You can start from it and modify it as you need. Here's the [documentation related to `nginx-rtmp-module`](https://github.com/arut/nginx-rtmp-module/wiki/Directives).

## RTMPS (RTMP with TLS)

RTMP is an unencrypted protocol. If you would like to wrap the RTMP session in a TLS session, you can modify the Nginx configuration as show below. This allows the user to stream to rtmps://[domain]:1935.

Modified `nginx.conf` to utilize RTMPS:

```Nginx
worker_processes auto;
rtmp_auto_push on;
events{}

stream {
upstream backend {
server 127.0.0.1:1936;
}
server {
listen 1935 ssl;
proxy_pass backend;
proxy_protocol on;
ssl_certificate /etc/letsencrypt/live/[domain]/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/[domain]/privkey.pem;
}
}

rtmp {
server {
listen 1936 proxy_protocol;
chunk_size 4096;

application live {
live on;
record off;
}
}
}

```

## Technical details

* This image is built from the same base official images that most of the other official images, as Python, Node, Postgres, Nginx itself, etc. Specifically, [buildpack-deps](https://hub.docker.com/_/buildpack-deps/) which is in turn based on [debian](https://hub.docker.com/_/debian/). So, if you have any other image locally you probably have the base image layers already downloaded.
