docker-compose pullEstimated reading time: 1 minute
Usage: pull [options] [SERVICE...] Options: --ignore-pull-failures Pull what it can and ignores images with pull failures. --parallel Pull multiple images in parallel. --quiet Pull without printing progress information
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 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.
