Description

Pulls an image associated with a service defined in a compose.yaml file, but does not start containers based on those images.

Examples

suppose you have this compose.yaml:

services:
  db:
    image: postgres
  web:
    build: .
    command: bundle exec rails s -p 3000 -b '0.0.0.0'
    volumes:
      - .:/myapp
    ports:
      - "3000:3000"
    depends_on:
      - db

If you run docker compose pull ServiceName in the same directory as the compose.yaml file that defines the service, Docker pulls the associated image. For example, to call the postgres image configured as the db service in our example, you would run docker compose pull db.
