Problem with port binding

Open julian-ladjani opened this issue 1 year ago • 2 comments

Description

Hello, I use colima since yesterday, I have a dns container working perfectly with docker, since I use colima, Ihave this problem: docker: Error response from daemon: driver failed programming external connectivity on endpoint nice_bell (b688f5012ab945b7d85e4f85a1ead26960501561deb75c417db4333e27b85db7): failed to bind port 0.0.0.0:53/tcp: Error starting userland proxy: listen tcp4 0.0.0.0:53: bind: address already in use. (same with udp), When I use 54 port (for exemple), it work fine. Maybe it's a permissions problem or something like that?

It simply means something is already using port 53.

You can check the program using it by running the following command.

lsof -nP -iTCP:53 | grep LISTEN

I tested with netcat before in addition to lsof (by listening to port 53 directly). Since we did not find a solution, we installed a dnsmasq and it works perfectly but not with docker-compose with colima (works with docker desktop).

I tried with two macs, it gives the same result

I'm installing pihole and get stuck too. finally figured out the port 53 usage, you have to colima ssh into runtime inside to run lsof -nP -iTCP:53 | grep LISTEN

tcp   LISTEN 0      4096         127.0.0.54:53        0.0.0.0:*    users:(("systemd-resolve",pid=227,fd=17))
tcp   LISTEN 0      4096      127.0.0.53%lo:53        0.0.0.0:*    users:(("systemd-resolve",pid=227,fd=15))

it's explained in pihole. https://github.com/pi-hole/docker-pi-hole?tab=readme-ov-file#installing-on-ubuntu-or-fedora
