This image runs mongodump to backup data using cronjob to folder /mongo-backup
For a prebuilt version of this Docker image, you can use mine: firasdotcom/mongodb-backerup
docker run -d --name mongodb-backerup \
--env MONGODB_HOST=mongodb.host \
--env MONGODB_PORT=27017 \
--env MONGODB_USER=admin \
--env MONGODB_PASS=password \
--volume host.folder:/mongo-backup \
mongodb-backerup
If you link mongodb-backerup
to a mongodb container(e.g. mongodb
) with an alias named mongodb, this image will try to auto load the host
, port
, user
, pass
if possible.
For example docker run -d -p 27017:27017 -p 28017:28017 -e MONGODB_PASS="mypass" --name mongodb mongodb docker run -d --link mongodb:mongodb -v host.folder:/mongo-backup mongodb-backerup
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
INIT_BACKUP if set, create a backup when the container launched
See the list of backups, you can run:
docker exec mongodb-backerup ls /mongo-backup
To restore database from a certain backup, simply run:
docker exec mongodb-backerup /restore.sh /mongo-backup/backup_name
