In this post, I’ll discuss how to run Percona XtraDB Cluster in a multi-host Docker network. With our release of Percona XtraDB Cluster 5.7 beta, we’ve also decided to provide Docker images for both Percona XtraDB Cluster 5.6 and Percona XtraDB Cluster 5.7. Starting one node is very easy, and not that different from starting Percona Server […]
