mongodb-backup

This image runs mongodump to backup data using cronjob to folder /backup

Usage:

docker run -d \
    --env MONGODB_HOST=mongodb.host \
    --env MONGODB_PORT=27017 \
    --env MONGODB_USER=admin \
    --env MONGODB_PASS=password \
    --volume host.folder:/backup
    tsangste/mongodb-backup

Moreover, if you link tsangste/mongodb-backup to a mongodb container(e.g. official mongodb mongo:latest) 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 mongo:latest
docker run -d --link mongodb:mongodb -v host.folder:/backup --name mongodb-backup tsangste/mongodb-backup

Parameters

MONGODB_HOST    the host/ip of your mongodb database
MONGODB_PORT    the port number of your mongodb database
