Helm Chart

Type Name

helmChart

Description

A Kubernetes installation resource representing a Helm chart, either stored as OCI artifact or as tar blob.

Format Variants

  • OCI Artifact

    A Helm chart might be stored as OCI artifact following the Artifact Set Archive Format. This format is for example provided by the access method type ociArtifact

    Media types:

    • application/vnd.oci.image.manifest.v1+tar
    • application/vnd.oci.image.manifest.v1+tar+gzip

    The config blob media type described in the OCI manifest MUST be

    • application/vnd.cncf.helm.config.v1+json

  • Helm Tar Archive

    If stored in the Helm tar format (for the filesystem), the tar media type MUST be used.

    Media types:

    • application/vnd.cncf.helm.chart.content.v1.tar
    • application/vnd.cncf.helm.chart.content.v1.tar+gzip

Special Support

There is a dedicated downloader available, that always converts the Helm chart blob into the appropriate filesystem representation required by Helm when downloading the artifact using the command line interface.
