** (Code.LoadError) could not load /config/config.exs

When running the mix local.hex --force command via the docker file , we are getting these errors

** (Code.LoadError) could not load /config/config.exs
    (elixir) lib/code.ex:1147: Code.find_file/2
    (elixir) lib/code.ex:706: Code.eval_file/2
    (mix) lib/mix/config.ex:220: Mix.Config.eval!/2

    (mix) lib/mix/task.ex:331: Mix.Task.run_task/3
    (mix) lib/mix/cli.ex:78: Mix.CLI.run_task/2

We checked that the files are in proper location , can someone confirm that is this problem with our elixer config side or from the docker file ?

[c0b]

the /config/config.exs should be from your own project, are you sure it's properly mounted to the container?

Thanks @c0b That issue is fixed , now we are facing issue with linking postgres with the elixer app

version: '3'
services:
  web:
    build: 
      context: .
      dockerfile: Dockerfile
    expose:
      - "4000"
    ports:
      - "4000:4000"
    volumes:
      - .:/app
    depends_on:
      - db
  db:
    image: "postgres:9.6.3"

This is the compose file works good , but when we do mix phx.server the server is not getting started .

Giving DB connection error
