External Secrets and Immutable Target

If you have worked with External Secrets Operator before, then you know how it eases the operation of managing the secrets in the Kubernetes cluster. It supports many backends and is very powerful.

However, there is a nuance. The External Secrets Operator allows you to define an immutable target secret, sealing the secret shut from future changes unless explicitly deleted and recreated, which is perfect if you never want to modify the secret. But, change is the only constant in the world of IT, and you might want to change the secret in the future. This is where immutable can catch you off guard, as it did mine. This is my story and how I solved it.
