In order to support various unique functions for different cloud providers, we provide add-ons.


The ALM-agent enables you to perform specific actions when Auto Scaling Instances or Spot Instances are terminated.

How ALM Agent Works

  • Deregisters the instance from the load balancer.

    • After the instance is deregistered, it no longer receives traffic from the load balancer.

  • Executes the specified script.

    • If you put the script named under the root (/) folder in the Docker Image, the ALM-agent executes the script.


  • Auto Scaling puts the instance into Terminating:Wait.

  • Amazon EC2 will interrupt Spot Instances.
