Command failed docker-compose in VScode Devcontainer

Question

I've just started using Docker on an already existing project (it runs into a Docker container). I don't have a lot of Docker background - I've been using it only from the GUI, by pressing the "play" button.

Now I have a project which runs into a container, and I'm having trouble starting it.

I'm getting this error:

Here's my docker-compose.yml (if it helps)

version: '3.7'

services:
  redis:
    //data

  postgres:
    //data

  django:
    //data

volumes:
  db-data:

Where can this error come from and how can I fix it?

Thanks.

It looks like you're trying to VS Code devcontainers. The error output is not super helpful here.

docker-compose seems to not like the format of your docker-compose.dev.yml file because it errors out on:

docker-compose -f c:\Users\Octavian\Desktop\django-analyzer\docker-compose.dev.yml config

Try running that command at your command line and it should give you better info on why your docker-compose.dev.yml is invalid.
