      - Deploying a simple web application
        In this tutorial, you deploy a simple web application with HCL DevOps Deploy (Deploy). You create components, create an application that contains those components, and then deploy the components to an environment.
      - Creating and deploying snapshots
        In this tutorial, you deploy a simple web application to a new environment with HCL DevOps Deploy (Deploy). You create a snapshot of the components in an application, and then deploy the snapshot to an environment.
        Introduction
        In this tutorial, you deploy a simple web application to a new environment with HCL DevOps Deploy (Deploy). You create a snapshot of the components in an application, and then deploy the snapshot to an environment.
        Configuring the server and target system
        Modify the HCL DevOps Deploy (Deploy) server that you used in the previous tutorial. Create another agent resource and incorporate a new environment property to allow for easy reuse.
        Lesson 1: Adding snapshots
        Creating a snapshot involves saving a collection of component versions that are part of an application.
        Lesson 2: Creating an environment
        Environments are deployment targets for the application components that you specify. You create another environment in the application's delivery pipeline to facilitate multiple active applications. You apply an agent resource and specify which components the agent resource deploys.
        Lesson 3: Deploying the snapshots
        To promote the snapshot to an environment, apply the snapshot when you run the application process.
        Summary
        In this tutorial, you created and deployed a snapshot to an environment in HCL DevOps Deploy (Deploy).

Lesson 3: Deploying the snapshots

To promote the snapshot to an environment, apply the snapshot when you run the application process.

About this task

In this lesson, you apply a snapshot to your new environment to quickly promote the components to a new environment. When you request the application process, you select the snapshot to deploy a selected set of components to an environment.

Procedure

Open the application page by clicking Applications and then clicking JPetStore.
In the same row as your new environment, click the Request Process icon, as shown in the following figure.
In the Run Process window, in the Process list, select the Deploy JPetStore process.
In the Snapshot list, select the Version 1.1 snapshot.
Click Submit.

Results

The web page shows you the progress of the application process request, and you can watch as the processes run. If the process finishes, the request shows that each component process is finished, as in the following figure:
The log for the application process request, showing that the component processes ran successfully

You can view the running application at the following URL by substituting the host name of your target system for hostname. This is the host name of the agent that you configured in Configuring the agent and target system. In the URL, specify the tomcat.contextroot value that you entered for this environment after the port number.

http://hostname:8081/JPetStoreProd

The application shows a simple online shopping site in the form of a pet store. The following figure shows the home page:

If you browse to the Dogs category, you see that the Bichon section is present. As you saw in the previous tutorial, this entry indicates that the JPetStore-DB component deployed both the 1.0 and 1.1 versions.

What to do next

This application process installed all components in the application by running their component processes. You defined the versions of the component processes in the snapshot.

You used a snapshot to quickly apply a compatible set of component processes to an application environment and viewed the deployed web page.
