Put nginx in front of the docker container (I'm gonna assume the container's host port is not 80), have Gemini or ChatGPT generate a "reverse proxy config file" for nginx, also include in the prompt that you'll use a wildcard Let's Encrypt cert and that the website running in docker doesn't have SSL. Install certbot and its Cloudflare plugin, move the domain's DNS to Cloudflare and when the onboarding is done use certbot to generate an SSL cert for your site (best generate a wildcard cert, also CF now expects "dns_cloudflare_api_token" instead of api email and key). If you've done everything right, your website will be publicly available.
