class="page-content-title">Health Check Probes </h1> <p>This tutorial guides you through the process of using the node readiness endpoint, which provides a reliable way to determine if Kong Gateway is ready to serve user requests.</p> <p>The readiness check endpoint returns a <code class="language-plaintext highlighter-rouge">200 OK</code> response when Kong Gateway is ready, or a <code class="language-plaintext highlighter-rouge">503 Service Temporarily Unavailable</code> response when it’s not. This is useful for load balancers and other tools that need to monitor the readiness of Kong Gateway instances. When Kong Gateway is not ready, the endpoint responds back with a <code class="language-plaintext highlighter-rouge">message</code> field with the reason for unreadiness. This can be helpful to debug situations where the user expects that the node should be ready but is not.</p> <blockquote class="note"> <p><strong>Note:</strong> The readiness endpoint does not return detailed information about the node status.</p> </blockquote> <h2 id="types-of-health-checks">Types of health checks</h2> <p>For each Kong Gateway node, there are two distinct health checks (also known as “probes”):</p> <ul> <li> <p><strong>Liveness</strong>: The <code class="language-plaintext highlighter-rouge">/status</code> endpoint responds with a <code class="language-plaintext highlighter-rouge">200 OK</code> status if Kong Gateway is running. The request will fail either with a <code class="language-plaintext highlighter-rouge">500 Internal Server Error</code> or no response if Kong Gateway is not running. You can send a GET request to check the liveness of your Kong Gateway instance:</p> <div class="language-sh highlighter-rouge"> <div class="highlight"><pre class="highlight"><code><span class="c"># Replace localhost:8100 with the appropriate host and port for</span> <span class="c"># your Status API server</span> curl <span class="nt">-i</span> http://localhost:8100/status </code></pre></div> </div> </li> <li> <p><strong>Readiness</strong>: The <code class="language-plaintext highlighter-rouge">/status/ready</code> endpoint responds with a <code class="language-plaintext highlighter-rouge">200 OK</code> status if Kong Gateway has successfully loaded a valid configuration and is ready to proxy traffic. The request will fail either with a <code class="language-plaintext highlighter-rouge">503 Service Temporarily Unavailable</code> or no response if Kong Gateway is not ready to proxy traffic yet. You can send a GET request to check the readiness of your Kong Gateway instance:</p> <div class="language-sh highlighter-rouge"> <div class="highlight"><pre class="highlight"><code><span class="c"># Replace localhost:8100 with the appropriate host and port for</span> <span class="c"># your Status API server</span> curl <span class="nt">-i</span> http://localhost:8100/status/ready </code></pre></div> </div> </li> </ul> <p>These two types of health checks for Kong Gateway are modeled on how <a href="https://kubernetes.io/docs/tasks/configure-pod-container/configure-liveness-readiness-startup-probes/" target="_blank" rel="noopener nofollow noreferrer ">Kubernetes defines</a> health check probes.</p> <p>We strongly recommend that a component (that is, a load balancer) perform the readiness health check before sending traffic. This ensures that a Kong Gateway node has not only successfully started up but has also finished loading up the configuration and is ready to receive proxy traffic.</p> <p>The liveness health check may return a 200 OK response before the readiness health check does. Even if Kong Gateway is running, it may still be loading the full configuration, which means it is live but not ready. If a component only monitors the liveness probe to decide when to send traffic to Kong Gateway, there will be a short period of time where requests will be met with a <code class="language-plaintext highlighter-rouge">404 Not Found</code> response before the Kong Gateway is ready to proxy traffic. We recommend using the readiness probe over the liveness probe, especially in production environments.