Test the application to ensure you get the results you expect.
Estimated time to complete Step 7 and finish tutorial: 5 minutes.
Before testing your application, verify that you completed the tasks in the previous tutorial steps. Using the DuploCloud Portal, confirm that:
An Infrastructure and Plan exist, both named NONPROD.
A Tenant named dev01 has been created.
An EC2 Host named host01 has been created.
A Service named demo-service-d01 has been created.
A Load Balancer has been created.
In the Tenant list box, select dev01.
Navigate to Docker -> Services. The Services page displays.
From the Name column, select demo-service-d01.
Click the Load Balancers tab. The Application Load Balancer configuration is displayed.
In the DNS status card on the right side of the Portal, click the Copy Icon ( ) to copy the DNS address displayed to your clipboard.
Open a browser instance and paste the DNS in the URL field of your browser.
Press ENTER. A web page with the text Hello World! is displayed, from the JavaScript program residing in your Docker Container running in demo-service-d01, which is exposed to the web by your Load Balancer.
It can take from five to fifteen (5-15) minutes for the DNS Name to become active once you launch your browser instance to test your application.
Congratulations! You have just launched your first web service on DuploCloud!
In this tutorial, your objective was to create a cloud environment to deploy an application for testing purposes, and to understand how the various components of DuploCloud work together.
The application rendered a simple web page with text, coded in JavaScript, from software application code residing in a Docker container. You can use this same procedure to deploy much more complex cloud applications.
In the previous steps, you:
Created a DuploCloud Infrastructure named NONPROD, a Virtual Private Cloud instance, backed by an AKS-enabled Kubernetes cluster.
Created a Tenant named dev01 in Infrastructure NONPROD. While generating the Infrastructure, DuploCloud created a set of templates (Plan) to configure multiple Azure and Kubernetes components needed for your environment.
Created an EC2 host named host01, so your application has storage resources.
Created a Service named demo-service-d01 to connect the Docker containers and associated images, in which your application code resides, to the DuploCloud Tenant environment.
Created an ALB Load Balancer Listener to expose your application via ports and backend network configurations.
Verified that your web page rendered as expected by testing the DNS Name exposed by the Load Balancer Listener.
In this tutorial, you created many artifacts for testing purposes. Clean them up so others can run this tutorial using the same names for Infrastructure and Tenant.
To delete the dev01 tenant follow these instructions, then return to this page. As you learned, the Tenant segregates all work in one isolated environment, so deleting the Tenant that you created cleans up most of your artifacts.
The NONPROD Infrastructure is deleted and you have completed the clean-up of your test environment.
Thanks for completing this tutorial and proceed to the next section to learn more about using DuploCloud with AWS.
Finish by deleting the NONPROD Infrastructure. In the DuploCloud Portal, navigate to Administrator -> Infrastructure. Click the Action menu icon () for the NONPROD row and select Delete.
