Kolla Ansible's bootstrap-servers command provides support for installing the Docker engine. This is currently done using the packages at https://apt.dockerproject.org and https://yum.dockerproject.org. These packages are outdated, with the most recent packages from May 2017 - docker-engine-17.05. The source for up to date docker packages is https://download.docker.com, which was introduced with the move to Docker Community Edition (CE) and Docker Enterprise Edition (EE). This change adds support to bootstrap-servers for Docker CE for CentOS and Ubuntu. It also adds a new variable, 'enable_docker_repo', which controls whether a package repository for Docker will be enabled. It also adds a new variable, 'docker_legacy_packages', which controls whether the legacy packages at dockerproject.org will be used or the newer packages at docker.com. The default value for this variable is 'false', meaning to use Docker CE. Upgrading from docker-engine to docker-ce has been tested on CentOS 7.5 and Ubuntu 16.04, by running 'kolla-ansible bootstrap-servers' with 'docker_legacy_packages' set to 'false'. The upgrades were successful, but result in all containers being stopped. For this reason, the bootstrap-servers command checks running containers prior to upgrading packages, and ensures they are running after the package upgrade is complete. As mentioned in the release note, care should be taken when upgrading Docker with clustered services, which could lose quorum. To avoid this, use --serial or --limit to apply the change in batches.

Kolla-Ansible Overview
The Kolla-Ansible is a deliverable project separated from Kolla project.
Kolla-Ansible deploys OpenStack services and infrastructure components in Docker containers.
Kolla's mission statement is:
To provide production-ready containers and deployment tools for operating
OpenStack clouds.Kolla is highly opinionated out of the box, but allows for complete customization. This permits operators with little experience to deploy OpenStack quickly and as experience grows modify the OpenStack configuration to suit the operator's exact requirements.
