My name is august siminelli, I'm a field product manager within the cloud platform business unit at red hat. I work with customers around the world on bu led technical engagement. Today we are going to look at an exciting option for deploying openshift into the public cloud. Red hat. Open shift manage services in this demonstration, we're looking specifically at azure red hat openshift. Let's get started simply log in with your redhead account at cloud.redhat.com, once in you'll find many options to interact with red hat software.

A

So let's go ahead and open up the red hat cluster manager to begin azure, red hat openshift is jointly engineered, operated and supported by microsoft and red hat, with an integrated support experience it's available as an azure first party service, bringing true integration and innovation.

A

So when clicking the try it on azure link from the openshift cluster manager, you're taken to detailed instructions to quickly get a production grade, openshift cluster standing up on azure and it's these instructions that we'll be following in this demonstration before we can actually start creating our cluster and azure. We need to make sure of a few things. First make sure azure red hat openshift is available in your region.

A

You'll also need to make sure you have a pay-as-you-go account, not the free entry level account and that you have enough quota for the standard dsv3 family of vcpus.

A

The initial quotas allowed are 10, vcpus you'll need at least 40., so just use the normal azure process to request larger quota, for that instance, type and possibly for other instance types you might want to experiment.

A

With also go ahead and get your open shift pull secret, if you don't have it it's easy to find it from the red hat, openshift cluster manager and to just download to your local machine.

A

Now it's time to prep azure for our installation. First, we have to register the required resource providers against our subscription resource providers, provide granular access to azure's resources. So in general you register a provider only when you need it: registration, configures your subscription to work with each provider. Some resource providers are registered by default. Some are registered manually in advance like we're doing here, and other resource providers are registered automatically when you take certain actions that require them.

A

Openshift on azure install uses all types so for openshift on azure we're registering the red hat, openshift resource provider, microsoft's compute storage and authorization resource providers. We could, of course, do this via the azure portal through the ui, but it's really easy with the cli. So we just do it here well to be totally truthful, we're actually going to do the whole install from the cli. So, let's set some environment variables to make sure nothing gets set wrong.

A

Okay, let's make this thing. First, we create a resource group in azure. A resource group is a logical group in which, as your resources are deployed and managed, we have to set a location for this. This location is where resource group metadata is stored and sets the default location for resources if we don't explicitly set them in the future.

A

Now we're going to set up the networking for our cluster, so we're going to create a virtual network which is going to have two empty subnets uh one will be for the control plane and one will be for the workers and we build all this uh networking inside of the resource group we talked about earlier and next we build out the subnets, we're also explicitly setting a service endpoint and that's because azure guarantees a secure and direct route when we do that.

A

Lastly, we need to disable the subnet private endpoint policies for that master subnet. This is required for the service to be able to connect to and manage the cluster, and if we were using the portal to do it, it would be the default. You can read more in the documentation.

A

Now we're almost ready to create our cluster and we're going to use a really cool command for this. It's the aro create command, and I just want to show some of the things it can do through the help you can set your vm sizes. You can set things about your networks. You can set things around worker sizing. It can do a lot. So it's a really clever command.

A

So now we go ahead and build the cluster. We specify the resource group, the name of the cluster, the virtual network and the two subnets we created and I'm referencing my pull secret and with that it begins in my region. Installation took about 35 to 40 minutes.

A

You can track it via the console in azure or you could use the debug command and you could watch it on the cli, but in general it was completely hands off and I had a coffee and when I came back it was done and once the cluster is reporting complete, we now need to connect to it. So we use another cool arrow command to retrieve the details for the cluster.

A

But one thing to note here is that we could have used our own domain name with the dash dash domain flag on the a z arrow create command, and then we would just set it up in our own dns. Here we actually have a random url uh to connect to our cluster and there you have it with openshift on azure. You have full cluster admin, access for advanced, customization and management.

A

This gives you full control over upgrades and life cycle management. You also get a direct integration into things like azure storage into compute.

A

The ability to have scalable machine sets everything uh everything's multi-az, so you're, getting just total control of your cluster and, of course, logging in from a command line. Just as.

A

A

Another cool integration with azure is being able to configure azure red hat, open shift version, 4 with container insights, and, as you see here, azure has found our cluster and has registered it as unmonitored. So let's go ahead and set that up.

A

Okay. So what we're going to do is set up monitoring via azure red hat, open shift with container insights. Microsoft provides a script to set this up easily details on where and how to download are in the documentation.

A

So you set your resource id your resource group and your cluster name, and then you run the script which does all the work for you.

A

One thing I should point out is you do need your cli to have access to bash4 helm needs to be installed and the oc command, um but, like I said, the script takes you through everything uh it authenticates performs all the uh the setup creates. A namespace is required until you've got a working logging setup, which we'll take a look at in a minute I'll, go ahead and speed. This.

A

A

Once the script ran, uh the cluster was instantly monitored. You can see you go right back in and it's a monitored cluster and then you've got all the various dashboards that you might need now. My cluster took five minutes to start um to start gathering data. I've advanced this a little bit further, so we can go ahead and take a look at the the amazing amount of data that's being collected here.

A

Insights is is pretty cool. You can really dig right into the components of your openshift cluster. I mean you can query things um you can get right down to the the root of what's going on there. It's it's pretty spectacular and absolutely worth trying out.

A

And finally, deleting a cluster is as easy as creating one just a simple command: az aro delete when the command finishes. It took about 15 minutes in my region, the entire resource group and all the resources inside it, including the cluster, will be deleted.

A

As you can see, azure red hat openshift is pretty cool. It's an azure first party service, jointly engineered managed and supported by red hat and microsoft, inherits all of azure's compliance and allows you to use your as your billing deploying openshift to onto azure. Is it's easy, is fast and provides a completely managed service that allows you to focus on your applications. First and best of all azure red hat openshift is available. Now in your azure account, go give it a try and thanks for your time today,.
