In this demonstration guide we provide multiple "Demo Snippets".
Demo Snippets are short demonstrations that can run independently from each
other.
When demonstrating any technology, its important to put the demonstrations into context, we gathered snippets into Tracks as a suggestion but you can mix and match snippets according to your audience.
You can create any demo with this fully functional environment, please feel free to email me your snippet [sborenst@redhat.com]
-
Goal - Demonstrate OpenShift Enterprise’s ability to simplify and streamline rapid application development.
-
Audience - This is a technical demonstration intended for technical resources, but you can present it at different depths.
-
Consider your audience’s areas of interest and select the most appropriate demo snippets:
-
Snippet - Deploy Application from a Docker Image and scale. (command line)
-

Note
|
It is assumed that you have OPENTLC credentials to access the RHPDS environment, and that have completed the OpenShift FASTRAX training. |
Follow the instructions in the Demonstration Environment Setup Page to provision and configure your environment.
When you provision your environment you will receive an email from OPENTLC with the connection details of your environment (IPs and hostnames not passwords).
Our environment is designed to demonstrate a highly scalable PaaS architecture. We created a 2 layer topology based on Regions and Zones.
Our master00 host will be used to host some of the management components of OpenShift Enterprise, Components such as the Web Console, The API service and the etcd store.
Infranode is a regular node like the others but by changing the labels applied to the node we are going to dedicate it to be used only for "Infrastructure containers". This is a design choice and not a mandatory constraint.
the nodes, nodes are hosts that are used to run containers (Pods) in the OSE environment, we label the two nodes to be in the same region but different zones. This is to simulate a use-case of an environment in a single region and possibly two cloud availability zones.
To get started, you need to:
-
Deploy your environment by following the instructions in the Demonstration Environment Setup page.
-
Allow about 30 minutes for provisioning and auto installation and about 5 minutes for running the demo deployment script.
-
-
Read the Legend and demonstration tips in the additional information page.
