Azure Kubernetes Service (AKS) Workshop

• Azure subscription with Owner role
  • Why? Because we need to assign permissions e.g., AcrPull and others
• Azure subscription should be enabled for creating following resources:
  • Multiple Azure Virtual Networks
    • User Defined Routes (UDR)
    • Network Security Groups (NSG)
  • Private DNS Zone
  • Virtual Machine
  • Bastion Host
  • Azure Container Registry (ACR)
  • Azure Kubernetes Service (AKS)
  • Azure Container Instances (ACI)
  • Azure Storage Account
    • NFS fileshare
    • Private endpoint
  • Azure Application Gateway
  • Azure Log Analytics Workspace
• Each person should have their own dedicated resource group
  • Why? Because we need to test AKS cluster upgrades and other operations that require personal environments
• Azure Cloud Shell available
  • If you want to run this locally, then you need to have Azure CLI, jq, envsubst, and helm installed
• Entra ID Group that contains all workshop participants
  • Why? Because we need have group for AKS cluster admin access
    • You only need to have Object ID of the group
    • You can use My Groups to find group that you're member of. You can see Object ID of the group in URL.

1. Open Azure Cloud Shell
   • Use Bash
   • Use clouddrive folder for persisting files in Azure Cloud Shell
   • To prevent cloud shell for timing out, you can use following keep_alive trick in 00-variables.sh script:

   while :; do echo 'Hit CTRL+C'; sleep 1; done

• If cloud shell does timeout, then you can recover variable state using these steps:
  1. Run 00-variables.sh to restore variable values
  2. Update authorized IP ranges to AKS:

  my_ip=$(curl -s https://myip.jannemattila.com)
  az aks update -g $resource_group_name -n $aks_name --api-server-authorized-ip-ranges $my_ip

  3. Get credentials for connecting to AKS:

  az aks get-credentials -n $aks_name -g $resource_group_name --overwrite-existing

  4. Test connectivity to API Server:

  kubectl get nodes

• Alternative environment options: Use WSL or Linux
• Pre-reqs for alternative environment:
  • Azure CLI
  • Optional VS Code
    • Execute different script steps one-by-one in VS Code (hint: use shift-enter)

2. Clone this repo

git clone https://github.com/JanneMattila/aks-workshop.git

• Good idea to clone this also to local machine for better readability and usability

3. Start deployments by opening 00-variables.sh and follow the instructions
