MySQL Support Engineer's Chronicles, Issue #5 [60957]
By Valeriy Kravchuk

Valeriy blogs, "A lot of time passed since my previous post in this series. I was busy with work, participating in FOSDEM, blogging about profilers and sharing various lists of MySQL bugs. But I do not plan to stop writing about my usual weeks of doing support engineer's job. So, time for the next post in this series, based on my random notes taken during the week here and there.

This week started for me with checking recent MySQL bug reports (actually I do it every day). I noted recent report by Roel, Bug #85065. Unfortunately it was quickly marked as "Won't fix", and I tend to agree with Laurynas Biveinis that this was probably a wrong decision..."

MySQL on Docker: Composing the Stack [60735]
By Severalnines, February 15th, 2017

Severalnines blogs, "Docker 1.13 introduces a long-awaited feature called compose-file support, which allow us to define our containers with a nice simple config file instead of a single long command. If you have a look at our previous 'MySQL on Docker' blog posts, we used multiple long command lines to run containers and services. By using compose-file, containers are easily specified for deployment. This reduces the risk for human error as you do not have to remember long commands with multiple parameters.

In this blog post, we'll show you how to use compose-file by using simple examples around MySQL deployments. We assume you have Docker Engine 1.13 installed on 3 physical hosts and Swarm mode is configured on all hosts..."

MySQL allows you to flush logs using flush logs command, next 'How to rotate and clean up old MySQL logs?' ..."
