Solanica joins MariaDB Foundation as a Silver Sponsor
We are pleased to welcome Solanica, the company driving the development of OpenEverest, as a MariaDB Foundation Silver Sponsor.
OpenEverest is an open-source platform for deploying and managing databases on Kubernetes. Its recently added MariaDB support gives developers and platform teams another way to bring MariaDB into their infrastructure, with deployment, high availability, backups and recovery accessible through a common interface.
MariaDB in the Kubernetes ecosystem
For organisations running applications on Kubernetes, database support is an important part of their […]

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 […]

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 […]

MariaDB & K8s: Create a Secret and use it in 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 […]

MariaDB & K8s: Communication between containers/Deployments
In the previous blog, a background Deployment resource was created from a YAML file, consisting of a single container (MariaDB) that acts as a background container.
In this blog we are going to proceed to create the frontend container to communicate with the backend through a Service and other resources.
About Services
When an application is run through the Deployment Pods are created and destroyed dynamically. When created, they get the internal IP address in a cluster, and since they […]

Start MariaDB in K8s
This is the first in a series of blogs explaining how to use MariaDB in Kubernetes (K8s), as well as explaining some important concepts of K8s and of MariaDB.
This blog explains how to start MariaDB as a stateless application in K8s using the CLI and explores different commands you can run on your CLI.
The prerequisites are that you have installed kubectl (which will also install Docker runtime) and minikube (local K8s).
Let’s first start the minikube
The Pod […]
