Helm charts package Kubernetes manifests into reusable, versioned units by defining Chart.yaml metadata, values.yaml configurations, and templates. You create a chart, customize values, and install it to deploy your application suite across clusters.

Helm charts support dependency management for multi-service deployments by defining dependent charts in Chart.yaml. This lets you deploy a full application suite—such as api, web, and sso services—with consistent configuration and managed dependency resolution.

Helm handles environment-specific overrides across clusters using values.yaml files. You define base configurations and provide custom values for dev, staging, and production environments, allowing templated configurations to adapt per deployment target without modifying templates.

Helm chart templating turns Kubernetes manifests into reusable, parameterized templates using Go template syntax. Templates reference values from values.yaml, enabling dynamic resource generation and helper templates to produce customized manifests for different deployment scenarios.

Helm charts require a Kubernetes cluster to install and deploy applications, as they package Kubernetes resources like deployments, services, and configmaps. The charts define manifests targeting Kubernetes APIs, so a running cluster is the prerequisite environment for deployment.

Helm charts focus on packaging and deploying Kubernetes manifests but do not manage cluster infrastructure or runtime state. Complex rolling updates and stateful application lifecycle management may require additional Kubernetes operators or manual intervention beyond chart templating capabilities.
