This is a fork of https://github.com/istepanov/docker-mongodump -- Docker image with mongodump running as a cron task. I added scripts to automatize installation for a backup docker container.
First you have to build docker image from the repository:
docker build -t istepanov/mongodump .
After that you can install backup job for your mongodb docker container as follows (basically provide container name as an argument to install-backup.sh script):
$ docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
ea3a814c3720 campus2020portal_web:latest "node app.js" 6 days ago Up 5 days 0.0.0.0:8080->8080/tcp campus2020portal_web_1
39cae58c3dc8 mongo:latest "/entrypoint.sh mong 4 weeks ago Up 5 days 27017/tcp campus2020portal_mongo_1
$ ./install-backup.sh campus2020portal_mongo_1
This will run a docker container with cron job installed inside, which will backup mongodb once a day at 1.00 A.M. and save the output to /var/backups/mongodb as a .tar.gz archive. When you run docker via remote access (i.e. access remote docker host), the data will be saved on remote machine!
For configuration options, please, take a look inside the scripts. Crontab schedule is available in crontab file and 0 1 * * * by default.
To run backup once you can use the following script:
$ ./run-backup.sh campus2020portal_mongo_1
