aws cloudformation template for spot request in ec2 instance

I need a sample cloud formation template to add spot requests while provisioning the ec2 instance in AWS.I have tried with console to provision spot instances but I couldn't find any exact template for add spot request in ec2

You Can create a SpotFleet resource, here's an example

SpotFleet:
 Type: AWS::EC2::SpotFleet
 Properties:
   SpotFleetRequestConfigData:
     IamFleetRole: !GetAtt [IAMFleetRole, Arn]
     SpotPrice: '1000'
     TargetCapacity:
       Ref: TargetCapacity
     LaunchSpecifications:
     - EbsOptimized: 'false'
       InstanceType:
         Ref: InstanceType
     ImageId:
       Fn::FindInMap:
       - AWSRegionArch2AMI
       - Ref: AWS::Region
       - Fn::FindInMap:
         - AWSInstanceType2Arch
         - Ref: InstanceType
         - Arch
     SubnetId:
       Ref: Subnet1
     WeightedCapacity: '8'
   - EbsOptimized: 'true'
     InstanceType:
       Ref: InstanceType
     ImageId:
       Fn::FindInMap:
       - AWSRegionArch2AMI
       - Ref: AWS::Region
       - Fn::FindInMap:
       - AWSInstanceType2Arch
       - Ref: InstanceType
       - Arch
     Monitoring:
       Enabled: 'true'
       SecurityGroups:
        - GroupId:
            Fn::GetAtt:
            - SG0
            - GroupId
      SubnetId:
         Ref: Subnet0
      IamInstanceProfile:
        Arn:
        Fn::GetAtt:
        - RootInstanceProfile
        - Arn
      WeightedCapacity: '8'
