2.2.2. Accessing kubeconfig by 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 OpenShift Container Platform web console or API server endpoint.

Procedure

Log in to your OpenShift cluster by running the following command:
```
$ oc login <api-server-url> -u <username> -p <password> 
```

1
Specify the full API server URL. For example: https://api.my-cluster.example.com:6443.
2
Specify a valid username. For example: kubeadmin.
3
Provide the password for the specified user. For example, the kubeadmin password generated during cluster installation.
Save the cluster configuration to a local file by running the following command:
```
$ oc config view --raw > kubeconfig
```
Set the KUBECONFIG environment variable to point to the exported file by running the following command:
```
$ export KUBECONFIG=./kubeconfig
```
Use oc to interact with your OpenShift cluster by running the following command:
```
$ oc get nodes
```

注意

If you plan to reuse the exported kubeconfig file across sessions or machines, store it securely and avoid committing it to source control.
