docker-tasks

docker-tasks is a tool for executing periodic tasks via docker exec. It is looking up for running docker images and execute the specified commands in the matching container

An use case could be to dump all PostgreSQL based images to the container related volume. This allow me to backup /var/lib/docker/volumes/ with a pg_dump generated database dump inside my volumes.

Installation

pip install docker-tasks

Create a docker-tasks.yml with example commands

images:
    ubuntu:
      '*':
        - ps aux

    postgres:
      '9.*':
        - /bin/sh -c "pg_dump -U postgres postgres > /var/lib/postgresql/data/db_backup_$(date +%u).sql"

Usage

usage: docker-tasks [-h] [-c CONFIG] [-v]

optional arguments:
  -h, --help            show this help message and exit
  -c CONFIG, --config CONFIG
                        Config yaml. Default (docker-tasks.yml)
  -v, --verbose         Increase output verbosity
