This is a collection of highly-targetted demonstrations of Kubernetes features. The demos are all text-based and automated, making them perfect for customer meetings, meetups, or just showing off to your colleagues.
Running the demos
To run these demos you need
tmux installed, and you need
in your PATH.
Some of the demos try to act in faster-than-real time. For best results:
- SSH to your kubernetes-master and set the following flags (in this order):
- kube-controllermanager: --pod-eviction-timeout=10s
Before running a demo, make sure your cluster is demo-ready. The
script is provided for that.
Writing new demos
Each demo lives in its own directory. The bulk of the logic lives in
Demos should be small and focused - 2 to 3 minutes each.
Demos should be repeatable. Make sure you are not relying on timing effects.
If you need to
sleep, you might have a problem.
Demos should be self-contained. If you are depending on something being done before-hand, don't. Do it in the demo script.
Demos should be single-terminal. Use
tmux to split the window to show
multiple parallel things.
