MariaDB & K8s: How to replicate MariaDB in K8s
In the previous blog we have seen how to create a statefulset MariaDB application. Also, we learned how replication works in MariaDB in this blog. Now, we will try to create a replicated statefulset application. As good references for creating this blog, I would like to give credit to the Kubernetes documentation as well as an example from Alibaba Cloud.
Configure replication
To replicate a MariaDB application we are going to create a statefulset that will consist of a single […]

A mirror manager system to simplify the distribution of MariaDB binaries and packages
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’re hiring: Senior MariaDB Developer / Code Reviewers
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 […]

MariaDB replication using containers
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 […]

MariaDB Server Documentation as PDF
MariaDB Server Documentation is now released as a single PDF file, browsable offline. Download the over 3000 pages and check it out!
Better late than never
Some things take long! In 2014, there was a request on Jira for delivering the MariaDB Server Knowledgebase in one PDF file. That’s over seven years ago. MDEV-6881, you see it in the number already – we are now at well beyond MDEV-28000.
The request has always been in the back of our heads. What […]

Create statefulset MariaDB application in K8s
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 […]

MariaDB & K8s: Deploy MariaDB and WordPress using Persistent Volumes
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 […]
