mongodb-backup-s3

This image runs mongodump to backup data using cronjob to an s3 bucket

Usage:

docker run -d \
  --env AWS_ACCESS_KEY_ID=awsaccesskeyid \
  --env AWS_SECRET_ACCESS_KEY=awssecretaccesskey \
  --env BUCKET=s3bucket
  --env MONGODB_HOST=mongodb.host \
  --env MONGODB_PORT=27017 \
  --env MONGODB_USER=admin \
  --env MONGODB_PASS=password \
  halvves/mongodb-backup-s3

If you link halvves/mongodb-backup-s3 to a mongodb container with an alias named mongodb, this image will try to auto load the host, port, user, pass if possible. Like this:

docker run -d \
  --env AWS_ACCESS_KEY_ID=myaccesskeyid \
  --env AWS_SECRET_ACCESS_KEY=mysecretaccesskey \
  --env BUCKET=mybucketname \
  --env BACKUP_FOLDER=a/sub/folder/path/ \
  --env INIT_BACKUP=true \
  --link my_mongo_db:mongodb \
  halvves/mongodb-backup-s3

Add to a docker-compose.yml to enhance your robotic army:

For automated backups

mongodbbackup:
  image: 'halvves/mongodb-backup-s3:latest'
  links:
    - mongodb
  environment:
    - AWS_ACCESS_KEY_ID=myaccesskeyid
    - AWS_SECRET_ACCESS_KEY=mysecretaccesskey
    - BUCKET=my-s3-bucket
    - BACKUP_FOLDER=prod/db/
  restart: always

Or use INIT_RESTORE with DISABLE_CRON for seeding/restoring/starting a db (great for a fresh instance or a dev machine)

mongodbbackup:
  image: 'halvves/mongodb-backup-s3:latest'

    - BACKUP_FOLDER=prod/db/
    - INIT_RESTORE=true
    - DISABLE_CRON=true

AWS_ACCESS_KEY_ID - your aws access key id (for your s3 bucket)

AWS_SECRET_ACCESS_KEY: - your aws secret access key (for your s3 bucket)

BACKUP_FOLDER: - name of folder or path to put backups (eg myapp/db_backups/). defaults to root of bucket.

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

Restore from a backup

To see the list of backups, you can run:

docker exec mongodb-backup-s3 /listbackups.sh

To restore database from a certain backup, simply run (pass in just the timestamp part of the filename):
