Files for Fabric POC

This directory contains tools to setup a fabric POC

- fabric.yml: docker-compose file to setup 3+ mysql nodes
- script to configure fabric nodes
- fabric.cfg.t: fabric template used by
- my-gtid.cnf: fabric requires GTID configuration

IMPORTANT: if you can't resolve containers' hostnames you should take care
of setting IPs instead of hostnames

    #docker inspect -f '{{.Name}} {{.NetworkSettings.IPAddress}}' $(docker ps -q)


Create 4 database hosts:

#export COMPOSE_FILE=fabric.yml
#docker-compose scale master=1 slave=2 fabric=1
#docker exec fabric python /code/ setup localhost m.docker s-1.docker s-2.docker
#docker exec -ti fabric /bin/bash

mysqlfabric manage setup --param=storage.user=fabric
mysqlfabric manage start --daemonize

mysqlfabric manage ping

Create the "ha" group and add a master and a slave.

mysqlfabric group create ha
mysqlfabric group add ha m.docker:3306
mysqlfabric group add ha s-1.docker:3306


#mysqlfabric group lookup_servers ha
mysqlfabric group health ha

Add a new node

Let's add a new node simulating that not enough binlogs are present

#mysql -uroot -proot -h m.docker -e 'purge logs;'

Now provision a new node via docker-compose:

#docker-compose scale slave=3

And clone the master databases on the new node.

#mysqlfabric server clone ha s-4.docker 
#mysqlfabric group add ha s-4.docker:3306
