When I run following commands, I can access 127.0.0.1:80 at localhost successfully.
docker run -p 127.0.0.1:80:80 --name Mynginx -dt nginx
docker exec -it Mynginx bash
But If I run the commands at digitalocean's DROPLETS, how to access it now? ( I tried to access DROPLETS's IP address:80, but I get nothing.)
