Using PowerCLI and vSphere Tags to create/migrate HCX Mobility Groups to VMware Cloud SDDC

by // 3 Comments

If using your voice to create an HCX Mobility Group and initiate a migration to a VMware Cloud SDDC is not your thing, here is a more practical example using PowerCLI which includes HCX cmdlets that was introduced awhile back.


Here are the 12 configurable variables that you will need to update based on your own environment.

$VC_SERVER="vcsa.vmware.corp"
$VC_USERNAME="*protected email*"
$VC_PASSWORD="VMware1!"
$HCX_SERVER="hcx.vmware.corp"

$VSPHERE_TAG_CATEGORY="Cloud"
$VSPHERE_TAG_NAME="VMC"

# vMotion, Bulk, Cold, RAV, OsAssistedMigration
$MIGRATION_TYPE="RAV"

$TARGET_NETWORK_NAME="L2E_HOL-10-f58e483b"
$TARGET_DATASTORE_NAME="WorkloadDatastore"
$TARGET_RESOURCE_POOL_NAME="Compute-ResourcePool"
$TARGET_VM_FOLDER_NAME="Workloads"

$MOBILITY_GROUP_NAME="VMworld-2020-Demo"

Tanzu Kubernetes Grid (TKG) Demo Appliance 1.1.3

by // 1 Comment

It has been awhile since I have updated my Tanzu Kubernetes Grid (TKG) Demo Appliance Fling, which is a virtual appliance that enables anyone to go from zero to Kubernetes in less than 30 minutes with just an SSH client and a web browser. For VMware Cloud on AWS customers interested in running TKG, this is a great way to quickly get started on a proof of concept, demo or for development and testing purposes. One great benefit is that everything required for TKG is self contained within the appliance including an embedded Harbor registry and the respective TKG container images, great for air-gapped or non-internet accessible environments.

Here is a summary of what is new:

Support for latest TKG 1.1.3

There have been several of smaller releases to TKG since their 1.0.0 release but due to their short lifecycle, I decided to hold off. Behind the scenes, I have actually been working closely with TKG team on the latest TKG 1.1.3 release which was just release last week. One really cool feature that was introduced in TKG 1.1.2 is the ability to upgrade an existing TKG Workload Cluster to a newer version of Kubernetes.

With TKG 1.1.3, support for Kubernetes v1.18.6 and v1.17.9 is now possible and the latest version of the demo appliance will also support this workflow. In fact, I have also updated my TKG Workshop Guide to include all new updates including the upgrade workflow. To reduce the maintenance burden on myself, the TKG Demo Appliance 1.0.0 will be removed in the near future, for now it has been deprecated but all existing content is still available. I highly recommend checking out the latest version as you will get all the latest features of TKG.

Using the new installation method for deploying OpenShift 4.5 on VMware Cloud on AWS

by // 1 Comment

I recently saw a tweet from Jason Shiplett who works over on the VMware Validated Design (VVD) team (also my former team before joining VMware Cloud) who shared a new validated design for running Redhat OpenShift 4.3 on VMware Cloud Foundation. Funny enough, a couple of days ago I was just researching into deploying OpenShift running on VMware Cloud on AWS from a customer inquiry.

Timing could not have been better as RedHat just announced their OpenShift 4.5 release a few days ago as and one of the major updates is support for vSphere using their full stack automation also known as te Installer Provisioned Infrastructure (IPI) option. Previous to this, customers who wanted to deploy OpenShift on vSphere had to use the User Provisioned Infrastructure (UPI) method, which the VVD design also uses, which is much lengthier and complex when compared to the native IPI method.

For someone who has never worked with OpenShift before, this was great news and I get to try out this new deployment method on an VMware Cloud on AWS infrastructure 🙂

Pre-Requisites:

Step 1 - You will need a Linux system to perform the installation and it should have access to the vCenter Server running in VMware Cloud on AWS (VMC). In my example, I am using an Ubuntu Server 20.04 VM which is also running in the SDDC and has outbound internet connectivity.

Step 2 - Login to VMware Cloud on AWS console and create a new NSX-T network segment that is DHCP enabled. In my example, I named it openshift-network with a 192.168.3.0/24 configuration.


Step 3 - Navigate to Inventory->Groups and create the following groups and replace the CIDR networks with that of your SDDC:

Group Name IP Address Members
Compute OpenShift Network 192.168.3.0/24
Compute SDDC Management Network 10.2.0.0/16
Management OpenShift Network 192.168.3.0/24
