How to cache docker image

[halvardssm]

Hi! I find your action really useful, but the build time lasts quite long since it downloads the image on each build. Is there a way to cache the image between builds?

Thanks!

downloaded images are cached (somewhat) but here the problem is that the image is built anew each run. One way to fix this is build and upload the image to some registry, like Docker Hub, then update the image field in the action.yml.
For reference: https://docs.github.com/en/actions/creating-actions/metadata-syntax-for-github-actions#example-using-public-docker-registry-container

also @krizzu, I believe you don't have to pass inputs explicitly via args, they get passed down to your code anyway

To speed up this action, one can use action caching. Another way would be to have this docker image uploaded in Docker Hub.

@nyaaao what args are you referring to?

@krizzu I was referring to these https://github.com/Krizzu/eslint-check-action/blob/master/action.yml#L23-L27
