clean-up

Clean-up

1. Un-deploy the applications/microservices on the workload clusters by removing the resources listed in gitops-workloads/<cluster-name>/kustomization.yaml
2. Un-deploy the tools installed in the workload clusters by removing the resources listed in gitops-system/clusters/<cluster-name>/kustomization.yaml. Wait for the tools to be uninstalled before you proceed to the next step.
3. Un-deploy the workload clusters by removing the resources listed in gitops-system/clusters-config/kustomization.yaml. Wait for all workload clusters to be fully deleted (including corresponding VPC) before you proceed to the next step.
4. Un-deploy the tools installed in the management cluster by removing the resources listed in gitops-system/clusters/mgmt/kustomization.yaml (except ./flux-system). Wait for the tools to be uninstalled before you proceed to the next step.
5. Un-deploy the management cluster.

   eksctl delete cluster --name mgmt --region $AWS_REGION
   

Note that eksctl delete cluster does not delete the hosting VPC; please delete it manually. 6. Remove the GitHub repos or AWS CodeCommit repos you created. - For GitHub you can use: gh repo delete --confirm product-catalog-api-manifests gh repo delete --confirm product-catalog-fe-manifests gh repo delete --confirm gitops-workloads gh repo delete --confirm gitops-system - If you performed the initial setup using CloudFormation, you can skip this step - the AWS CodeCommit repos will be deleted as part of the CloudFormation stack deletion. 7. Remove the secret in Secrets Manager. aws secretsmanager delete-secret --secret-id sealed-secrets --force-delete-without-recovery

8. Remove the crossplane role

   POLICY_ARN=$(aws iam list-attached-role-policies --role-name crossplane-role --query AttachedPolicies[0].PolicyArn --output text)
   aws iam detach-role-policy --role-name crossplane-role --policy-arn $POLICY_ARN
   aws iam delete-policy --policy-arn $POLICY_ARN 
   aws iam delete-role --role-name crossplane-role
   

9. Remove DynamoDB tables created by the product-catalog-api application. You can list tables starting with "product-" using:

   aws dynamodb list-tables --query "TableNames[?starts_with(@, 'prod') == \`true\`]"
   

   Then delete individual tables using:

   aws dynamodb delete-table --table-name <table-name>
   

10. Delete the IAM user that was used to interact with the CodeCommit repos from the Cloud9 environment, and from the EKS clusters by the Flux source controller. Also, delete the associated IAM policy. Skip this step if you used CloudFormation to perform the initial setup.

11. If you used CloudFormation to perform the initial setup, delete the corresponding CloudFormation stack:

    aws cloudformation delete-stack --stack-name gitops-initial-setup
