Publish multi-arch image with docker buildx

[superbrothers]

With this PR, the grafana-image-renderer container image is published for arm64 in addition to amd64.

I've confirmed that the container image builds and publishes correctly with the following command:

I've confirmed that the published image works fine in amd64 and arm64 environments.

I've verified that this should work. Aside from possibly changing the docker version to the latest supported by CircleCI (20.10.17) - is there anything holding us back from deploying this for ARM64 in addition to AMD64?

[rickardp]

This needs to be rebased and use Drone instead of CircleCI as it looks like the build system was changed.

Any comments from the maintainers? I'm happy to help with the rebase if needed.

Yes, please! I'd be happy to review this once rebased and up-to-date with latest changes on master.

Thanks!

Would love to see this as well. Anything blocking it at this point?

I personally asked @superbrothers to pull latest changes from master, cause we're no longer using CircleCI.

However, as there has been no news since then, it's most likely we'll close this one in favor of https://github.com/grafana/grafana-image-renderer/pull/397, which I'm planning to review it & test it very soon.

[superbrothers]

Oh, sorry. I was not aware of that. I will do it this weekend.

[superbrothers]

I've just done it.

[mjgorman]

Alright, anything holding it up now? We're in the process of a Graviton migration and this is one of the few none arm64 images holding us up.
