Google Kubernetes client

Node.js client library for Google's Kubernetes API (https://github.com/GoogleCloudPlatform/kubernetes) You can use this library to call a Kubernetes API hosted in a Kubernetes master node using Node.js.

Install:

npm install node-kubernetes-client

Current endpoint support includes:

• events
• endpoints
• namespaces
• pods
• minions
• services
• replicationControllers
• nodes
• proxyMinions
• proxyNodes
• proxyPods
• proxyServices
• watchPods

Interaction is accomplished via client.<endpoint>.<method>. (see examples below)

Usage

Create client

Authentication can be done via either token or login. If, however, the token expires, the login info will be used to acquire a new token.

var Client = require('node-kubernetes-client');

var client = new Client({
    host:  'xx.xx.xx.xx',
    protocol: 'https:',
    version: 'v1beta2',
    token: 'XYZ'
});

Optional params:

Some optional params also exist on initialising the client.

{
    namespace:  'someNamespace', // filter all client requests by a namespace - default is no namespace
    timeout: 20000 // A timeout (in ms) for requests to k8 apis
}

Getting from pods

Paging is accomplished automatically. For example, a request for pods will return all pods, not just those returned on the first page.

For example, to get all pods:

client.pods.get(function (err, pods) {
    console.log('pods:', pods);
});

Retrieving from Custom Collections

Retrieving from custom k8 collections is enabled by using the createCollection functionality.

For example, to create a custom collection called "routes":

var schema = null, //optional param
innerCollections = null, // optional param
options = { apiPrefix : 'api2' }; // optionally set a per-collection api prefix
client.routes = client.createCollection('routes', schema, innerCollections, options);
// then use the routes collection like any other

How to run the test cases

install mocha

  npm install mocha

run testcase

  mocha test-pods.js

The results will be output to test/results/ directory with formatted JSON.
