When you have finished with a namespace, please clean it up (i.e. remove it).
This helps to keep the cloud platform repositories well-organised, and speeds up deployments and changes to the cluster (because the build process doesn’t have to spend time managing unnecessary resources). It also deletes the associated AWS resources, and helps to keep our hosting costs down.
So, if your namespace is called
mynamespace, then you need to raise a PR
deleting the folder:
…and all its contents, from the cloud-platform-environments repository.
NB: If you have set up a CI/CD pipeline, which deploys into your namespace, then this should be deleted first, so that anything you delete later is not immediately recreated by your build pipeline.
