Suspend autoscaling processes through Cloudformation template

Question

I have the following autoscaling as a Cloudformation template :

  MyAutoScalingGroup:
    Type: AWS::AutoScaling::AutoScalingGroup
    Properties:
      DesiredCapacity: 1
      MinSize: 1
      MaxSize: 1
      LaunchConfigurationName: !Ref MyLaunchConfiguration
      AvailabilityZones: !GetAZs

I am struggling with defining suspended processes inside Cloudformation template.

Trying an intuitive approach ( adding it as property) and it does not work at all :

  MyAutoScalingGroup:
    Type: AWS::AutoScaling::AutoScalingGroup
    Properties:
      DesiredCapacity: 1
      MinSize: 1
      MaxSize: 1
      LaunchConfigurationName: !Ref MyLaunchConfiguration
      AvailabilityZones: !GetAZs
      SuspendedProcesses:
        - AZRebalance
        - Terminate

Answer 1

Got it from official documentation of UpdatePolicy . Indeed, we can suspend processes by using the UpdatePolicy attribute for the AWS::AutoScaling::AutoScalingGroup resource :

• So instead of SuspendedProcesses, the right term is SuspendProcesses.

• Also instead of putting SuspendProcesses under Properties, it should be under UpdatePolicy > AutoScalingRollingUpdate .

      LaunchConfigurationName: !Ref MyLaunchConfiguration
      AvailabilityZones: !GetAZs
    UpdatePolicy:
