This repo provides a minimal config for setting up Maxwell to read the MySQL binlog.
This is not intended in any way to be put into production. Instead it's a starting point for understanding how to configure Maxwell and an easy way of testing configuration changes.
You'll first need to install Docker if you haven't already.
Docker Compose is used to set up three containers, one acting as the master database instance, one as a slave and the third running Maxwell connected to the slave.
To build the containers for the first time, run:
docker-compose build
You can then start the containers by running:
docker-compose up
And stop them by running:
docker-compose down
You can open a mysql client on the master using:
docker-compose exec master mysql --user root -p
And similarly on the slave with:
docker-compose exec slave mysql --user root -p
It'll help to have some familiarity with Docker.
The docker-compose.yml file configures three services, master, slave and
maxwell. The containers share a network called db so that they can
communicate.
To understand how the containers are configured, look at the files in the
slave and maxwell directories. There are comments in each file to explain
what's going on.
