Gradually turn on lights.

Thanks for the prompt responses guys. I might have to concede on this one and start my reactions again!

On another note. I have installed / configured docker-compose (or at least I thought I had). I don't seem to be able to use it to stop reactor:

pi@raspberrypi:~ $ docker stop reactor
Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Post "http://%2Fvar%2Frun%2Fdocker.sock/v1.24/containers/reactor/stop": dial unix /var/run/docker.sock: connect: permission denied
pi@raspberrypi:~ $ cd reactor
pi@raspberrypi:~/reactor $ docker stop reactor

If it's at a non-standard location, specify the URL with the DOCKER_HOST environment variable.

I should probably leave this to @toggledbits but what does

su docker stop reactor

do?

C

[Talisker]

pi@raspberrypi:~/reactor $ su docker stop reactor
su: user docker does not exist or the user entry does not contain all the required fields

[CatmanV2]

Oh sorry!

sudo docker stop reactor

DOH

C

[Talisker]

@catmanv2 I tried that thanks and it works:

sudo docker stop reactor #stops reactor
sudo service docker restart #starts reactor

Cheers!

@toggledbits thanks for the methodology. I manged to copy the files from a usb stick to the relevant folders using the sudo cp command. Feeling pretty pleased as I am now up an running on my raspberry pi.

[toggledbits]

Just add the pi user to the docker group on the Pi, and you won't have to sudo to use the docker or docker-compose commands.

# Run this command as user `pi`:
sudo usermod -a -G docker pi

Going forward, you should do everything related to the process (container) via docker-compose. You should rarely need or use the docker command itself.

@toggledbits something is not working quite right with my docker install (docker-compose). Not sure where to start!

[toggledbits]

Can you post your compose file? Also, I assume you ran the docker-compose command while in the same directory as the compose file? Did you start it with docker-compose? If not, you're probably going to get errors like this trying to stop it with docker-compose... the two commands are not interchangeable (for start/stop).

Sorry @toggledbits . I tied it again after a good break and it appears to work fine. I honestly don't know what was going wrong but things seem to now be in order:

pi@raspberrypi:~ $ cd reactor
pi@raspberrypi:~/reactor $ ls
config docker-compose.yml logs storage
pi@raspberrypi:~/reactor $ docker-compose down
Stopping reactor ... done
Removing reactor ... done
Removing network reactor_default
pi@raspberrypi:~/reactor $ docker-compose pull

docker-compose.yml below FYI:

Multi-System Reactor template docker-compose.yml (version 22160)
