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?

If nginx is running in a container then your site is going to be 100% dead to the world while Docker isn't running. Users will get a connection error. When nginx is installed directly on your host you can serve a 503 maintenance page that doesn't depend on Docker or any containers running.
Nginx (pronounced "engine-x") is an open source reverse proxy server for HTTP, HTTPS, SMTP, POP3, and IMAP protocols, as well as a load balancer, HTTP cache, and a web server (origin server). The nginx project started with a strong focus on high concurrency, high performance and low memory usage.
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.
