Cleanup

⏱ Estimated time: 15 minutes

Running Google Cloud or AWS resources will continue to incur costs on your account so we have documented all the steps to take for a proper tear-down.

Automated cleanup

Cloud-specific steps

There are a few cloud-specific steps you'll need to take.

GCP

In order to delete some non-Kubernetes resources created by Google Cloud, it's easiest to just delete everything:

kubectx apollo-supergraph-k8s-dev
kubectl delete daemonsets,replicasets,services,deployments,pods,rc,ingress --all --all-namespaces

The command may hang at the end. You can kill the process (ctrl-c) and repeat with the prod cluster:

kubectx apollo-supergraph-k8s-prod
kubectl delete daemonsets,replicasets,services,deployments,pods,rc,ingress --all --all-namespaces

AWS

In order to ensure the load balancers are properly removed, and the IAM service roles are removed, please run:

gh workflow run "Uninstall Router" --repo $GITHUB_ORG/reference-architecture
open https://github.com/$GITHUB_ORG/reference-architecture/actions/workflows/uninstall-router.yaml

Wait for the action to complete on the opened screen, and once finished, run the following, replacing apollo-supergraph-k8s with the appropriate cluster prefix if modified:

# dev
eksctl delete iamserviceaccount \
    --cluster=apollo-supergraph-k8s-dev \
    --name="aws-load-balancer-controller" 
aws cloudformation delete-stack --stack-name eksctl-apollo-supergraph-k8s-dev-addon-iamserviceaccount-kube-system-aws-load-balancer-controller
# prod
eksctl delete iamserviceaccount \
    --cluster=apollo-supergraph-k8s-prod \
    --name="aws-load-balancer-controller" 
aws cloudformation delete-stack --stack-name eksctl-apollo-supergraph-k8s-prod-addon-iamserviceaccount-kube-system-aws-load-balancer-controller

Remaining steps

Then you can destroy all the provisioned resources (Kubernetes clusters, GitHub repositories) with terraform:

cd terraform/<cloud_provider>
terraform destroy # takes roughly 10 minutes

Lastly, you can remove the contexts from your kubectl:

kubectl config delete-context apollo-supergraph-k8s-dev
kubectl config delete-context apollo-supergraph-k8s-prod

Terraform does not delete the Docker containers from GitHub. Visit https://github.com/<your github username>?tab=packages and delete the packages created by the previous versions of the repos.
