Molecule Vagrant Plugin

Molecule Vagrant is designed to allow use of Vagrant for provisioning of test resources.

Supported Platforms

This driver relies on vagrant command line which is known to be problematic to install on several platforms. We do our best to perform CI/CD testing on multiple platforms but some are disabled due to known bugs.

✅ MacOS with VirtualBox - GitHub Actions
✅ Fedora 32 with libvirt - Zuul
✅ Ubuntu Bionic (18.04) with libvirt - Zuul
❌ CentOS 8 with libvirt - Zuul DISABLED due to 1127 and 11020

Please do not file bugs for unsupported platforms. You are welcomed to create PRs that fix untested platform, as long they do not break existing ones.

Documentation

To use this plugin, you'll need to set the driver and platform variables in your molecule.yml. Here's a simple example using the fedora/32-cloud-base box:

driver:
  name: vagrant

platforms:
  - name: instance
    box: fedora/32-cloud-base
    memory: 512
    cpus: 1

Here's a full example with the libvirt provider:

driver:
  name: vagrant
  provider:
    # Can be any supported provider (virtualbox, parallels, libvirt, etc)
    # Defaults to virtualbox
    name: libvirt
  # Run vagrant up with --provision.
  # Defaults to --no-provision)
  provision: no
  # vagrant-cachier configuration
  # Defaults to 'machine'
  # Any value different from 'machine' or 'box' will disable it
  cachier: machine
  # If set to false, set VAGRANT_NO_PARALLEL to '1'
  # Defaults to true
  parallel: true
  # vagrant box to use by default
  # Defaults to 'generic/alpine316'
  default_box: 'generic/alpine316'

platforms:
  - name: instance
    # If specified, set host name to hostname, unless it's set to False and
    # the host name won't be set. In all other cases (including default) use
    # 'name' as host name.
    hostname: foo.bar.com
    # List of dictionaries mapped to `config.vm.network`
    interfaces:
      # `network_name` is the required identifier, all other keys map to
      # arguments.
      - auto_config: true
        network_name: private_network
        type: dhcp
      - network_name: private_network
        ip: 192.168.123.3
      - network_name: forwarded_port
        guest: 80
        host: 8080
    # List of raw Vagrant `config` options
    instance_raw_config_args:
      # use single quotes to avoid YAML parsing as dict due to ':'
      - 'vm.synced_folder ".", "/vagrant", type: "rsync"'
      # Run 'uname' a provisionning step **needs 'provision: true' to work**
      - 'vm.provision :shell, inline: "uname"'
    # Dictionary of `config` options. Note that string values need to be
    # explicitly enclosed in quotes.
    config_options:
      ssh.keep_alive: yes
      ssh.remote_user: 'vagrant'
      synced_folder: true
    box: fedora/32-cloud-base
    box_version: 32.20200422.0
    box_url:
    memory: 512
    cpus: 1
    # Dictionary of options passed to the provider
    provider_options:
      video_type: 'vga'
    # List of raw provider options
    provider_raw_config_args:
      - cpuset = '1-4,^3,6'
