Automated Demo

This demo is intended to be used during KubeFed presentations.

Requirements

  • oc tool installed on your local machine
  • git and openssl commands available on your local machine
  • 3 existing OCP 4.1/3.11 clusters and a user with admin access

How-to

  1. Edit the inventory file inventory.json (you can use the template inventory.json.tmpl) or input the requested data interactively
  2. The script will run the scripted demo in an automated way

The inventory.json files requires the following information:

  • cluster1.url - Cluster1 domain name. e.g: east-1.example.com
  • cluster1.ocp_version - Cluster1 OCP Version. e.g: 3
  • cluster1.admin_user - Cluster 1 admin user. e.g: admin
  • cluster1.admin_password - Cluster 1 admin password. e.g: ver1secur3
  • cluster2.url - Cluster2 domain name. e.g: east-2.example.com
  • cluster2.ocp_version - Cluster2 OCP Version. e.g: 4
  • cluster2.admin_user - Cluster 2 admin user. e.g: kubeadmin
  • cluster2.admin_password - Cluster 2 admin password. e.g: ver1secur3
  • cluster3.url - Cluster3 domain name. e.g: west-2.example.com
  • cluster3.ocp_version - Cluster3 OCP Version. e.g: 4
  • cluster3.admin_user - Cluster 3 admin user. e.g: kubeadmin
  • cluster3.admin_password - Cluster 3 admin password. e.g: ver1secur3

auto-demo options

The script has three execution modes: demo (default), demo-cleanup and full-cleanup.

  • The demo mode will go through all the required steps to run the demo from beggining to end
  • The demo-cleanup mode will delete the demo resources while preserving the KubeFed and HAProxy bits
  • The full-cleanup mode will delete the demo resources and the federation bits (including the namespace where it was deployed)

On top of that the script allows the user to select which steps will be executed.

  • By default all steps will be executed.
  • User can select one or more steps from the list:
    1. context-creation - Logs into the clusters and create the required contexts on oc tool
    2. setup-kubefed - Setups Kubefed on the contexts created before
    3. setup-mongo-tls - Generates TLS certificates and modify some yaml resources accordingly
    4. demo-only - Runs the demo we all love

The script has a help command integrated which will tell you the supported execution modes and steps:

./auto-demo.sh -h
