helm

Create a Helm chart using `helm create`, define your application in Chart.yaml and values.yaml, write Go templates for Kubernetes resources, then deploy with `helm install`. Helm automates packaging and templating, ensuring consistent deployments across clusters.

Helm charts package templates, values, and metadata for reusable, versioned deployments with built-in upgrade and rollback capabilities. Direct manifests require manual templating and version management, making Helm preferable for multi-environment consistency.

Use `helm upgrade` to apply new chart versions or values to existing releases, `helm get` to inspect deployment status and history, and `helm rollback` to revert failed upgrades. Helm tracks release state across environments automatically.

Yes—use `helm lint` to validate chart syntax and structure, and `helm template` to preview rendered manifests without installing. `helm get` and dry-run flags let you verify deployments before applying to the cluster.

Yes, Helm uses Go template syntax for dynamic resource generation in chart templates. Basic templating covers loops, conditionals, and variable substitution; the metadata supports full template development and rendering.

Define environment-specific values in separate files (e.g., values-prod.yaml, values-staging.yaml) and pass them during `helm install` or `helm upgrade`. Helm merges values dynamically, enabling repeatable deployments across multi-environment clusters.
