Connection refused on nginx docker container

I've installed Docker Toolbox in macOS and I'm following Docker's simple tutorial on deploying Nginx.

I've executed docker run and confirmed that my container has been created:

docker run --name mynginx1 -P -d nginx
docker ps
40001fc50719  nginx  "nginx -g 'daemon off"  23 minutes ago  Up 23 minutes  0.0.0.0:32770->80/tcp, 0.0.0.0:32769->443/tcp  mynginx1

however when I curl http://localhost:32770, I get a connection refused error:

curl: (7) Failed to connect to localhost port 32770: Connection refused

I'm struggling to see what I could have missed here. Is there an extra step I need to perform, in light of me being on macOS?

In Mac for versions above 10, you can try using "docker.for.mac.host.internal" instead of "localhost"

EDIT: docker.for.mac.host.internal is deprecated, they switched to host.docker.internal. Reference: https://docs.docker.com/docker-for-mac/networking/#use-cases-and-workarounds

If you on OS X 10.10.3 Yosemite or newer and using Docker for Mac, you will not have docker-machine or docker toolbox or DOCKER_HOST to worry about.

Just map the port on run command local-port:container-port

docker run --name my-web  -p 8080:80

docker-machine ip default
xxx.docker.machine.ip

Then

curl http://xxx.docker.machine.ip:32770

The issue is that your DOCKER_HOST is not set to localhost, you will need to use the IP address of your docker-machine, since you are using Docker Toolbox:

docker-machine ip default # should return your IP address.

See Docker Toolbox Docs for more information.
