Summary

This class handles the repositories from which the puppetmasters pull

Overview

Parameters:

  • secure_private (Boolean) (defaults to: true)

    If false, /etc/puppet/private will be labs/private.git. Otherwise, some magic is done to have local repositories and sync between puppetmasters.

  • is_git_master (Boolean) (defaults to: false)

    If True, the git private repository here will be considered a master.

  • prevent_cherrypicks (Boolean) (defaults to: true)

    If true, setup git hooks to prevent manual modification of the git repos.

  • use_r10k (Boolean) (defaults to: false)

    If true, use r10k

  • enable_netbox

    If true, enable netbox repos

  • user (String[1]) (defaults to: 'gitpuppet')

    The user which should own the git repositories

  • group (String[1]) (defaults to: 'gitpuppet')

    The group which should own the git repositories

  • netbox_hiera_enable (Boolean) (defaults to: false)

    add the netbox-hiera repo

  • netbox_hiera_source (Stdlib::HTTPUrl) (defaults to: 'https://netbox-exports.wikimedia.org/netbox-hiera')

    The git source of the nebox hiera repo

  • netbox_hiera_path (Stdlib::Unixpath) (defaults to: '/srv/netbox-hiera')

    The repo path pf the nebox hiera repo

  • servers (Hash[String, Puppetmaster::Backends]) (defaults to: {})

    list of puppetmaster backend servers

  • r10k_sources (Hash[String, Puppetmaster::R10k::Source]) (defaults to: {})

    r10k_sources configuration
