Mechanism to generate files from values

[brettaufheber]

It would be helpful to have a solution where files can be generated automatically. The data should be obtained from the values.

This mechanism creates correct entries near to the following properties in the statefulset.yaml file.

• extraVolumes
• extraVolumeMounts
• extraEnvFrom

The configuration part in the value properties should look like this:

filesGenerated:    # all files are "readOnly: true"
  data:
    MyFilename.raw:    # raw data
      defaultMode: 0555    # optional
      mountPath: /opt/test-data.txt
      content: "..."
  jsonData:    # converting YAML to JSON
    MyFilename.json:
      defaultMode: 0555    # optional
      mountDirPath: /opt    # constructs: /opt/MyFilename.json for mountPath
      content: "..."
  yamlData:    # must be valid YAML
    MyFilename.yaml:
      defaultMode: 0555    # optional
      mountDirPath: /opt    # constructs: /opt/MyFilename.yaml for mountPath
      content: "..."
