docker-nginx-rtmp

A Dockerfile installing NGINX, nginx-rtmp-module and FFmpeg from source with default settings for HLS live streaming. Built on Alpine Linux.

• Nginx 1.14.1 (compiled from source)
• nginx-rtmp-module 1.2.1 (compiled from source)
• ffmpeg 4.1 (compiled from source)
• Default HLS settings (See: nginx.conf)

Usage

Server

• Pull docker image and run:

docker pull alfg/nginx-rtmp
docker run -it -p 1935:1935 -p 8080:80 --rm alfg/nginx-rtmp

or

• Build and run container from source:

docker build -t nginx-rtmp .
docker run -it -p 1935:1935 -p 8080:80 --rm nginx-rtmp

• Stream live content to:

rtmp://<server ip>:1935/stream/$STREAM_NAME

SSL

The nginx.conf is configured for both HTTP and HTTPS using a self-signed certificate supplied in /certs. If you wish to use HTTPS, it is highly recommended to obtain your own certificates and update the ssl_certificate and ssl_certificate_key paths in nginx.conf.

I recommend using Certbot from Let's Encrypt.

OBS Configuration

• Stream Type: Custom Streaming Server
• URL: rtmp://localhost:1935/stream
• Stream Key: hello

Watch Stream

• In Safari, VLC or any HLS player, open:

http://<server ip>:8080/live/$STREAM_NAME.m3u8

• Example: http://localhost:8080/live/hello
