coTurn docker server setup for NextCloud Talk. I created this because I could not find any working and simple docker compose for the coTurn server. This compose is really simple to set up. It already has configured everything neccessary. Just change out your secret and realm and you're ready to go. Make sure to open the port 3488 and 49160-49200…
