Publish arm docker container as well as amd64

[cerebrate]

Should hopefully be simple enough; it builds just fine using the existing Dockerfile (to https://hub.docker.com/repository/docker/cerebrate/beehive , for example), but it would be good to have an official image that keeps pace with releases.

+1 to this request. I would be happy to contribute to getting this integrated in the release script as well.

A few observations,

• I could not find docker build or docker push inside either tools/release.sh or travis ci or the goreleaser files
• I assume, https://hub.docker.com/r/fribbledom/beehive, is now being pushed to manually by @muesli
• Maybe, we could try the following: https://medium.com/@quentin.mcgaw/cross-architecture-docker-builds-with-travis-ci-arm-s390x-etc-8f754e20aaef via travis with on.tags: true
• Although, to keep it simple, I think locally as well, the same could be done if who ever is doing the release can run the following. (this could also be added to release.sh)

docker buildx build \
     --progress plain \
    --platform=linux/amd64,linux/386,linux/arm64,linux/arm/v7,linux/arm/v6,linux/ppc64le,linux/s390x \
    -t $DOCKER_REPO:$TAG \
    --push \
    .

* I assume, https://hub.docker.com/r/fribbledom/beehive, is now being pushed to manually by @muesli

Correct, I'm currently running docker build and push manually after pushing a new release.

* Maybe, we could try the following: https://medium.com/@quentin.mcgaw/cross-architecture-docker-builds-with-travis-ci-arm-s390x-etc-8f754e20aaef via travis with `on.tags: true`

I'm currently trying to move away from TravisCI, which sadly has become just too unreliable. We could achieve something similar with GitHub Actions, of course, but I think ideally we integrate this with goreleaser. Contributions are more than welcome here! ❤️

Hey

I'm not familiar with Github Actions but I've attempted to add the docker buildx step to release.sh here: rhnvrm@84725cb

I was able to push to docker hub with multiple archs: https://hub.docker.com/r/rhnvrm/beehive/tags

For setting up buildx with multi arch you will need to do the following locally:

1. Add {"experimental":"enabled"} to /etc/docker/daemon.json and $HOME/.docker/config.json and restart docker sudo service docker start
2. Enable multi-arch builder

docker run --rm --privileged multiarch/qemu-user-static --reset -p yes
docker buildx create --name xbuilder --use

If you think this is enough, I can send a PR.

Found this recently,

https://github.com/crazy-max/ghaction-docker-buildx

Should we try adding this?

[muesli]

@rhnvrm Haven't tried docker-buildx before, but sounds intriguing. Isn't offering Docker Hub a similar integration, though? I'll have to read up on that.

[rhnvrm]

Hey, just read a bit more about this. Docker Hub also seems to provide it with pre/post hooks.

This repo shows how it can be done:

https://github.com/ckulka/docker-multi-arch-example
https://hub.docker.com/r/ckulka/multi-arch-example

It seems to rely on https://github.com/estesp/manifest-tool

Both methods have their merits.

One benefit, of setting up using buildx, might be that we can have a relatively easier way to build and push from local (if needed).

[muesli]

Another option would be using the already existing goreleaser setup (see .goreleaser.yml) to publish Docker builds. That would actually heavily improve and simplify the entire release process.

[rhnvrm]

I had explored this option as well but landed on goreleaser/goreleaser#530

[mhzawadi]

Hello,
Any news on this? would love to have a play, but only have pis at home

[rhnvrm]

It seems like the docker-buildx repo I had linked earlier has been moved under docker organization

https://github.com/docker/setup-buildx-action

I can give it a try with a new PR. What do you say @muesli ?

[muesli]

@rhnvrm Yeah, go ahead ❤️ Since goreleaser support is still WIP I'd say we should explore this route.

[rhnvrm]

@muesli I have updated #323

For testing, I created a dummy tag and pushed it in my fork: https://hub.docker.com/repository/docker/rhnvrm/beehive/tags?page=1

After merging, any tag pushed will be pushed to your dockerhub.

Two secrets will need to be set up:

DOCKERHUB_USERNAME
DOCKERHUB_TOKEN
