autoscaling - AWS Autoscale Load Balancing with Cloudformation -


i'm trying create ec2 instance, use autoscaling, attached load balancer.

unfortunately, i'm getting error

the availability zones of specified subnets , autoscalinggroup not match

however, current cloudformation script:

"apiautoscaling" : {   "type" : "aws::autoscaling::autoscalinggroup",   "properties" : {     "vpczoneidentifier" : [ "subnet-5ff05206", "subnet-b1109fc6", "subnet-948ce5f1" ],     "instanceid" : {       "ref" : "apiec2"     },     "maxsize" : 3,     "minsize" : 1,     "loadbalancernames" : [ "api" ]   } }, "apiloadbalancer" : {   "type" : "aws::elasticloadbalancing::loadbalancer",   "properties" : {     "loadbalancername" : "api",     "listeners" : [       {         "instanceport" : "80",         "instanceprotocol" : "http",         "loadbalancerport" : "80",         "protocol" : "http"       },       {         "instanceport" : "80",         "instanceprotocol" : "http",         "loadbalancerport" : "443",         "protocol" : "https",         "sslcertificateid" : "arn:aws:iam::xxx"       }     ],     "securitygroups" : [ "sg-a88444cc" ],     "subnets" : [ "subnet-5ff05206", "subnet-b1109fc6", "subnet-948ce5f1" ]   } }

as can see, subnet list same both autoscaling group , load balancer. i've misunderstood how supposed work, can't work out.

try specifying availabilityzones property auto scaling group. default use of them, if subnets use subnet of zones, error message.

(as pointed out in comments, "availabilityzones" : { "fn::getazs" : "" } should trick.)
