Docker registry cleanup best practices

devopswizard · February 11, 2016, 11:44am

Hello Gents,

I am using docker and docker-registry for some time. Currently I am facing a disk space issue on a server, where docker-registry is running. My question is quite simple - are there some ‘best practices’ regarding maintaining docker-registry server? Especially I would like to know which of the images could be safely removed without harming developers work.
I appreciate for any tip or trick how to correctly manage docker registry.
Cheers!

delete the unused tags via the API, then run a clean up script.

We use this:

remove-orphan-images.sh

#!/bin/bash

JQPATH=$(which jq)
if [ "x$JQPATH" == "x" ]; then
  echo "Couldn't find jq executable." 1>&2
  exit 2
fi

set -eu
shopt -s nullglob
