Docker network error

ERROR: failed to create endpoint lamp_1 on network bridge: Error starting userland proxy: listen tcp 0.0.0.0:80: bind: address already in use.

It says, “address already in use”. This means that something on your system — probably a web server like Apache — is already listening on port 80. You will either need to (a) stop the web server, (b) select a different host port in the -p argument to docker run.
