Noissue - New module for installing docker on debian

modules/docker/manifests/init.pp

+# == Class: docker
+#
+# Install docker (https://www.docker.com/)
+#
+# == Parameters:
+#
+# [*source*]
+#  Overwrite the default apt::source used (given Class['apt'] is defined).
+#
+# [*package*]
+#   Overwrite the default package options, to fine-tune the target version (i.e.
+#   ensure => 'latest') or remove docker (ensure => 'absent' or 'purged')
+#
+# === Examples:
+#
+#   class {'docker':
+#     package => {
+#       ensure => 'latest',
+#     },
+#     source => {
+#       location => 'https://apt.dockerproject.org/repo',
+#       release => downcase("$::osfamily-$::lsbdistcodename"),
+#       include_src => false,
+#       key => '58118E89F3A912897C070ADBF76221572C52609D',
+#       key_server => 'hkp://ha.pool.sks-keyservers.net:80',
+#     }
+#   }
+#
