+
+The cluster URL is the address of your Kubernetes API server. The simplest way to find it is to use the `kubectl cluster-info` command:
+
+```bash
+kubectl cluster-info
+```
+
+This command works for all Kubernetes environments (managed services like GKE, EKS, AKS, or self-hosted clusters) and will show you the Kubernetes control plane address, which is your cluster URL.
+
+<Note>
+  Make sure the cluster URL is accessible from where you're running Infisical.
+  If you're using a private cluster, you'll need to configure a [Gateway](/documentation/platform/gateways/overview) to
+  access it.
