After publishing the Docker container for RonDB I got a suggestion to simplify it further by using Docker Compose. After a quick learning using Google I came up with a Docker Compose configuration file that will start the entire RonDB cluster and stop it using a single command.
First of all I had to consider networking. I decided that using an external network was the best solution. This makes it easy to launch an application that uses RonDB as a back-end database. Thus I presume that an external network has been created with the following command before using Docker Compose to start RonDB:
docker network create mynet --subnet=192.168.0.0/16
The docker-compose.yml is available on GitHub at
In the file rondb/21.04/docker-compose.yml for RonDB 21.04 and in rondb/21.10/docker-compose.yml for RonDB 21.10. Link to docker-compose.yml
To start a RonDB cluster now run this command from a directory where you have placed docker-compose.yml.
docker-compose up -d
After about 1 minute the cluster should be up and running and you can access it using:
docker exec -it compose_test_my1_1 mysql -uroot -p
The MySQL Server is available at port 3306 on IP 192.168.0.10 using the mynet subnet
When you want to stop the RonDB cluster use the command:
Docker Compose creates normal Docker containers that can be viewed using docker ps and docker logs commands as usual.
