Managing MySQL Configurations with the PXC Kubernetes Operator V1.10.0 Part 3: Conclusion

In part one and part two of this series, we introduced the different ways to manage MySQL configurations and precedence when using the Percona XtraDB Cluster (PXC) object and ConfigMap. In this post, we will see the precedence when secrets are used for MySQL configurations in Percona Operator for MySQL based on Percona XtraDB Cluster.

CASE-4: Secret with name cluster1-pxc and ConfigMap with name cluster1-pxc but without configuration in PXC object

When the MySQL configuration is present in the ConfigMap and secret but not in the PXC …

Managing MySQL Configurations with the PXC Kubernetes Operator V1.10.0 Part 2: Walkthrough

In part one of this series, we introduced the different ways to manage MySQL configurations. In this post, we will walk through different possibilities and the changes happening while modifying MySQL configurations with the operator.

Percona Distribution for MySQL Operator based on Percona XtraDB Cluster (PXC) provides three ways for managing MySQL, but the question is, what is the precedence among options? We will walk through several cases of using MySQL configs. For the sake of simplicity, we will play with the values of the Galera cache to see the effects.

Exploring MySQL on Kubernetes with Minkube

In this blog post, I will show how to install the MySQL-compatible Percona XtraDB Cluster (PXC) Operator on Minikube as well as perform some basic actions.   I am by no means a Kubernetes expert and this blog post is the result of my explorations preparing for a local MySQL Meetup, so if you have some comments or suggestions on how to do things better, please comment away!

For my experiments, I used Minikube version 1.26 with the docker driver in the most basic installation on Ubuntu 22.04 LTS, though it should work with other combinations, too. You also can find the official “Running Percona XtraDB Cluster on Minikube” documentation …

Percona Operator for MySQL Supports Group Replication

There are two Operators at Percona to deploy MySQL on Kubernetes:

We wrote a blog post in the past explaining the thought process and reasoning behind creating the new Operator for MySQL. The goal for us is to provide production-grade solutions to run MySQL in Kubernetes and support various replication configurations:

  • Synchronous replication

Installing MySQL InnoDB Cluster in OKE using a MySQL Operator

During previous months, I’ve had some time to satisfy my curiosity about databases in containers and I started to test a little bit MySQL in Kubernetes.
This is how it all began…

In January I had the chance to be trained on Kubernetes attending the Docker and Kubernetes essentials Workshop of dbi services. So I decided to prepare a session on this topic at our internal dbi xChange event. And as if by magic, at the same time, a customer asked for our support to migrate a MySQL database to their Kubernetes cluster.

In general, I would like to raise two points before going into …

Expose Databases on Kubernetes with Ingress

Ingress is a resource that is commonly used to expose HTTP(s) services outside of Kubernetes. To have ingress support, you will need an Ingress Controller, which in a nutshell is a proxy. SREs and DevOps love ingress as it provides developers with a self-service to expose their applications. Developers love it as it is simple to use, but at the same time quite flexible.

High-level ingress design looks like this: 

  1. Users connect through a single Load Balancer or other Kubernetes service
  2. Traffic is routed through Ingress Pod (or Pods for high availability)
    • There are multiple flavors of Ingress Controllers. Some use nginx, some envoy, or other proxies. See a curated list of Ingress Controllers here.
  3. Based on HTTP headers traffic is routed …

Face to Face with Semi-Synchronous Replication

Last month I performed a review of the Percona Operator for MySQL Server which is still Alpha.  That operator is based on Percona Server for MySQL and uses standard asynchronous replication, with the option to activate semi-synchronous replication to gain higher levels of data consistency between nodes. 

The whole solution is composed as:

Additionally, Orchestrator (https://github.com/openark/orchestrator) is used to manage the topology and the settings to enable on the replica nodes, the semi-synchronous flag if required. While we have not too much to say when using standard Asynchronous replication, I want to write a few words on the needs …
