How do I start one service in docker-compose without checking for or starting any dependencies?

Question

We are using docker-compose in our dev environment to start all the services.

Does any one know if I can start just 1 service using docker-compose without checking if dependencies are running or not (since I know they are running)?

$ docker-compose -f docker-compose-service1.yml  up

it gives an error: ERROR: Service ‘service1’ depends on service ‘service2’ which is undefined.

The yml file looks something like:

version: '2'
services:

  service1:
    build: ./service1
    dns: 192.168.1.100
    depends_on:
      - "service2"
    container_name: service1

I just want to start service1 since I know all the dependencies are already running.

If other services are running and you want to restart only one, you can use

docker-compose -f docker-compose.yml restart service1

Edit:

Regarding error:

ERROR: Service ‘service1’ depends on service ‘service2’ which is undefined.

It is because the docker-compose.yml which is used to up the services is not acceptable to docker-compose. First the yml file is compiled (the point of failure in our case) to see if everything is as per proper syntax, and then it is executed.
