Last updated: 2020-06-23 14:52:08

    A scaling group contains a collection of CVM instances that follow the same policies and have a shared purpose.

    Creating a Scaling Group

    1. Log in to Auto Scaling Console and click Scaling group(https://console.cloud.tencent.com/autoscaling/group) in the left sidebar.
    2. Select a region and click **Create” on the top of the scaling group list.
    3. In Create scaling group pop-up, complete the basic configurations. Fields marked with are required, as shown below:
      • A scaling group maintains the number of CVM instances to meet the desired capacity between the minimum and maximum capacity values.
      • The starting instance quantity defines the default number of CVM instances in the scaling group.
        • If a scaling group has a number of CVM instances fewer than the minimum scaling capacity value, it will automatically add instances to meet the minimum condition.
        • If a scaling group has a number of CVM instances greater than the maximum scaling capacity value, it will automatically terminate instances until the number of instances is equal to the maximum value allowed.
      • Select an existing launch configuration or create one.
      • Select the network, availability zone, and removal policy.
      • (Optional) Associate with an existing CLB instance or create one.
    4. After the configuration is completed, you will see this entry on the scaling group list, as shown below:

    Adding an Instance (optional)

    3. In "Add Instances" pop-up, select instances to add to the scaling group.
    4. Click OK to complete the configuration.
      You will see the added instances on the launch configuration list.
