How to use feature flags to lower risk in deployments

The tutorial delves into the use of feature flags as a progressive delivery technique in continuous delivery (CD), aimed at reducing deployment risks by allowing developers to perform controlled testing in production environments. Feature flags enable developers to specify which features are deployed and to whom, facilitating experimentation without affecting all users. The guide illustrates the implementation of feature flags using GitLab, involving steps to set up a Kubernetes cluster, import and manage projects, and configure feature flags for different environments. It highlights the benefits of feature flags such as lower risk, ease of use, and enhanced compliance through audit capabilities. The tutorial includes a practical segment using a fictitious inventory management application, demonstrating how to create, configure, and apply feature flags, followed by testing these flags in both staging and production environments to ensure functionality. It emphasizes the importance of audit events in tracking changes to feature flags for compliance and risk management, ultimately offering a comprehensive approach to deploying updates with minimized risk.
