When trying to start a docker image I keep getting the error.
Error response from daemon: driver failed programming external connectivity on endpoint steamcache-dns (...) : Error starting userland proxy: listen udp 0.0.0.0:53: bind: address already in use
The ellipsis are a long random alphanumeric string that changes every time I try to start the image.
I am running it on a ubuntu in a virtual machine if that matters.
Any help on this would be greatly appreciated.
bind the port with a specific ip that way it doesn't have any conflicts.
Sounds like you have something already using port 53. Should be able to pinpoint what is causing this issue with:
netstat -upna | grep ':53 'I was able to pinpoint that it was dnsmasq that was using port 53. I was able to disabel dnsmasq by commenting out the dns=dnsmasq line in /etc/NetworkManager/NetworkManager.conf
Then ran these commands:
sudo service network-manager restart
sudo service networking restart
sudo killall dnsmasqThis disabled dnsmasq and then I was able to start the docker image successfully.
good to see you figured it out!
you can also use this to kill process on tcp/udp ports
fuser -k 53/tcp
where 53 is a port number.
