Azure DevOps CI Pipeline Setup

I want a clean, fully-automated Continuous Integration pipeline in Azure DevOps written entirely in YAML. The repository already lives in Azure Repos; what I’m missing is the pipeline logic that will detect every push or pull request, build the code, run unit tests, and package the result as a Docker image so I can publish it to my registry in the next stage.

You’ll translate those steps into a single, well-structured yml file, add any necessary service connections, and confirm the build works end-to-end on a fresh branch.

Deliverables
• azure-pipelines.yml with clear comments
• Any variable-group or service-connection instructions needed for Docker integration
• A brief markdown note explaining how to trigger or tweak the build

If the build passes on the first run and the Docker image appears in the registry, we’re done.
