Port Range for docker installation

We have installed docker.io package (1.13.1)on ubuntu 16.04 server.

We are getting the below error message while running “docker run hello-world”.

docker:Error response from daemon: Get https://registry-1.docker.io/v1/: net/http: request canceled while waiting for connection.

As we have got stringent firewall policy , it will be helpful if we can get the port range that the above url may use.


Normally, you’d only need to open ports 80 and 443 for HTTP and HTTPS traffic from the server where the engine is running.
