Overview

This release addresses a few security fixes for dependent libraries and introduces some major enhancements.

!!! Please read carefully as there is new functoinality that is not directly backwards compatible !!!

ImageSwap v1.4.0 requires some new configuration settings and makes major changes to the default image swap logic.

Enhancements

• Introduces new MAPS swap mode logic (#29)
• Updates to logging when disable label is supplied (#29)
• Added a kustomize overlay for LEGACY swap mode (#29)
• Update image swap logic to preserve image org/project (#29)
• Update CI for Image Builds. Include multi-arch builds using buildx (#39)
• Bump KinD Version to 0.11.1 (#39)
• Bump KinD Node Images. Drop K8s v1.16 and add K8s v1.20 (#39)

MAPS LOGIC: There is a new MAPS mode logic that has been added to allow for more flexibility in the image swapping logic.
The existing logic, referred to as LEGACY mode, is still available, but has been deprecated.
To continue using the LEGACY mode logic set the IMAGESWAP_MODE environment variable accordingly. Please reference the configuration section for more information.

Image Definition Preservation: Updates have been made to how image definitions are processed during a swap. Previously the swap logic would drop the image org/project before adding the prefix (ie. nginx/nginx-ingress:latest would drop the nginx/ portion of the image definition).
In v1.4.0+ the swap logic will preserve all parts of the image except the Registry (ie. docker.io/nginx/nginx-ingress will drop the docker.io only from the image definition).
