If you are receiving this:

as-create-auto-scaling-group:  Service error: Launch configuration name not found – null

Ensure you have set the region!! This was missing out of many of the docs I have read and appears that it only affects EU nodes.


For example;

as-create-auto-scaling-group xxscale –launch-configuration xxlaunch –region eu-west-1 -availability-zones eu-west-1a,eu-west-1b,eu-west-1c –min-size 1 –max-size 10  –load-balancers LoadBalancerX –health-check-type ELB –grace-period 300
