Overview

A component template is a specification file that describes ServiceStage components and defines resources (such as ConfigMaps, Secrets, and Services) and configurations required for component running.

You can use a component template to provision components, resources required for component running, and configuration files to quickly create and upgrade components.

This practice provides the component template package template-package-demo.zip and image package demo-app.tar. Table 1 describes the component template files contained in the component template package. The image package is the source of the component package for creating and deploying components and is defined by the image field in the deployment.yaml file in Table 1.

For details, see Component Template Description.
