Introduction
VMware By Broadcom has moved away from the old, clunky Host Profiles in favor of the modern Desired State Cluster Configuration. This “Desired-State” model is fantastic for consistency, but it introduces a new challenge: managing the massive JSON documents that define your cluster’s state.
When you need to scale a cluster, you’re often stuck manually editing host-specific overrides for IPs and hostnames inside a complex JSON structure. I built ClusterConfigForge to turn that manual grind into a streamlined, automated workflow.
The Challenge: Scaling Desired-State Configurations
In the Desired-State model, the entire configuration for a cluster is managed as a single document. While this is great for avoiding “configuration drift,” updating unique host details (like Management/vMotion IPs) for a 32-node cluster still requires tedious, repetitive data entry.
If you’re a consultant or a lead admin, you don’t want to spend your afternoon copy-pasting IPv4 addresses into a text editor. You want a tool that understands the structure and does the heavy lifting for you.
