2 fixes:
- the first problem to resolve is that some volume names can have "-" in
the name. We now replace them by "_"
- the second problem is that k8s.io library truncates the lines and so
we cannot split the files by lines. We now "unwrap" the result.
TODO: globalize the `yaml.Marshal()` code to our own specific function
Underscores are forbidden by Kubernetes (should be a valid URL string),
we replace "_" by "-" in names, and we leave the values file using the
original name. So a volume named "foo_bar" in compose file, is
registered as "foo_bar" in the values file, but "foo-bar" is used as
volume name in deployments, volume claims, ...
- reduce complexity
- use better tools to format the code
- add more tests
- and too many things to list here
We are rewriting for V3, so these commits are sometimes big and not
fully detailed. Of course, further work will be more documented.
