Docker-enabled Vagrant boxes

Purpose

Some Linux distributions don't have a pre-installed Docker engine. Public Vagrant boxes (e.g., those in Vagrant Cloud and Vagrantbox.es) also lack quality support for Docker. So I build these Vagrant boxes to aid my Docker development.

I also install some handy tools for Docker.

For the impatient

Use the following public box names (all available from Atlas service):

• Ubuntu 14.04.x LTS ("Trusty") x64:

  • williamyeh/ubuntu-trusty64-docker, basically ubuntu-14.04.3-server-amd64 + Docker

  • williamyeh/insecure-registry, basically williamyeh/ubuntu-trusty64-docker + Docker Registry 2.x

• Debian 8 ("Jessie") x64:

  • williamyeh/debian-jessie64-docker, basically debian-8.2.0-amd64 + Docker

  • williamyeh/k8s, basically williamyeh/debian-jessie64-docker + Kubernetes

• CentOS 7 x64:

  • williamyeh/centos7-docker, basically CentOS 7.1 + Docker

Included software

• Docker Engine

• Docker CLI

• Docker Compose (was: Fig): Fast, isolated development environments using Docker.

• Docker Swarm: a Docker-native clustering system.

• Docker Machine: Machine management for a container-centric world.

• docker-bench-security: a script that checks for all the automatable tests included in the CIS Docker 1.6 Benchmark.

• dockviz: Visualizing Docker data (docker images --tree replacement).

• Pipework: Software-Defined Networking for Linux Containers.

• docker-gen: Generate files from docker container meta-data.

• dockerize: Utility to simplify running applications in docker containers.

• cAdvisor: Analyzes resource usage and performance characteristics of running containers.

• weave: creates a virtual network that connects Docker containers deployed across multiple hosts and enables their automatic discovery.

• Docker host tools: Some handy tools for managing Docker images and containers (also written by me).

• Docker Registry 2.x (only provided in williamyeh/insecure-registry box)

• Kubernetes (only provided in williamyeh/k8s box)

Build these boxes yourself

Here are steps you can follow to build these boxes on your own.

First, install the Packer tool on your host machine.

Second, pull the Bento submodule:

# pull the Bento project
git submodule init

# copy Bento stuff to sub-directories
# since Packer doesn't push soft links to Atlas (defects!)...
./copy-bento.sh

Third, choose the box directory of your choice:

# change working directory to any specific OS;
# for example, "ubuntu-trusty"
cd ubuntu-trusty

Now, you can either generate the Vagrant box file on your machine:

# build `ubuntu-trusty64-docker`:
packer build ubuntu-trusty64-docker.json


# build `ubuntu-trusty64-docker`, VirtualBox version only:
packer build -only=virtualbox-iso  \
       ubuntu-trusty64-docker.json


# build `ubuntu-trusty64-docker`, VirtualBox version only,
# with pre-downloaded ISO file from `file:///Volumes/ISO/`:
packer build -only=virtualbox-iso  \
       -var 'mirror=file:///Volumes/ISO/'  \
       ubuntu-trusty64-docker.json

you'll get an 'XXX.box' file in the builds directory, if successful.

Or, you can delegate the building and hosting tasks to Atlas:

# make sure the following environment variables are set:
#   ATLAS_TOKEN
#   ATLAS_USERNAME
packer push ubuntu-trusty64-docker.json

Alternatives

Some nice alternatives you may try:

• Ubuntu 14.04 LTS ("Trusty") x64:

  • 3scale/docker

• CentOS 6.x x64:

  • jdiprizio/centos-docker-io

• CoreOS x64:

  • yungsang/coreos (stable)
  • yungsang/coreos-beta
  • yungsang/coreos-alpha
