Cockpit

The Hiera example below will install and activate the web based management interface Cockpit plus eventually some required modules:

base::package_groups:
  - 'cockpit'

base::pkg_group::cockpit:
  - 'cockpit'
  - 'cockpit-...'

base::sockets:
  cockpit:
    enable: true

If you would like to disallow access from externally and only allow connections from the host itself, then extend the socket configuration as below:

base::sockets:
  cockpit:
    enable: true
    dropin: true
    options:
      Socket:
        ListenStream: ['', '[::1]:9090']
