Running Percona XtraDB Cluster on Windows … in Docker

In this blog post, we’ll look at how to run Percona XtraDB Cluster on Windows using Docker.

This is a follow-up to my previous post on Percona XtraBackup on Windows. The fact is that with Docker you can now run a variety of software applications on Windows that previously were available only for Linux platforms.

We can run (to evaluate and for testing purposes) several nodes of Percona XtraDB Cluster on a single Windows box.

The steps for this are:

  1. Setup Docker on the Windows box.

Running Percona XtraBackup on Windows … in Docker

In this blog, we’ll look at running Percona XtraBackup on Windows via a Docker container.

The question whether Percona XtraBackup is available for Windows comes up every so often. While we are not planning to provide regular releases for Windows, I decided to share a way to run Percona XtraBackup in a Docker container (especially since Docker support for Windows has become more and more stable).

For this exercise, I created a playground Docker image: perconalab/percona-xtrabackup.

First, we need to prepare a few things to make it work:

  1. Install Docker on Windows (the current version I am running is 17.03)
  2. Enable the sharing of disk C in Docker settings
  3. Find out the IP address MySQL is running on …

Get Started Running Laravel in a Docker Container

Laravel and Docker are two very popular tools of choice when considering building for the web. Although both of them do very different things, they can both be combined to create amazing products.

For our use case, we will be running Laravel in a Docker container. This is going to be a simple demonstration on how to use both products to create real-life applications. Nothing heavy.

While this article is made to cater for everyone who will be reading it, the article assumes you already have a working basic knowledge of both Docker and Laravel.

Prerequisites

Before you start, you need to have some certain prerequisites in place:

  • Local machine running the latest version of Docker, v1.13.1 at the time of writing this article.
  • Local machine running the latest version of …

How to run integration tests at warp speed using Docker and tmpfs

Introduction As previously explained, you can run database integration tests 20 times faster! The trick is to map the data directory in memory, and my previous article showed you what changes you need to do when you have a PostgreSQL or MySQL instance on your machine. In this post, I’m going to expand the original … Continue reading How to run integration tests at warp speed using Docker and tmpfs →

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 …

Testing MySQL/MariaDB/Percona versions with Docker

Giuseppe Maxia has provided some great MySQL docker images. Percona and MariaDB also provide version via Docker Hub. In an attempt to have a consistent means of launching these different images I created the following convenience functions.

  1. Install docker for your OS. See Official Docker installation instructions.
  2. Get dockerhelper.sh
  3. Run your desired variant and version.

$ wget https://raw.githubusercontent.com/ronaldbradford/mysql-docker-minimal/master/dockerhelper.sh
$ . ./dockerhelper.sh

Building RPM on Travis-CI in Docker containers

Travis-CI is a crucial component in Continuous Integration/Continuous Deployment. We use it a lot to run unit tests and building/uploading Python modules.

Recently I had to solve a problem of building RPMs on Travis-CI with Docker containers. In this post I will describe step-by-step how to do that.

We distribute our backup tool as RPM packages for CentOS 6 and 7. But Travis-CI slaves run Ubuntu trusty. In theory I could use a tool like fpm and build RPMs on Ubuntu (never tried that, but should be possible). However I like to have a .spec file. It gives you full flexibility on how RPM behaves and it’s easier to maintain it.

Travis-CI supports Docker containers, so I decided to go that way.

At high level the process is following. A Travis-CI slave starts a docker daemon. A …

Is Docker Good for Your Database?

This blog post reviews the appropriateness of Docker and other container solutions for your database environment.

A few weeks back, I wrote a fairly high-level blog post about containers. It covered what you should consider when thinking about using Docker, rkt, LXC, etc. I hope you’ve taken the chance to give it a quick read. It’s a good way to understand some of the disciplines you need to consider before moving to a new technology. However, it sparked a conversation in our Solutions Engineering team. Hopefully, the same one that you’re having in your organization: should customers run their database in containers? …

Dockerizing MySQL at Uber Engineering

In this article, we take a look at Schemadock, Uber Engineering's tooling solution for managing our increasing number of MySQL clusters.

The post Dockerizing MySQL at Uber Engineering appeared first on Uber Engineering Blog.

Three Things to Consider When Thinking About Containers

Containers like Docker and Rocket are getting more popular every day. In my conversations with customers, they consistently ask what containers are and how they can use them in their environment. If you’re as curious as most people, read on. . .

How did this happen?

From what I understand, containers grew out of Google’s (and others’) need for massive horizontal scale. Now, this is hardly a unique problem. At the time there were several different solutions out there that could help deploy and orchestrate the applications and infrastructure necessary to scale — namely virtual machines (VMs) and their orchestration services (like Vmware’s vCenter). At the uber-massive scale that companies like Google were pushing, however, server virtualization had some serious drawbacks. Enter containers. . .

What is a container?

Essentially, the main difference between a container and a virtual …
