The Javascript clients for Kubernetes is implemented in
[typescript](https://typescriptlang.org), but can be called from either
Javascript or Typescript.

For now, the client is implemented for server-side use with node
using the `request` library.

There are future plans to also build a jQuery compatible library but
for now, all of the examples and instructions assume the node client.

# Installation

```console
npm install @kubernetes/client-node
```

# Example code

## List all pods

```javascript
const k8s = require('@kubernetes/client-node');

const kc = new k8s.KubeConfig();
kc.loadFromDefault();

const k8sApi = kc.makeApiClient(k8s.Core_v1Api);

k8sApi.listNamespacedPod('default').then((res) => {
    console.log(res.body);
});
```

## Create a new namespace

```javascript
const k8s = require('@kubernetes/client-node');

const kc = new k8s.KubeConfig();
kc.loadFromDefault();

const k8sApi = kc.makeApiClient(k8s.Core_v1Api);

var namespace = {
    metadata: {
        name: 'test',
    },
};

k8sApi.createNamespace(namespace).then(
    (response) => {
        console.log('Created namespace');
        console.log(response);
        k8sApi.readNamespace(namespace.metadata.name).then((response) => {
            console.log(response);
            k8sApi.deleteNamespace(namespace.metadata.name, {} /* delete options */);
        });
    },
    (err) => {
        console.log('Error!: ' + err);
    },
);
```

## Create a cluster configuration programatically
```javascript
const k8s = require('@kubernetes/client-node');

const cluster = {
    name: 'my-server',
    server: 'http://server.com',
};

const user = {
    name: 'my-user',
    password: 'some-password',
};

const context = {
    name: 'my-context',
    user: user.name,
    cluster: cluster.name,
};

const kc = new k8s.KubeConfig();
kc.loadFromOptions({
    clusters: [cluster],
    users: [user],
    contexts: [context],
    currentContext: context.name,
});
const k8sApi = kc.makeApiClient(k8s.Core_v1Api);
...
```
