Pipeline Configuration for Template1.yml and File1.yml

C

Azure Pipelines offers two kinds of templates: includes and extends. Included templates behave like #include in C++: it's as if you paste the template's code right into the outer file, which references it. To continue the C++ metaphor, extends templates are more like inheritance: the template provides the outer structure of the pipeline and a set of places where the template consumer can make targeted alterations.

Example:

extends:

template: template.yml@templates

parameters:

usersteps:

- script: echo This is my first step

- script: echo This is my second step

The correct answer is B:

yamlCopy code
template: template1.yml  parameters:    usersteps:    - task: MyTask@1    - script: echo Done 

Explanation:

In Azure DevOps, pipelines can be created using YAML, and YAML templates can be used to define reusable parts of a pipeline. In this scenario, the YAML template Template1.yml defines a sequence of steps to be executed in the pipeline, and the pipeline File1.yml contains a parameterized list of steps that need to be executed.

To ensure that Template1.yml runs before File1.yml, we need to include the reference to the template in the pipeline YAML file using the template keyword, followed by the name of the YAML file that contains the template (template1.yml). The parameters keyword should then be used to specify the parameters required by the template, which in this case is the usersteps parameter. The usersteps parameter is an array that contains the steps to be executed after the steps defined in the template.

Option A is incorrect because extends is not a valid keyword to include a YAML template in a pipeline. The correct keyword is template.

Option C is incorrect because the extends keyword is not used to include a YAML template in a pipeline, and there is a typo in the filename of the template (templatel.yml instead of template1.yml).

Option D is incorrect because the template keyword is used inside the usersteps parameter instead of being used directly in the pipeline YAML file. Additionally, there is a typo in the filename of the template (templatel.yml instead of template1.yml).