</p> <h2 id="understanding-the-node-readiness-endpoint">Understanding the node readiness endpoint</h2> <p>Before diving into the steps, it’s important to understand the purpose of the node readiness endpoint and how it determines whether a Kong Gateway instance is ready or not. The endpoint acts differently depending on the node type.</p> <div class="navtabs "> <div class="navtab-titles" role="tablist"> <div data-slug="traditional-mode" data-navtab-id="navtab-3c867e49-df45-40d1-89ec-220c46055b77-0" class="navtab-title" role="tab" aria-controls="navtab-id-0" tabindex="0"> Traditional mode </div> <div data-slug="hybrid-mode-data-plane-role-or-db-less-mode" data-navtab-id="navtab-3c867e49-df45-40d1-89ec-220c46055b77-1" class="navtab-title" role="tab" aria-controls="navtab-id-1" tabindex="0"> Hybrid mode (data plane role) or DB-less mode </div> <div data-slug="hybrid-mode-control-plane-role" data-navtab-id="navtab-3c867e49-df45-40d1-89ec-220c46055b77-2" class="navtab-title" role="tab" aria-controls="navtab-id-2" tabindex="0"> Hybrid mode (control plane role) </div> </div> <div class="navtab-contents"> <div data-panel="traditional-mode" data-navtab-content="navtab-3c867e49-df45-40d1-89ec-220c46055b77-0" class="navtab-content" role="tabpanel" id="navtab-id-0" tabindex="0" aria-labelledby="navtab-id-0"> <p>In <a href="/gateway/3.9.x/production/deployment-topologies/traditional/">traditional mode</a>, the endpoint returns <code class="language-plaintext highlighter-rouge">200 OK</code> when all of the following conditions are met:</p> <ol> <li>Successful connection to the database</li> <li>All Kong Gateway workers are ready to route requests</li> <li>All routes and services have their plugins ready to process requests</li> </ol> </div> <div data-panel="hybrid-mode-data-plane-role-or-db-less-mode" data-navtab-content="navtab-3c867e49-df45-40d1-89ec-220c46055b77-1" class="navtab-content" role="tabpanel" id="navtab-id-1" tabindex="0" aria-labelledby="navtab-id-1"> <p>In <a href="/gateway/3.9.x/production/deployment-topologies/hybrid-mode/">hybrid mode</a> (<code class="language-plaintext highlighter-rouge">data_plane</code> role) or <a href="/gateway/3.9.x/production/deployment-topologies/db-less-and-declarative-config/">DB-less mode</a>, the endpoint returns <code class="language-plaintext highlighter-rouge">200 OK</code> when the following conditions are met:</p> <ol> <li>Kong Gateway has loaded a valid and non-empty config (<code class="language-plaintext highlighter-rouge">kong.yaml</code>)</li> <li>All Kong Gateway workers are ready to route requests</li> <li>All routes and services have their plugins ready to process requests</li> </ol> </div> <div data-panel="hybrid-mode-control-plane-role" data-navtab-content="navtab-3c867e49-df45-40d1-89ec-220c46055b77-2" class="navtab-content" role="tabpanel" id="navtab-id-2" tabindex="0" aria-labelledby="navtab-id-2"> <p>In <a href="/gateway/3.9.x/production/deployment-topologies/hybrid-mode/">hybrid mode</a> (<code class="language-plaintext highlighter-rouge">control_plane</code> role), this endpoint returns <code class="language-plaintext highlighter-rouge">200 OK</code> when the following condition is met:</p> <ol> <li>Successful connection to the database</li> </ol> </div> </div> </div> <h2 id="enabling-the-node-readiness-endpoint">Enabling the node readiness endpoint</h2> <p>To use the node readiness endpoint, make sure that you have enabled the Status API server (disabled by default) via the <a href="/gateway/latest/reference/configuration/#status_listen"><code class="language-plaintext highlighter-rouge">status_listen</code></a> configuration parameter.</p> <p>Example <code class="language-plaintext highlighter-rouge">kong.conf</code>:</p> <div class="language-conf highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="n">status_listen</span> = <span class="m">0</span>.<span class="m">0</span>.<span class="m">0</span>.<span class="m">0</span>:<span class="m">8100</span> </code></pre></div></div> <blockquote class="note"> <p><strong>Note:</strong> Readiness probes should be used on every node within the cluster, including standalone, control plane, and data plane nodes.
