Question

How do you implement feature flags in a Jenkins pipeline to control feature rollouts? Can you provide an example of dynamically toggling features during a deployment?

This question delves into using feature flags in Jenkins pipelines to enable or disable application features dynamically during deployments. It aims to understand how feature flags are integrated with pipelines to facilitate controlled rollouts, testing, or experimentation without redeploying the entire application.

Answer 1

Feature flags allow selective enabling/disabling of features without redeployment. To implement:

Store feature flag configurations in a centralized service, such as LaunchDarkly, or a config file.
Dynamically retrieve the feature flags during pipeline execution.
Use conditional steps in the pipeline, based on feature flag states.
