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.

A few weeks ago we hosted a webinar together with Acronis and CPanel on security and backup best practices as both provide software in this space. Acronis develops Cyber Security cloud based software particularly specializing in backup and disaster recovery for other service providers. CPanel in turn helps those service providers to enable their customers to administer their systems via a fully fledged dashboard. The webinar was a follow-up on another join presentation at CloudFest. The webinar presented quite a number of good ideas and I highly recommend you watch it.

Please join MariaDB Foundation in giving a bit of financial recognition to Olivier Bertrand, the developer behind the CONNECT Storage Engine! We will match your contribution up to a total of 5.000 €, on top of the 5.000 € that we have already allocated 5000 € for Olivier Bertrand’s Lifetime MariaDB Contribution Award.
What is CONNECT?
Olivier Bertrand is an unsung hero. He is the original contributor and still the main developer behind the CONNECT Storage Engine, which – much as its descriptive name indicates – enables MariaDB Server users to connect to a variety of databases other than MariaDB Server itself.

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 triggered it now was playing around with Python and the relative ease of transforming one format to another, including PDF.

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.

In the previous blog we created a stateless application, deployed it with K8s resource Deployment, and exposed the root password, which, regarding security, is of course not recommended. K8s allows one to hide confidential data using specific K8s resources.
Let’s see how to use Secrets in K8s.
Secrets in K8s
In order to save confidential data one can use a K8s resource called Secret.
One can create Secret from the CLI by running kubectl create secret.
Here we will use two methods to create the secret.
