This section describes how to deploy static components in the corresponding environment.

When creating an application component, you can also select Create and Deploy. The deployment procedure is the same as that described in this section.

Prerequisites

An application component has been created or is being created, and has been configured. For details, see Creating an Application Component.
The environment has been created. For details, see Environment Management.
If you deploy components based on software packages or image packages, you need to upload the software packages or image packages.
- Upload the software package to the OBS bucket. For details, see Uploading a File.
- Upload the image package to the image repository. For details, see Uploading an Image.

Procedure

Log in to ServiceStage and choose Application Management > Application List.
Click an application. The Overview page is displayed.
On the Component List tab, select a component and click Deploy in the Operation column.

Set basic parameters. Parameters marked with an asterisk (*) are mandatory.

Parameter	Description
*Environment	Select an environment.
*Version	Component version number, for example, 1.0.0.
Description	Description of the component.
*Deployment System	Supports Cloud Container Engine and VM. For details, see Deployment Mode.
*Resource Type	This parameter takes effect only when VM is selected for Deployment System. You can select Elastic cloud server.
*Basic Resource	The basic resources contained in the selected environment are automatically loaded. Select the resources as required.
*Instances	Number of instances in an application component. An application component can have one or more instances. You can specify the number of instances as required. Configuring multiple instances for an application component ensures high reliability of the application component. For such a component, if an instance is faulty, the component can still run properly. NOTE: This parameter is invalid when VM is selected for Deployment System. The number of component instances is determined by the number of Basic Resources. When the quota for the number of microservice instances specified by the engine specifications is about to be used up, the engine allows component deployment operations that exceed the remaining quota to succeed at the same time to ensure availability. Expand the capacity of the engine as soon as possible to prevent component deployment failures.
*Resource Quota	Components cannot be scheduled to nodes whose residual resources are fewer than the requested amount. For details about how to configure the request and limit parameters, see Managing Resources for Containers. You can customize CPU and Memory as required. NOTE: This parameter is not displayed when the component type is Common and the runtime system is Docker. This parameter is invalid when VM is selected for Deployment System.
Component Status	Sets the component status as required. NOTE: This parameter is available when the component type is Common, the runtime system is Docker, and Cloud Container Engine is selected for Deployment System.

Click Next to configure the component.
