Unrecognized Resource Types

I'm trying to understand how Serverless works. I've gone through a lot of their docs / tutorials, however when I get to the part where I want to build something specific, like an RDS instance, I have no frame of reference for what the MVP will look like.

I found this Q/A post that showed what looked to be the basics for standing up an RDS instance. I swapped out the region for a more local one, then tried it out:

service: sandbox
app: sandbox
org: # omitting 

provider:
  name: aws
  runtime: nodejs12.x

resources:
  Resources:
    Vpc:
      Type: AWS:EC2::VPC
      Properties:
        CidrBlock: 10.0.0.0/16
        InstanceTenancy: default

    PublicSubnet:
      Type: AWS::EC2::Subnet
      Properties:
        CidrBlock: 10.0.0.0/18
        VpcId:
          Ref: Vpc

    PrivateSubnet1:
      Type: AWS::EC2::Subnet
      Properties:
        AvailabilityZone: ca-central-1a
        CidrBlock: 10.0.64.0/18
        VpcId:
          Ref: Vpc

    PrivateSubnet2:
      Type: AWS::EC2::Subnet
      Properties:
        AvailabilityZone: ca-central-1b
        CidrBlock: 10.0.128.0/18
        VpcId:
          Ref: Vpc

    Database:
      Type: AWS::RDS:DBInstance
      Properties:
        Engine: aurora
        EngineVersion: 5.6.10a
        DBInstanceClass: db.r5.large
        DBName: MyDatabase
        MasterUsername: test
        MasterUserPassword: # ommitting
        DBSubnetGroupName:
          Ref: DBSubnetGroup
        VPCSecurityGroups:
          - Ref: DatabaseVpcSecurityGroup

    DBSubnetGroup:
      Type: "AWS::RDS::DBSubnetGroup"
      Properties: 
        DBSubnetGroupName: PrivateDbSubnet
        DBSubnetGroupDescription: PrivateDbSubnet
        SubnetIds:
          - Ref: PrivateSubnet1
          - Ref: PrivateSubnet2

    DatabaseVpcSecurityGroup:
      Type: "AWS::EC2::SecurityGroup"
      Properties:
        GroupName: DBSecurityGroup
        GroupDescription: Allow local access
        SecurityGroupIngress:
          - CidrIp: 10.0.0.0/16
            IpProtocol: tcp
            FromPort: 3306
            ToPort: 3306
        VpcId: 
            Ref: Vpc

When I attempt to deploy this with Serverless, I get the following error: The CloudFormation template is invalid: Template format error: Unrecognized resource types: [AWS:EC2::VPC, AWS::RDS:DBInstance]

I can see that these resources exist on AWS:

So... what does this error mean? What Am I doing wrong?

Solution

  • You have typos in your resource type. In both cases you have a single colon (:) where you should have a double colon (::)
