Docker is an open platform for developers & sysadmins to build, ship, and run distributed applications, whether on laptops, datacenter VMs, or the cloud. Containers allow application developers an increased level of portability and convenience in packaging complete complex applications for use.

In September 2017, Docker announced multi-architecture support, allowing supported platforms (including arm64) to load and run many official images. The system automatically selects the right architecture for your platform. Many, but not all, of the official Docker releases of software have been thus distributed in this multi-architecture format.

Docker produces monthly releases as a rolling snapshot of development work. Stable releases are produced quarterly. Details about the latest updated release, 18.06.1-ce of August 21, 2018, can be reviewed at the Docker CE release notes page.

Installing Docker

As of late September 2017 the latest Docker 17.06-ce works on arm64 servers running Ubuntu 16.04, using the installation instructions that are identical to all other distributions.

For Ubuntu 16.04 LTS, install Docker 1.12.6 with apt-get install docker.io on the Packet Type 2A server.

For Centos 7, install Docker 1.12.5 with yum install docker.
