Docker and docker compose are installed

Help welcome, I'm a newbies with docker

Hi!

The only thing I was able to find about this problem is this issue: https://github.com/docker/compose/issues/8366

Are you sure docker-compose and docker are installed correctly? You may try to run some other image as a test, just to understand if the problem is with your setup or this image...

Hello,

I tried the classic hello world docker and it worked fine.

I've tried and succeeded to launch a docker and a docker-compose from scractch using this method ( https://docs.docker.com/compose/gettingstarted/#step-1-define-the-application-dependencies)

I therefore assume that the docker and docker-compose are correctly installed. But don't know what's wrong

Ok, I think now I understand better...

The compose module used to be a separate installation from docker and it was run with docker-compose (notice the dash). The new version of docker comes with the compose module already installed/integrated: you should try using docker compose (without dash). The command should work the same but I never tried. It should be still possible to install the docker-compose module manually (I didn't see it mentioned in the link you posted, I assume you don't have it), but I would try the other way first. If this doesn't work, please paste here the result of running "docker-compose --version" (once with and once without dash)

In between, I tested the following:

pip uninstall docker 
pip install docker==6.1.3

And now SandPi is running :-) I will try to go back to docker 7.0.0 and will keep you posted with the docker compose (without the dash)

Last update.

I made a fresh installation with the Raspberry Pi Image (v1.8.5), taken the raspebrry Pi OS (Legacy, 32 bit). Followed this guide to instal docker (https://docs.docker.com/engine/install/raspberry-pi-os/)

Run those 3 lines (no sure if they are completly necessary)

sudo groupadd docker
sudo usermod -aG docker ${USER}
su -s ${USER}

Run also this line to run fix permissions problem:

sudo chmod 666 /var/run/docker.sock

And finally run the following command (without the dash in docker-compose)

docker compose up -d

SandyPi is now running

Now I need to connect to my marlin board :-)

Perfect! Thank you for the update
