How to Deploy Galera Cluster for MySQL using Docker Containers
+0 Vote Up -0Vote Down
February 18, 2014 By Severalnines

Virtual Machines are great, and very useful when trying out new software. However, they might be an unnecessarily heavyweight solution when testing clusters, especially if these consist of multiple nodes running exactly the same software. Each VM runs a full-blown OS image. On the other hand, Linux Containers (LXC) are an efficient alternative to OS-level virtualization and can run multiple isolated systems on a single host. Docker is a wrapper around LXC, it automates the deployment of applications inside containers. 

A notable advantage if you run with Docker + LXC is you can run many containers on a single host.

Using MySQL with Docker

Regarding virtualization I am a LXC guy. Nevertheless Docker has won a lot of attention and I would like to show how to use MySQL with Docker.

What is Docker?

In fact Docker is a wrapper around LXC. It is fun to use. Docker has the philosophy to virtualize single applications using LXC. So in our example we are going to start a mysqld in a chroot environment encapsulated in his own Namespaces. (You can even set Cgroups resources.) One of the main points regarding Docker is the usage of a union filesystem (aufs). So when you start a Docker Container it gets his aufs mount and only changed data is written down.

Aufs is great for a lot of applications and sufficient for Database testing. I just want to share a simple - more educational, than effective - Dockerfile. Dockerfiles are the buildscripts for the Docker images.
