About this Hands-on Lab

Helm provides solutions for customizing charts on the fly. In this hands-on lab, we will modify a chart to allow us to access our application on a node port in our cluster. Being able to access the chart values and knowing how to reference those values at install time can be invaluable in making sure the application works as expected in our environment.

Learning Objectives

Successfully complete this lab by achieving the following learning objectives:

Create a Release of the Ghost Blog Chart from the cloud_users Home Directory

Using Helm, get the configurable values from the ghost chart located in the cloud_users home directory. Release the chart into the default namespace in your Kubernetes cluster. Using the set directive, configure the service to type nodeport with a port number of 30080.

Verify the Blog Is Available at the Node Port on the Cluster

In a browser, navigate to the public IP address of the primary cluster server with the node port and ensure the ghost blog application loads.

Additional Resources

The development team is launching a new blogging platform, and they would like to stand up a test space so they can work on the configuration of the blogging platform. You will need to create a release of a ghost blog chart that is available on a node port in your cluster. Be sure to test the release to ensure that it is accessible on your cluster.
