Docker master slave MySQL replication

Docker master slave mysql replication can be a bit intimidating, but the basics are actually quite easy, just a bit of a laborious work. As of this example I will use docker swarm. for that I assume you have docker already installed fresh on the machine. My example uses CentOS 7.6, but should be similar on other systems like ubuntu. Enjoy the post!

Get the mysql image:

docker pull percona:5.7

Create a few dirs to hold the structure:

Two separate folders for master and slave.
The cnf directory has the configuration files for mysql
The data directory has the volume of mysql structural data.
The folders called mysql, performance schema and sys should NOT be created. those are done by MySQL server on start.

Good day, today I am going to talk about Fedora Linux, I can not say I am a great Fedora expert. I have been following the project for a while. but I have decided to install the workstation just a few days ago. My main experience is with Debian based distros, Mint, Ubuntu. I kind of know the system, I have been working with it for around 8 years as developer, network administrator, consultant and enthusiastic. I love Linux, but redhat was never an option for me, and it’s not an option at least for server. I am going to talk about Fedora, the workstation. Fedora is a Red hat based system, well actually fedora is the testing red hat, and in any case they are the same family. I my case this is what happened.

I have a laptop ASUS X750J; it’s a very good laptop for my personal needs. It has a core i7, 6Gb or RAM, 750 HDD. The thing is, even with my experience I never managed to configure properly any of my favorite Operating Systems; as I said Debian, Mint or Ubuntu. So I started looking around for options, I decided to try Fedora 21. The experience is amazing, everything worked from the start.I did not even had to modify a single configuration.
