Deploy openshift local on azure

Pre-requisites
Create azure virtual machine
Connect to virtual machine
Install openshift local
Launch openshift local

This short write-up will explain how to deploy OpenShift Local on a Microsoft Azure Virtual Machine via nested virtualization.

Pre-requisites

Before we begin let's ensure we have the az Azure CLI installed. In my case I installed this via brew.

az version --output table

Azure-cli    Azure-cli-core    Azure-cli-telemetry
-----------  ----------------  ---------------------
2.77.0       2.77.0            1.1.0

Once the CLI is installed we need to ensure we have authenticated with Azure in our terminal. This guide assumes you have an existing Azure account.

az login

Lastly, after logging in this guide assumes you will already have an appropriate Azure Resource Group available to create the virtual machine within. You can check your Azure resource groups as follows.

az group list --output table

Name              Location    Status
----------------  ----------  ---------
openenv-jldt6     eastus      Succeeded
NetworkWatcherRG  eastus      Succeeded
aro-asl4w0j5      eastus      Succeeded

Create azure virtual machine

Update the variables below and run the az vm create command to create the new virtual machine.

One of the crucial aspects of this command is the --size parameter which is ensuring we will provision a virtual machine that supports Nested Virtualization.

Additionally we need to ensure the machine has at least 30Gi disk free for the OpenShift Local installation.

vmname="openshift-local"
username="openshift"
resourcegroup="openenv-jldt6"
location="eastus"
az vm create \
    --resource-group "${resourcegroup}" \
    --name "${vmname}" \
    --image "RHELRaw8LVMGen2" \
    --public-ip-sku Standard \
    --admin-username "${username}" \
    --size "Standard_D8_v5" \
    --ssh-key-values ~/.ssh/james.pub \
    --os-disk-size-gb 128

{
  "fqdns": "",
  "id": "/subscriptions/b9c5c8e5-1ac1-43a5-9d6b-1c9f4ff1cd1c/resourceGroups/openenv-jldt6/providers/Microsoft.Compute/virtualMachines/openshift-local",
  "location": "eastus",
  "macAddress": "00-0D-3A-9B-FB-38",
  "powerState": "VM running",
  "privateIpAddress": "10.0.0.10",
  "publicIpAddress": "172.171.221.17",
  "resourceGroup": "openenv-jldt6"
}

Connect to virtual machine

Once the machine is running we can connect to it via the az cli as follows.

Note: Depending on the azure vnet configuration in your environment you may need to configure network security settings to enable connectivity to the machine on port 22.

az ssh vm --ip <ip address>

Install openshift local

Once we've connected to our machine we need to download OpenShift Local and extract it.

wget https://developers.redhat.com/content-gateway/rest/mirror/pub/openshift-v4/clients/crc/latest/crc-linux-amd64.tar.xz
tar xf crc-linux-amd64.tar.xz

With the crc binary downloaded and extracted let's run the setup subcommand.

./crc-linux-2.54.0-amd64/crc setup

Launch openshift local

Once the setup process completes, we can launch OpenShift Local as follows.

Note: The initial launch can take ~15 minutes to complete as the cluster setup is performed.
