In current CI/CD world, for DevOps tasks, many teams chose to use Bamboo API/Library running together with HELM chart and Kubernetes, to run actual deployemnt in Bamboo pipeline. You may get following weird error .

Error details & solutions

From the log description, it’s kind of a paradox, it claiming my-awesome-micro-service not exist, so trying to install it. At the meanwhile, it encounter one error saying this service already exist, so failed to install it.

The root cause is previous deployment failed to delete, so installing new version not work.

This is actually caused by finalizer in Kubenetes. If you check the service in LENS for this service’s deployment, you’ll find it.

The solution is simple, just delete this finalizer, you can run this via following command.

kubectl -n pretrade patch deployment/my-awesome-micro-service -p '{"metadata":{"finalizers":null}}'
