Title Instantly Run An App in the Cloud Using OpenShift Part 2
Overview A follow-on to traching students about creating apps in an online open source cloud environment - OpenShift. This time students focus on command-line driven tools, and the backends of building and deploying new application code via git.
Prerequisite Knowledge
Learning Objectives
  • Give instructor SSH access
  • Install and run "rhc" command-line client tool
  • Understand behind-the-scenes workflow of "git push"
  • Add custom build and deployment code
  • Synchronize Local and Live Environments (Test vs Prod)

Build phase.png



Background:

What is the rational for this activity? This second portion of the cloud app activity goes a little deeper and focuses on de-facto technologies like ssh / shell-access and git / github. Students will now take their new-found knowledge of the cloud paradigm and start to understand how it can link to a more technically flexible solution set. They can now customize their apps via editing and pushing code via a git publication process.

You will want to have already stepped through this preceding activity: Instantly_Run_An_App_in_the_Cloud


Directions:

Give Instructor SSH Access:

In order to fully inspect your work, the instructor will need access to your SSH shell that you created. You do not, however, want to give your same private key away. You could, but it is not the best industry practice. Instead, you will want to setup access for the instructors Username and his particular Public Key. Given a Public Key, the instructor can get in with their secret Private Key.

You are encouraged to look up instructions [the web].

OpenShift Tutorial 2

Priorly, we setup Wordpress blogging software and used it. Now we will dive into more usage of the command line, specifically the rhc command, and what occurs when new code is added via git push. Additionally we will learn how to run it all on your local laptop, so that you can test and develop in a safe environment before you push it live (into production).

Follow this tutorial:



Deliverables:

Create another blog post, with public URL, that shows:

  1. What you learned
    • Both specific to OpenShift and generally about Cloud Computing and PaaS
  2. What troubles or more info you came across
    • Troubleshooting you did, additional info you learned about, etc
  3. What other ways you might use a PaaS environment in the future
    • What other apps and coding platforms / languages could you use?
  • Install and run "rhc" command-line client tool
  • Understand behind-the-scenes workflow of "git push"
  • Add custom build and deployment code
  • Synchronize Local and Live Environments (Test vs Prod)

Assessment:

How will the activity be graded?

How will learning will be measured?

Include sample assessment questions/rubrics.

Criteria Level 1 (fail) Level 2 (pass) Level 3 (exceptional)
Give instructor SSH access
Install and run "rhc" command-line client tool
Understand behind-the-scenes workflow of "git push"
Add custom build and deployment code
Synchronize Local and Live Environments (Test vs Prod)
