What is the URL of my Docker service?

Question

My docker-compose.yml looks like this:

my_app:
  build: .
  net: host
  command: bin/server
  ports:
    - "3001:3001"

I start the service like this:

docker-compose up

And I can see that it is running:

my_app_1  | * Listening

But I can't figure out how to access it. None of these work:

localhost:3001
docker-machine:3001
127.0.0.1:3001
0.0.0.0:3001

How can I access my Docker service?

Answer 1

docker inspect container_name/hash | grep Address
