docker-mongodump

Docker image with mongodump running as a cron task

Getting Started

Make sure the prerequisites are followed, and the container will be able to run standalone.

Prerequisites

Docker

curl -fsSL get.docker.com -o get-docker.sh
sh get-docker.sh

MongoDB

docker run 27017:27017 mongo

Installing

Build the app container image locally:

docker build --rm=false -t twnel/<my_image_name> .

Running the tests

docker exec -ti twnel/<my_image_name> bash -c 'sh backup.sh'

Deployment

Attach a target mongo container to this container and mount a volume to container's /data folder. Backups will appear in this volume. Optionally set up cron job schedule (default is 0 1 * * * - runs every day at 1:00 am).

docker run -d \
    -v /path/to/target/folder:/backup \ # where to put backups
    -e 'CRON_SCHEDULE=0 1 * * *' \      # cron job schedule
    --link my-mongo-container:mongo \   # linked container with running mongo
    twnel/<my_image_name>

To run backup once without cron job, add no-cron parameter:

docker run --rm \
    -v /path/to/target/folder:/backup \ # where to put backups
    --link my-mongo-container:mongo \   # linked container with running mongo
    twnel/<my_image_name>
