## Examples

|
|
|
suppose you have this `compose.yaml`:
|
2021-03-11 16:20:30 +01:00
|
|
|
|
|
|
|
|
```yaml
|
|
|
|
|
services:
|
|
|
|
|
db:
|
|
|
|
|
image: postgres
|
|
|
|
|
web:
|
|
|
|
|
build: .
|
|
|
|
|
command: bundle exec rails s -p 3000 -b '0.0.0.0'
|
|
|
|
|
volumes:
|
2021-09-13 17:14:32 +02:00
|
|
|
- .:/myapp
|
2021-03-11 16:20:30 +01:00
|
|
|
ports:
|
2021-09-13 17:14:32 +02:00
|
|
|
- "3000:3000"
|
2021-03-11 16:20:30 +01:00
|
|
|
depends_on:
|
2021-09-13 17:14:32 +02:00
|
|
|
- db
|
2021-03-11 16:20:30 +01:00
|
|
|
```

|
|
|
If you run `docker compose pull ServiceName` in the same directory as the `compose.yaml` file that defines the service,
|
2021-03-11 16:20:30 +01:00
|
|
|
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`.
|
|
|
|
|
|

|
|
|
```console
|
2021-03-11 16:20:30 +01:00
|
|
|
$ docker compose pull db
