# == Class: tripleo::profile::base::docker
#
# docker profile for tripleo
#
# === Parameters
#
# [*insecure_registries*]
#   An array of host/port combiniations of insecure registries. This is used to configure
#   /etc/sysconfig/docker so that local (insecure) registries can be accessed.
#   Example: ['127.0.0.1:8787']
#   (defaults to unset)
#
# [*registry_mirror*]
#   Configure a registry-mirror in the /etc/docker/daemon.json file.
#   (defaults to false)
#
# [*docker_options*]
#   OPTIONS that are used to startup the docker service.  NOTE:
#   --selinux-enabled is dropped due to recommendations here:
#   https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/7.2_Release_Notes/technology-preview-file_systems.html
#   Defaults to '--log-driver=journald --signature-verification=false --iptables=false'
#
# [*configure_storage*]
#   Boolean. Whether to configure a docker storage backend. Defaults to true.
#
# [*storage_options*]
#   Storage options to configure. Defaults to '-s overlay2'
#
# [*step*]
#   step defaults to hiera('step')
#
# [*debug*]
#   Boolean. Value to configure docker daemon's debug configuration.
#   Defaults to false
#
# DEPRECATED PARAMETERS
#
# [*insecure_registry_address*]
#   DEPRECATED: The host/port combiniation of the insecure registry. This is used to configure
#   /etc/sysconfig/docker so that a local (insecure) registry can be accessed.
#   Example: 127.0.0.1:8787 (defaults to unset)
#
# [*docker_namespace*]
#   DEPRECATED: The namespace to be used when setting INSECURE_REGISTRY
#   this will be split on "/" to derive the docker registry
#   (defaults to undef)
#
# [*insecure_registry*]
#   DEPRECATED: Set docker_namespace to INSECURE_REGISTRY, used when a local registry
#   is enabled (defaults to false)
#
