Everyone knows those situations where there is a task that you need to do and you want to do, but you just don’t come around to actually doing it. Well, for me, this new release was such a task.

Early in 2017, I released the first version of puppet-proxysql on GitHub. It was my first puppet-module release and I was quite proud of it. I had implemented types and providers for managing the ProxySQL resources such as mysql_user, mysql_servers, etc…

At Config Management Camp Gent (February 2017) I met Vox Pupuli, who is the group that forms the puppet-user-community. They picked up the responsibility of taking ownership of well-known modules that are left unmaintained or abandoned and/or modules that only had a single maintainer. The puppet-proxysql module was kind of the latter. Additionally, they …

It’s 2018. Maybe now is the time to start migrating your network to IPv6, and your database infrastructure is a great place to start. Unfortunately, many legacy applications don’t offer the option to connect to MySQL directly over IPv6 (sometimes even if passing a hostname). We can work around this by using ProxySQL’s IPv6 support which was added in version 1.3. This will allow us to proxy incoming IPv4 connections to IPv6-only database servers.

Note that by default ProxySQL only listens on IPv4. We don’t recommended changing that until this bug is resolved. The bug causes ProxySQL to segfault frequently if listening on IPv6.

In this example I’ll use centos7-pxc57-1 as my database server. It’s running …

Kubernetes, and its most popular distribution OpenShift, receives a lot of interest as a container orchestration platform. However, databases remain a foreign entity, primarily because of their stateful nature, since container orchestration systems prefer stateless applications. That said, there has been good progress in support for StatefulSet applications and persistent storage, to the extent that it might be already comfortable to have a production database instance running in Kubernetes. With this in mind, we’ve been looking at running Percona XtraDB Cluster in Kubernetes/OpenShift.

While there are already many examples on the Internet of how to start a single MySQL instance in Kubernetes, for serious usage we need to provide:
