A Docker container with the Coturn TURN server.
- hub.docker.com (Docker image): zenosmosis/docker-coturn
- github.com (Repo): zenOSmosis/docker-coturn
Note, for those who would rather build this sort of thing from scratch, here's an article written by the author of the original package we forked from: https://devblogs.microsoft.com/cse/2018/01/29/orchestrating-turn-servers-cloud-deployment.
docker run \
-d \
-p 3478:3478 \

-p 65435-65535:65435-65535/udp \
--restart=always \
--name coturn \
zenosmosis/docker-coturndocker-compose upThis image supports some environment variables:
USERNAME: Username needed for turn. Defaults tousernamePASSWORD: Password needed for turn. Defaults ropasswordREALM: Realm needed for turn. Defaults torealmMIN_PORT: This defines the min-port for the range used by turn. Defaults to65435MAX_PORT: This defines the max-port for the range used by turn. Defaults to65535
An example:
# This makes sure, that the min- and max-port is the same for all environment variables
export MIN_PORT=50000
export MAX_PORT=50010
docker run \
-d \
-p 3478:3478 \
-p 3478:3478/udp \
-p ${MIN_PORT}-${MAX_PORT}:${MIN_PORT}-${MAX_PORT}/udp \
-e USERNAME=another_user \
-e PASSWORD=another_password \
-e REALM=another_realm \
-e MIN_PORT=${MIN_PORT} \
-e MAX_PORT=${MAX_PORT} \
--restart=always \
--name coturn \
zenosmosis/docker-coturnAn easier example (if Docker Compose is installed)
docker-compose up(see docker-compose.yml for configuration)
Store the cert under /opt/cert.pem and the key under /opt/pkey.pem and mount them as volumes:
docker run \
-d \
-p 3478:3478 \
-p 3478:3478/udp \
-p 65435-65535:65435-65535/udp \
--volume /opt/cert.pem:/etc/ssl/turn_server_cert.pem \
--volume /opt/pkey.pem:/etc/ssl/turn_server_pkey.pem \
--restart=always \
--name coturn \
