Install the TimesTen Custom Resource Definitions (CRDs)

The TimesTen Operator provides two Custom Resource Definitions (CRDs) called timestenclassics.timesten.oracle.com and timestenscaleouts.timesten.oracle.com. These CRDs define the TimesTenClassic and TimesTenScaleout object types.

Let's use Helm to install the TimesTen CRDs into your Kubernetes cluster. Since CRDs are cluster-wide, the CRDs are available to all namespaces after they are installed. Let's install the CRDs by installing the TimesTen Operator's ttcrd chart. You cannot customize the ttcrd chart. Therefore, let's install the chart as is.

For more information about using Helm to install a chart, see https://helm.sh/docs/intro/using_helm/.

On your development host, change to the helm directory. For more information about the helm directory, see Set Up the Environment.
```
cd kube_files/helm
```

Install the ttcrd chart.

helm install ttcrd ./ttcrd

Output.
