Docker error: invalid reference format: repository name must be lowercase

Question

Ran into this Docker error with one of my projects:

invalid reference format: repository name must be lowercase

What are the various causes for

Answer 1

This is happening because of the spaces in the current working directory that came from $(pwd) for map volumes. So, I used docker-compose instead.

The docker-compose.yml file.

version: '3'
services:
  react-app:
    build:
      context: .
      dockerfile: Dockerfile.dev
    ports:
      - "3000:3000"
    volumes:
      - /app/node_modules
      - .:/app
