mmpm connection to MagicMirror failed

Kab

I did the cp ~/magicmirror/run/rpi_mmpm.yml ~/magicmirror/run/docker-compose.yml and reboot but got a black screen for the MagicMirror. So I replaced docker-compose.yml by the original file and rebooted again but the screen is still black.
I don’t know much about docker containers. I tried docker exec -it mm bash and it opened as usual.
What else is changed after reboot with the other container?

nothing

You can look into these yaml files, it`s all text.

You can see which containers are running with docker ps and may something is in the logs docker logs mm.

It takes some time pulling new images (this is done after a reboot).

Hi @karsten13

docker ps shows

CONTAINER ID   IMAGE                          COMMAND                  CREATED      STATUS          PORTS     NAMES
04fcaa798d2e   karsten13/magicmirror:latest   "/usr/bin/tini -- ./…"   3 days ago   Up 28 minutes             mm

and the first error in the log is

/home/node/.npm/_logs/2021-10-29T20_22_53_399Z-debug.log

the file is in the container, after executing docker exec -it mm bash you are in the container and then you should be able to see this file.

But the whole thing is strange.

You could reset the setup by

stop the container: navigate to ~/magicmirror/run and run docker-compose down
test there is no container running with docker ps
navigate to home directory executing cd
rename magicmirror folder with mv magicmirror magicmirror-old
reboot your pi

While starting the now missing magicmirror folder will be recreated from scratch.

Hi @karsten13

Thanks, that helped. I could go back to the previous setup.
mmpm still doesn’t work, though. I think I installed it wrong but need to dig deeper.
If I just ssh on the PI I can use mmpm but If I go into the mm container with docker exec -it mm bash it cannot find the mmpm command. Now I need to figure out how to remove my mpmm installation.
