docker compose pull

内容説明	Pull service images
利用方法	`docker compose pull [OPTIONS] [SERVICE...]`

内容説明

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

オプション

オプション	デフォルト	内容説明
`--ignore-buildable`		Ignore images that can be built
`--ignore-pull-failures`		Pull what it can and ignores images with pull failures
`--include-deps`		Also pull services declared as dependencies
`--policy`		Apply pull policy ("missing"\|"always")
`-q, --quiet`		Pull without printing progress information

利用例

Consider the following 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.

docker compose pull tries to pull image for services with a build section. If pull fails, it lets you know this service image must be built. You can skip this by setting --ignore-buildable flag.
