Usage example:

gitlab_additional_configurations:
  - gitlab_rails:
      - key: "time_zone"
        value: "Europe/Berlin"
  - nginx:
      - key: "listen_port"
        type: "plain"
        value: "80"
      - key: "listen_https"
        type: "plain"
        value: "false"

Resulting configuration:

gitlab_rails['time_zone'] = 'Europe/Berlin'
nginx['listen_port'] = 80
nginx['listen_https'] = false

Configurations via Ruby Function Calls

Ruby function calls that are not part of GitLab's configuration file can be given by Ansible role variables.

Usage example:

gitlab_ruby_configuration_calls:
  - key: "pages_external_url"
    value: "https://pages.example.com"
  - key: "registry_external_url"
    value: "https://registry.example.com"
  - key: "mattermost_external_url"
