Helm

Package manager for Kubernetes that helps you define, install, and upgrade complex Kubernetes applications using charts. Helm uses a packaging format called charts, which are collections of files that describe a related set of Kubernetes resources. A chart repository is an HTTP server that houses an index.yaml file and packaged chart archives.

Helm publishes 3 APIs on the APIs.io network: ChartMuseum API, Charts API, and Repository API. Tagged areas include Charts, Cloud Native, Container Orchestration, DevOps, and Kubernetes.

The Helm catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.

Helm’s developer surface includes documentation, getting-started guide, engineering blog, changelog, and 11 more developer resources.
