# Rancher/Kubernetes Demo Application

This is a Go demo application used for demonstrating Kubernetes and load balancing.

It will create a colored icon for each replica within a ReplicaSet and indicate which one
most recently served a response. Replicas which haven't been heard from will begin to fade
out, until after a configurable number of seconds they will disappear. This is useful for 
demonstrating scaling up/down or in the case of an application like [Rio](https://rio.io),
for showing scale-in of an upgraded application.

## Environment Variables

- `TITLE`: sets title in demo app
- `SHOW_VERSION`: show version of app in ui (`VERSION` env var)
- `REFRESH_INTERVAL`: interval in milliseconds for page to refresh (default: 1000)
- `EXPIRE_INTERVAL`: how long a replica can go without being seen before we remove it from the display (default: 10s)
- `REMOVE_INTERVAL`: how long after `EXPIRE_INTERVAL` until we remove the icon (default: 20s)
- `SKIP_ERRORS`: set this to prevent errors from counting (useful on janky load balancers)
- `METADATA`: extra text at bottom of info area
- `COW_COLOR`: what color the cow background should be (default: black). Valid options are any color from the CSS pallete, including:
  - red
  - orange
  - yellow
  - olive
  - green
  - teal
  - blue
  - violet
  - purple
  - pink
  - black
