Fails on platforms with variants

[zinen]

I tried a lot of stuff that ended with an UNAUTHORIZED response from the docker API.

Some troubleshooting let me to that this error is gone if I remove the platforms with variants. E.g. removing linux/arm/v6 and linux/arm/v7 from the platforms input.

My code that fails:

jobs:
  get-docker-version:
    runs-on: ubuntu-latest
    steps:
      - name: Docker Image Update Checker
        id: check
        uses: lucacome/docker-image-update-checker@v1.2.1
        with:
          base-image: alpine:latest
          image: zinen2/alpine-pigpiod:latest
          platforms: linux/arm/v6,linux/arm/v7,linux/arm64
          # platforms: linux/arm64
        env:
          DEBUG: true

Hey @zinen, I run into a similar issue and created a fork to fix this issue. It's a bit tricky since the variant seams to be optional eg. linux/arm64 and linux/arm64/v8 means the same architecture. I have tested my new version with some of my repositories and it looks quite good. Would be great to know if my changes would also fix your issue - could you try it out by changing the action to clowa/docker-image-update-checker@342608bb9829d85eeeeb292e78115184b5a6657d ? Let me know if this fixes your issue too, then I will create a PR.

Tried this with clowa/docker-image-update-checker@342608bb9829d85eeeeb292e78115184b5a6657d and platforms: linux/arm/v6,linux/arm/v7,linux/arm64 and it did not throw an error. The logs from DEBUG: true indicated that your fork successfully loops the variants of my images and compares back to the base-image.

I think maybe you solved this.

Works with your fork (clowa/docker-image-update-checker@cebb3edee1fc9ed36c1526c23c784998c7ac2d75, the sha from previous comments isn't valid anymore), however..

Base Images from library seem to use linux/arm64/v8 as platform, when I build images on my own the v8 get's removed by Docker Build for whatever reason.

library/alpine 3:

dersimn/github-actions-to-docker-hub-simple, using this workflow:

This still fails with error Error: Platform linux/arm64/v8 not found in the image dersimn/github-actions-to-docker-hub-simple.
