Linux containers (LXC)[1] technology has taken off with Docker https://www.docker.com/ [2][3] which was released as open source in March 2013. RedHat and others have collaborated with the corporate backer to the technology seemingly to compete with Canonical's JuJu https://juju.ubuntu.com/ and Charm technology which also is based on Linux containers. Linux containers are built into the linux kernel, and so offer a lightweight native method of virtualization compared to more traditional (heavyweight) virtualization techniques like VMWare.

Bring your own Node

Docker Cloud lets you use your own host as a node to run containers. In order to do this, you have to first install the Docker Cloud Agent.

curl -Ls https://get.cloud.docker.com/ | sudo -H sh -s 7521e_PRIVATEKEY_7521e

And you must have incoming port 2375 open plus have 6783tcp/udp open

The following Linux distributions are supported:

  • Ubuntu 14.04, 15.04
  • Debian 8
  • Centos 7
  • RedHat Linux 7
  • Fedora 21, 22

Pricing

Pricing depends on whether it's cloud or premise (datacenter), and ranges from $15/mo for a single node in the cloud to $150 or $300/mo per node for datacenter engine depending on the level of support.[4]


Installing on Ubuntu

https://docs.docker.com/installation/ubuntulinux/ Apparently the packaged version is old (not surprising). So, add the Docker repo, and install lxc-docker Note: it's only supported on 64-bit Ubuntu
