Helm uses templated YAML files, allowing you to define reusable, parameterized Kubernetes manifests. Instead of writing complex YAML files over and over, you create a chart once and reuse it with different values.
Helm allows you to version your application deployments, making it easier to roll forward or backward in case of issues. You can upgrade or rollback releases with a single command.
Helm supports dependencies between charts. If your application depends on Redis or PostgreSQL, you can include them as subcharts instead of manually managing each one.
Each deployment with Helm is a release. Helm tracks releases, so you can inspect or revert to previous states, which helps in troubleshooting or auditing changes.
Helm charts make it easy to share applications. Public repositories like Artifact Hub or private chart repos let teams distribute complex applications without needing others to understand every YAML detail.
Using Helm, you can deploy the same application in dev, staging, and production with different configurations—ensuring consistency with flexibility.
