Flagger is a progressive delivery tool designed specifically for Kubernetes applications. It automates the release process by gradually shifting traffic from an old version of your application to a new one while measuring key metrics and running conformance tests. This helps minimize the risk of introducing production issues and ensures a smooth and controlled rollout.

Key Features:

• Multiple Deployment Strategies: Supports Canary releases, A/B testing, Blue/Green deployments, and Feature Gates, offering flexibility for different scenarios.

• Integration with Various Metrics Sources: Collects and analyzes metrics from Prometheus, Grafana, Datadog, and other popular providers.

• Automated Rollbacks: Automatically rolls back deployments if they trigger predefined rollback conditions.

• GitOps-Based Configuration: Manages deployments using familiar GitOps principles for consistency and reproducibility.

• Extensible Architecture: Integrates with other tools and services through plugins and APIs.

Benefits of Using Flagger:

• Reduced Risk of Deployments: Mitigates the risk of introducing new bugs or regressions by gradually rolling out changes.

• Improved Release Velocity: Streamlines the release process by automating deployments and rollbacks.

• Enhanced Observability: Gains insights into application performance and health during deployments.
