Backup MongoDB
This image runs mongodump to backup data using cronjob to folder /backup
docker run -d \
--env MONGODB_HOST=mongodb.host \
--env MONGODB_PORT=27017 \
--env MONGODB_USER=admin \
--env MONGODB_PASS=password \
--volume host.folder:/backup
tutum/mongodb-backup
Moreover, if you link tutum/mongodb-backup
to a mongodb container(e.g. tutum/mongodb
) with an alias named mongodb, this image will try to auto load the host
, port
, user
, pass
if possible.
docker run -d -p 27017:27017 -p 28017:28017 -e MONGODB_PASS="mypass" --name mongodb tutum/mongodb
docker run -d --link mongodb:mongodb -v host.folder:/backup tutum/mongodb-backup
MONGODB_HOST the host/ip of your mongodb database
MONGODB_PORT the port number of your mongodb database
MONGODB_USER the username of your mongodb database. If MONGODB_USER is empty while MONGODB_PASS is not, the image will use admin as the default username
MONGODB_PASS the password of your mongodb database
MONGODB_DB the database name to dump. If not specified, it will dump all the databases
EXTRA_OPTS the extra options to pass to mongodump command
CRON_TIME the interval of cron job to run mongodump. `0 0 * * *` by default, which is every day at 00:00
MAX_BACKUPS the number of backups to keep. When reaching the limit, the old backup will be discarded. No limit, by default

See the list of backups, you can run:
