[QUESTION] Docker Compose

[cryptedx]

Hi there,

how can I run cup with docker compose?

Thanks :-)

[sergi0g]

Hello @cryptedx ! Thanks for asking this question! Here's a very basic compose you can use:

services:
  cup:
    image: ghcr.io/sergi0g/cup:latest # you can use another tag if you like
    restart: unless-stopped
    command: serve
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
    ports:
      - "8000:8000"

If you want to use a different port, or use the cup.json file, please check the documentation and convert the docker options to docker compose. If you have any questions or need help with a specific setup, please ask here!

You missed the docker.sock part. Here is the docker compose that works for me.

services:
  cup:
    image: ghcr.io/sergi0g/cup
    container_name: cup
    command: -c /config/cup.json serve -p 8000
    volumes:
      - ./config/cup.json:/config/cup.json
      - /var/run/docker.sock:/var/run/docker.sock
    ports:
      - 8000:8000
    restart: unless-stopped

Oh sorry you're right! I made this on the go so I missed that part. I'll update my comment. Thanks!

Thank you very much for your help guys. Unfortunately it won't start up completely. I can't access the WebUI and log does output only:

No log line matching the '' filter

I am using Portainer with Stacks. Usually I get everything running what I want but cup is doing something differnt.

This is the yaml which I am using:

services:
  cup:
    image: ghcr.io/sergi0g/cup:latest
    restart: unless-stopped
    command: serve
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
    ports:
      - "9000:9000"

When I run it with the docker command from the docs it runs fine. Have you tested it by yourself if it it really also working for you with compose?

Thanks

Ah I think I see the problem. You're probably running portainer on port 9000 (it's the default, along with 9443). At the same time, you're trying to use Cup on that same port. In that case the container itself should fail to start and there will obviously be no logs. The second issue in this setup is that Cup uses port 8000 by default, so you would need to pass -p 9000 as an argument to serve.

[cryptedx]

Portainer is running on 9443 and 8000 that's why I want to use 9000. I can run it with this command
$ docker run -tv /var/run/docker.sock:/var/run/docker.sock -p 9000:9000 ghcr.io/sergi0g/cup serve -p 9000
and can access the WebUI but I am always trying to run everything with compose, that's why I asked here.

Well, I just added -p 9000 to the config and tried it again. I could access the WebUI. Yesterday I did the same thing and it was not working! I swear :-D

I deleted the stack (compose) and recreated it with the same config. I can't access the WebUI again. SHOCK :-D

Ok what should I do now? I started over without -p 9000

services:
  cup:
    image: ghcr.io/sergi0g/cup:latest
    restart: unless-stopped
    command: serve
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
    ports:
      - "9000:9000"

and I am not able to reach the WebUI. Then again adding -p 9000 to the yaml:

services:
  cup:
    image: ghcr.io/sergi0g/cup:latest
    restart: unless-stopped
    command: serve -p 9000
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
    ports:
      - "9000:9000"

I can reach the WebUI and log shows:

This behavior is confusing my mind ;-) Any idea what that could be?

[sergi0g]

It's mentioned in the docs. If you want to run on port 9000 you need to pass -p 9000. It's just how you inform Cup that you want it to run on port 9000. It's mostly intended for users who don't run Cup with Docker. For Docker, you can avoid passing -p 9000 entirely by exposing the port as 9000:8000. Portainer should make that easy.

[sergi0g]

Also, you might be interested in Runtipi: https://github.com/runtipi/runtipi. Cup is available as an app there.

[cryptedx]

Ok thanks. I removed -p 9000 and changed it to 9000:8000. Now I can always recreate it without any issues.

Have a nice evening!

Great! I'm happy I could help!
