Docker on FreeBSD is genuine Docker and retrieves containers from the official docker.io repository. Consult the official Docker documentation and resources for further assistance.
Status
Docker's currently broken. We are working on a current, executable version. Help is welcome. Current status: https://reviews.freebsd.org/D21570
Limitations of the 64bit Linux compatibility subsystem will impact some Linux ABI containers and your testing and feedback is appreciated to help resolve any such issues.
The centos dockerfile has a default command bash. That means, when run in background (-d), the shell exits immediately.Update 2017. More recent versions of docker authorize to run a container both in detached mode and in foreground mode (-t, -i or -it). Docker on FreeBSD.

How to install and use Docker CE on a CentOS Linux 7 server? Docker is free and open-source software. It automates the deployment of any application as a lightweight, portable, self-sufficient container that will run virtually anywhere. Typically you develop software on your laptop/desktop. $ docker commit 4f0b435cdbd7 man-centos $ docker run -i -t man-centos root@953c512d6707 /# man man No manual entry for man. Now we have a CentOS container where man is already installed. I can’t (that I know of) inspect the container and know whether or not man is installed without running it.
The freebsd-virtualization mailing list, as well as the IRC channels #freebsd-docker and #bhyve on chat.freenode.net are good places to participate.
Requirements
FreeBSD 11.1-RELEASE or newer, specifically any version after preliminary support for x86-64 Linux binaries was addded.

Installation and Use
The following steps, executed with root privileges, should provide a working Docker environment:
If you're not already using ZFS, you will need to create a raw disk, otherwise follow the above steps as instructed in the package message.
Using Docker as a normal user
In order to use Docker as a non-root/non-super user account, your user must be in the operator group:
After changing your user's group membership, log out and back in. Once logged back in docker ps should be usable (for example) as a non-superuser.
From another terminal:
Creation of a ZFS root using raw disk
These steps are only necessary if you're not already using ZFS.
The following steps allocate a 4G ZFS root file system using a raw disk, it allows you to test quickly.
