah, it's awesome project. Thank you. Thank.

B

You, okay, I, think we can move on to the. Is there more questions? So are you making I.

A

Would just want to say a few words, but we have basically a little bit what Marcus said about parochet the question: the project is going really well, basically, we completed the entire jae-seok project, except a few bits like releases but yeah at all strategy, already both big performance improvements. We contributed a generic once tasted framework, which is available for putting developers in the jenkees community, and there are some ongoing adoptions already, which is great and moreover, they will purchase two other projects like Jing his configuration s code.

A

If you take a look at the last release of Jake asked, you may discover that the most of patches have been actually done by a Buddha, but these patches are useful not only for all the growth plug-in, but also for the entire community, because they, the bound configurator, is just the core of liberationist code plug-in and used almost everywhere and I believe that other projects we are presenting today also use this configurator for setting up the instance. So yeah thanks a lot of you. There I think that yeah the project goes well.

A

It was really nice to see this matrix where we have 1,000% ten thousand percent improvements. Yes, sometimes an artificial use cases, but even for user-provided cases, we have performance improvements, something like ten times anymore, which is really great, so I think the goal of the project is fully completed and we go forward by providing different channel EQ. So yeah I mean this is great and thanks a lot for all your work.

C

Thank you thanks. A lot for mentoring me I, believe there is a question in the Gaeta chart. I would love to move some of the stuff Thanks, especially the global road stuff that we've made for folders, but the thing is: if we move the stuff from folder authorization to row strategy, that would mean breaking a lot of backward compatibility. So I think that meant to live together right.

A

Basically, we had some discussions about making our all strategy plug-in pluggable so having additional selection strategies, not on delegates but, for example, folder, selective and something else. As an extension point, it might be one of our natural involvements for the project. You just can just combine these plugins potentially, but here right now, it's not available.

B

B

Are we ready to move on to presentation? Well, thank you very much. This is great, so I think we're ready to move on the presentation. Number three and presentation: number three is remoting over Apache Kafka with kubernetes features and our student is long and lead mentor is Andrea Falco, but today, on the call we have butuan, who is mint, who is helping with mentoring this year route? 1 is a former JSOC student who's now mentoring this year.

B

So long you have the floor, and I would just like to say that oleg, if you can take over for a couple of minutes, I'll be right back.

F

F

So today, I'd like to present about the phase 2 of my project remotely over opposite, have Karen at the future and before we begin so I'd like to reintroduce myself long I'm from a university in Vietnam and for other project, my mentor and Roy and Kate Bhutan Suppan and oh yeah, also he's the technical advisor and sub-project.

F

So the current version of promoting to have care requires users to manually configure the entire system, which had many moving parts, a zookeeper and Kafka, and he also does support dynamic agent provisioning. So it's hot it's hard. Okay, it has to skill and for this project we aim to solve two problems.

F

The first one is an out-of-the-box solution to provision a budget Afghan cluster, and this is what I have done in the first one, and the second thing is dynamic agent provisioning in kubernetes, and this is what I have been doing in Phase, two: okay, let's move on. So, let's take a look at the last phase work so for first one I have implemented a community factory adapter class, so this class can be used to connect to kubernetes cluster.

F

Always different kind of Korean show light secret, fried squid type when maybe five or six type of credential, and the second feature is large in Apache Kafka, a zookeeper in craft in kubernetes, with one button, click and also ahem short to bootstrap the whole system and in the beginning of phase two I have also released the 2.0 and far and publish a blog post, and this is a screenshot from the launching Kafka in kubernetes feature.

F

So user can put in the kubernetes cluster connection information here and then just click, the stuff, Kafka and kubernetes button and wait a few moment and everything will be set and done. They don't have to figure out how to configure Kafka and okay. Let me move on to phase two. So what I have done in phase two is I have implemented a cloud API for automatic agent of ending in kubernetes and also support. Jenkins configuration s code and I have implement an integrate.

