# Helm at Lerian

> Lerian's Helm charts: the OCI registry, the versioning scheme, and links to the product-specific Kubernetes deployment guides.

Lerian publishes Helm charts for supported products and infrastructure components. Every chart ships through an OCI-compatible registry and follows a consistent versioning scheme. You install, upgrade, and manage each of them through the same workflow.

## Available Helm charts

***

Lerian maintains charts for the following products and components:

* [**Midaz**](/en/platform/deploy/midaz/midaz-helm-overview): Core ledger engine (installation, ingress, observability, dependencies, and upgrade guides).
* [**Reporter**](/en/platform/deploy/reporter/reporter-helm): Standalone reporting product for generating reports from Midaz data.
* [**Access Manager**](/en/platform/deploy/access-manager/access-manager-helm): Shared authentication and identity service.
* [**Console**](/en/platform/deploy/console/console-helm): Unified visual interface for Lerian products.
* [**Streaming Hub**](/en/platform/streaming-hub/operating-streaming-hub): Event delivery to your own endpoints and queues.
* [**Plugins**](/en/platform/deploy/plugins/plugins-helm-overview): Enterprise charts for Pix, Indirect Pix (BTG), Bank Transfer, and Fees.
* [**Infrastructure**](/en/platform/deploy/infrastructure/infrastructure-helm): Supporting components (OpenTelemetry Collector and Tracer).

## OCI registry

***

Docker Hub's OCI registry hosts the charts documented on these pages:

```bash theme={null}
oci://registry-1.docker.io/lerianstudio/<chart-name>
```

For example, to pull the Midaz chart:

```bash theme={null}
helm pull oci://registry-1.docker.io/lerianstudio/midaz-helm --version <version>
```

The Streaming Hub chart is the exception. Pull it from `oci://ghcr.io/lerianstudio/streaming-hub-helm`.

<Note>
  Helm 3.8 or later is required for OCI registry support.
</Note>

## Versioning scheme

***

Lerian uses [semantic versioning](https://semver.org/) for Helm chart packages:

```
{MAJOR}.{MINOR}.{PATCH}[-{prerelease}]
```

The **chart version** identifies the Helm chart package. The **app version** identifies the application container image that the chart deploys by default. The two move independently.

Read both values from the registry instead of from a document. Replace `<chart-name>` with the chart you deploy:

```bash theme={null}
helm show chart oci://registry-1.docker.io/lerianstudio/<chart-name>
```
