IGNW Kubernetes Workshop Supporting Material

This repository contains the code and documentation used by IGNW for Kubenetes training.

• Kube 101 Walkthrough

In our workshops, we utilize a simple 2 tier demo application. The "frontend" app is a simple flask app (see below) that interacts with a redis key-value store. More advanced workshops utilize a microservices demo application with multiple n-tier services.

• Demo Application

Interacting with the application:

• [service_ip]:[port]/[key]/[value] will set a value

• [service_ip]:[port]/[key] will retrieve the key

• [service_ip]:[port] returns "Hello from k8s: "

• [service_ip]:[port]/healthz returns a HTTP 200 with "alive"

• [service_ip]:[port]/nhealthz returns a HTTP 500

• [service_ip]:[port]/load will cause the app to generate high CPU load for 5 seconds

Optional Configuration

• When the environment variable CHAOS is set to true then the app will terminate after a random number of requests between 1 and 100.
