riot5576/200ok repository overview

⁠200ok

Tiny NGINX-based image that exposes five POST-only endpoints and returns 200 OK. Built on nginx:alpine-slim.

⁠What it does

  • Responds with 200 OK and body OK (text/html) only to POST requests.
  • Returns 405 Method Not Allowed (with Allow: POST) for any other method.
⁠Endpoints
Path
/Register2.aspx
/CheckRuntimePerpetual.aspx
/CheckRuntimeNetwork.aspx
/CheckLicense.aspx
/CheckRuntimeNetworkSecure.aspx

⁠Quick start

# Pull
docker pull riot5576/200ok:latest

# Run
docker run -d   --name 200ok-server   -p 80:80   --restart unless-stopped   riot5576/200ok:latest
⁠Verify
# Should return: OK
curl -X POST http://localhost/Register2.aspx

# Should return: 405 and Allow: POST
curl -i http://localhost/Register2.aspx

⁠Configuration

This image ships a single config at /etc/nginx/conf.d/default.conf with one location per endpoint, e.g.:

# /etc/nginx/conf.d/default.conf
server {
    listen 80;
    server_name _;          # catch-all host

    default_type text/html;

    ### Register2.aspx -----------------------------------------------
    location = /Register2.aspx {
        add_header Allow "POST" always;
        if ($request_method != POST) { return 405; }
        return 200 "OK";
    }

    ### CheckRuntimePerpetual.aspx -----------------------------------
    location = /CheckRuntimePerpetual.aspx {
        add_header Allow "POST" always;
        if ($request_method != POST) { return 405; }
        return 200 "OK";
    }

    ### CheckRuntimeNetwork.aspx -------------------------------------
    location = /CheckRuntimeNetwork.aspx {
        add_header Allow "POST" always;
        if ($request_method != POST) { return 405; }
        return 200 "OK";
    }

    ### CheckLicense.aspx --------------------------------------------
    location = /CheckLicense.aspx {
        add_header Allow "POST" always;
        if ($request_method != POST) { return 405; }
        return 200 "OK";
    }

    ### CheckRuntimeNetworkSecure.aspx -------------------------------
    location = /CheckRuntimeNetworkSecure.aspx {
        add_header Allow "POST" always;
        if ($request_method != POST) { return 405; }
        return 200 "OK";
    }
}

  • Default content type: text/html
  • Listens on port 80

⁠Build it yourself (optional)

FROM nginx:alpine-slim
COPY default.conf /etc/nginx/conf.d/default.conf
EXPOSE 80
docker build -t <your-tag> .
docker run -d --name 200ok-server -p 80:80 --restart unless-stopped <your-tag>

⁠Docker Compose (optional)

services:
  license:
    image: riot5576/200ok:latest
    container_name: 200ok-server
    ports:
      - "80:80"
    restart: unless-stopped

⁠Notes & tips

  • HTTPS is not needed for these endpoints, clients only use HTTP
  • Rate limiting or IP allowlists can be added with standard NGINX directives (limit_req, allow/deny) per location.