F

The future ways to the ham chart and released the beta version, so every one can check out the new plugin in the experimental edition okay. So this is a diagram of the cloud implementation.

F

So when you will need to start the job and and I Jenkins.

F

Like junkies is, there is no note with the corresponding label is presented contains. We asked the cloud to provision a new node and this Kafka community cloud with provision. A new new node, which is early, have clouds left and Kafka Crosley will launch chaff computer launcher with an instance of a Kafka cloud.

F

Computer traffic, alchemy tarantula is a launcher from version one, but I have extended it so that if the computer is receive an instance of Kafka kilometer, besides launching besides reinsurance left, we also use kubernetes api to launch a part on the kubernetes cluster and okay.

F

Let's move on to the demo phrase.

F

So you know I have a squid from first one, the demo squid okay, so for this demo, I wish I will used a hand, shot to launch the whole system by running Remy, stole the chart and then ping well for Jenkins and after Jenkins yup we copy the password to clipboard, so I don't have to find it in the kubernetes to quit and then open the main leader brother.

F

Well, this hand shot is based on Jenkins, Henshaw and Kafka Henshaw and.

F

You can duplicate it out his church, the stage' so so, which just Hemi stole.

F

Her mean stall, which have a zookeeper and Jenkins most Wendy and Jenkins may take about three minutes to download the plugin and metadata and initialized.

F

Okay, so my connection is unstable, so I have a script to automatically open Google when, whenever they take, my connection is slow.

F

Okay, waiting for the junkies part, then kiss is initialization. Let see the lock okay, Oh.

F

Another hour my hand shot is based on Jenkins in stable repository and Kafka in incubator, repository and I also have some ham short fellows for the limo sham conversion and I use the experiment to a patient to install the beta version of the plug-in, also in so job yes, er plug-in to initiate a job.

F

Okay, okay, chunking is if up and I will look in into Jenkins in the ham. Short value of I saw the value face like a parameter of configuration file for the Hampshire and in this I define as a CSV a config. So basically, this tray CSV will will conflict. The remoting have kept looking and also conflict a job to test test. The asian.

F

F

So, by using ham shot with trey searcy, I have pre-configured everything before launching jenkins zookeeper URL URL, and this is the cloud and it has. This is the.

F

The kubernetes connection info, we have kubernetes api server, URL and namespace.

F

Okay, success jenkins new oil, so this is the basically the asian information description, working directory and label. So the label I said here is cloud, and this is a demo job. The job is a simple one. So with your one on the Lee Clow label, so label cloud is served by no node and one cloud. So this it means I didn't mean when only the job which caused a left cloud cloud API and it's a simple public, echo hello world.

F

Let's try me on the job and when will when will when you start this job, you look for a node with a label cloud and if there is no node presented, we will look for a cloud which is our club and as a club to a provision once patient, and this is it position one agent.

F

The agent name is based on the clown and a random string.

F

So when capital unsure launched the comp code, the large function, it will also, you cannot hit API to.

F

I should cut inside the committee cluster, so this is a Asian part. It also had the same name as the Asian on the master side.

F

Let's place a description.

F

So yeah, this is your argument. It is same as here and it's image from the official image from Jenkins slash remote in Africa region.

F

Okay, so the part the asian is online and it will automatically run the job.

F

So when we run a job, so we ran a job for the first time on a new agent. It will take a while because argentine master need to transfer all the Java files and the classics to the Asian. Ok, it won a bash squid. We should echo hello war and it also take a while to finalize the job, but this is just for the first one after the first one. It will be fast because all the job and the crusties are presented on the asian machine.

F

So one thing I I don't like about the car and I believe because is too spammy right is spam or block yeah and that's what they all eyes will improve in the next face. Ok, so the jobs are fast and.

F

We have, we already have a slave here. You can try to run again.

