xingjiudong/mongodump repository overview

⁠tenorok/mongodumper

Docker image with mongodump running as a cron task.

⁠Usage

Attach a target mongo container to this container and mount a volume to container /backup folder. The backups will appear in this volume as gzip-archives with names like 20170218_025718, where mask is %Y%m%d_%H%M%S.

⁠Scheduled backups
docker run -d \
    -v /path/to/my-folder:/backup \     # path to put backups
    --link my-mongo-container:mongo \   # linked container with running mongo
    tenorok/mongodumper
⁠Manual backup

To run manual backup without cron job, add no-cron parameter.

docker run --rm \
    -v /path/to/my-folder:/backup \
    --link my-mongo-container:mongo \
    tenorok/mongodumper no-cron         # manual start
⁠Restore from backup
mongorestore --gzip --archive=/path/to/my-folder/20170218_025718
⁠Option CRON_SCHEDULE

For customize backups schedule. Default schedule is 0 0 * * * — runs every day at 00:00.

Recommend useful online helper⁠ for decoding crontab.

docker run -d \
    -v /path/to/my-folder:/backup \
    --link my-mongo-container:mongo \
    -e 'CRON_SCHEDULE=0 3 */5 * *' \   # custom cron job schedule
    tenorok/mongodumper
⁠Option MONGO_DB_NAMES

For dump selective databases specify they names through space. This will create archives with names like 20170218_025718-db1 and 20170218_025718-db2 for each database from option.

Unfortunately now mongodump not providing opportunity to backups multiple databases at one time (TOOLS-22⁠, TOOLS-31⁠).

docker run -d \
    -v /path/to/my-folder:/backup \
    --link my-mongo-container:mongo \
    -e 'MONGO_DB_NAMES=db1 db2' \       # names (through space) of databases for dumping
    tenorok/mongodumper
⁠Option BACKUP_EXPIRE_DAYS

For remove unnecessary archives older than specified number of days.

docker run -d \
    -v /path/to/my-folder:/backup \
    --link my-mongo-container:mongo \
    -e 'BACKUP_EXPIRE_DAYS=30' \        # number of days for remove old backups
    tenorok/mongodumper
⁠Option BACKUP_FILE_NAME

For save backup with custom name. This option is more relevant for manual backup, because with scheduled backups file with specified name will overwritten each time.

docker run -d \
    -v /path/to/my-folder:/backup \
    --link my-mongo-container:mongo \
    -e 'BACKUP_FILE_NAME=express' \     # custom name for backup archive
    tenorok/mongodumper
⁠Option MONGO_USERNAME, MONGO_PASSWORD

If your mongodb need user and password to access, you need set them in your environment.

docker run -d \
    -v /path/to/my-folder:/backup \
    --link my-mongo-container:mongo \
    -e 'MONGO_USERNAME=root' \          # mongo -u $MONGO_USERNAME
    -e 'MONGO_PASSWORD=rootpassword' \  # mongo -p $MONGO_PASSWORD
    tenorok/mongodumper
