The MariaDB Foundation relies on public mirrors to distribute binaries and packages to the world. An overview of the full list can be seen at https://mirmon.mariadb.org. If you would like to volunteer to become a mirror, take a look at https://mariadb.com/kb/en/mirror-sites-for-mariadb/.
Our download page already automatically suggests one of those mirrors for you to download our binaries. Same goes for the repository configuration tool; see https://mariadb.org/download.
The purpose of this blog post is to present you a new system that we have been testing since December 2021 and that we believe is now ready for public adoption.

Well over two years ago was the last time the MariaDB Foundation staff had met. That was at FOSDEM, in February 2020. Thus, no big surprise, one of our topmost goals for 2022 was to have a staff meeting, face to face. It’s about time to oil the social relationships, to work together without connection issues, to be reminded of how work and life can be in a world where Covid isn’t the top issue.
In other words: we planned a post-pandemic Staff Meeting.
The outcome was different.
Choosing the venue
But let us start from the beginning, from the original euforia.

Yes, we are hiring!
And we are hiring for quite an interesting position: As a senior developer of MariaDB Server, with merging community code contributions as a main task.
A demanding job
This is a very demanding job. The MariaDB Server code base is large and complex, and being a good C / C++ developer is only the starting point for being able to contribute to it. You also need to understand databases, and the existing codebase architecture.
A demanding code base
The existing codebase is demanding. Depending on how you look at it, it’s either very efficient (if you know it well), or it has many dependencies (if you don’t).

In this blog we are going to demonstrate how to replicate a MariaDB database that runs in a Docker container (let’s call it primary) to one or more MariaDB servers that run in a Docker container (let’s call them replicas) using binary logging, a method that creates binary log files and an index that contains the record of all changes to the database (both data and structure). You can find an overview of how replication works here and you can find how to setup replication here. An example can be found in this GitHub script.

The lifeblood of MariaDB Foundation is contributions. Our trinity consists of the fundamental values of Adoption (of MariaDB Server), Openness (of the MariaDB Server codebase), and Continuity (of our operations and activities), all of which are centered around MariaDB Server. We rely on our financial sponsors to finance our activities, but the financial value of the code contributions we receive outshines the total sponsorship payments. That has been the case every year since MariaDB Server was launched.
Giving recognition to code contributions
The MariaDB Foundation has not given proper recognition to this fact, of the value of our contributions.

Our Board Meeting in April 2022 elected two seasoned new voting board members. One of them is Xiang Peng (Sean), Director, RDS Open Source Databases at Alibaba Cloud. I had the pleasure of having a Fireside Chat with him, which we recorded and put up on YouTube. Read on for his recommendations for MariaDB Foundation in China.
A Man With the Right CV for MariaDB Foundation
Sean, as he calls himself for those of us who have problems remembering, reading or writing his real name 彭祥, is a great resource for MariaDB Foundation.

In the previous blog we created a stateless application, deployed with K8s resource Deployment, which allows one to replicate the application, but where data is lost when Pods are restarted, meaning there were no data consistency. In the same blog we used PersistentVolumeClaim for dynamic provisioning of PersistentVolume, but we used Deployment, meant for stateless application, and this way is *not recommended* for statefulset application where each replica should have its own persistent volume. The proper way to achieve that is through the Statefulset resource and this post we will cover that.
In K8s one can create a stateful application, an application like a database, which needs to save data to persistent disk storage for use by the server/clients/other applications, to keep track of its state and to be able to replicate and be used in distributed systems.

In the previous blog, MariaDB & K8s: Create a Secret and use it in MariaDB deployment, we used the Secrets resource to hide confidential root user data, and in the blog before that in the series, MariaDB & K8s: Communication between containers/Deployments, we created 2 containers (namely MariaDB and phpmyadmin) in a Pod. That kind of deployment didn’t have any persistent volumes.
In this blog we are going to create separate Deployments for MariaDB and WordPress applications as well as a Service for both in order to connect them. Additionally we will create Volume in a Pods of a MariaDB Deployment.
