The Go client can use the same [kubeconfig file](/docs/concepts/configuration/organize-cluster-access-kubeconfig/)
as the kubectl CLI does to locate and authenticate to the API server. See this [example](https://git.k8s.io/client-go/examples/out-of-cluster-client-configuration/main.go):

```golang
package main

import (
  "context"
  "fmt"
  "k8s.io/apimachinery/pkg/apis/meta/v1"
  "k8s.io/client-go/kubernetes"
  "k8s.io/client-go/tools/clientcmd"
)

func main() {
  // uses the current context in kubeconfig
  // path-to-kubeconfig -- for example, /root/.kube/config
  config, _ := clientcmd.BuildConfigFromFlags("", "<path-to-kubeconfig>")
  // creates the clientset
  clientset, _ := kubernetes.NewForConfig(config)
  // access the API to list pods
  pods, _ := clientset.CoreV1().Pods("").List(context.TODO(), v1.ListOptions{})
  fmt.Printf("There are %d pods in the cluster\n", len(pods.Items))
}
```

If the application is deployed as a Pod in the cluster, see
[Accessing the API from within a Pod](/docs/tasks/access-application-cluster/access-cluster/#accessing-the-api-from-a-pod).

#### Python client

To use [Python client](https://github.com/kubernetes-client/python), run the following command:
`pip install kubernetes`. See [Python Client Library page](https://github.com/kubernetes-client/python)
for more installation options.

The Python client can use the same [kubeconfig file](/docs/concepts/configuration/organize-cluster-access-kubeconfig/)
as the kubectl CLI does to locate and authenticate to the API server. See this
[example](https://github.com/kubernetes-client/python/blob/master/examples/out_of_cluster_config.py):

```python
from kubernetes import client, config

config.load_kube_config()

v1=client.CoreV1Api()
print("Listing pods with their IPs:")
ret = v1.list_pod_for_all_namespaces(watch=False)
for i in ret.items:
    print("%s\t%s\t%s" % (i.status.pod_ip, i.metadata.namespace, i.metadata.name))
```

#### Java client

To install the [Java Client](https://github.com/kubernetes-client/java), run:

```shell
# Clone java library
git clone --recursive https://github.com/kubernetes-client/java

# Installing project artifacts, POM etc:
cd java
mvn install
```

See [https://github.com/kubernetes-client/java/releases](https://github.com/kubernetes-client/java/releases)
to see which versions are supported.

The Java client can use the same [kubeconfig file](/docs/concepts/configuration/organize-cluster-access-kubeconfig/)
as the kubectl CLI does to locate and authenticate to the API server. See this
[example](https://github.com/kubernetes-client/java/blob/master/examples/examples-release-15/src/main/java/io/kubernetes/client/examples/KubeConfigFileClientExample.java):

```java
package io.kubernetes.client.examples;

import io.kubernetes.client.ApiClient;
import io.kubernetes.client.ApiException;
import io.kubernetes.client.Configuration;
import io.kubernetes.client.apis.CoreV1Api;
import io.kubernetes.client.models.V1Pod;
import io.kubernetes.client.models.V1PodList;
import io.kubernetes.client.util.ClientBuilder;
import io.kubernetes.client.util.KubeConfig;
import java.io.FileReader;
import java.io.IOException;

/**
 * A simple example of how to use the Java API from an application outside a kubernetes cluster
 *
 * <p>Easiest way to run this: mvn exec:java
