Description

Knowing how to administer and manage OpenShift from the command line using the oc tool is an essential skill that boosts productivity. Complementing this is OpenShifts S2I technology which focuses on streamlining the process of building repeatable and consistent containerized environments.

In this Lab scenario, you'll first use S2I to create a basic builder container image. The builder container image will then be used to build a runtime container image containing a simple static web portal application frontend. You'll then use the oc tool to launch and expose the containerized web portal application. 

Lab Objectives

Upon completion of this Lab, you will be able to:

  • Use the oc command and S2I technology to build a new container builder image
  • Use the oc command to inject web application source code into the new container builder image to produce a new runnable container image which is then launched
  • Use the oc command to expose the newly launched web application pod
  • Test and validate the container setup using the curl command and the browser

You should:

  • Be comfortable with basic Linux command line administration
  • Be comfortable with basic container concepts

Lab Environment

This Lab will start with the following AWS resources provisioned automatically for you:

  • Two EC2 instances:
    • ide.containers.cloudacademy.platform.instance - provides a web-based IDE which you will connect to using the assigned public IP address
    • openshift.cluster.cloudacademy.platform.instance - hosts an OpenShift 3.x Kubernetes cluster

To achieve the Lab end state, you will be walked through the process of:

  • Using your local workstation browser to remotely connect to ide.containers.cloudacademy.platform.instance
  • Using the web-based IDE and integrated terminal, you'll complete the remainder of the stated Lab Objectives (above)
