Quickstart docker compose hangs on relational db about danswer

[chnadell]

I did a little more digging on this. Looks like there is a silent failure if there is already a postgres server on port 5432. Changing docker-compose.dev.yml to have:

  relational_db:
    image: postgres:15.2-alpine
    restart: always
    environment:
      - POSTGRES_USER=${POSTGRES_USER:-postgres}
      - POSTGRES_PASSWORD=${POSTGRES_PASSWORD:-password}
    ports:
      - "8002:5432"

solved the issue. I also had to do this for the nginx portion, since I already have an nginx service listening on 80. Surprisingly, the nginx container was noisy when the daemon errored:
Error response from daemon: driver failed programming external connectivity on endpoint danswer-stack-nginx-1 (9410c13fee582fdf3f7f214dc226b2a500ffc7091537320bc54c72e04f13e3b8): Error starting userland proxy: listen tcp4 0.0.0.0:80: bind: address already in use

while the relational db (postgres) container was not.

Ah yes, please make sure your ports are available. Ports 3000 for the web UI and 8080 for API server are also pretty standard ports to use.

Thanks for leaving your findings for future reference
