Demo setup for the "Automate every layer: Using Terraform to deploy, configure and maintain Azure Kubernetes clusters" talk.
NOTE: Run all commands from the root of the repository.
This repository includes a Dockerfile for building a Docker image containing az-cli, terraform, kubectl and kubectx/kubens. Build the image locally by running:
docker build . -t terraform-azcli
Run the container built in the previous step:
docker run --rm -it -v $(pwd):/code terraform-azcli
NOTE: All commands from this point on are ran inside this container.
Log into Azure. This is necessary for Terraform to be able to deploy to your Azure subscription:
az login
Enter the infrastructure directory:
cd /code/1-Infrastructure/
Set up Terraform:
terraform init
Get an overview of what will be created:
terraform plan --var="azure_region=[AZURE-REGION]" --out=terraform.tfplan
Finally, deploy the infrastructure:
terraform apply terraform.tfplan
This will create the resource group and Kubernetes cluster (should take about ~4 minutes).
Once the cluster is in place, set up the Kubernetes credentials locally (adjust the values as needed if they have been changed in the Terraform code):
az aks get-credentials --resource-group terraform-kubernetes-demo --name my-cluster
Enter the configuration directory:
cd /code/2-Configuration/
Set up Terraform:
terraform init
Get an overview of what will be created:
terraform plan --var="app_title=[TEXT TO SHOW ON APP]" --var="dns_label=[UNIQUE-DNS-NAME]" --out=terraform.tfplan
Finally, deploy the infrastructure:
terraform apply terraform.tfplan
To find the app's URL, run:
terraform output
For troubleshooting, check the ingress container's logs in the ingress-nginx namespace, and the app container's logs in the app namespace.
The easiest way to clean up all the created resources is by deleting the Azure resource group (adjust naming if needed):
az group delete -n "terraform-kubernetes-demo"
To perform a new test, all Terraform files in each directory can be cleaned by running the tr alias found in the Docker image.
