amazon web services - Cloudformation to automatically pick up the default instance profile -


i use cloudformation template deploy instance environment. want template pick default ec2 instance profile instance "arn:aws:iam::12345678910:role/ec2instanceprofile-instancerole-14f2a0atjnuo1"

i use same template every aws accounts have. however, problem instance profile name different in every account. randomly generated suffix attached name (in example 14f2a0atjnuo1). how can workaround problem make template reusable in every account. please provide code if possible.

    "ec2instanceprofile" : {       "description" : "the default instance profile",       "type": "string",       "constraintdescription" : "must name of existing defualt ec2 instance profile."     },  "iaminstanceprofile": { "ref": "ec2instanceprofile" }

get instance profile role name using below cloudformation.

"instanceprofile" : {   "type" : "aws::iam::instanceprofile",   "properties" : {     "path" : "/",     "roles" : ["your-role-name"]   } } "iaminstanceprofile": {"fn::getatt" : ["instanceprofile", "arn"] },

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
