🚀 doup

A command line tool to find and update Docker-Image-Strings in project files.

Why you should using doup

The version of docker images should not set to latest to avoid upgrade nightmares. But containers should also be upgraded regulary to get new features and fixes of security issues.

So you have to check for each container individually if a new version is published on dockerhub. doup can save you a lot of time and is doing this task for you.

Example

Prepare your project for doup

Each Docker-Image-String has to be marked in the previous line:

# doup:latest
haproxy_docker_image: haproxy:2.6.2-bullseye

• doup: doup is looking for lines which contains doup:*
• latest: is the container tag on dockerhub which is used to get the newest version

QuickSetup

doup is published on PyPi and can be installed with pip install doup. Afterwards you should mark some Docker-Version-Strings in your project and run doup --dry-run.
