MySQL on Docker: ClusterControl and Galera Cluster on Docker Swarm

This blog post shows our experimentation on running ClusterControl and Galera Cluster on Docker Swarm.

How to Deploy Asynchronous Replication Slave to MariaDB Galera Cluster 10.x using ClusterControl

Combining Galera and asynchronous replication in the same MariaDB setup, aka Hybrid Replication, can be useful as we’ve discussed previously. This new post takes things further and shows you how to deploy an asynchronous replication slave to MariaDB Galera Cluster 10.x (with master failover), using GTID with ClusterControl.

How to Set Up Asynchronous Replication from Galera Cluster to Standalone MySQL server with GTID

Hybrid replication, i.e. combining Galera and asynchronous MySQL replication in the same setup, became much easier since GTID got introduced in MySQL 5.6. In this blog post, we will show you how to replicate a Galera Cluster to a MySQL server with GTID, and how to failover the replication in case the master node fails.

Updated - How to Bootstrap MySQL or MariaDB Galera Cluster

Galera requires you to start a node in a cluster as a reference point, before the remaining nodes are able to join and form the cluster. This process is known as cluster bootstrap. Bootstrapping is an initial step to introduce a database node as primary component, before others see it as a reference point to sync up data.
