Putting MySQL Cluster in a container
+1 Vote Up -0Vote Down
To get more familiar with docker and to create a test setup for MySQL Cluster I created docker images for the various components of MySQL Cluster (a.k.a. NDB Cluster)

At first I created a Fedora 20 container and ran all components in one container. That worked and is quite easy to setup. But that's not how one is supposed to use docker.

So I created Dockerfile's for all components and one base image.

The base image:
  • contains the MySQL Cluster software
  • has libaio installed
  • has a mysql user and group 
  • serves as a base for the other images
The management node (ndb_mgmd) image:
  • Has ndb_mgmd as entrypoint
  • Has a config.ini for the cluster

July 22, 2014 By Severalnines

We just wanted to make it official: Severalnines ClusterControl now supports MariaDB 10!

 

As most of you know will know by now, MariaDB 10 is the newest and most advanced version of the popular MariaDB relational database system. Whilst remaining application-compatible with the MySQL database, it adds many new capabilities to address the most challenging web and enterprise application use cases. Cluster deployments would be based on MariaDB Galera Cluster 10, which is a complete merge of MariaDB 10.0.12 and Galera Cluster.
