rethinkdb-docker-cluster
For auto-build image, head over to docker hub: https://hub.docker.com/r/kallqvist/rethinkdb-cluster/
A docker image to make RethinkDb clustering a bit easier and more container friendly. This image is built on top of rethinkdb:latest and adds a docker-entrypoint.sh that dynamically tries to set canonical IP and join IP based on docker links and hostnames.
Basic usage is either (only for DNS-based service discovery):
- Start one container and set environment variable "JOIN" to a hostname able to reach the container's scaled nodes (e.g usually the container name)
- Simply scale this service to add more nodes
or:
- Manually start nodes as you wish
- Add them to cluster by setting their environment variable "JOIN" to either hostname or IP of an already running node.
Check https://github.com/kallqvist/rethinkdb-docker-cluster/blob/master/docker-compose.yml for more information.
Container data is written to /data, each container must have a unique storage path if host bind mounts are used to not risk data corruption.
