Platform9 Managed Bare Metal with Metal³ Architecture

There are several great open-source tools for bare-metal host provisioning, including Ironic. Metal3 is built on these technologies to provide a Kubernetes native API for managing bare metal hosts via a provisioning stack that is also running on Kubernetes essentially Metal³ acts as the Kubernetes wrapper around Ironic.

High-level architecture of the Metal³ on PMK

Services like ironic, PxE, httpd are running in the host as containers attached to the host network on the host’s provisioning interface. In addition, the vbmc service is also running as a privileged container and it is listening in the host’s primary interface.

The following are primary components of Metal³

• Baremetal Operator
• Ironic
• Bare metal host CR
