AWS - Cannot create ElastiCache-CacheCluster - 'CacheSecurityGroup not found error'

Question

I have a cloud formation script shown below, I hope to create a Security Group and Elasti Cache. However I get an error shown below CREATE_FAILED AWS::ElastiCache::CacheCluster CacheSecurityGroup not found: elasticacheta....

I use cloudformation routinely but never with the cache. I do not want to use a VPC in my scenario and have gone through the documentation http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-elasticache-cache-cluster.html and related links but with no luck - help appreciated.

AWSTemplateFormatVersion: '2010-09-09'
Resources:
  ElasticacheSecurityGroup:
    Type: AWS::EC2::SecurityGroup
    Properties:
      GroupDescription: "Access from webservers only"
      SecurityGroupIngress:
      - IpProtocol: tcp
        CidrIp: 0.0.0.0/0
        FromPort: '11211'
        ToPort: '11211'
  ElasticacheCluster:
    Type: "AWS::ElastiCache::CacheCluster"
    DependsOn: ElasticacheSecurityGroup
    Properties:
      AutoMinorVersionUpgrade: "true"
      Engine: "memcached"
      CacheNodeType: "cache.t1.micro"
      NumCacheNodes: "1"
      CacheSecurityGroupNames:
      - Ref: ElasticacheSecurityGroup

Try using `AWS::ElastiCache::SecurityGroup` instead of `AWS::EC2::SecurityGroup` for non-VPC configurations. — jordanm, Nov 21 '16 at 07:27

Echoing jordanm's comment, change the resource type to AWS::ElastiCache::SecurityGroup

So it should look like this:

Resources:
  ElasticacheSecurityGroup:
    Type: AWS::ElastiCache::SecurityGroup
    Properties:
      Description: "Access from webservers only"
  ElasticacheCluster:
    Type: "AWS::ElastiCache::CacheCluster"
    DependsOn: ElasticacheSecurityGroup
    Properties:
      AutoMinorVersionUpgrade: "true"
      Engine: "memcached"
      CacheNodeType: "cache.t1.micro"
      NumCacheNodes: "1"
      CacheSecurityGroupNames:
      - Ref: ElasticacheSecurityGroup
