# org.etsi.osl.controllers.sylva

A  kubernetes operator to manage Sylva Workload clusters


## Getting started


To install the operator you need as input a kubeconfig to the OSL management cluster and a kubeconfig of the Sylva management cluster

```
helm install oslsylva . --set-file  kubeconfig=../src/main/resources/config --set-file sylvamgtconfig=../src/main/resources/management-cluster-kubeconfig
```

Then you need to:

Install kustomization.sylvamd.configmaps.osl.etsi.org in default namespace

Install secrets.sylvamd.configmaps.osl.etsi.org in default namespace

examples of such files are available in src/main/resources folder.

Example usage of the operator:

the kind installed is of  SylvaMDResource under group: controllers.osl.etsi.org 


It accepts either simple a number of clusterControlPlaneReplicas and clusterMd0Replicas or a full values yaml file.


Examples:

request a sylva workload cluster with 1 master 3 worker nodes

```
apiVersion: controllers.osl.etsi.org/v1alpha1
kind: SylvaMDResource
metadata:
  name: wc12345-aaeeff
spec:
  clusterControlPlaneReplicas: "1"
  clusterMd0Replicas: "3"
```



request a sylva workload cluster with 1 master 3 worker nodes, but with a values.yaml spec


```
apiVersion: controllers.osl.etsi.org/v1alpha1
kind: SylvaMDResource
metadata:
  name: wc67890-bbccdd

The status returns the state of the process as well as a kubeconf to connect to the remote WC, in the secret field as BASE64 encoded string.
