This topic describes how to view the Elastic Compute Service (ECS) instances or elastic container instances in a scaling group.

Procedure

  1. Log on to the Auto Scaling console.
  2. In the left-side navigation pane, click Scaling Groups.
  3. In the top navigation bar, select a region.
  4. Find a scaling group and go to the details page of the scaling group. You can use one of the following methods to go to the details page:
    • Click the ID of the scaling group in the Scaling Group Name/ID column.
    • Click Details in the Actions column of the scaling group.
  5. In the upper part of the page, click the Instances tab.
  6. View the ECS instances or elastic container instances in the scaling group.
    You can change the status of ECS instances that are manually added and automatically created. For example, you can manually put an ECS instance into the Standby state or the Protected state. You can also remove an ECS instance from your scaling group or release the ECS instance.
    • On the Auto Created tab, you can view the ECS instances or elastic container instances that are automatically created in the scaling group. If the system considers an ECS instance or elastic container instance unhealthy, the unhealthy instance is automatically removed from the scaling group and released.
    • On the Manually Added tab, you can view the ECS instances that are manually added to the scaling group. You cannot manually add elastic container instances to scaling groups.

      If a manually added instance is not in the Running state, the instance is considered unhealthy and removed from the scaling group. Whether an ECS instance is released when it is removed from the scaling group is determined by its management mode.

      • If the lifecycle of the instance is not managed by the scaling group, the instance is not released when it is removed from the scaling group.
      • If the lifecycle of the instance is managed by the scaling group, the instance is released when it is removed from the scaling group.
