Root Cause

docker-compose references an env_file that doesn't exist.

generic

Workarounds

  1. 95% success Create the .env file from the example: cp .env.example .env 
    cp .env.example .env

    Sources: https://docs.docker.com/reference/compose-file/services/#env_file

  2. 88% success Make env_file optional with required: false (Compose V2) 
    env_file:
  - path: .env
    required: false

    Sources: https://docs.docker.com/reference/compose-file/services/#env_file

Dead Ends

Common approaches that don't work:

  1. Remove env_file from docker-compose.yml 60% fail

    May break the application that expects those env vars

  2. Create an empty .env file 55% fail

    App may fail with missing required env vars
