Parametrizing base image version in Dockerfile of Docker container Github action-CodePudding

I am following "Creating a Docker container action" and everything works great for me except that I would like to parametrize FROM field in my Dockerfile (I need to run CI tests against different versions of dependency, packaged as Docker image).

Ideally, in my Dockerfile, I'd like to use ARG or something something similar to:

ARG version=latest


FROM alpine:${version}

...

... but it is unclear how to pass build args.

Is there a way to something like this?

CodePudding user response：

I have not found a good way to do this out of the box.

At the moment Docker container action won't even let you to specify Dockerfile using arguments (through runs.image in action.yml).

The solution for me was using this action.
