Question

Your team's Azure Pipelines YAML build runs unit tests successfully, but integration tests fail because they require a running Redis instance. The tests connect to Redis on localhost:6379. You want the dependency to start automatically for the duration of the job on the Microsoft-hosted Linux agent, without maintaining a separate persistent server or writing custom startup scripts. What should you configure in the pipeline?

Accepted Answer

Define a container resource under 'resources.containers' and reference it in the job's 'services' section so Redis runs as a service container.

Answer

Add a 'DockerInstaller@0' task followed by a script step that runs 'docker run -d redis' before the test step.

Answer

Configure a deployment job with an 'environment' that has a Redis virtual machine resource registered.

Answer

Use a matrix strategy to run the tests across multiple Redis versions installed via a package manager.
