# Helm at Lerian

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

Lerian publishes Helm charts for all of its products and infrastructure components. Every chart is distributed through an OCI-compatible registry and follows a consistent versioning scheme, so you can install, upgrade, and manage any Lerian component with the same workflow.

## Available Helm charts

***

Lerian maintains charts for the following products and components:

* [**Midaz**](/en/platform/helm/midaz/midaz-helm-overview): Core ledger engine — installation, ingress, observability, dependencies, and upgrade guides.
* [**Reporter**](/en/platform/helm/reporter/reporter-helm): Standalone reporting product for generating reports from Midaz data.
* [**Access Manager**](/en/platform/helm/access-manager/access-manager-helm): Shared authentication and identity service.
* [**Console**](/en/platform/helm/console/console-helm): Unified visual interface for Lerian products.
* [**Plugins**](/en/platform/helm/plugins/plugins-helm-overview): Enterprise plugins — CRM, Fees Engine, Pix, Pix Indirect (BTG), and Bank Transfer.
* [**Infrastructure**](/en/platform/helm/infrastructure/infrastructure-helm): Supporting components — OTEL Collector, Fetcher, Flowker, Tracer, and Underwriter.

## OCI registry

***

All Lerian Helm charts are hosted on Docker Hub's OCI registry:

```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>
```

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

## Versioning scheme

***

Lerian uses a **prefixed semantic versioning** scheme for Helm charts:

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

**Examples:**

* `midaz-v5.7.0` — Midaz Helm chart version 5.7.0
* `plugin-crm-v4.0.0` — CRM plugin chart version 4.0.0
* `reporter-v2.0.0` — Reporter chart version 2.0.0

The **Chart version** refers to the Helm chart package version. The **App version** refers to the actual application container image version deployed by the chart.

For the full compatibility matrix across all products, see [Version compatibility](/en/platform/helm/helm-version-compatibility).
