Charts as OCI Artifacts
Modern Helm can store charts in the same registries that hold container images. These are OCI registries, and they need no index.yaml.
Why OCI Over Classic Repos
An OCI registry reuses your existing image infrastructure: one place, one auth model, built-in versioning. No separate static host to maintain.
Stable Since Helm 3.8
OCI support became a stable, default feature in Helm 3.8. On current versions you can push and pull charts with no extra setup flags.
Log In First
Pushing requires credentials. Use helm registry login with the registry host, just as you would authenticate a container registry.
helm registry login ghcr.io -u myuserPackage, Then Push
You still package the chart into a .tgz first. Then helm push uploads that archive to your registry path.
helm package ./mychart
helm push mychart-0.2.0.tgz oci://ghcr.io/myorgThe oci:// Prefix
OCI locations always start with the oci:// scheme. Helm uses it to know the target is a registry, not a classic HTTP chart repo.
oci://ghcr.io/myorgThe Tag Is the Version
Helm pushes the chart under a reference whose tag equals the Chart.yaml version. The chart name becomes the final path segment.
oci://ghcr.io/myorg/mychart:0.2.0Installing From OCI
To install, give the full oci:// reference and pick the version with --version. No helm repo add step is needed.
helm install web oci://ghcr.io/myorg/mychart --version 0.2.0Pulling an OCI Chart
You can also download the archive without installing using helm pull against the OCI reference, handy for inspection or mirroring.
helm pull oci://ghcr.io/myorg/mychart --version 0.2.0Show Values Works Too
OCI references plug into the usual commands. helm show values on an oci:// path lets you read defaults before installing.
helm show values oci://ghcr.io/myorg/mychart --version 0.2.0No Index to Maintain
The big win: with OCI there is no index.yaml to rebuild. The registry tracks versions, so publishing is just package and push.

Recap: Pushing to OCI
You logged in, packaged, and used helm push with the oci:// scheme to publish a chart, then installed it by reference. No index needed. 🚀
