Hey! I discovered Render today and love it so far. However, when I try to deploy the prebuilt Docker image coturn/coturn as a web service, I get this error that I’m unable to solve. The deploy logs say “operation not permitted” upon executing usr/bin/turnserver. You can see in their Docker file that setcap is used to allow rootless binding of privileged ports, but apparently that doesn’t work? I’ve tried various things with the command-line arguments, environment variables and a custom fork, but to no avail. Does anyone have an idea how to solve this?
