Dots (.) in secretVolume name cause mounting error about charts

[hbagdi]

This is simply a naming thing and we likely won't fix it.

We can substitute the . with - in the template if the need be. Welcome a PR if you would like to add that.
An improvement to the doc is also welcome.

Please close this ticket if your issue is resolved. Thanks!

What if you change the name of the secret from my-secret to mysecret?

[oscarlofwenhamn]

My bad: previous secret name was on the form domain.com-wildcard, and thus

env:
  ssl_cert: /etc/secrets/domain.com-wildcard/tls.crt
  ssl_cert_key: /etc/secrets/domain.com-wildcard/tls.key

secretVolumes:
- domain.com-wildcard

Changing it to domain-wildcard fixed the error!
I imagine the issue being that punctuation in directory names have implications in the container OS. Is there any know naming convention for Kubernetes objects that recommends . not to be used in object names?
If not, I can't really think of an easy fix other than perhaps including in the chart a noted recommendation in naming convention for the secretVolumes entry.

I just realized the error message states as much as well:

Invalid value: "domain.com-wildcard": 
a DNS-1123 label must consist of lower case alphanumeric characters or '-', 
and must start and end with an alphanumeric character 
(e.g. 'my-name',  or '123-abc', regex used for validation is '[a-z0-9]([-a-z0-9]*[a-z0-9])?')

Doc PR done, might give another try to sorting the replace route if I find more time.

Closing since the core issue is a wontfix either way, remaining discussion can (if needed) be held in the PR comments instead.
