ARM64 docker image not supported

[pagocs]

🚀 Feature Request

Description

I would like to test the beacon chain and the validator node on RPI 4 in docker but I cannot find compatible ARM64 image.

Describe the solution you'd like

Will this be supported or someone could help me how I could be built myself?

There is no current plan to support ARM64 based docker images.

I haven't tested this idea, but here's a thought that might be a good starting point for you to experiment. On an ARM device, build a docker image with a Dockerfile that looks something like this

FROM arm64v8/ubuntu

RUN apt-get install -y libstdc++ libgcc1 pgp

RUN curl https://raw.githubusercontent.com/prysmaticlabs/prysm/master/prysm.sh

CMD ./prysm.sh beacon-chain

[pagocs]

Thank you @prestonvanloon for the information. I managed to create docker containers (beacon and validator) which are run perfectly for days now.

Config: RPi 4 4GB RAM.

If it is interesting I could share the dockerfile and basic instructions to setup and launch.

Hey @pagocs that would be great, could you suggest it as a pull request or issue in our documentation portal here https://docs.prylabs.network ? Thank you!

I think we could publish x86 and arm images to dockerhub. It seems rules_docker supports platform transition rules bazelbuild/rules_docker#1963, that might be helpful.

I know that dockerhub supports both platforms with the same tag. Still looking at google container registry to see if both platforms could be supported with the same tag.

Can this be reconsidered please? I'm building a new setup around docker images/containers and arm hw, and I just realized this didn't work either using the docker hub repo or gcr.io.

Fixed in #12428. We are planning to switch to these multi-arch images, starting in the next release.
