You develop an ASP.NET Core microservice on a Windows Docker image. The code for this resides in a
VSTS Git repository.
You create an Azure Service Fabric cluster connection. Your build engineer requires that all continuous
integration build definitions must be approved before release definitions are created.
You need to enable continuous integration for the microservice.
Which three actions should you perform in sequence? To answer, move the appropriate actions from the list of
actions to answer area and arrange them in the correct order.

You need to enable continuous integration for the microservice.
Which three actions should you perform in sequence? To answer, move the appropriate actions from the list of
actions to answer area and arrange them in the correct order.
Correct Answer:
Explanation
Step 1: Enable the Continuous Integration trigger
To make sure that DevOps picks up new commits and builds them, go to the Triggers tab and enable the
Enable continuous integration checkbox.
Step 2: Create a build definition by using the Service Fabric Application template
Developers and testers can easily and quickly provision production-like dev and test environments based on
Docker by using templates from Azure.
Step 3: Add a task with the command "docker deploy" in the build definition
Thanks to the Microsoft VSTS Docker Deploy task shown in figure, you can now also deploy to DC/OS by
just using your familiar docker-compose.yml file because Microsoft will be performing that "translation" for
you (from your docker-compose.yml file to other formats needed by DC/OS).
