Configuration & Environment Overrides

The cluster definition also supports overriding configuration properties and environment variables, either per role or per role group, where the more specific override (role group) has precedence over the less specific one (role).

Do not override port numbers. This will lead to faulty installations.

Configuration properties

Currently, not supported for config.yaml.

Environment variables

Environment variables can be (over)written by adding the envOverrides property.

For example per role group:

servers:
  roleGroups:
    default:
      config: {}
      envOverrides:
        MY_ENV_VAR: "MY_VALUE"
yaml

or per role:

servers:
  envOverrides:
    MY_ENV_VAR: "MY_VALUE"
  roleGroups:
    default:
      config: {}
yaml
