jamiejackson/mariadb-replication repository overview

Note: While anybody can use this (according to any potential upstream licenses), it's not supported for public use.

Docker images to support implicit mysql replication support.

Features:

• based on official MariaDB images
• when you start the slave, it starts with replication started,
• no manual sync (mysqldump) is needed,
• slave fails to start if replication not healthy

Additional environment variables:

• REPLICATION_USER [default: replication]
• REPLICATION_PASSWORD [default: replication_pass]
• REPLICATION_HEALTH_GRACE_PERIOD [default: 3]
• REPLICATION_HEALTH_TIMEOUT [default: 10]
• MASTER_PORT [default: 3306]
• MASTER_HOST [default: master]

⁠Docker Compose

docker-compose up

⁠Convenience Functions

These are a quick way to try this image with a master and a pair of slaves. (As the docker-compose.yml is currently configured, none of them persist data.)

• bin/start.sh - Start the services.
• bin/test.sh - Test replication.
• bin/kill.sh - Destroy all traces of the running services.

⁠Docker Run

⁠Start master

docker run -d \
  --name mysql_master \
  -e MYSQL_ALLOW_EMPTY_PASSWORD=1 \
  jamiejackson/mariadb-replication:latest

⁠Start slave

docker run -d \
  --name mysql_slave \
  -e MYSQL_ALLOW_EMPTY_PASSWORD=1 \
  --link mysql_master:master \
  jamiejackson/mariadb-replication:latest

⁠Test the replication

cat 02-master-database.sql | docker exec -i mysql_master mysql
docker exec -it mysql_slave mysql -e 'select * from test.test'
