docker: Error response from daemon: driver failed programming external connectivity on endpoint nginxx (2b5dc428167f20dfab55c573989562f9cc439ba0dfb94bae56085043dabf7613): Error starting userland proxy: listen udp4 0.0.0.0:443: bind: address already in use.

How to solve this problem?

Kill all processes using port 443.

CodePudding user response：

Please kill all process that use port 443:

for i in $(lsof -i -P -n  | grep 443 | awk '{print $2}'); do kill -9 $i ; done

then run your container again

sudo docker run -d -it -p 443:443 -p 443:443/udp --name nginxx nginxx

CodePudding user response：

I am using wireguard. Wireguard uses udp, and the port of wireguard is 443. When I stopped wireguard, docker execution succeeded.

I wonder why wireguard didn't show up when I used sudo netstat -nlutp | grep 443.
