compose-backuper-script

Script to backup named volumes of your services from docker-compose.yml

It parses docker-compose.yml, finds named volume, runs a little container with these volumes mounted inside (ro) and saves it to backup file.

Little container is approximatenumber/compose-backuper.

Prepare

  1. Install needed python modules with virtualenv:
  1. virtualenv compose-backuper
  2. source compose-backuper/bin/activate
  3. pip install -r requirements.txt

(When you finish the backup, run deactivate to deactivate virtual environment)

  1. Pull the image for backup

docker pull approximatenumber/compose-backuper

Usage

Needed arguments:

  • docker-compose.yml (by default, script searches it in the current directory)
  • project name (by default, script takes current directory name)
  • destination directory to store backups.
  1. usage: compose-backup.py [-h] [-f COMPOSE_FILE] [-p PROJECT_NAME]
  2.                          [-d DESTINATION]
  4. optional arguments:
  5.   -h, --help            show this help message and exit
  6.   -f COMPOSE_FILE, --compose-file COMPOSE_FILE
  7.                         path to docker-compose.yml
  8.   -p PROJECT_NAME, --project-name PROJECT_NAME
  9.                         project name
  10.   -d DESTINATION, --destination DESTINATION
  11.                         destination directory for backups

Example:

  1. python compose-backup.py -f ../opt/app/docker-compose.yml -p myproj -d /opt/backups/
  3. INFO:compose-backup:jenkins-home: saving...
  4. INFO:compose-backup:jenkins-home: saved
  5. INFO:compose-backup:DONE! Volumes saved: 1
  1. ls /opt/backups
  3. myproj_jenkins-home.tar.gz
