Example Vagrant multi-host project with Ansible

Host are provisioned with Ansible.

Virtual machine are created either with VirtualBox or with QEMU. Please see rebuild-all script for that. That script uses QEMU.

Please see Vagrant documentation for details how to use it. The quick tutorial is as follows:

• vagrant up - starts all virtual machines, provision them if necessary
• vagrant provision - provision already created virtual machines again - in this case it would be Ansible playbook in provisioning/site.yml
• vagrant halt - stop all created virtual machines

After Vagrant installs machines the first time it will spin up much faster the next time.

Once the virtual machines are up, you connect to with vagrant ssh ex01, etc, command.

Once the system is fully started, you connect to with:

• http://ex01.multihostexample.dev
• http://ex02.multihostexample.dev
• http://ex03.multihostexample.dev
• http://ex04.multihostexample.dev

Requirements

• VirtualBox >= 4.3.26 or QEMU, ideally with KVM
• Ansible >= 1.9.0
• Vagrant >= 1.7.0

VirtualBox

Virtualbox binaries are available at its download page and follow the instruction there.

QEMU

QEMU is available as Linux packages in the modern distributions. Vagrant needs Vagrant Libvirt Provider - this can be installed with vagrant plugin install vagrant-libvirt

Ansible

Please follow installation instructions in the Ansible documentation.

Please note: as there isn't Ansible implementation for MS Windows, this example won't start Ansible provisioner on that platform.

Vagrant

Installing Vagrant is extremely easy. Head over to the downloads page and get the appropriate installer or package for your platform. Then install it using standard procedures for your operating system.

The installer will automatically add vagrant to your system path so that it is available in terminals. If it is not found, please try logging out and logging back in to your system (this is particularly necessary sometimes for Windows).
