This image runs y-websocket behind an Nginx reverse proxy and exposes it under the /ws/ path. Its purpose is to enable y-websocket servers to run on HTTP(S)-only services such as Amazon Lightsail.
The version of y-websocket used in this image accumulates documents in memory until it exhausts the available memory. To address this, the image includes a health checking service (accessible at /) that returns a status of 200 if memory usage is below 80%, and a status of 500 if it exceeds 80%. This allows Amazon Lightsail to restart the container before y-websocket becomes too sluggish.
You can use the following commands to build and run the image locally.
docker image build -t yjs-websocket-nginx .docker run -p 80:80 yjs-websocket-nginx:latest
You can then access the web socket via ws://localhost/ws.
