Chapter 2. Installing Dev Spaces

Procedure

1. Log in to Microsoft Azure:

   az login

   Copy to Clipboard

2. Create a resource group (to list the locations, use the az account list-locations command):

   # Resource group name
   ECLIPSE_CHE_RESOURCE_GROUP=eclipse-che
   
   # Azure region
   AZURE_REGION=centralus
   
   az group create --name $ECLIPSE_CHE_RESOURCE_GROUP --location $AZURE_REGION

   Copy to Clipboard

3. Create a cluster admins group:

   # Azure Active Directory group name
   AAD_GROUP_NAME=AKSAdmins
   
   az ad group create --display-name $AAD_GROUP_NAME --mail-nickname $AAD_GROUP_NAME

   Copy to Clipboard

4. Add the current user to the cluster admins group:

   az ad group member add --group $AAD_GROUP_NAME \
     --member-id $(az ad signed-in-user show --query id --output tsv)

   Copy to Clipboard

5. Create the Microsoft Entra integrated cluster:

   # Azure Kubernetes Service cluster name
   AKS_CLUSTER_NAME=eclipse-che
   
   az aks create \
     --resource-group $ECLIPSE_CHE_RESOURCE_GROUP \
     --name $AKS_CLUSTER_NAME \
     --enable-aad \
     --aad-admin-group-object-ids $(az ad group list --query "[?displayName=='$AAD_GROUP_NAME'].id" --output tsv) \
     --generate-ssh-keys

   Copy to Clipboard

6. Get the user credentials to access your cluster:

   az aks get-credentials \
     --resource-group $ECLIPSE_CHE_RESOURCE_GROUP \
     --name $AKS_CLUSTER_NAME \
     --admin

   Copy to Clipboard

7. Set kubelogin to use the Microsoft Azure CLI:

   kubelogin convert-kubeconfig -l azurecli

   Copy to Clipboard

8. View the pods in the cluster :

   oc get pods --all-namespaces

   Copy to Clipboard
9. Verification

Procedure

1. Install NGINX Ingress Controller:

   helm repo add ingress-nginx https://kubernetes.github.io/ingress-nginx

   Copy to Clipboard

2. Wait for the external IP. Note that a <pending> status for the external IP is shown before the exact external IP address is displayed.

   oc get services ingress-nginx-controller --namespace ingress-nginx
   NAME                                 TYPE           CLUSTER-IP     EXTERNAL-IP     PORT(S)                      AGE