F

Southern, so the second one only take 3 second and waste plow API we can, we can scale, we can scale the job like whenever you don't have been up, not as cloudy I will create an agent and then create important communities, and then we can still as much as a community cluster can handle, and this is a nice hinge in your technology, in clarity and and after enslave it created. It will stay here forever and you don't have either manually.

A

You know some audio issues.

B

Same here we have audio issues.

G

F

Can you hear me now? Yes, hello, ok, yeah, ok,.

F

And you don't have to either many only are.

F

Like element in phase 3 is not champion automatically communication after I mean so now we they manually and when we terminate the agent the part it also.

F

B

C

B

C

B

Audio issues are still ongoing.

B

Okay, we see the next slide. Try to continue. Please.

F

Okay, so one challenging challenge one protocol I face is the version in the blocking palm fire is 1.71 25, so I couldn't be the version of some dependencies on my plucky like chapter 2 part 3 or the nuke community, Java client lip library, because the new dependencies used as a refuge, a 1.71 district and.

F

This is and I, don't know how to service this, because Alessa is at. We cannot appear the looking form 21.7 426 continued conflict with the over Jenkins core.

A

Yeah we we can actually solve it. It's not a big deal to solve it for plugin poem. The problem is for your plugin, because you need the recent Genki sweet aversion to pick up other cheeks, so we have reduced you patch in Jenkins code in the latest victor. So basically, if you wanted to include this patch for the mountain Kafka, you would have had to bump up the dependency.

F

Yeah: okay, thank.

A

You it's possible, but yeah, so we're gonna plug in poem. Let's take it offline that are ways to work it around example. The most simple way is supplying national as well 4G as a property, so that you can overwrite this property in your plugin and that's it. It will work yeah.

F

That's awesome, Cory solution, okay, so that's a big'un. We may try to do in phase 3 and the next phase. A phase 3 plan is okay. So now we have to point to the 2.0 beta version and most features are implemented and we just need some more unit tests to officially released 2.0 version, and the second thing here we test the retention strategy.

F

It's something I said earlier that the patient we stay forever after created and retention strategy is that user can choose so that Asian can terminate immediately after running a job or it may wait for a timeout before terminating so like like the Asian. The number of Asian can scale up and scale down automatically, and that is something I'd like to do and.

F

So for now there are many new things and there isn't any documentation and I wanted to arrive more documentation and Quick Start Guide, so that new user can get used to outlook in and the next thing is integration test, a cache can kubernetes. So the blue key now have many moving parts and- and it would be nice to have an intervention integration test with author or the modulite traffic and kubernetes, and the links and friendly Q&A.

B

So I think there's some questions. Yes, thank you I'll. Let you answer them.

F

Is that any type of cumin are BAC associated, which is not one of the so yeah? That's why community are BAC is part of the hem short so.

F

F

Okay, I will show the screen again.

F

Okay, so the hem chart for remoting kafka agent is a very simple one. It's mostly mostly juice the the power of the Jenkins Hampshire and Kafka hand shot just reconfigure, some small value and uh that look at the junkies hand shot. So this is the official Jenkins time chart and it has already have all the RBI CS service account for Argentine master roll and roll binding. So the roll solo for the RBI zero for the champion shot is only involved. The pot yeah listen create, so that's it.

F

The answer is, are BAC is interpreted in the interdependencies and sure. Thank you for not. Oh and now. The second question from monkey is Mike. I noticed you're caught in defining a note part in a note URL. It is configurable with an infrared controller. Okay. So this we can also contribute this by overriding web overriding Jenkins ham, shark configuration. So look at the default value again. So.

F

So barda for champagnes heritage is a load balancer to expose the service, but as use mini, coop and I. Don't have load balancer, so I have to change the service tire to note part. So, okay,.

E

That make that makes total sense that ain't.

F

Your operation, that's it and question from Justin. Are you incorporating your changes into the mention kiss him short or was it me a separate hand? Short? Okay, so I think there will be a separate hand short. So this is just a use case of the official our chart so I, mostly juice, gym, kids, I'm, trying to kafka headshot and over while that's some small, otherwise you can see is pretty long, but because they say for demo, purpose is a actual hand shot. We are only.

