Use this command to create a clone of this site locally
git clone https://github.com/maysay1999/aro.git AroDemo01

1. Create Ubuntu VM for Trident

Create a new resource group (anf-demo-aks-prework.azcli) az group create -n arotest-rg -l japaneast
Create Ubuntu VM ARM for Ubuntu

2. Create VNet and Subnets (create-subnet.azcli)

git clone https://github.com/maysay1999/aro.git AroDemo01

Resource group: arodemo-rg
VNet name: aro-vnet
Master Node subnet: master-subnet
Worker Node subnet: worker-subnet
Register the Microsoft.RedHatOpenShift resource provider:
az provider register -n Microsoft.RedHatOpenShift --wait
Running shell
chmod 711 create-subnet.sh
./create-subnet.sh

3. Create ARO cluster

Resource group: arodemo-rg
Cluster name: AroCluster01

az aro create \
  --resource-group arodemo-rg \
  --name AroCluster01 \
  --vnet aro-vnet \
  --master-subnet master-subnet \
  --worker-subnet worker-subnet

Note: It takes about 35 minutes.

4. Install kubectl, helm, az cli and git on Ubuntu

Install kubectl, helm, az cli and git

sudo apt update && \
sudo snap install kubectl --classic && \
sudo snap install helm --classic && \
curl -sL https://aka.ms/InstallAzureCLIDeb | sudo bash && \
sudo apt install git-all -y

5. az login to Azure on Trident VM

az login --use-device-code
https://microsoft.com/devicelogin
Verify with this command kubectl get deployments --all-namespaces=true
Set as default account if necessary az account set -s SUBSCRIPTION_ID

6. Connect to an Azure Red Hat OpenShift cluster

Obtain password of "kubeadmin":

az aro list-credentials \
  --name AroCluster01 \
  --resource-group arodemo-rg

7. Login

Obtain URL and login on OpenShift console

az aro show \
  --name AroCluster01 \
  --resource-group arodemo-rg \
  --query "consoleProfile.url" -o tsv

8. Install the OpenShift CLI

Home directory: cd
Download OpenShift CLI: curl -L -O -C - https://mirror.openshift.com/pub/openshift-v4/clients/ocp/latest/openshift-client-linux.tar.gz
Make a new dierctory: mkdir openshift
CD to openshift and Extract: cd openshift && tar xzvf ../openshift-client-linux.tar.gz
Edit .bashrc: echo 'export PATH=$PATH:~/openshift' >> ~/.bashrc && source ~/.bashrc

9. Connect using the OpenShift CLI

Retrieve API server: apiServer=$(az aro show -g arodemo-rg -n AroCluster01 --query apiserverProfile.url -o tsv)
Login to the OpenShift cluster's API server: oc login $apiServer -u kubeadmin -p xGU3N-33F3a-j7H3n-Nfake
Verify that you are a Kubernetes cluster administrator: oc auth can-i '*' '*' -A

10. Install Trident

Back to home direcotory: cd
Download Trident curl -L -O -C - https://github.com/NetApp/trident/releases/download/v21.10.0/trident-installer-21.10.0.tar.gz
Extract tar tar xzvf trident-installer-21.10.0.tar.gz
Copy tridentctl to /usr/bin/ cd trident-installer && sudo cp tridentctl /usr/local/bin/
Create a Trident Namespace oc create ns trident
Install trident with helm cd helm && helm install trident trident-operator-21.10.0.tgz -n trident

11. Create Service Principal

Creaete a new SP named "http://netapptridentaroxxx" az ad sp create-for-rbac --name "http://netapptridentaroxxx"
Gain Subection ID az account show --query id -o tsv
Gain NetApp Account ID: az netappfiles account show -n $anf_name -g arodemo-rg --query id -o tsv

12. Create role assignment

anfac=$(az netappfiles account show -n $anf_name -g arodemo-rg --query id -o tsv)
appid=xxxxxxxxxxxxxxxx

az role assignment create --scope $anfac --assignee $appid --role contributor
