Raspberry Pi as Relay and Discovery Server


I am new here, just asking, is it possible to run the discovery Server and the relay server or one of them on a raspberry pi?

The docker discosrv was not possible to start, probably because it is amd64. Is it possible to build somehow my own docker containers that are compiled for arm32v7, go would probably also exist on rasbian, right?

Our Debian packages exist for arm, otherwise the individual GitHub releases for the discovery server and relay server should work.

Great, thank you for the fast reply, is it possible to put them in docker containers which I can update? Should be possible with the normal Dockerfile, right? Would be easier maybe to update through docker that way.

There are dockerfiles for them in the source repo, I guess running that on arm might generate arm dockerfiles?

No, sadly not, the get exec error (which means probably wrong architecture).

I tried the Dockerfile:
also with golang:1.13 or just golang nothing worked. Everytime I get the following error when I build the docker image:

Step 7/17 : RUN rm -f stdiscosrv && go run build.go -no-upgrade build stdiscosrv

I got both installed through normal debian apt install, docker would be still preffered, but it should work for now :slight_smile:
