Trying out MySQL in Docker Swarm Mode
Employee_Team +1 Vote Up -0Vote Down

Orchestration tools are often used when scaling out an application stack. In a Docker environment, tools like Kubernetes, Mesos and Docker Swarm have typically been used for this purpose. Docker has brought significant updates to their orchestration offering with their latest release. In this blog post, we’ll give a contextual overview of the orchestration features offered in […]

Docker Images for MySQL Group Replication 5.7.14
+0 Vote Up -0Vote Down

In this post, I will point you to Docker images for MySQL Group Replication testing.

There is a new release of MySQL Group Replication plugin for MySQL 5.7.14. It’s a “beta” plugin and it is probably the last (or at lease one of the final pre-release packages) before Group Replication goes GA (during Oracle OpenWorld 2016, in our best guess).

Since it is close to GA, it would be great to get a better understanding of this new technology. Unfortunately, MySQL Group Replication installation process isn’t very user-friendly. …

In this post, I’ll review Docker multi-host network performance.

In a past post, I tested Docker network. The MySQL Server team provided their own results, which are in line with my observations.

For this set of tests, I wanted to focus more on Docker networking using multiple hosts. Mostly because when …

Docker automatic MySQL slave propagation
+0 Vote Up -0Vote Down

In this post, we’ll discuss Docker automatic MySQL slave propagation for help with scaling.

In my previous posts on the Docker environment, I covered Percona XtraDB Cluster. Percona XtraDB Cluster can automatically scale by conveniently adding new nodes using the highly automated State Snapshot Transfer. State Snapshot Transfer allows a new node to copy data from an existing node (I still want to see how this is possible with MySQL Group Replication).

This is not the case with regular MySQL Replication. With MySQL Replication, …

systemd: a revolution gets used to itself
+0 Vote Up -0Vote Down

New versions of systemd (like in Ubuntu 16.04) are able to configure pid Cgroups (ulimit -u via Cgroups) using TasksMax.

Check the commit implementing TaksMax.

Author: Lennart Poettering <lennart@poettering.net>
Date:   Fri Nov 13 19:28:32 2015 +0100

    core: enable TasksMax= for all services by default, and set it to 512

    Also, enable TasksAccounting= for all services by default, too.

    See:

    http://lists.freedesktop.org/archives/systemd-devel/2015-November/035006.html

But not we’ve got silly defaults:

$ systemctl show -p TasksMax docker
TasksMax=512

Quick start MySQL testing using Docker (on a Mac!)
+0 Vote Up -0Vote Down

In this post, we’ll discuss how you can quick start MySQL testing using Docker, specifically in a Mac environment.

Like a lot of people, I’m hearing a lot about Docker and it’s got me curious. The Docker ecosystem seems to be moving quickly, however, and simple “getting started” or “how-to” type articles that are easy to find for well-established technologies seem to be out-of-date or non-existent for Docker. I’ve been playing with Docker on Mac for a bit, but it is definitely a second-class citizen in the Docker world. …
