Install Public Extensions on ECS Instances with OOS Quick Setup - CloudOps Orchestration Service

Extensions are plug-ins that extend Elastic Compute Service (ECS) features. You can use extensions to meet your requirements. Extensions include environments (such as Java, Python, and PHP), monitoring tools (such as the CloudMonitor agent), and management tools (such as BT panel). You can install extensions for ECS instances in different regions by using the quick setup feature. The quick setup feature improves efficiency of software installation and uninstallation.

Note

This topic describes how to configure public extensions for ECS instances in different regions. For more information about how to configure a public or custom extension for an ECS instance in a region, see Extensions.

Procedure

Log on to the CloudOps Orchestration Service (OOS) console.
In the left-side navigation pane, click Quick Setup.
On the Configuration Library tab, click Create in the Extension section.

On the Extension page, specify the parameters and click Create.

The following table describes the key parameters.

Parameter		Description
Configuration Description		The description of the configuration. The description must be 1 to 256 characters in length.
Select Instances	SelectRegion	Valid options: Deploy in Current Region: applies the configuration list to the region selected in the top navigation bar of the OOS console. Deploy in Another Region: applies the configuration to the one or more regions that you select.
Select Instances	TargetInstance	Select the ECS instances based on the region type. If you set the SelectRegion parameter to Deploy in Current Region, you can set the Select Role parameter to Manually Select Instances, Specify Instance Tags, Specify Resource Group, or Select All and select one or more nodes. If you set the SelectRegion parameter to Deploy in Another Region, you can set the Select Role parameter to Specify Instance Tags or Select All and select one or more nodes.
Configure Parameters	packageName	You can select only a public extension. Supported extensions vary with the ECS instance that you select.
	Action	You can select Install, Uninstall, and Update.
	packageVersion	The extension version is selected by default. You do not need to select a version.
	Parameters	The required parameters vary with the extension you select. Note If No parameters are required for the extension is displayed, you do not need to specify additional parameters.

If you want to configure the ratio of concurrent tasks, click Control Options.

(Optional) Control Options

Rate control type:
- Concurrency-based Control: The task is run based on a specific concurrency value until the task is completed. This value is suitable if you want to control resource usage to prevent resource overutilization.
- Batch-based Control: The selected ECS instances are divided into multiple batches that sequentially run the clean-up task. This value is suitable if you want to control the execution pace, mitigate instantaneous pressure, or maintain the data processing sequence.
Concurrency: specifies the number or percentage of the selected ECS instances that concurrently run the clean-up task. In this example, this parameter is set to 1, which specifies that one of the selected ECS instances runs the clean-up task at a time.
Error Threshold: specifies the maximum number of errors that can occur before the clean-up task stops running. Enter a number or percentage. Default value: 0, which specifies that the clean-up task stops running when an error occurs. If you set this parameter to 100, the clean-up task runs to completion regardless of how many errors occur.

In the Confirm Configuration dialog box, confirm the configurations and click OK.
After you complete the settings, you can view the extension on the Configurations tab.
