Testing Directord at 408 node scale using 8 virtual machines.

VM Flavor

3 vCPU
5 GiB RAM
40 GiB Disk

Operating System: CentOS 8 Stream

This process installs Directord using the tools scripts, bootstraps the 8 Virtual Machines, and then runs a built-in Directord orchestration to deploy 400 containers.

Once everything is online, a simple “hello world” command is executed against all 408 targets, completing in roughly 2 seconds.
