Hello, everyone I'm doing a few videos on development with IDE on a local openshift cluster by local, open chef, cluster I mean using open shift container development kit or in short cdk and by IDE I mean you can use any any idea of your choice. But these videos will focus on using JBoss developer studio, which is built with toolset.

A

That is required to interact with all recently Red Hat as released JBoss development, suite, which is a combination of open shift cdk with the continued development kit, as well as the JBoss developer studio, which is the IDE. These two come together in the devas development suite. So when you install this, you get a completely integrated environment where it's easy to do the application development using IDE, but before we get into how to use, let's go through a quick understanding of how this all works.

A

So you have your local workstation, you'll, go and download the CDK in our case, we'll do JBoss development suite, but that includes cdk right so download the cdk first, and in order to download that cdk and use it, you need to register with developers, dot, redhead calm and once you register, you will need those credentials that you used to register to set up the openshift cdk. So that's the first step next, once the cdk is downloaded, you start the cdk on your local workstation. The CDK will start up a new virtual machine.

A

It uses virtual box by default, but you can also use, for example, if your workstation is a Mac, you can use X hive or VMware fusion or, if you're running on Windows, you can change it to hyper-v. If you wanted to run the VM with hyper-v or on Linux, you can use k vm, but the common thing across all is VirtualBox. Once the virtual machine comes up in the context of that virtual machine, the cdk will actually run a docker daemon write that darker daemon will go and pull OpenShift all in one image registry outside.

A

So if we are using CD K, this openshift are in one image will be pulled from registry. Read: access to Red, Hat comm. This all-in-one image is a complete, open shift cluster. It has both master and a single node all put together into one container image. So the next step is CD. K uses OC cluster up to start that OpenShift all-in-one image. If you have been following the openshift local environment on on your workstation, you might have used OC cluster up.

A

We use the same exact technology to start up a local OpenShift cluster, which is the all human image on this virtual machine. So you are, you have your workstation, you start a virtual machine in that virtual machine. There is a darker daemon running that goes and pulls the OpenShift all in one container image and runs it as an open, shaped container. That's how your open shaped environment is now. Once you have your open ship running, you can connect using JBoss developer studio, which is the IDE, and that IDE will interact with your openshift environment.

A

You can also use command line. You have both the options. So if you are using the JBoss development suite that comes with the CDK, you can actually start and stop. This open shift from the ID itself developer studio itself has an integrated adapter that will talk to your OpenShift running as cdk. Now, how do we expect this whole thing to be used? This is my thought on how it gets used as a developer.

A

You have your own local openshift cluster running on your workstation and that local openshift workstation is used by from your command line our ide to do the application development and you can go through the iterations, build the code test it when you are happy with with your code changes you push those code changes into a source control repository and at that point of time your code can be moved into a real OpenShift cluster, where you can do CI CD collaborate, your application development, along with other developers, QA motor production and the whole nine yards, so in summary, developers have their own local development environment that they can use with or without IDE on the local workstation, and they have a collaborative environment on a real open chef cluster.

A

That's how the whole thing comes together now in the next video we'll see how to setup cdk on your local machine using JBoss development suite thanks for watching.
