generate Command

The generate command is used to generate secrets and configmaps from a configuration .yaml, interpolating it with environment variables when necessary and saves the generated files in a specified directory.

Flags:

• --config-file: config file that contains all ConfigMaps and Secrets definitions
• --env-prefix: prefixes to add when looking for environment variables
• --out: output directories where interpolated fileNames are saved

The configuration file supports environment variable interpolation following the regular expression {{[A-Z0-9_]+}}. The interpolation works in the same way described in the interpolate command. The file has a secrets section where tls,docker,data are mutually exclusive and a config-maps section where the only section supported is data. The file has the following schema:

secrets:
  - name: "foo"
    when: "always|once"
    tls:
      cert:
        from: "literal|file"
        file: /path/to/file
        value: value
      key:
        from: "literal|file"
        file: /path/to/file
        value: value
    docker:
      username: user
      password: pass
      email: example@mail.com
      server: example.com
    data:
      - from: "literal|file"
        file: ./path
        key: key
        value: value
config-maps:
  - name: "pippo"
    data:
      - from: "literal|file"
        file: ./path
        key: key
        value: value
