Setting up Portworx on a Tanzu Kubernetes Grid aka TKG Cluster

First, this process works today on clusters made with the TKG tool that does not use the embedded management cluster. For clarity I call those clusters TKC or TKC Guest Clusters. The run as VM’s. You just can’t add block devices outside of the Cloud Native Storage (VMware’s CSI Driver). At least I couldn’t.

Now TKG deploys using a Photon 3.0 template. When I wrote this blog and recorded the demo the current latest version is TKG 1.2.1 and the k8s template is 1.19.3-vmware.

Check the release notes here:

First generate base64 encoded versions of your user and password to vCenter.

# Update the following items in the Secret template below to match your environment:

VSPHERE_USER: Use output of printf <vcenter-server-user> | base64
VSPHERE_PASSWORD: Use output of printf <vcenter-server-password> | base64

The vsphere-secret.yaml save this to a file with your own user and password to vCenter (from above).

apiVersion: v1
kind: Secret
  name: px-vsphere-secret
  namespace: kube-system
type: Opaque

kubectl apply the above spec after you update the above template with your user and password.

Follow these steps:

# create a new TKG cluster
tkg create cluster tkg-portworx-cluster -p dev -w 3 --vsphere-controlplane-endpoint-ip 10.21.x.x 

# Get the credentials for your config
tkg get credentials tkg-portworx-cluster

# Apply the secret and the operator for Portworx
kubectl apply -f vsphere-secret.yaml
kubectl apply -f ''

#generate your spec first, you get this from generating a spec at
kubectl apply -f tkg-px.yaml 

# Wait till it all comes up.
watch kubectl get pod -n kube-system

# Check pxctl status
PX_POD=$(kubectl get pods -l name=portworx -n kube-system -o jsonpath='{.items[0]}')
kubectl exec $PX_POD -n kube-system -- /opt/pwx/bin/pxctl status

You can now create your own or use the premade storageClass

kubectl get sc
default (default)                Delete          Immediate           false                  7h50m
px-db                     Delete          Immediate           false                  7h44m
px-db-cloud-snapshot      Delete          Immediate           false                  7h44m
px-db-cloud-snapshot-encrypted   Delete          Immediate           false                  7h44m
px-db-encrypted           Delete          Immediate           false                  7h44m
px-db-local-snapshot      Delete          Immediate           false                  7h44m
px-db-local-snapshot-encrypted   Delete          Immediate           false                  7h44m
px-replicated             Delete          Immediate           false                  7h44m
px-replicated-encrypted   Delete          Immediate           false                  7h44m
stork-snapshot-sc                stork-snapshot                  Delete          Immediate           false                  7h44m

Now Deploy Kube-Quake

The example.yaml is from my fork of the kube-quake repo on github where I redirected the data to be on a persistent volume.

kubectl apply -f
deployment.apps/quakejs created
service/quakejs created
configmap/quake3-server-config created
persistentvolumeclaim/quake3-content created

k get pod
NAME                      READY   STATUS              RESTARTS   AGE

k get pvc

k get svc

quakejs      LoadBalancer   <pending>     8080:32527/TCP,27960:31138/TCP,9090:30313/TCP   2m47s

Now point your browser to: http://<some node ip>:32527
Or if you have the LoadBalancer up and running go to the http://<Loadbalancer IP>:8080
