examples

1) Build a 3 node culster on an already connected vcenter (connect-viserver vcenter) from a template vm ubuntu-18.0.4-lts with a user k8admin already created on the network "VM Network"
```
.\k8-lc.ps1 -username k8admin -nodes 3 -clusterName Test-Cluster -clonefrom ubuntu-18.0.4-lts -portGroup "VM Network" -nsxNetwork "Pod Network" -nsxUsername admin -nsxSecurePassword VMware1!
```
2) Scale existing cluster Test-Cluster up by 3 nodes
```
.\k8-lc.ps1 -username k8admin -nodes 2 -clusterName Test-Cluster -clonefrom ubuntu-18.0.4-lts -portGroup "VM Network" -nsxNetwork "Pod Network" -nsxUsername admin -nsxSecurePassword VMware1!
```
3) Scale existing cluster Test-Cluster down by 2 nodes
```
.\k8-lc.ps1 -username k8admin -nodes 2 -clusterName Test-Cluster -clonefrom ubuntu-18.0.4-lts -portGroup "VM Network" -remove $true -nsxNetwork "Pod Network" -nsxUsername admin -nsxSecurePassword VMware1!
```
4) Delete cluster Test-Cluster
```
.\k8-lc.ps1 -username k8admin -nodes 3 -clusterName Test-Cluster -clonefrom ubuntu-18.0.4-lts -portGroup "VM Network" -remove $true -master $true -nsxNetwork "Pod Network" -nsxUsername admin -nsxSecurePassword VMware1!
