Running Percona XtraDB Cluster in Kubernetes/OpenShift

Kubernetes, and its most popular distribution OpenShift, receives a lot of interest as a container orchestration platform. However, databases remain a foreign entity, primarily because of their stateful nature, since container orchestration systems prefer stateless applications. That said, there has been good progress in support for StatefulSet applications and persistent storage, to the extent that it might be already comfortable to have a production database instance running in Kubernetes. With this in mind, we’ve been looking at running Percona XtraDB Cluster in Kubernetes/OpenShift.

While there are already many examples on the Internet of how to start a single MySQL instance in Kubernetes, for serious usage we need to provide:

  • High Availability: how can we guarantee availability …

Deploying PMM on DigitalOcean

It’s very easy to install Percona Monitoring and Management (PMM) on DigitalOcean. If you’ve never used DigitalOcean before, you will find that it is user-friendly and not very expensive. For $5/month you can easily host your PMM on it, letting you monitor your simple infrastructure or try out PMM before implementing it to monitor your production environments.

Let’s prepare the DigitalOcean instance

Log in to DigitalOcean (DO) control panel and click “Create Droplet.”

Thanks to DO you can skip the boring OS setup and save time by using the Docker “One click app” in DO and the Docker image from PMM.

Note: After clicking on “Docker…” choose an instance size that accommodates your budget – PMM can run on as little as the 1GB 1vCPU instance!

Note: Scroll again!

Next step – select a nearby region …

Setting up PMM on Google Compute Engine in 15 minutes or less

In this blog post, I will show you how easy it is to set up a Percona Monitoring and Management server on Google Compute Engine from the command line.

First off you will need to have a Google account and install the Cloud SDK tool. You need to create a GCP (Google Cloud Platform) project and enable billing to proceed. This blog assumes you are able to authenticate and SSH into instances from the command line.

Here are the steps to install PMM server in Google Cloud Platform.

1) Create the Compute engine instance with the following command. The example creates an Ubuntu Xenial 16.04 LTS compute instance in the us-west1-b zone with a 100GB persistent disk. For production systems it would be best to use a 500GB disk instead (size=500GB). This should be …

Test MySQL 8.0 right in your computer

MySQL 8.0 GA is right around the corner. I don't have precise information about its release, as I don't work at Oracle. If I did, I would probably know, but I couldn't tell when the release is scheduled to appear because of company policies. I can, however, speculate and infer, based of my experience with previous releases. My personal assessment is that the release will appear before 9:00am PT on April 24, 2018. The "before" can be anything from a few minutes to one week in advance.
Then, again, it may not happen at all if someone finds an atrocious bug that needs to be fixed asap.

Either way, users are keen on testing the new release in its current state of release candidate. Here I show a few methods that allow you to have a taste of the new …

Docker, MySQL and Experience in Containers

Recently I posted a blog on my time attending a DevOps event in Toronto.  In that blog I had intended to focus on the conference and highlight some of the topics that stood out for me.  In this blog though, I wanted to share what others were doing with containers like Docker, and particularly and… Read More »

MySQL group replication: installation with Docker

Overview

MySQL Group Replication was released as GA with MySQL 5.7.17. It is essentially a plugin that, when enabled, allows users to set replication with this new way.

There has been some confusion about the stability and usability of this release. Until recently, MySQL Group Replication (MGR) was only available in the Labs, which traditionally denotes a preview or an use-at-your-own-risk feature. Several months ago we saw the release of Group Replication as a Docker image, which allowed users to deploy a peer-to-peer cluster (every node is a master.) However, about one month after such release, word came from Oracle discouraging this setup, and inviting users to use Group Replicator in …
