roles

Fabricio: infrastructures

This example shows how to use roles within different infrastructures. There are one role and one infrastructure defined in fabfile.py. But you can define as many additional roles and infrastructures as you need.

Requirements

• Fabricio 0.3.19 or greater
• Vagrant
• One from the list of Vagrant supported providers (this example was tested with VirtualBox)

Virtual Machine creation

Run vagrant up and wait until VM will be created.

Files

• fabfile.py, Fabricio configuration
• README.md, this file
• Vagrantfile, Vagrant config

List of available commands

fab --list

Deploy

To deploy to a particular infrastructure you need to provide its name before any other command:

fab vagrant nginx

This command will start deploy of nginx container to the vagrant infrastructure. Vagrant virtual machine creation will start automatically if needed.

Also you can use vagrant.confirm command to skip confirmation dialog and start tasks execution immediately.

If no infrastructure selected then Fabricio will use Fabric's default roles definition (see fabfile.py for details). Also if there is no hosts found for a role then any task which needs to be executed on a remote host will be skipped.

Parallel execution

Any Fabricio command can be executed in parallel mode. This mode provides advantages when you have more then one host to deploy to. Use --parallel option if you want to run command on all hosts simultaneously:

fab --parallel vagrant.confirm nginx

Choosing infrastructure using parallel mode only available with .confirm suffix due to limitations of Fabric

Customization

See "Hello, World" Customization section.

Issues

• If you see warnings in Vagrant logs about Guest Extensions version is not match VirtualBox version try to install vagrant-vbguest plugin that automatically installs Guest Extensions of version which corresponds to your version of VirtualBox: vagrant plugin install vagrant-vbguest
