If you just want to delete the
kubectl context of a space you can run:
devspace remove context [SPACE_NAME]
This command will remove the kube context for the given space from your
kubectl config. If you want to delete the complete namespace and all resources in it you can run:
devspace remove space [SPACE_NAME]
This will remove all deployed resources from the space and delete the isolated namespace. In addition this does also delete the kube context for the space used locally.
Warning: Deleting a Space will also delete all the persistent volumes defined in this Space. Your data will be lost forever and cannot be recovered again.
