This example shows how to set up Auto Scaling with Elastic Load Balancing.To set up a load-balanced auto scaling configuration:
If you don’t already have a launch configuration, create one: euscale-create-launch-config MyLaunchConfig --image-id emi-50783D25 --instance-type m1.medium --group mysecuritygroup Create a new auto scaling group associated with a load balancer: euscale-create-auto-scaling-group MyScalingGroup --launch-configuration MyLaunchConfig --load-balancers MyLoadBalancer --availability-zones AcmeAvailabilityZone --min-size 2 --max-size 4 Authorize the security group used by the load balancer for back-end port communication. For example:
$ eulb-describe-lbs --show-long
LOAD_BALANCER MyLoadBalancer MyLoadBalancer-408396244283.elb.acme.eucalyptus-systems.com
{interval=200,target=HTTP:80/,timeout=3,healthy-threshold=2,unhealthy-threshold=4} AcmeAvailabilityZone
{protocol=HTTP,lb-port=80,instance-protocol=HTTP,instance-port=80}
{owner-alias=944786667073,group-name=euca-internal-408396244283-MyLoadBalancer}

euca-authorize mysecuritygroup -u 944786667073 -o euca-internal-408396244283-MyLoadBalancer -p -1 Verify that your Auto Scaling group has been created with a load balancer:
$ euscale-describe-auto-scaling-groups
AUTO-SCALING-GROUP MyScalingGroup MyLaunchConfig AcmeAvailabilityZone MyLoadBalancer 2 4 2 Default
INSTANCE i-DFCD0CBC AcmeAvailabilityZone InService Healthy MyLaunchConfig
INSTANCE i-B3431043 AcmeAvailabilityZone InService Healthy MyLaunchConfig
