Ansible is a configuration management and orchestration application that was recently acquired by Red Hat. Rancher is a platform for working with Docker containers.
In the following blog post, originally published on the official Rancher blog, you’ll read how to use Ansible and Docker to deploy a WordPress service on Rancher.
The article begins:
Over the last year I’ve been using Rancher with Ansible, and have found that using the two together can be incredibly useful. If you aren’t familiar with Ansible, it is a powerful configuration management tool which can be used to manage servers remotely without a daemon or agent running on the host.

In this post, I will be using Ansible with Docker to automate the build out of a simple wordpress environment on a Rancher deployment. Specifically, I will include the following steps:
- Installing Docker on my hosts using Ansible.
- Setting up a fresh Rancher installation using Ansible.
- Registering hosts with Rancher using Ansible.
- Deploying the Application containers on the Hosts.
