A key link for enterprises to implement automated O&M is to quickly find multiple resources on which you want to perform O&M at a time. This can be achieved by using resource tags and Operation Orchestration Service (OOS). This topic describes how to use OOS to start multiple Elastic Compute Service (ECS) instances with specific tags at a time.

Step 1: Add tags to ECS instances

In the ECS console or on the Tag page of the Resource Management console, add the business:bigdata tag to ECS instances. In this section, the Tag page of the Resource Management console is used.

  1. Log on to the Resource Management console.
  2. In the left-side navigation pane, choose Tag > Tag.
  3. In the top navigation bar, select a region.
  4. On the Custom Tags tab, click Create Custom Tags.
  5. In the Create Custom Tags dialog box, add the business:bigdata tag to existing ECS instances.
    For more information, see Add a custom tag.

Step 2: Start multiple ECS instances with specific tags at a time in the OOS console

Execute the ACS-ECS-BulkyStartInstances public template in the OOS console. In this step, set the template execution object to ECS instances to which the business:bigdata tag is added.

  1. Log on to the OOS console.
  2. In the left-side navigation pane, click Public Templates.
  3. In the top navigation bar, select a region.
    Note By default, OOS deployed in a region can be used to manage resources only in that region. For example, OOS deployed in the China (Hangzhou) region can be used to manage ECS instances only in this region. However, OOS provides a method to manage resources deployed in other regions. If you want to call API operations in other regions, specify the region ID in the ACS::ExecuteAPI action. We recommend that you do not use this method. Make sure that the region of OOS is the same as that of the ECS instances that are specified in Step 1: Add tags to ECS instances.
  4. On the Public Templates page, find ACS-ECS-BulkyStartInstances and click Create Execution.
  5. On the Create page, perform the following operations:
    1. In the Basic Information step, keep the default values and click Next: Parameter Settings.
      The default value of Execution Mode is Automatic. This indicates that all tasks in the template will automatically run.
    2. In the Parameter Settings step, set targets to Specify Instance Tags. Select business from the Tag Key drop-down list and select bigdata from the Tag Value drop-down list. Set Permissions to Use Existing Permissions of Current Account. Keep the default values for other parameters.
    3. Click Next: OK.
    4. Confirm the settings and click Create.
  6. On the Instance List tab of the page that appears, view execution results.

    All ECS instances to which the business:bigdata tag is added are started.
