Cloudflare Tunnels solve this elegantly. Here&rsquo;s how I wired it all up with <code>cloudflared</code>, HashiCorp Vault, ExternalSecrets, and FluxCD.</p> <figure><img src="https://uclab.dev/posts/cloudflare-tunnels/images/gemini9.png" alt="cloudflared-tunnel"> </figure> <h2 id="how-it-works">How It Works</h2> <p>Cloudflare Tunnels work by running a lightweight daemon (<code>cloudflared</code>) inside your cluster. This daemon opens an outbound connection to Cloudflare&rsquo;s edge — so no inbound ports need to be opened. Traffic hits <code>yourdomain.com</code>, Cloudflare routes it through the tunnel, and <code>cloudflared</code> forwards it to your internal service.</p>
