   Configure Cloud Shell

   Set up Cloud Shell by clicking the Cloud Shell button in the top-right corner of the screen:

   

   Configure Cloud Shell for Bash using the Advanced Settings. Use the existing subscription, resource group, and storage account. If your storage account does not populate, make sure that your Cloud Shell region matches the location where your Azure resources are deployed. To make the file share, choose Create new and specify okdcloudshell as the new file share.

2. Challenge

   Download SSH Keys for the Lab

   You will need to pull down the SSH keys so you can connect to the VMs using SSH. First make the .ssh directoy, if it isn't already there, with the mkdir command.

   Then, cd into the .ssh directory.

   Now, use wget to pull down the SSH keys using these links:

   wget https://raw.githubusercontent.com/ACloudGuru-Resources/content-openshift-origin-azure/master/ssh/id_rsa wget https://raw.githubusercontent.com/ACloudGuru-Resources/content-openshift-origin-azure/master/ssh/id_rsa.pub

   Change the permissions of the files to 400.

3. Challenge

   Run the Lab Prep Subscriptions

   You will need to connect to each VM using SSH and run a prep script.

   After you connect to a VM using SSH, you will first need to install wget if it is not already installed.

   We will need to download the associated script for the node found in the Git repo for the lab. The VM links are:

   • For the bastionVM-0 it would be: wget https://raw.githubusercontent.com/ACloudGuru-Resources/content-openshift-origin-azure/master/scripts/bastionhostPrep.sh
   • For the masterVM-0 it would be: wget https://raw.githubusercontent.com/ACloudGuru-Resources/content-openshift-origin-azure/master/scripts/masterPrep.sh
   • For the infraVM-0 it would be: wget https://raw.githubusercontent.com/ACloudGuru-Resources/content-openshift-origin-azure/master/scripts/infraPrep.sh
   • For the appnodeVM-0 it would be: wget https://raw.githubusercontent.com/ACloudGuru-Resources/content-openshift-origin-azure/master/scripts/nodePrep.sh

   Once the download completes, you will need to make the script executable.

   Finally, you would run the script. Make sure you use sudo or the script will fail.

4. Challenge

   Install OpenShift

   Use Ansible to run the prerequisites.yml and the deploy_cluster.yml playbooks to install OpenShift. Run these from the Bastion Host.

5. Challenge

   Deploy the OMS Agent in OpenShift

   Log in to the master node and use the OpenShift CLI tools to:

   1. Download the ocp-omsagent.yaml file from the Git repo:

   wget https://raw.githubusercontent.com/ACloudGuru-Resources/content-openshift-origin-azure/master/scripts/ocp-omsagent.yaml

   1. Create the omslogging project.
   2. Create a service account named omsagent.
   3. Add the cluster role cluster-reader to the service account.
   4. Set the Security Context Constraint to privileged for the service account.
   5. Deploy the agent using the oc create command.
