Minikube can be used for testing and evaluating Optimizer Hub.

You should run Optimizer Hub on minikube only for evaluation purposes. Make sure your minikube meets the 18 vCore minimum for running Optimizer Hub. Although minikube can run on multiple platforms, Optimizer Hub is only available for the x64 platform, so not on macOS with M1/2.

Installing Minikube

Install minikube for your platform following this installation guide.

Installing Optimizer Hub

Optimizer Hub uses Helm as the deployment manifest package manager. There is no need to manually edit any Kubernetes deployment manifests.

Make sure your Helm version is v3.8.0 or newer.

Add the Azul Helm repository to your Helm environment:

 helm repo add opthub-helm https://azulsystems.github.io/opthub-helm-charts/
helm repo update

Create a namespace (i.e. my-opthub) for Optimizer Hub.
```
 minikube kubectl -- create namespace my-opthub
```
Create a configuration file values-minikube.yaml.

An example file is available on GitHub in the Azul "opthub-helm-charts" project, to disable all resource definitions.

As the supplied values file for minikube resets pod resources to null, we can simply add only the persistent volume section:
```
 db:
  resources:
  persistentDataVolume:
    enabled: true
```
You can also set the volume size if the default 200Gi is too big for local testing:
```
 db:
  resources:
  persistentDataVolume:
    enabled: true
    size: "50Gi"
```
Install using Helm, passing in the values-minikube.yaml. In case you don’t want to install the full Optimizer Hub, but only a part of the services, first check "Configuring the Active Optimizer Hub Services".
```
 helm install opthub opthub-helm/azul-opthub -n my-opthub -f values-minikube.yaml
```
The command should produce output similar to this:
```
 NAME: opthub
LAST DEPLOYED: Mon Jan 30 14:35:29 2023
NAMESPACE: my-opthub
STATUS: deployed
REVISION: 1
TEST SUITE: None
```

Verify that all started pods are ready:

 minikube kubectl -- get all -n my-opthub

Uninstalling Optimizer Hub from Minikube

Optimizer Hub can be removed from minikube using helm, after which the namespace can also be deleted.

 helm uninstall opthub -n my-opthub
minikube kubectl -- delete namespace my-opthub
