4. Github Dev Container und Codespace erstellen Source GitHub Codespaces icon: https://education.github.com/experiences/primer_codespaces
5. Erstelle ein neues Git repository  Mit den Konfigurationsdateien für den Dev-Container und für den GitHub Codespace:  https://github.com/patkoch/azure_terraform_codespace
6. Anmeldung bei der Azure Subscription mittels Azure CLI  az login // bei Azure anmelden  Credentials: siehe beigelegten Usernamen/Passwort
7. Terraform Configuration adaptieren und Bereitstellung  https://github.com/patkoch/terraform-azure-virtual-machine-linux  RSA Schlüssel erstellen ssh-keygen -t rsa -f id_rsa  terraform init # Connection to the backend  Terraform Configuration adaptieren (variables.tf)  id_rsa.pub Pfad in variables.tf hinzufügen/kontrollieren  terraform fmt # .tf files automatisiert formatieren  terraform validate # .tf files auf Syntax checken  terraform plan –out tfplan # Plan erstellen  terraform apply tfplan # Ressourcen laut Plan deployen
8. Verbinden zu der Ubuntu VM  chmod 600 id_rsa  ssh -i id_rsa adminuser@<public IP der Ubuntu VM auf Azure>  ls –la  exit
9. Ubuntu VM zerstören  terraform destroy # zerstört die Ressourcen
10. Task 2  Adapt your Dev Container: install kubectl  Update your kubeconfig file with the credentials of a Kubernetes cluster  Deployment of Linux Workloads on an Azure Kubernetes Cluster  Scaling the Workloads az aks get-credentials --resource-group myResourceGroup --name myAKSCluster Source AKS icon: Microsoft (Azure Public Service Icons)
