It works by comparing the layers of your image (e.g. user/app:latest ) against the current layers of the base image you specify (e.g. debian:13.1 ), the image referenced in your Dockerfile's FROM instruction. If the base image was silently re-published under the same tag, for example because of a security patch or OS update, this action detects the drift so you can trigger a rebuild. [!NOTE] This is not the same as what Dependabot/Renovate does. Dependabot/Renovate opens PRs when a new tag is published (e.g. debian:13.1 → debian:13.2 ). This action handles the complementary case: the tag hasn't changed, but the image behind it has. By default this action checks differences across all platforms (e.g. linux/amd64,linux/arm64,linux/arm/v7 ), but you can specify which platforms to check.
