Popular Docker Images for MySQL and MariaDB Server

There are many Docker images for MySQL and MariaDB, but which one should you use? This blog post lists the most popular Docker images that can be found on Docker Hub, the world's largest library and community for container images.

How to Deploy PostgreSQL to a Docker Container Using ClusterControl

Deploying a single PostgreSQL instance on Docker is fairly easy, but deploying a replication cluster requires a bit more work. In this blog, we’ll see how to deploy PostgreSQL on Docker and how we can make it easier to configure a primary-standby replication setup with ClusterControl.

Monitoring & Ops Management of MySQL 8.0 with ClusterControl

MySQL 8.0 is a big step forward in terms of data consistency, developer features, performance and availability. MySQL 8.0 shortens the gap between proprietary databases and open source world, making the migration decision much easier to take.

But how can you manage it, along with other relational open source databases? In this blog post, we look at the challenges of operating a MySQL 8.0 database, and see how important tasks like monitoring, alerting, backups and failover can be handled in an automated way.

How to Run and Configure ProxySQL 2.0 for MySQL Galera Cluster on Docker

ProxySQL 2.0 has become GA and it comes with new exciting features such as GTID consistent reads, frontend SSL, Galera and MySQL Group Replication native support. This blog post shows how to run the new ProxySQL 2.x for Galera Cluster on Docker container, which is quite a bit different as compared to ProxySQL 1.x.

Deploying MongoDB Using Docker

This blog provides an introduction to deploying MongoDB using a Docker container. We will look at some important concepts like volume mapping and connecting to a MongoDB container from another container using links.

MySQL on Docker: Multiple Delayed Replication Slaves for Disaster Recovery with Low RTO

A delayed replication slave is useful in recovering from accidental data deletion. But how long should the delay be? Too short delay might not be enough for you to get to a terminal and stop an offending query. Too long delay means a long recovery time when catching up.

This blog post shows how to deploy multiple MySQL delayed slaves on one single physical host with Docker, and shows some of the recovery scenarios.

MySQL on Docker: Running ProxySQL as Kubernetes Service

When your application containers are orchestrated and managed by Kubernetes, you might want to use ProxySQL in front of your database servers. In this post, we’ll show you how to configure ProxySQL as a Kubernetes service.

MySQL on Docker: Running ProxySQL as a Helper Container on Kubernetes

When your application containers are orchestrated and managed by Kubernetes, you might want to use ProxySQL to better take advantage of your distributed database service running on replication or Galera. In this post, we are going to cover how to run ProxySQL on Kubernetes as a helper container in a pod.

MySQL on Docker: How to Monitor MySQL Containers with Prometheus - Part 1 - Deployment on Standalone and Swarm

Prometheus is an open-source software for monitoring and alerting, it depends on exporters to ‘scrape’ information from e.g., MySQL running on Docker. In this blog, we’ll see how to deploy the database as well as the monitoring stack with Prometheus and its components. We’ll do this for both MySQL running on standalone Docker containers as well as a Galera Cluster running on Docker Swarm.

Using Kubernetes to Deploy PostgreSQL

This blog provides steps on how to run a PostgreSQL database on a Kubernetes cluster using Docker containerization.
