Use public extensions
Go to the ECS Console - Application Management page. On the My Applications tab, click the name of the target application to open the application details page.
On the application details page, click the Application Group tab. Find the target application group and click O&M.
In the O&M Operations area, click ACS-ECS-BulkyConfigureOOSPackageWithTemporaryURL. In the search box, enter a keyword, such as
Docker, to search for an extension, and then click Next. Finally, click Create.Public extensions provide commonly used components and environments. If these extensions meet your needs, you can select and install them directly. Otherwise, use custom extensions to perform a custom installation.
