docker-check-base-image-diff

A Github Action that checks whether a derived image does not consist of a base image. Leverages skopeo and jq.

Based on lucacome's docker-image-update-checker.

Usage

Note that this action assumes that skopeo is installed; this appears to be true for GitHub's Ubuntu runners.

Inputs

base-image

A required argument, this represents the "base" image you want to check against.

As this is based on skopeo, it expects a string representing a container, and following a certain format (e.g. docker://rust:slim-buster). For more information, see the skopeo README.

Outputs

A required argument, this represents the "derived" image you want to check.

As this is based on skopeo, it expects a string representing a container, and following a certain format (e.g. docker://rust:slim-buster). For more information, see the skopeo README.
