Backup your volumes from docker-compose.yml

docker devops

docker-compose is a great thing to deploy your services. It`s a new tool for, so maybe I am wrong, but I cannot find any usable solution to backup volumes from my services… Of course, I can do it manually, but it sucks :)

So, I made a small solution to make such things, compose-backuper-script . It is a python-script to backup named docker-compose volumes. It looks at docker-compose.yml, finds named volumes from services, runs small container with volumes (ro👌) and make a backup archive of data.

Read detailed manual how to use this script.

Simple example of usage:

$ python compose-backup.py -f ../opt/app/docker-compose.yml -p myproj -d /opt/backups/
INFO:compose-backup:jenkins-home: saving...
INFO:compose-backup:jenkins-home: saved
INFO:compose-backup:DONE! Volumes saved: 1

$ ls /opt/backups
myproj_jenkins-home.tar.gz

Thanks.
