Docker run failed with Error response from daemon

问题

I simply run the following command:

docker run -d -p 80:80 --name webserver nginx

and after pulling all images returns this error:

docker: Error response from daemon: driver failed programming external connectivity on endpoint webserver (ac5719bc0e95ead1a4ec6b6ae437c4c0b8a9600ee69ecf72e73f8d2d12020f97): Error starting userland proxy: Bind for 0.0.0.0:80: unexpected error (Failure EADDRINUSE).

Here is my docker Version info:

Client:
Version:      1.12.0
API version:  1.24
Go version:   go1.6.3
Git commit:   8eab29e
Built:        Thu Jul 28 21:15:28 2016

Server:
Version:      1.12.0
API version:  1.24
Go version:   go1.6.3
Git commit:   8eab29e

OS/Arch:      linux/amd64

How to fix this?

回答1:

You didn't provide informations such as Docker version, system or docker processes running so I assume the most likely situation.

The output contains: Failure EADDRINUSE. It means that port 80 is used by something else. You can use lsof -i TCP:80 to check which process is listening on that port. If there is nothing running on the port, it might be some issue with Docker. For example the one with not releasing ports immediately.
