chore: create multiarch docker image

[abemedia]

Currently the docker images only work on amd64 architecture. This PR adds support for armv7, arm64 and 386.

The versions in the migrate functions are using strings now as the number was too large for 32-bit architectures.

Thanks for the PR and sorry for being slow to respond.

I’m new to buildx so I had to do some research. Have you tried this action here before? https://github.com/docker/build-push-action

I’d prefer using the official Docker actions if possible. Apparently we could even replace that azure docker login as well (which I honestly don’t know I use that...)

Hi @goenning, thanks for the response.
That action only came out shortly before I did this PR so I hadn't heard of it yet at the time.
Happy to amend this PR to use that though.

[goenning]

@abemedia thanks for the update. the reason why I went with a separate workflow_run was to publish an image for each pull requests as well, so I'd like to keep that.

• push to main getfider/fider:main and getfider/fider:SHA_{sha7}
• pull request: getfider/fider:PR_{number}

@goenning still not working as v8go doesn't support these architectures. Currently working on an upstream PR for that.
Is that a new dependency btw? Because I've been using the ARM version in production for months.

As for the PR images that's being done via crazy-max/ghaction-docker-meta which I stumbled across on the docker/build-push-action docs. The naming is slightly different that your current one though (pr-$N instead of PR_$N).

[goenning]

1. Yes, v8go is a recent addition.
2. That won’t work because the workflow doesn’t have access to secrets, which is why I used workflow_run as recommended here https://securitylab.github.com/research/github-actions-preventing-pwn-requests/

[abemedia]

OK, will change that back and update the PR once rogchap/v8go#98 is merged.

@abemedia
It looks like this PR is merged. Do you think this will resolve the v8go issue?
I also need fider for arm64.

[goenning]

I think we’ll need to wait for rogchap/v8go#223 as well

[abemedia]

I've been using this branch on ARM for months now. All worked fine.

Oh, thanks! I'll try to build an image from this branch. @abemedia 👍
