Development

Howto

1. We use GitHub Flow.
   1. Create a branch derived from branch master.
   2. Make your changes and test them.
   3. Create a Pull Request.
   4. Verify that all checks pass. If not, fix the issues on your branch and push them again.
   5. Wait for your Pull Request to be reviewed.
   6. After successful Review, your Pull Request will be merged.
2. Several checks run on a Pull Request. They all need to pass, otherwise your changes will not be accepted.
3. In case you are doing changes on a helm chart
   1. Bump the version in Chart.yaml,
   2. Run pre-commit run -a to update the documentation. Please use Helm-Docs 1.8.1.
4. After your Pull Request has been accepted and has been merged to master branch, an automated process will create a new Release of the modified helm charts.

Some checks are failing? What can I do?

• Detect-Secrets checks are failing? Check if all "detected secrets" are false positives.

  You can mark false positives, see here

  E.g.

  # 1. Secret and comment in same line (note: not always working):
  
  SomeSecretString # pragma: allowlist secret
  
  # 2. Comment one line above Secret:
  
  # pragma: allowlist nextline secret
  SomeSecretString
  
  # 3. For helm template comments:
  
  {{- /*
      # pragma: allowlist nextline secret
  */}}SomeSecretString
  
  # 4. For helm values.yaml (which will be used to generate docs via helm-docs)
  # Note: a) Add   <!-- # pragma: allowlist secret -->   one line before the value as it becomes part of the generate doc file.
  #       b) Add   # pragma: allowlist secret            at the end of the line which contains the value.
  
  # -- Description for 'sha'.
  # Additional line of description.
  # IMPORTANT: There must be two space characters between end of the value and the '#' character that starts the comment.
  # <!-- # pragma: allowlist secret -->
  sha: "f9814e1d2f1be7f7f09addd1d877090fe457d5b66ca2dcf9a311cf1e67168590"  # pragma: allowlist secret
