Having created a Kubernetes cluster using Container Engine for Kubernetes, you'll typically want to try it out by deploying an application on the nodes in the cluster. For convenience, the Cluster page includes a Getting Started tab that makes it easy to view and copy the commands to:
- download the kubeconfig configuration file for the cluster
- download and deploy a sample Nginx application using the Kubernetes command line tool kubectl from the instructions in a manifest file
- start the Kubernetes Dashboard to view the deployed application running on nodes in the cluster
To deploy the sample nginx application:
If you haven't already done so, follow the steps to download the cluster's kubeconfig configuration file and set the KUBECONFIG environment variable to point to the file. See Downloading a kubeconfig File to Enable Cluster Access.
In a terminal window, deploy the sample Nginx application by entering
kubectl create -f https://k8s.io/docs/tasks/run-application/deployment.yaml
If the command fails to connect to
https://k8s.io/docs/tasks/run-application/deployment.yaml, go to the url in a browser and download the manifest file
deployment.yamlto a local directory. Repeat the
kubectl createcommand and specify the local location of the
Use the Kubernetes Dashboard or kubectl to confirm that the sample application has deployed successfully. For example:
kubectl proxyto start the Kubernetes Dashboard.
- Open a browser and go to
http://localhost:8001/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy/to display the Kubernetes Dashboard.
- Click Overview to see the applications deployed on the cluster.
You can see the Nginx sample application has been deployed as two pods, on two nodes in the cluster.
