Shows examples
Create load balancer group 'tfound-dev-web-lb' for web servers, in dev group for tfound:
python control-lb-and-groups.py --createlb --env dev --aws SC --type web
Add an instance to the load balancer group:
python control-lb-and-groups.py --addtolb=true --env dev --aws SC --type web --instance=i-999999
Create launch config using ami ami-fa6b8393 (default), medium sized instance, and Autoscale Group 'tfound-dev-web-group' with a min of 2 instances, max 5, with health check on port 80:
python control-lb-and-groups.py --createlc --ami ami-fa6b8393 --size c1.medium --env dev --aws SC --type web --createag --min 2 --max 5
Triggers/Health checks are hard coded to spawn new instances when total cpu reaches 60 percent or health check fails.
