The Problem

The pdk-docker image is currently an all-in-one that tries to serve many purposes, which is antithetical to what docker images are supposed to be.

With a growing number of conflicting requirements we believe the solution is to change the purpose of the PDK image to be a base image that can be built upon, allowing the community to create their own images built off this base.

Proposal

Instead of a single image, multiple tagged images will be published with each one catering to the specific puppet version you wish to run .e.g. puppet/pdk:puppet7

Each image will instead include:

• The version of Ruby shipped for the version of Puppet in this tag,
• the latest PDK gem,
• All dependent gems shipped for this version of Puppet in the PDK package

The immediate effect will be the removal of non PDK products from the base image. Popular products like onceover can either be explored as additional tags or separate images.
