After checking out the features of the official Docker registry, I was a bit underwhelmed by the missing repo based auth and the lack of combining the use as repository and cache. Read more

Having to log into all of your VKS clusters one by one sucks as you either have to export your vSphere Password as an environment variable (which is kinda insecure) or enter the Password for each of your Clusters over and over again.

When using NSX-T for networking in combination with NSX ALB for load balancing in the vSphere IaaS Control Plane, the ALB Service Engines attach to each Tier-1 Router (vSphere Namespace) with one vNIC. Naturally, there’s a limit of 10 vNICs per Service Engine, meaning we can connect up to 8 Tier-1 routers to one Service Engine, as one vNIC is needed for management and another for frontend traffic. We were curious to see how NSX ALB would handle more than 8 vSphere Namespaces in this setup. My colleague Steven Schramm and I decided to test this in our lab. Read more

While I was testing Broadcom’s new Release 8.0.3, I encountered some issues getting my nested lab to work in a Proxmox environment. Despite enabling Nested Virtualization on all Proxmox nodes and setting the VM CPU type to ‘host,’ the vCLS service wouldn’t start due to EVC issues, causing DRS to malfunction. Troubleshooting Nested Virtualization First, I checked whether nested virtualization was enabled on the Proxmox nodes. This can be verified with the following command: Read more

VMware by Broadcom has recently released the “Consumption Interface” for the vSphere IaaS Control Plane (formerly known as vSphere with Tanzu or TKGS).

With this new interface, you can now view and manage all your resources within vSphere namespaces directly from the vCenter GUI. This update simplifies the creation and updating of resources, enhancing the user experience. Read more
