Portworx vSphere installation

Step 1: vCenter user for Portworx

You will need to provide Portworx with a vCenter server user that has the following minimum vSphere privileges:

• Datastore
  • Allocate space
  • Browse datastore
  • Low level file operations
  • Remove file
• Host
  • Local operations
  • Reconfigure virtual machine
• Virtual machine
  • Change Configuration
  • Add existing disk
  • Add new disk
  • Add or remove device
  • Advanced configuration
  • Change Settings
  • Extend virtual disk
  • Modify device settings
  • Remove disk

If you create a custom role as above, make sure to select “Propagate to children” when assigning the user to the role.

Step 2: Create a Kubernetes secret with your vCenter user and password

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

• VSPHERE_USER: Use output of echo '<vcenter-server-user>' | base64

• VSPHERE_PASSWORD: Use output of echo '<vcenter-server-password>' | base64

  apiVersion: v1
  kind: Secret
  metadata:
   name: px-vsphere-secret
   namespace: kube-system
  type: Opaque
  data:
   VSPHERE_USER: XXXX
   VSPHERE_PASSWORD: XXXX

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

Step 3: Generate the specs

vSphere environment details

Export the following environment variables based on your vSphere environment. These variables will be used in a later step when generating the YAML spec.

# Hostname or IP of your vCenter server
export VSPHERE_VCENTER=myvcenter.net

# Prefix of your shared ESXi datastore(s) names. Portworx will use datastores who names match this prefix to create disks.
export VSPHERE_DATASTORE_PREFIX=mydatastore-

# Change this to the port number vSphere services are running on if you have changed the default port 443
export VSPHERE_VCENTER_PORT=443

Disk templates

A disk template defines the VMDK properties that Portworx will use as a reference for creating the actual disks out of which Portworx will create the virtual volumes for your PVCs.

The template adheres to the following format:

type=<vmdk type>,size=<size of the vmdk>

• type: Supported types are thin, zeroedthick, eagerzeroedthick, and lazyzeroedthick
• size: This is the size of the VMDK in GiB

The following example will create a 150GB zeroed thick vmdk on each VM:

export VSPHERE_DISK_TEMPLATE=type=zeroedthick,size=150

Generate the spec file

Now generate the spec with the following curl command.

export VER=$(kubectl version --short | awk -Fv '/Server Version: /{print $3}')
curl -fsL -o px-spec.yaml "https://install.portworx.com/2.13?kbver=$VER&c=portworx-demo-cluster&b=true&st=k8s&csi=true&vsp=true&ds=$VSPHERE_DATASTORE_PREFIX&vc=$VSPHERE_VCENTER&s=%22$VSPHERE_DISK_TEMPLATE%22"

Apply specs

Apply the Operator and StorageCluster specs you generated in the section above using the kubectl apply command:

1. Deploy the Operator:

   kubectl apply -f 'https://install.portworx.com/<version-number>?comp=pxoperator'

   serviceaccount/portworx-operator created
   podsecuritypolicy.policy/px-operator created
   clusterrole.rbac.authorization.k8s.io/portworx-operator created
   clusterrolebinding.rbac.authorization.k8s.io/portworx-operator created
   deployment.apps/portworx-operator created

2. Deploy the StorageCluster:

   kubectl apply -f 'https://install.portworx.com/<version-number>?operator=true&mc=false&kbver=&b=true&kd=type%3Dgp2%2Csize%3D150&s=%22type%3Dgp2%2Csize%3D150%22&c=px-cluster-XXXX-XXXX&eks=true&stork=true&csi=true&mon=true&tel=false&st=k8s&e==AWS_ACCESS_KEY_ID%3XXXX%2CAWS_SECRET_ACCESS_KEY%3XXXX&promop=true'

   storagecluster.core.libopenstorage.org/px-cluster-0d8dad46-f9fd-4945-b4ac-8dfd338e915b created

Monitor the Portworx pods

1. Enter the following kubectl get command, waiting until all Portworx pods show as ready in the output:

   kubectl get pods -o wide -n kube-system -l name=portworx

2. Enter the following kubectl describe command with the ID of one of your Portworx pods to show the current installation status for individual nodes:

    kubectl -n kube-system describe pods <portworx-pod-id>

   NOTE: In your output, the image pulled will differ based on your chosen Portworx license type and version.

Monitor the cluster status

Use the pxctl status command to display the status of your Portworx cluster:

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