docker: driver failed programming external connectivity on endpoint webserver

If you are the port i not in use, try restarting docker. That usually works for me.

I had the same issue with one of my containers. I tried everything but when nothing worked, I tried the following and launched the container again with success

 sudo service docker stop
 sudo rm /var/lib/docker/network/files/local-kv.db
 sudo service docker start

Try restarting the docker service. It works 99% of the time.

service docker restart

If that didn't work as expected, try restarting your pc and then restarting the docker service using above command.

If none of the above worked try changing the exposed port to another unused port that should work.

docker run -d -p 81:80 --name webserver nginx

Note :- 81 is the port on your host and 80 is the port on your docker container

From your error message, the EADDRINUSE indicates port 80 is already in use on either the docker VM or possibly directly on your laptop. You can either stop whatever is running on that port, or change the port used in your Docker, command. To change to the external port 8080, use:

docker run -d -p 8080:80 --name webserver nginx
