AWS: Cloud Formation: Is it possible to use multiple "DependsOn"?

Question

Given i have this example template:

{     "AWSTemplateFormatVersion" : "2010-09-09",     "Mappings" : {         "RegionMap" : {             "us-west-1" : { "AMI" : "ami-655a0a20" },             ...         }     },     "Resources" : {         "Ec2Instance" : {             "Type" : "AWS::EC2::Instance",             "Properties" : {                 ...             },             "DependsOn" : "myDB"         },         "myDB" : {             "Type" : "AWS::RDS::DBInstance",             "Properties" : {                ...             }         },         "myDB2" : {             "Type" : "AWS::RDS::DBInstance",             "Properties" : {                ...             }         }     } } 

Is it possible to specify multiple DependsOn in any way? Would be great to have somethink like:

"DependsOn" : ["myDB", "myDB2"] 

Whats the normal way?

Answer 1

Yes,

The DependsOn attribute can take a single string or list of strings.

http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-attribute-dependson.html

Syntax:

"DependsOn" : [ String, ... ]

Answer 2

This answer comes up first in Google, so I will include how to do multiple dependson attributes in YAML, which I found in this answer.
