Galera meets Docker Network \o/

Galera und Docker Network

Using Docker to run Galera on multiple nodes is quite a mess as described here. It is possible but no fun at all. As Docker does NATing every bidirectional setup is complicated.

Starting with Docker Network (version 1.9) you can simply span a Docker owned network (multiple of them) over multiple nodes. These networks are separated as the known bridged network Docker uses by default. It also provides a simple node/container discovery using the --name switch. Feels like a simple DNS.

Let's have a look how easy it is to deploy a Galera cluster. It is not for production. I use my own Docker image. It is just to play around.

There are our nodes:

  • Swarm1 IP=172.17.152.11

Under the hood: PinQueue, a generic content review system

People use Pinterest to discover, save and do things that inspire them. Every day, we connect millions of people to billions of Pins, and it’s our mission to present the highest quality content to Pinners. We use machine learning to filter out content that violates our policies for everything from Promoted Pins to spam, but manual moderation is still needed since algorithms can’t cover all of our sophisticated and ever-evolving content policies. Human inspection is always a valuable addition to machine learning pipelines. To facilitate the manual moderation process, we built PinQueue, a generic content review system.  

A variety of teams at Pinterest use PinQueue, including:

  • The Safety team, to review content that may go against our …
