docker run hello-world
Unable to find image 'hello-world:latest' locally docker: Error response from daemon: Get https://registry-1.docker.io/v2/: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers).
See ‘docker run --help’.
I found nothing to help when I did run the “help” command. What should I do now?
(I got similar no-go from “docker run -d -p 80:80 --name webserver nginx”.)
