Build PR Image Action

This Action provides automation for a Docker builder for a PR. An image is then pushed to a given registry.

Parameters

Inputs

• REGISTRY: The image registry where the action is pulling from. Images can be found in https://hub.docker.com/?namespace=vaporio
• BUILDERIMAGE: A base image containing the build tool chain
• SLIMIMAGE: A smaller image for deploys
• DOCKERFILE: Name of the Dockerfile. Usually just Dockerfile
• USERNAME: Login user for the image registry
• PASSWORD: Password for image registry

Usage

Since this Action is located in a private repo, a step will checkout this repo with a token so then it can be used in the next step.
