Vagrant-friendly Docker Base Images

A collection of Vagrant-friendly docker base images + corresponding Vagrant baseboxes. Something inbetween the official distro base image and puhsion/baseimage, just enough to make it work with Vagrant.

On top of the official distro base image it includes:

• the vagrant user (password vagrant) with passwordless sudo enabled
• the vagrant insecure public key in ~/.ssh/authorized_keys
• sshd running in the foreground

Vagrant Baseboxes

The intended use of the Vagrant-friendly docker base images is to use them as a basebox in your Vagrantfile. These baseboxes simply reference one of the actual docker base images below.

The following baseboxes are currently published on Vagrant Cloud:

• tknerr/baseimage-ubuntu-18.04
• tknerr/baseimage-ubuntu-16.04
• tknerr/baseimage-ubuntu-14.04
• tknerr/baseimage-ubuntu-12.04

Usage

Use the config.vm.box setting to specify the basebox in your Vagrantfile.

For example, run vagrant init tknerr/baseimage-ubuntu-18.04 --minimal to create the Vagrantfile below:

Vagrant.configure(2) do |config|
  config.vm.box = "tknerr/baseimage-ubuntu-18.04"
end

Then, running vagrant up --provider docker should look similar to this:

W:\repo\sample>vagrant up --provider=docker
Bringing machine 'default' up with 'docker' provider...
==> default: Creating the container...
    default:   Name: minimal_default_1441605508
    default:  Image: tknerr/baseimage-ubuntu:18.04
    default: Volume: /w/repo/sample:/vagrant
    default:   Port: 0.0.0.0:2222:22
    default:
    default: Container created: f366398390f6b33f

    default: SSH address: 192.168.59.104:2222
    default: SSH username: vagrant
    default: SSH auth method: private key
    default:
    default: Vagrant insecure key detected. Vagrant will automatically replace
    default: this with a newly generated keypair for better security.
    default:
    default: Inserting generated public key within guest...
    default: Removing insecure key from the guest if it's present...
    default: Key inserted! Disconnecting and reconnecting using new SSH key...
==> default: Machine booted and ready!

Docker Base Images

In case you want to work with the actual docker base images directly, the following ones (see subdirectories) are available on docker hub:

• tknerr/baseimage-ubuntu:18.04
• tknerr/baseimage-ubuntu:16.04
• tknerr/baseimage-ubuntu:14.04
• tknerr/baseimage-ubuntu:12.04

Usage

You can use it in your Vagrantfile in it's most simple form like this and then run vagrant up:

Vagrant.configure(2) do |config|
  config.vm.provider "docker" do |d|
    d.image = "tknerr/baseimage-ubuntu:18.04"
  end
end

If you want to use provisioners, you need to additionally tell vagrant that this container has ssh enabled:

Vagrant.configure(2) do |config|
  config.vm.provider "docker" do |d|
    d.image = "tknerr/baseimage-ubuntu:18.04"
    d.has_ssh = true
  end

  # use shell and other provisioners as usual
  config.vm.provision "shell", inline: "echo 'hello docker!'"
end
