Reports property as invalid when it is valid

[aap69]

When validating a cfn template with a resource of type AWS::EC2::SpotFleet, I get the following error:

cfn-lint error:

2018-10-30T06:42:04.6891330Z 1 crit 2018-10-30T06:42:04.6891404Z Resource: Resources > spotFleet > Properties > SpotFleetRequestConfigData > LaunchTemplateConfigs 2018-10-30T06:42:04.6891539Z Message: LaunchTemplateConfigs is not a valid property of AWS::EC2::SpotFleet.SpotFleetRequestConfigData 2018-10-30T06:42:04.6892453Z Documentation: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-ec2-spotfleet.html 2018-10-30T06:42:04.6892703Z 2018-10-30T06:42:04.6892914Z Template invalid!

template snippet for resource:

spotFleet: Type: AWS::EC2::SpotFleet DependsOn:

• spotFleetRole Properties: SpotFleetRequestConfigData: AllocationStrategy: "lowestPrice" IamFleetRole: Fn::GetAtt:
  • spotFleetRole
  • Arn ReplaceUnhealthyInstances: true TargetCapacity: Ref: TargetCapacity ValidFrom: !Ref FleetStart ValidUntil: !Ref FleetStop TerminateInstancesWithExpiration: true LaunchTemplateConfigs:
    • LaunchTemplateSpecification: LaunchTemplateName: Ref: LaunchTemplateName Version: Ref: LaunchTemplateVersion Overrides:
  • InstanceType: !Ref InstanceType SubnetId: !Select [ 0, !Ref SubnetIds ] WeightedCapacity: 1
  • InstanceType: !Ref InstanceType SubnetId: !Select [ 1, !Ref SubnetIds ] WeightedCapacity: 1
  • InstanceType: !Ref InstanceType SubnetId: !Select [ 2, !Ref SubnetIds ] WeightedCapacity: 1

AWS cfn documentation shows valid property LaunchTemplateConfigs: https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-ec2-spotfleet-launchtemplateconfig.html

The template launches successfully, as expected.

Hi @aap69, can you test this with the latest version of cfn-lint v1.9.1. The aws cloudformation specification has just been updated. Thanks!
