In the documentation from kubernetes you can read: https://v1-18.docs.kubernetes.io/docs/concepts/configuration/secret/#creating-a-secret-manually
The keys of data and stringData must consist of alphanumeric characters, '-', '_' or '.'.
I think it could be a good to force this so that developers dont add stuff to their secret config not compatible with k8s.
But im not sure the regex is correct according to the k8s spec for accepted values
edit:
Added ability for multiline envs. delimiter&&
can be replaced with something more elegant/right?edit 2:
A better approach is to use
\
backslash for separate env. vars?
