docker-compose pull预计阅读时间: 1 分钟
Usage: pull [options] [SERVICE...] Options: --ignore-pull-failures Pull what it can and ignores images with pull failures. --parallel Pull multiple images in parallel.
Pulls an image associated with a service defined in a
docker-stack.yml file, but does not start containers based on those images.
For example, suppose you have this
docker-compose.yml file from the Quickstart: Compose and Rails sample.
version: '2' 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
docker-compose.yml file that defines the service, Docker will pull the postgres image. For example, to call the
postgres image configured as the
db service in our example, you would run
docker-compose pull db.
