Docker image with membrane_webrtc_plugin

Hi! I have some issues with running a Phoenix app in a Debian-based docker. Whereas it can be built, when I am running it, it crashes:

I figured out some additional information. It has nothing to do with Docker. When I am running server with mix phx.server it works fine. It only crashes after it is built into a release (which is essentially what Docker does).

Did you find this page helpful?
