docker-host

docker-host uses Vagrant to provide an experience similar to boot2docker, and serves as a seamless layer for interacting w/ docker through the host operating system.

docker-host has a very simple ansible playbook called docker-host.yml that configures the the docker daemon living in the docker-host as well as sets up a seamless private network to interact with the docker-host through the host operating system -- OSX and Linux systems are supported only for now.

The main purpose of docker-host is to essentially serve a virtual machine that runs the docker daemon. This becomes the basis of an execution environment for all docker images, used in the instructions further below, in which a shared virtual machine executes all the docker images and exposes them via the host machine's command-line client.

Instructions

OSX

To get started, on your host system, you need:

  • Ansible 1.8.2+
  • Vagrant 1.7+
  • docker v1.6.0

brew commands

  • brew install ansible
  • brew cask install vagrant
  • vagrant plugin install nugrant
  • brew install docker

LINUX

(todo)

Play

Then, vagrant up docker-host - wait until it's done.

Then, export DOCKER_HOST=10.2.0.10:2375 (probably should put that in your ${shell}rc or ${shell}profile).

To test a successful installation, type in docker ps from your host machine cli and you should see:

When done provisioning, docker login to set credentials.
