Varnish for Ansible

A role for deploying and configuring Varnish and extensions on unix hosts using Ansible.

It can additionally be used as a playbook for quickly provisioning hosts.

Vagrant machines are provided to produce a boxed install of Varnish or a VM for integration testing.

Supports

Supported Varnish versions:

• Varnish 3.x

Supported targets:

• Ubuntu 14.04 LTS "Trusty Tahr"
• Ubuntu 12.04 LTS "Precise Pangolin"
• Debian (untested)

Installation methods:

• Binary packages from the official repositories at Varnish

Callable tasks:

• vcl: Creates (or removes) a Varnish VCL configuration

Usage

Clone this repo into your roles directory:

$ git clone https://github.com/zenoamaro/ansible-varnish.git roles/varnish

And add it to your play's roles:

- hosts: ...
  roles:
    - varnish
    - ...

This roles comes preloaded with almost every available default. You can override each one in your hosts/group vars, in your inventory, or in your play. See the annotated defaults in defaults/main.yml for help in configuration. All provided variables start with varnish_.

You can also use the role as a playbook. You will be asked which hosts to provision, and you can further configure the play by using --extra-vars.

$ ansible-playbook -i inventory --extra-vars='{...}' main.yml

To provision a standalone Varnish box, start the boxed VM, which is a Ubuntu 12.04 box:

$ vagrant up boxed

You will find Varnish listening on the VM's 80 port on address 192.168.33.20 in the private network. You should probably, at minimum, point varnish_backend to the address:port of a webservice you want to cache.

Run the tests by provisioning the appropriate VM:

$ vagrant up test-ubuntu-trusty

At the moment, the following test boxes are available:

• test-ubuntu-precise
• test-ubuntu-trusty

Still to do

• Provide a simple way to route multiple VCL files