F

It will remove most of this, so just the mini more over YT setting father to install the plugin and configure it so judo can try out so the file. The answer would be. That will be a separate hand truck, and do you have any more questions actually.

B

I have a question the code you're showing there in the llamo. It's not related to your plug-in, but it's these yellow files that you are showing what I'm not familiar with what they are like.

F

Can you okay, so this is the physical health. Our values and have value is another word for heme short configuration and basically, in one hand, shot. Okay here is a official Henshaw and it defined many configuration yeah and now I am a user of this hand. Short and I can override any configuration here and this first project teams, the is for the dependencies, and this is the configuration I over Y, so I hope I. The the version contains version I over why the blocking install the case est justice. So this is a choker.

B

This sound is cutting off.

B

Okay, we cannot hear you long.

F

I'm shot value is I'm short configurations.

F

And now we can override, we can override setting, is a Burnham shot and in this ready to try it for my hand, shot.

F

So for the photograph can Han shot I just alrigh a small setting so that it only running.

B

Not really the quality of the sound is it's cutting off, but I think at the high level. I understand your answer. So so yes, you've answered my question. Thank you.

F

B

F

B

Do we have? Is there other questions or comments.

A

For deployments so, basically, once you have found chart in the repository, it's relatively easy to deploy it to local chat energy instances, but have some automation put it.

F

Museum, so it is okay, so yeah I'm, my hapless quit so user and he stole the hemorrhoid enhancer Museum for now, I only plan to host the hem shot in the github repository, but it would be nice if you can can copy the head shot into the air one with motive to me.

A

Well, basically, there is a lot of machinery around that, so once you get it integrated, github master branch I reckon cause. It becomes relatively simple, so yeah there might be few scripts of the subject for the discussions.

A

Okay, thank you.

F

Thank you. That's what I'm saying everyone for listening. So if you have any question, please don't hesitate to ask.

B

Very well, thank you very much long for for this and.

B

Butuan, did you want to say something yeah.

G

Okay, so attend you, no longer a good job. For the second phase, we managed to deliver. I want a great feature on town with his faith and so I did. We did to release and find it. The second phase there are so long, but I fixed some bucks. It's a box sitting plugin, so I appreciate that so yeah. We looking forward to working with long for the test phase full of equipment and hope that we can release.

G

Thank you. Thank you. So much.

B

Okay, this is this is great, so I would like to congratulate all the students for the work that you have done so far and wishing you the best for coding, phase three and I want to thank all the mentors for supporting our students. So thank you very much and I believe this concludes our presentations today.

B

So thank you for watching and see you online. Everybody yeah.

A

Just some beats tomorrow we have a second part of presentations for presentations by five students. So tomorrow, would you not on digital history stock? We will have people from outreach union, so we have another project going on right now and yeah. They will be also one student journey from another agency or organization to present to work about Jenkins, so we have at the same time for presentations.

A

If you have any questions. Meanwhile, just the comment in a guitar shot and we can't ask all students to what links to their presentations in the abstract document. We have said in the meeting notes.

D

Oh I just wanted to add something. Is that okay delete.

C

Dml project.

D

Okay, so you asked me about the blue ocean plug-in okay, so the present plan for Jenkins is like they want to. There is no concrete plan as of now, but there is a plan to modernize Jenkins, so blue ocean would be improvised, and so my plan was to implement the gait lab plug-in in blue ocean, so that I learn about the architecture of blue ocean and and I can contribute to the modernization of I mean the blue ocean plugin. So so that was my plan right now.

D

A

So I believe for this topic will be heavily discussed. The DevOps voltage angles fault, so they will be considerable summit on August 12 and most like the web, UIs and web. The organization will be on the agenda for these discussions. So what's the tune to see what would be the final outcome of these discussions and yet thanks a lot for your interest in this area.
