This issue makes the latest "stable" release of Docker Desktop completely unusable for myself and my colleagues, who rely on the dnsmasq container with a port forward for UDP 53 for *.test domains. I want to run an application (the OLA server, olad) inside a container under Docker for Mac.(Version 18.06.1-ce-mac73 on Mojave, all up-to-date.) The particular OLA configuration I am using (for the Art-Net protocol) works by sending and receiving UDP broadcast data over port 6454 on a particular physical ethernet interface on the host, which is in turn connected to an external device under. => cd /var/folders/c8/l3c87j253jx43f5_whq5zsqc0000gn/T/dnstest.t8M3cNFLĬreating network "dnstestt8m3cnfl_default" with the default driverĬreating dnstestt8m3cnfl_dnsmasq_1. Avi Service Engine, Avi Controller, TCP 22 (SSH) TCP 8443 (HTTPS) UDP 123 (NTP) TCP 5098 (SSH) (if controller is a docker container, SSH is on port 5098). Running the same on the previous stable release of Docker for Mac (version 2.0.0.3) works as expected: connection timed out no servers could be reached => cd /var/folders/c8/l3c87j253jx43f5_whq5zsqc0000gn/T/dnstest.j1s2ZdZNĬreating network "dnstestj1s2zdzn_default" with the default driverĬreating dnstestj1s2zdzn_dnsmasq_1. Issue is fully reproducible and can be seen by running the script on this gist:.Also 20000-20050/udp for jigasi, in case you choose to deploy that to. Anything special I need to do for UDP ports on Mac I'd appreciate it any pointers or tips. In order to quickly run Jitsi Meet on a machine running Docker and Docker Compose. There are other users who reported similar issue there however with UDP port 53. I am logged into my Xbox Live account and can add the server but it never connects.
The issue appears to possibly be related to #3464, except for that task was originally opened as a result of TCP port 80. Actual behaviorĭocker Desktop for Mac v2.1.0.0 was released and as is normal, users on the stable release of Docker for Mac were prompted to upgrade:Īfter upgrading, my (and other team members) dnsmasq container ceased to function. So the question is: how do I create / run a docker container such that I am transmitting data, from inside the container, across a UDP port, for reading by a. I twitted about it, emailed several people and I still have no idea if. TCP and UDP port 53 (DNS) are bound on the host when Docker Desktop starts.
This is an artifact of the new amework in Big Sur. I have tried with the latest version of my channel (Stable or Edge)įorwarding 127.0.0.1:53:53/udp should work in the latest stable release of Docker Desktop. I found this bug which is pretty fundemental to having any use case for udp in docker. Disk flushes are particularly slow due to the need to guarantee data is written to stable storage on the host.
