Provide image for arm architecture (like Raspberry Pi)

[garret]

Would it be possible to provide also an official image for devices like the Raspberry Pi? ejabberd is so great that it can easily run on such low-powered devices and makes so much sense when you want to self-host a local private session.

I think this might also be easily achieved by the new docker buildx function that automatically creates images for other architectures, such as arm.

Yes, you can build multiple architectures in one single command with Docker Buildx. I wrote a quick tutorial here:

@ballerburg9005 your reply was addressed to me or to the developers of ejabberd?

[ballerburg9005]

@garret The developers.

I hope the Ejabberd devs will switch to Buildx soon as suggested.

Until then I made a slightly modified build myself:

https://hub.docker.com/r/ballerburg9005/docker-ejabberd-ecs-official-arm https://github.com/ballerburg9005/docker-ejabberd

I tested everything and I wrote everything down on Dockerhub that is not already part of the official tutorials and manuals. DynDNS, STUN/TURN Video calls and everything all working.

Check out the Dockerfile of my fork. It contains a docker hack with netstat to install contrib modules from ejabberdctl without docker failing. It works 99% of the time.

Any news on this? I, too, would like to use the official images on linux/arm64/v8 but only linux/amd64 seem to be available.

//edit: I just tried building it myself and it seems the issue is rooted even deeper:

//edit 2: Building the mix subfolder using docker build -t ejabberd/mix . first fixed the issue with building ecs.

Check out my modified build, it explains what you have to do.

BTW, since ejabberd 22.05, a new alternative container image is available in https://github.com/processone/ejabberd/pkgs/container/ejabberd and it's built for x64 and arm64.
