[Closed] Coturn TURN server Docker image
PROJECT IS CLOSED AND ARCHIVED. NO MAINTAINING WILL BE CONTINUED.
Consider to use officialDocker image instead (source repo).
The TURN Server is a VoIP media traffic NAT traversal server and gateway. It can be used as a general-purpose network traffic TURN server and gateway, too.
To run Coturn TURN server just start the container:
bash docker run -d -p 3478:3478 -p 49152-65535:49152-65535/udp instrumentisto/coturn
As per RFC 5766 Section 6.2, these are the ports that the TURN server will use to exchange media.
You can change them with
max-portCoturn configuration options:
bash docker run -d -p 3478:3478 -p 49160-49200:49160-49200/udp \ instrumentisto/coturn -n --log-file=stdout \ --external-ip='$(detect-external-ip)' \ --min-port=49160 --max-port=49200
Or just use the host network directly (recommended, as Docker performs badly with large port ranges):
bash docker run -d --network=host instrumentisto/coturn
By default, default Coturn configuration and CLI options provided in
CMDDockerfile instruction are used.
You may either specify your own configuration file instead.
docker run -d --network=host \ -v $(pwd)/my.conf:/etc/coturn/turnserver.conf \ instrumentisto/coturn
Or specify command line options directly.
docker run -d --network=host instrumentisto/coturn \ -n --log-file=stdout \ --min-port=49160 --max-port=49200 \ --lt-cred-mech --fingerprint \ --no-multicast-peers --no-cli \ --no-tlsv1 --no-tlsv1_1 \ --realm=my.realm.org \
Or even specify another configuration file.
docker run -d --network=host \ -v $(pwd)/my.conf:/my/coturn.conf \ instrumentisto/coturn -c /my/coturn.conf
detect-external-ipbinary may be used to automatically detect external IP of TURN server in runtime. It's okay to use it multiple times (the value will be evaluated only once).
bash docker run -d --network=host instrumentisto/coturn \ -n --log-file=stdout \ --external-ip='$(detect-external-ip)' \ --relay-ip='$(detect-external-ip)'
By default, Coturn Docker image persists its data in
You can speedup Coturn simply by using tmpfs for that:
bash docker run -d --network=host --mount type=tmpfs,destination=/var/lib/coturn \ instrumentisto/coturn
This image is based on the popular Alpine Linux project, available in the alpine official image. Alpine Linux is much smaller than most distribution base images (~5MB), and thus leads to much slimmer images in general.
This variant is highly recommended when final image size being as small as possible is desired. The main caveat to note is that it does use musl libc instead of glibc and friends, so certain software might run into issues depending on the depth of their libc requirements. However, most software doesn't have an issue with this, so this variant is usually a very safe choice. See this Hacker News comment thread for more discussion of the issues that might arise and some pro/con comparisons of using Alpine-based images.
