For deploying Kubernetes service to Azure

Repository Structure

The server being deployed to Kubernetes is a Python simples HTTP server started using the command python -m http.server 7000 which opens up the server on port 7000. Running docker build -t http-simple-image . will build the Docker image, then running docker run --rm -it --name http-simple-instance -p 80:7000 http-simple-image will start the application. Navigate to localhost to hit the server.

The infrastructure as code is found in the terraform directory.

The manifests that configure the Kubernetes deployment can be found under the manifests directory.

Manual Steps Taken

  • I created an API token in TFCloud and added it to my Github Actions secrets.
  • Create a Service Principal. This generates authentication tokens that are required for Terraform. To create the service principal from the commandline run az ad sp create-for-rbac --name "azure-goof-tf" --role Contributor --scopes /subscriptions/<subscription id> --sdk-auth and put the credentials in your password manager
  • The clientID, clientSecret, subscriptionID, and tenantID from the previous step should be set as env vars in TFCloud
  • The clientID and clientSecret are also required by the AKS resource so add them as Terraform variables in TFCloud
  • The full JSON blob from that command was added as a secret in Github Actions
  • After Terraforming ACR I needed to get the username and password from the console to use as secrets in Github Actions
