Hi everyone,
I have a question regarding the PXC XtraDB Cluster on Kubernetes, specifically how it relates to the Percona Operator and HAProxy.
How are the versions of XtraDB Cluster, the Operator, and HAProxy interconnected?
When I check the release notes for the Percona Operator, I see that only three tested versions of XtraDB Cluster are listed (one of them being a tech preview). However, since the auto-upgrade feature is available, does that mean the Percona XtraDB version will automatically update to the latest one available in the repository?
For HAProxy, it seems to follow the Helm chart versioning—for example, chart version 1.4 uses HAProxy 1.14 However, I can also manually choose a different version if needed.
This leaves me a bit uncertain about which versions we should install. Is there an official support matrix covering compatibility between these components? Or are the version dependencies between the Operator, HAProxy, and Percona XtraDB Cluster not as critical?
I’d appreciate any guidance or best practices on this. Thanks in advance!
