Deploy Changes in Configuration Options

You can always introduce or update your vcluster.yaml and deploy new configuration options.

The vCluster control plane pod will be re-deployed.

Remember that you can't change distros or backing store once a vCluster is deployed.

vCluster CLI Version

To keep the same version of your vCluster, your CLI needs to be the same version as your virtual cluster.

vcluster create --upgrade <VCLUSTER_NAME> -n <VCLUSTER_NAMESPACE> -f vcluster.yaml

Replace:

<VCLUSTER_NAME> with the name of the vCluster instance to update.
<VCLUSTER_NAMESPACE> with the namespace where the vCluster instance is deployed.

helm upgrade --install <VCLUSTER_NAME> vcluster \
  --values vcluster.yaml \
  --repo https://charts.loft.sh \
  --namespace <VCLUSTER_NAMESPACE> \
  --repository-config=''

Replace:

<VCLUSTER_NAME> with the name of the vCluster instance to update.
<VCLUSTER_NAMESPACE> with the namespace where the vCluster instance is deployed.

The steps assume that you have the terraform file that you initially deployed your terraform resource from.

Generate a new plan with your updated vcluster.yaml.
```
terraform plan
```
Verify that the provider can access your cluster and that the proposed changes are correct.
Apply your new changes.
```
terraform apply
```

Commit and push your updated vcluster.yaml to your configured ArgoCD repository.
Synchronize your ArgoCD repository with your configured cluster.

Learn more about Cluster API Provider for vCluster.

Install the vCluster provider.

clusterctl init --infrastructure vcluster:v0.2.0

Export environment variables to be used by the cluster API provider to create an updated manifest. The manifest will be applied to your Kubernetes cluster, which will update your vCluster with the updated configuration options.
```
 # Replace <VCLUSTER_NAME> and <VCLUSTER_NAMESPACE> with values of the vCluster that you are updating
 export CLUSTER_NAME=<VCLUSTER_NAME>
 export CLUSTER_NAMESPACE=<VCLUSTER_NAMESPACE>
 
 # Since the vcluster.yaml has changed, you'll need to re-export it to the updated vcluster.yaml
 export VCLUSTER_YAML=$(awk '{printf "%s\\n", $0}' vcluster.yaml)
```
Replace:
- <VCLUSTER_NAME> with the name of the vCluster instance to update.
- <VCLUSTER_NAMESPACE> with the namespace where the vCluster instance is deployed.
Regenerate the manifest and apply the updated manifest.
```
 clusterctl generate cluster ${CLUSTER_NAME} \
   --infrastructure vcluster \
   --target-namespace ${CLUSTER_NAMESPACE} \
    | kubectl apply -f -
```
Kubernetes Version
The Kubernetes version for the vCluster is not set at the CAPI provider command. It is configured the vcluster.yaml file based on your Kubernetes distribution.

Wait for vCluster to be updated by watching for the vCluster custom resource to report a ready status.

kubectl wait --for=condition=ready vcluster -n $CLUSTER_NAMESPACE $CLUSTER_NAME --timeout=300s
