Chapter 3 ■ Kubernetes on Google Cloud Platform
Testing the Kubernetes Cluster
The cluster info may be listed with the following command:
kubectl cluster-info
As shown in Figure 3-59, the Kubernetes master and other cluster components are running.
Figure 3-59. Listing cluster info
Next, we shall create a Node application to test the cluster. Create a folder called hellonode (or some
other folder name). In the hellonode folder create a Node file server.js with the vi editor as shown in
Figure 3-60.
Figure 3-60. Creating a Node script server.js
The Node script server.js responds to any request with the response Hello World!.
var http = require('http');
var handleRequest = function (request, response) {
response.writeHead(200);
response.end('Hello World!');
};
var www = http.createServer(handleRequest);
www.listen(8080);
The server.js is shown in a vi editor in Figure 3-61.
