Docker

Linux containers (LXC) technology has taken off with Docker https://www.docker.com/ 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.

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

is a userspace interface for the Linux kernel containment features. Through a powerful API and simple tools, it lets Linux users easily create and manage system or application containers.
