Improve installation note

[Antexa]

Hi @raph2i,

Could it be possible to get some instructions about to get it live ?

I would like to perform a standard installation for test like :

Client_iPhone -> LibreSpot -> SnapcastServer -> SnapcastClient.

Actually when I launch Snapcast server I get the following logs

I stumbled around the same problem on a raspberry pi 4. It seem to be a fault in the docker base os (alpine) regarding to https://gitlab.alpinelinux.org/alpine/aports/-/issues/11808.
I am not that familiar with this but here are some commands that helped me to resolve the issue on my system. Just SSH into your RPI and execute the following commands (copy & past all or execute line for line):

sudo su
docker run -it -d 7d3aa1ca/armv7-addon-snapcastserver bin/bash
sleep 10
DOCKER_PS_ID=$(docker ps | grep snapcastserver | awk '{print $1}')
docker exec -t $DOCKER_PS_ID apk update
docker exec -t $DOCKER_PS_ID apk upgrade
docker commit --change='CMD ["/init","/run.sh"]' $DOCKER_PS_ID 7d3aa1ca/armv7-addon-snapcastserver
docker kill $DOCKER_PS_ID

What it does:
#go root
#run docker image with bash instead of run.sh
#wait till docker image started
#save docker process id to variable
#update docker minimal os (apline)
#update docker minimal os (alpine)
#commit docker img changes with new execution commands
#kill used docker process

Hope that helps someone.

Hey @Antexa,
which hardware are you using? Maybe its a rpi4 problem like @FKainka

[JohnCashman]

Hey @raph2i ,

I am having the same issue as @Antexa. I am running Hassio on a RPI3.

Not sure how to use @FKainka solution. When I ssh to my Hassio, I can't find the docker command?

Any help would be great.
