Measuring Docker IO overhead
+0 Vote Up -0Vote Down

This will be another post on using Percona Server via a Docker image. I want to follow up on my previous post regarding CPU/Network overhead in Docker “Measuring Percona Server Docker CPU/network overhead” by measuring  if there is any docker IO overhead on operations.

After running several tests, it appears (spoiler alert) that there is no Docker IO overhead. I still think it is useful to understand the …

Measuring Percona Server Docker CPU/network overhead
+0 Vote Up -0Vote Down

Now that we have our Percona Server Docker images, I wanted to measure the performance overhead when we run the database in the container. Since Docker promises to use a lightweight container, in theory there should be very light overhead. We need to verify that claim, however. In this post I will show the numbers for CPU and network intensive workloads, and later I will take a look …

Experimental Percona Docker images for Percona Server
+0 Vote Up -0Vote Down

Docker is incredibly popular tool for deploying software, so we decided to provide a Percona Docker image for both Percona Server MySQL and Percona Server for MongoDB.

We want to create an easy way to try our products.

There are actually some images available from https://hub.docker.com/_/percona/, but these images are provided by Docker itself, not from Percona.

In our images, we provide all the varieties of storage engines …

A safer MySQL box in Docker
+0 Vote Up -0Vote Down

The MySQL team has been maintaining a MySQL image on Docker. They have been listening to requests from the community and reacting quickly. So far, they have fixed two bugs that I reported and introduced a feature request that I suggested to make the server more secure.

Thanks, folks!

My latest request was about password management in a MySQL container. I have mentioned in previous posts the compatibility problems introduced by MySQL 5.7 security enhancements. Let me recap the main issues here:

MySQL in docker or native – performance benchmarks
+1 Vote Up -0Vote Down

Back in October I have write about possible ways of running multiple MySQL instances on the same hardware. As the months passing by, the project of splitting our database schemas into standalone instances is closing in, so I started to check the different ways. I started with docker, because we’ll use containers anyway with the applications, and […]

Proposals Percona Live 2016

Ahoi, I made three proposals for Percona Live. (Even I know being a lonely (sniff) freelancer with no backup). At least I'm for sure an early adopter about the three topics I submitted and know for sure what I'm talking about *g*   

Even being Puppet certified. Ansible is my love. Never been that fast in doing automation \o/

This is a quick post only indirectly related to the series of articles about Docker that I have written recently.

Yesterday I was giving a presentation about Docker in Buenos Aires, and as usual I included a long live demo. Almost all went as expected. There was one …

After seeing the basics of deploying a MySQL server in Docker, in this article we will lay the foundations to customising a node and eventually using more than one server, so that we can cover replication in the next one.
Enabling GTID: the dangerous approach.To enable GTID, you need to set five variables in the database server:
