The new vSphere+/vSAN+ cloud service is now generally available for all customers! For those interested, I recently wrote about my first experience using the new vSphere+vSAN+ service with my vSphere Homelab environment, which I will also be updating based on the generally available service.
In addition to the resources above and in the VMC Cloud Console, here is a link to the official vSphere+/vSAN+ documentation including pre-req.
During my initial deployment of the vCenter Cloud Gateway (VCGW) used by the vSphere+/vSAN+ service, I did not run into any issues but upon deploying my second VCGW for a different environment, I ran into some networking issues. After a bit of debugging, I came to learn that the VCGW application and services are composed of various Docker containers and there was a network conflict with the default Docker Bridge Network that the VCGW has been configured by default with.
