docker-compose start "ERROR: No containers to start"

I am trying to use Docker Compose (with Docker Machine on Windows) to launch a group of Docker containers.

My docker-compose.yml:

version: '2'
services:
postgres:
build: ./postgres
environment:
- POSTGRES_PASSWORD=mysecretpassword
frontend:
build: ./frontend
ports:
- "4567:4567"
depends_on:
- postgres
backend:
build: ./backend
ports:
- "5000:5000"
depends_on:
- postgres

docker-compose build runs successfully. When I run docker-compose start I get the following output:

Starting postgres ... done
Starting frontend ... done
Starting backend ... done
ERROR: No containers to start

I did confirm that the docker containers are not running. How do I get my containers to start?

The issue here is that you haven't actually created the containers. You will have to create these containers before running them. You could use the docker-compose up instead, that will create the containers and then start them.

Or you could run docker-compose create to create the containers and then run the docker-compose start to start them.

The reason why you saw the error is that docker-compose start and docker-compose restart assume that the containers already exist.

If you want to build and start containers, use

docker-compose up

If you only want to build the containers, use

docker-compose up --no-start

Afterwards, docker-compose {start,restart,stop} should work as expected.

There used to be a docker-compose create command, but it is now deprecated in favor of docker-compose up --no-start.
