docker compose run
| Description | Run a one-off command on a service |
|---|---|
| Usage | docker compose run [OPTIONS] SERVICE [COMMAND] [ARGS...] |
Description
Runs a one-time command against a service.
The following command starts the web service and runs bash as its command:
$ docker compose run web bash
Commands you use with run start in new containers with configuration defined by that of the service, including volumes, links, and other details. However, there are two important differences:
First, the command passed by run overrides the command defined in the service configuration. For example, if the
web service configuration is started with bash, then docker compose run web python app.py overrides it with
python app.py.
The second difference is that the docker compose run command does not create any of the ports specified in the
service configuration. This prevents port collisions with already-open ports. If you do want the service’s ports
to be created and mapped to the host, specify the --service-ports
$ docker compose run --service-ports web python manage.py shell
Alternatively, manual port mapping can be specified with the --publish or -p options, just as when using docker run:
$ docker compose run --publish 8080:80 -p 2022:22 -p 127.0.0.1:2021:21 web python manage.py shell
If you start a service configured with links, the run command first checks to see if the linked service is running and starts the service if it is stopped. Once all the linked services are running, the run executes the command you passed it. For example, you could run:
$ docker compose run db psql -h db -U docker
This opens an interactive PostgreSQL shell for the linked db container.
If you do not want the run command to start linked containers, use the --no-deps flag:
$ docker compose run --no-deps web python manage.py shell
If you want to remove the container after running while overriding the container’s restart policy, use the --rm flag:
$ docker compose run --rm web python manage.py db upgrade
This runs a database upgrade script, and removes the container when finished running, even if a restart policy is specified in the service configuration.
