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:

You need to create Spot-fleet resource.
Example :
"SpotFleet": {
"Type": "AWS::EC2::SpotFleet",
"Properties": {
"SpotFleetRequestConfigData": {
"IamFleetRole": { "Fn::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"
}
]
}
}
}
