Helm chart
A Helm chart is a versioned package of templated Kubernetes resource definitions, configuration values, and metadata for deploying an application or service.
Platform Engineering on Kubernetes
A Helm chart is a package of templated Kubernetes resource definitions and metadata for installing an application or service.
- How it is used
- Packages applications and infrastructure for installation as named releases in Kubernetes clusters.
- How deep it goes
- Demonstrates installation, release inspection, YAML rendering, and deployment choices, while deferring how deployable packages are produced.
- Examples
- Uses a Conference application chart and PostgreSQL, Redis, and Kafka infrastructure charts.
- What you can do after
- Operate/configure it by installing a chart, listing releases, or rendering YAML for changes before deployment.

A Helm chart is a packaged collection of Kubernetes resource templates and configuration values used to define an application deployment.
- How it is used
- Packages related Kubernetes objects into a customizable application deployment instead of managing each object file separately.
- How deep it goes
- Defines templates and values, then walks through chart creation, installation, inspection, and CI/CD integration without detailing template syntax.
- Examples
- Uses a Redis chart, a three-replica application chart, and a Service-type edit detected by Argo CD.
- What you can do after
- Operate/configure it by setting chart values, installing and inspecting releases, and connecting chart updates to GitLab CI and Argo CD.

A Helm chart is a package of templates and configuration that describes how to install an application and its Kubernetes resources.
- How it is used
- Deploys Kubernetes applications from reusable packages while allowing administrators to customize templated manifests.
- How deep it goes
- Explains repositories, chart search, values files, installation, and release verification, but does not detail chart structure or template syntax.
- Examples
- Uses HashiCorp Vault and MetalLB searches, a MetalLB values.yaml installation, and helm ls output for verification.
- What you can do after
- Operate/configure Helm to find repositories, customize a chart, install an application, and verify its deployed release.
