# Helm

We provide several Helm charts.

* `seldon-core-v2-crds` : cluster wide install of custom resources.
* `seldon-core-v2-setup` : installation of the manager to manage resources in the namespace\
  or clusterwide. This also installs default **SeldonConfig** and **ServerConfig** resources\
  which allow Runtimes and Servers to be installed easily on demand.
* `seldon-core-v2-runtime` : this installs a **SeldonRuntime** custom resource which creates\
  the core components in a namespace.
* `seldon-core-v2-servers` : this installs **Server** custom resources which provide example\
  core servers to load models.
* `seldon-core-v2-certs` : a default set of certificates for TLS.

The Helm charts can be found within the `k8s/helm-charts` folder and they are published[here](https://github.com/SeldonIO/helm-charts)

Assuming you have installed any ecosystem components: Jaeger, Prometheus, Kafka as discussed[here](/seldon-core-2/v2.8/getting-started/kubernetes-installation.md) you can follow the following steps.

Note that for Kafka follow the steps discussed [here](/seldon-core-2/v2.8/kubernetes/kafka.md)

## Add Seldon Core 2 Charts

```bash
helm repo add seldon-charts https://seldonio.github.io/helm-charts
helm repo update seldon-charts
```

## Install the CRDs

```bash
helm install seldon-core-v2-crds  seldon-charts/seldon-core-v2-crds
```

## Install the Seldon Core 2 Components

You can install into any namespace. For illustration we will use `seldon-mesh`. This will install\
the core manager which will handle the key [resources](/seldon-core-2/v2.8/kubernetes/resources.md) used\
by Seldon including the SeldonRuntime and Server resources.

```bash
kubectl create namespace seldon-mesh
```

```bash
helm install seldon-core-v2  seldon-charts/seldon-core-v2-setup --namespace seldon-mesh
```

This will install the operator namespaced so it will only control resources in the provided\
namespace. To allow cluster wide usage add the `--set controller.clusterwide=true`, e.g.

```bash
helm install seldon-core-v2  seldon-charts/seldon-core-v2-setup --namespace seldon-mesh --set controller.clusterwide=true
```

Cluster wide operations will require ClusterRoles to be created so when deploying be aware your\
user will require the required permissions. With cluster wide operations you can create `SeldonRuntimes`\
in any namespace.

## Install the default Seldon Core 2 Runtime

```bash
helm install seldon-v2-runtime seldon-charts/seldon-core-v2-runtime --namespace seldon-mesh
```

This will install the core components in your desired namespace.

## Install example servers

To install some MLServer and Triton servers you can either create Server resources yourself or for\
initial testing you can use our example Helm chart seldon-core-v2-servers:

```bash
helm install seldon-v2-servers seldon-charts/seldon-core-v2-servers --namespace seldon-mesh
```

By default this will install 1 MLServer and 1 Triton in the desired namespace. This namespace should\
be the same namespace you installed a Seldon Core Runtime.

## Uninstall

Remove any models, pipelines that are running.

Remove the runtime:

```bash
helm uninstall seldon-core-v2-runtime  --namespace seldon-mesh
```

Remove the core components:

```bash
helm uninstall seldon-core-v2  --namespace seldon-mesh
```

Remove the CRDs

```bash
helm uninstall seldon-core-v2-crds
```
