Returns wrong result with base image debian:stable-slim for platform linux/386

[felfert]

Hi,

I am trying to use this action here, and it works with alpine as base-image, but always returns needs-updating=true when the base image is debian:stable-slim. I enabled action debugging and with my limited knowledge of docker manifest, it looks to me that the action picks the wrong architecture of the base image (amd64) metadata instead of the requested 386.

Debug log of the action run is here (was unable to attach it directly).

Thanks in advance

Hi @felfert

Sorry for the long wait. I checked and the action seems to be working fine for me for linux/386, I've added a test here #319

You can see that the action is getting the info for all the architectures, including linux/386 here

I think your image never gets updated here because you're missing --pull in the command.

I like to use https://github.com/docker/build-push-action which makes it easier to visualize all the parameters.
