Use Docker tags to add version control about deno_docker

[Minigugus]

I don't really know how Docker works with Github Actions, but I think you're right, "tags" seems the way to go (allows multiple tags for the same image). Maybe something like this could help:

    - name: Publish Docker
      uses: elgohr/[email protected]
      with:
-        name: "hayd/${{ matrix.kind }}-deno:${{ steps.get_version.outputs.VERSION }}"
+        name: "hayd/${{ matrix.kind }}-deno"
        username: ${{ secrets.DOCKER_USERNAME }}
        password: ${{ secrets.DOCKER_PASSWORD }}
        dockerfile: ${{ matrix.kind }}.dockerfile
        cache: true
-       tag_names: true
+       tags: "latest,${{ steps.get_version.outputs.VERSION }}"
    - name: Publish Docker Legacy
      if: matrix.kind != 'amazonlinux1'
      uses: elgohr/[email protected]
      with:
-        name: "hayd/deno:${{ matrix.kind }}-${{ steps.get_version.outputs.VERSION }}"
+        name: "hayd/deno"
        username: ${{ secrets.DOCKER_USERNAME }}
        password: ${{ secrets.DOCKER_PASSWORD }}
        dockerfile: ${{ matrix.kind }}.dockerfile
        cache: true
-       tag_names: true
+       tags: "latest,${{ matrix.kind }},${{ matrix.kind }}-${{ steps.get_version.outputs.VERSION }}"

However, I don't know how to tag the right latest image.

latest isn't defined? Hmm. I was hoping that supporting hayd/alpine-deno would have that "just work" (in hayd/deno latest could be any image...

I guess I am doing something wrong here:
https://github.com/hayd/deno-docker/blob/5be5b66f3b4eb365728d9c46671d79e6e80a190e/.github/workflows/publish.yml#L17-L35

Do you think any of options will fix?

Will play with this tonight and push a latest. 🤞 your diff suggestion "just works".
Thanks!

Nearly working: https://github.com/hayd/deno-docker/blob/cae47347e325bea12e317129afde8695e0750469/.github/workflows/publish.yml

I had wanted hayd/deno "latest" to be alpine, but for some reason it's used ubuntu so might need to experiment with this some more.

[Minigugus]

Maybe the tag is overritten when images are tagged, so that only the last image remains latest :
https://github.com/hayd/deno-docker/blob/cae47347e325bea12e317129afde8695e0750469/.github/workflows/publish.yml#L10
Maybe move the alpine image at the end : ['amazonlinux1', 'centos', 'debian', 'ubuntu', 'alpine'] ?

[hayd]

I think it's parallel and luck of the draw which wins (or maybe Ubuntu is slightly slower to build)!

I could sleep for 60seconds on alpine before building 😆 (hacky...)

[hayd]

I'm confident I have a solution that will work: using alpine as a separate build step. It seems like Publish-Docker-Github-Action is unhappy with two steps to the same repo in the same block (it never pushed the 0.37.0 tag to dockerhub that should have been just from alpine).

Related, it's unclear if I should be doing any of these things:
dockerimages@364f74b

(this fork/rename is a little weird.)
