Serverless App Engine:Deploy an application in a single batch

Prerequisites

The application is running.

Procedure

1. On the SAE Application List page, select a region and namespace at the top, and click the ID of the target application to open the application details page.

2. On the Basic Information page, click Deploy Application.

3. Configure deployment parameters.

   Note

   The deployment method of an application is based on the deployment method that you selected for the application for the first time. Configure the parameters based on the selected method.

   • Deployment with WAR Packages: Upload another WAR package or enter the path of a newly deployed WAR package, and configure the runtime environment and other settings.

   • Deployment with JAR Packages: Upload another JAR package or enter the path of a newly deployed JAR package, and configure the runtime environment and other settings.

   • Deployment with ZIP Packages: Upload another ZIP package or enter the path of a newly deployed ZIP package, and configure the runtime environment and other settings.

   • Image: In the Configure Image section, click Modify Image. In the Modify Image panel, select another image repository or image version.

4. In the Release Policy Settings section, set Minimum Available Instances.

   • By Number: Enter the minimum number of available instances.

   • By Ratio: Enter a percentage. You can also select Use System Recommended Value.

   Note

   • Make sure that at least one instance is available during application deployment and rollback. This ensures business continuity. If you set the value to 0, business interruptions occur when the application is upgraded.

   • If you specify a percentage, the minimum number of available instances is rounded up to the nearest integer. For example, five instances are available and you specify 25%. In this case, the minimum number of available instances is 2.

5. Optional:Configure the following advanced settings as needed.
