MySQL on Docker: Running Galera Cluster in Production with ClusterControl on Kubernetes

In our previous posts, we showed how one can run Galera Cluster on Kubernetes. This blog post covers how ClusterControl being part of the stack helps in running your Galera Cluster in production environment.

Docker: All the Severalnines Resources

Severalnines was an early believer in Docker and have developed many exciting resources and tutorials on how to utilize Docker for open source database management.

MySQL on Docker: Running Galera Cluster on Kubernetes

In our previous posts, we showed how one can run Galera Cluster on Docker Swarm, and discussed some of the limitations with regards to production environments. Kubernetes is widely used as orchestration tool, and we’ll see whether we can leverage it to achieve production-grade Galera Cluster on Docker.

Using the Galera Replication Window advisor to avoid SST

In Galera Cluster, the gcache provides incremental state transfers by sending transactions to joining nodes. But if the gcache file is too small, this may cause full state snapshot transfers. The Galera replication window advisor will continuously review if your gcache size is large enough.

MySQL on Docker: Swarm Mode Limitations for Galera Cluster in Production Setups

This blog post explains some of the Docker Swarm Mode limitations in handling Galera Cluster natively in production environments.

How to use s9s -The Command Line Interface to ClusterControl

s9s is our official command line tool to interact with ClusterControl. We’re pretty excited about this, as we believe its ease of use and script-ability will make our users even more productive. Let’s have a look at how to use it.

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.
