[Helm](https://helm.sh) is a package manager for [Kubernetes](https://kubernetes.io). Helm uses a packaging format called [charts](https://docs.helm.sh/developing_charts). Since version 1.6.0 Harbor is now a composite cloud-native registry which supports both container image management and Helm charts management. Access to Helm charts in Harbor is controlled by [role-based access controls (RBAC)](https://en.wikipedia.org/wiki/Role-based_access_control) and is restricted by projects.
## Manage Helm Charts via the Harbor Interface
There are two places to manage helm charts. First one is in the ChartMuseum which is provided by Harbor from version 1.6.0. The second one is in the OCI-compatible registry which is provided by Harbor from version 2.0.0. This means you can now manage Helm charts alongside your container images through the same set of projects and repositories.

## Manage Helm Charts with the OCI-compatible registry of Harbor
Helm 3 now supports registry operations for an OCI-compatible registry including pushing and pulling. To install the latest Helm CLI, please refer [install helm](https://helm.sh/docs/intro/install/). Please also run `helm version` command to make sure the version of Helm CLI is v3.0.0+.
```sh
helm version
#version.BuildInfo{Version:"v3.2.1", GitCommit:"fe51cd1e31e6a202cba7dead9552a6d418ded79a", GitTreeState:"clean", GoVersion:"go1.13.10"}
```
### Login to the OCI-compatible registry of Harbor
Before pull/push helm charts with the OCI-compatible registry of Harbor, Harbor should be logged with `helm registry login` command.
```sh
helm registry login xx.xx.xx.xx
```
{{< note >}}
The CA file used by the Harbor is necessary to be trusted in the system due to an [issue](https://github.com/helm/helm/issues/6324) in Helm.
{{< /note >}}
### Push Charts to the artifact Repository with the CLI
After logging in, run the `helm chart save` command to save a chart directory which will prepare the artifact for the pushing.
```sh
helm chart save dummy-chart xx.xx.xx.xx/library/dummy-chart
```
When the chart was saved run the `helm chart push` command to push your charts:
```sh
helm chart push xx.xx.xx.xx/library/dummy-chart:version
```
### Pull Charts from the artifact Repository with the CLI
To pull charts from the the OCI-compatible registry of Harbor, run the `helm chart pull` command just like pulling image via docker cli.
```sh
helm chart pull xx.xx.xx.xx/library/dummy-chart:version
```
### Manage Helm Charts artifacts in Harbor Interface
The charts pushed to the OCI-compatible registry of Harbor are treated like any other type of artifact. We can list, copy, delete, update labels, get details, add or remove tags for them just like we can for container images.
