SSM Patch Manager LifeCycleHooks to remove node from TargetGroup
Working with AWS SSM to automate the patching of EC2 instances that are part of a target group. As patching will be carried out on live instances without any application downtime, we would like to cleanly remove the EC2 from the target group by de-registering them first and re-register pre and post reboot and patching.
Can this be achieved using say a SSM RunCommand as part of the Patching lifecycle hooks (PreInstall etc) or is there a better method?

Maybe the following Automation runbook provided by AWS will fit your use case.
https://docs.aws.amazon.com/systems-manager-automation-runbooks/latest/userguide/automation-awsec2-patch-load-balancer-instance.html
- The load balancer or target group to which the instance is attached is determined, and the instance is verified as healthy.
- The instance is removed from the load balancer or target group.
- The automation waits for the period of time specified for the connection draining time.
- The AWS-RunPatchBaseline automation is called to patch the instance.
- The instance is reattached to the load balancer or target group.
