Docker image that regularly backs up a rethinkdb instance into a volume

rethinkdb-backup

This image runs rethinkdb dump to backup data using cronjob to folder /backups

Usage:

docker run -d \
    --env RETHINKDB_HOST=rethinkdb.host \
    --env RETHINKDB_PORT=27017 \
    --volume host.folder:/backups
    iteam1337/rethinkdb-backup

Moreover, if you link rethinkdb-backup to a rethinkdb container(e.g. rethinkdb) with an alias named rethinkdb, this image will try to auto load the host, port if possible.

docker run -d -p 27017:27017 -p 28017:28017 -e --name rethinkdb tutum/rethinkdb
docker run -d --link rethinkdb:rethinkdb -v host.folder:/backups tutum/rethinkdb-backup
