Hi in this recording I'm going to show you how you can use the cam command. That is part of the openshift githubs product. You can use the cli to bootstrap your githubs pipelines, environments, so the cam command. There's one feature I would like to show you before I get started with the bootstrap. Is the complete shell completion?

A

If you type uh cam completion and then show you the command you can use you can you can plug in an issue? But in this case my shell is a bash.

A

So if I do this here- and I can then do just tap to complete my command, um if I do put v8 the oot tab and then I can also do like the options, I can do that and then show me all the options.

A

Yes pretty cool, so um the bootstrap command here cam, I'm going to show you how to bootstrap uh using the interactive mode and and like uh I can also uh override any of the default um here um before I get into the interactive mode, and then it will ask you for those questions in this case, I'm going to use the push to git option. What it does is, it automatically creates a github repository for you, and the requirement is is that the gui possibly cannot exist before you want to come in. So there you go.

A

So, as you see it done, some checking that passes all the dependency checks.

A

um When you start the githubs operate, when you create a githubs operator, it create the fork aqua city instance in the open shift dash github's namespace. This will detects it and uses this just uses that instance. So now I'm going to accept all the default.

A

um Then I only get to answer two questions. One is the my.

A

Githubs repository url: this is where all the resources the generated resources will get pushed to again. When you do push to get your repository should not exist, and you also have to set up your ssh key on the um destination git git provider. Github in your account, um let's see, I need to put give it that name and then the next question is um well. What is the repository for my application?

A

The bootstrap command will allow. Basically let you to bootstrap your first application when you're done with bootstrapping, you get the uh configuration and then you will see when I do, the um apply will will launch. You will create some algo cd application and the august application will basically is just keeping track and syncing up your the configuration in your git ops and make sure it's up to date and deploy your application to the cluster. So this is going to be the your service or application git repo.

A

So in here I have a.

A

uh I have a taxi app.

A

Okay, booms go off and, and did all those and and then it just generate the um the yaml files. The resources by default is in this subfolder of your working directory under the name of your uh your get your get the get off the repo name. So in this case it's going to be.

A

Githubs- and these are the generated.

A

Configuration or resources now so let's go to take a look at my repo.

A

So you see it created a private repo and puts all the resources here and in this demo I'm going to make it a public repo so that I don't have to set my ssh key in the argo cd repository.

A

So I'll make this.

A

A

Okay, now, if I go to the ago city console log in there, you don't see any app, so I have to to do this following step. I have to do oc apply.

A

I want to make sure we can see what the type minus k and I'm sitting in the generator folder. um So it's going to be the config algo cd so that create a few taco cd applications.

A

So when it's almost done so when it when these are all done, you you can see my taxi app is deployed on the cluster.

A

So this cicd app is making sure my um my git ops. Resources are in sync and what is indicate is uh is is in sync on a cluster.

A

um Let me go, and so, if I go to take a look at my my text, app is deployed in the um in the dav namespace it there. You go it's up here and I can hit it hit the url and then it's just a demo um uh image that the demo uh on nginx image so yeah. That's it that's! uh This is a quick demo to show you how you can get perspective and get your first application on the githubs.
