MySQL Router is part of InnoDB cluster, and is lightweight middleware that provides transparent routing between your application and back-end MySQL Servers. It can be used for a wide variety of use cases, such as providing high availability and scalability by effectively routing database traffic to appropriate back-end MySQL Servers. The pluggable architecture also enables developers to extend MySQL Router for custom use cases.
- MySQL Router 8.0, Release Candidate (tag:
latest,8.0,8.0.4-rc) (mysql-router/8.0/Dockerfile)
Images are updated when new MySQL Server maintenance releases and development milestones are published. Please note that non-GA releases are for preview purposes only and should not be used in production setups.
The image currently uses the following variables:
| Variable | Description |
|---|---|
| MYSQL_HOST | MySQL host to connect to |
| MYSQL_PORT | Port to use |
| MYSQL_USER | User to connect with |
| MYSQL_PASSWORD | Password to connect with |
| MYSQL_INNODB_NUM_MEMBERS | The number of cluster instances to wait for |
Running in a container requires a working InnoDB cluster. The run script waits for the given mysql host to be up, the InnoDB cluster to have MYSQL_INNODB_NUM_MEMBERS members and then uses the given server for its bootstrap mode Bootstrapping.
The image can be run via:
docker run -e MYSQL_HOST=localhost -e MYSQL_PORT=3306 -e MYSQL_USER=mysql -e MYSQL_PASSWORD=mysql -e MYSQL_INNODB_NUM_MEMBERS=3 -ti mysql-router
It can be verified by typing:
docker ps
The following output should be displayed:
