+== Configuring a kubeconfig file by using the oc CLI
+
+You can use the `oc` Command-Line Interface (CLI) to log in to your OpenShift cluster and retrieve the `kubeconfig` file. The `kubeconfig` file contains the configuration information required to interact with the cluster using CLI tools such as `kubectl` or `oc`.

+= Accessing `kubeconfig` using the `oc` CLI
+
+You can use the `oc` CLI to log in to your OpenShift cluster and retrieve a kubeconfig file for accessing the cluster from the command line.
+
+.Prerequisites
+
+* You have access to the {product-title} web console or API server endpoint.
+
+.Procedure
+
+. Log in to your OpenShift cluster by running the following command:
++
+[source,terminal]
+----
+$ oc login <api-server-url> -u <username> -p <password> <1>
+----
++
+<1> Replace `<api-server-url>` with the full API server URL, such as `https://api.my-cluster.example.com:6443`.
+
+. Save the cluster configuration to a local file by running the following command:
++
+[source,terminal]
+----
+$ oc config view --raw > kubeconfig
+----
+
+. Set the `KUBECONFIG` environment variable to point to the exported file by running the following command:
++
+[source,terminal]
+----
+$ export KUBECONFIG=./kubeconfig
+----
+
+. You can now use `kubectl` to interact with your OpenShift cluster by running the following command:
++
+[source,terminal]
+----
+$ kubectl get nodes
+----
+
+[NOTE]
+====
+If you plan to reuse the exported `kubeconfig` file across sessions or machines, store it securely and avoid committing it to source control.
