具有 Spot 实例的 CloudFormation LaunchTemplate AutoScaling 组

Question

I'm creating a CloudFormation template to deploy an autoscaling group that should only use spot instances. The Cloudformation throws an error with this template. What's wrong here?

Error: CREATE_FAILED Encountered unsupported property InstancesDistribution

 { "Resources": { "testasg": { "Type": "AWS::AutoScaling::AutoScalingGroup", "Properties": { "LaunchTemplate": { "LaunchTemplateId": "lt-0c8090cd4510eb25e", "Version": "1" }, "MaxSize": "10", "MinSize": "2", "DesiredCapacity": "2", "VPCZoneIdentifier": [ "subnet1", "subnet2" ], "MaxInstanceLifetime": 86400, "InstancesDistribution": { "OnDemandAllocationStrategy": "lowest-price", "OnDemandBaseCapacity": 0, "OnDemandPercentageAboveBaseCapacity": 0, "SpotAllocationStrategy": "lowest-price", "SpotInstancePools": 2 }, "NewInstancesProtectedFromScaleIn": false, "TerminationPolicies": [ "OldestInstance" ], "Tags": [ { "Key": "Cluster", "Value": "Production", "PropagateAtLaunch": "true" }, ] } } } }

Answer 1

InstancesDistribution should be inside MixedInstancesPolicy block, which you do not have.
