Helm charts package Kubernetes manifests with templating to manage dev, staging, and prod environments. Create a Chart.yaml, values.yaml for each environment, and templates/ directory with manifest files. Use environment-specific values overrides to customize deployments without duplicating chart code.

Helm supports umbrella charts that declare dependencies on subchart services. Define each service as a dependency in Chart.yaml, manage shared and service-specific values in values.yaml, and use templating to inject configuration into each subchart, enabling centralized multi-service orchestration.

Yes, Helm supports publishing packaged charts to OCI registries and Artifact Hub. Package your chart with `helm package`, then push using registry credentials. This enables versioned, discoverable chart distribution and simplified installation across teams and environments.

Use `helm template` to render charts locally without applying changes, validating YAML syntax and template output before production deployment. This lets you inspect generated manifests, test environment-specific values, and catch configuration errors safely.

A single chart with environment-specific values.yaml files is the standard approach. Use values overrides for dev, staging, and prod configurations, keeping chart structure and templates consistent while varying deployment parameters per environment.

Umbrella charts coordinate multiple subcharts via Chart.yaml dependencies and a root values.yaml that configures all services. Subcharts live in charts/ with their own Chart.yaml and templates. This structure centralizes deployment logic while maintaining service modularity.
