Automated Bare Metal Provisioning with Tinkerbell

Submitted May 5, 2020

Even though we are seeing the advent of virtual servers, bare metal servers are preferred for use cases where performance and security are critical. The provisioning and lifecycle management of bare metal servers is extremely challenging. Tinkerbell, an open-source project from Packet helps automate infrastructure provisioning of bare metal servers irrespective of who provides them (cloud/on-prem).

In this session, we will see how Tinkerbell makes it easy to provision bare metal servers. We will be talking about how it uses:

  • a YAML based definition to automate provisioning
  • a control plane to manage servers at scale
  • latest technologies like Docker containers, gRPC, iPXE, etc.

Key takeaways are:

  • Overview of bare metal cloud
  • How Tinkerbell works to make provisioning servers at ease
  • Architecture review
  • Primary technologies - iPXE, DHCP, TFTP
  • When and where to use Tinkerbell?
  • Where are we and what’s next?


We will cover basic bare metal concepts, and then jump on a ride with Tinkerbell covering following things:

  • Overview of bare metal cloud
  • Introduction to Tinkerbell
  • Primary Concepts:
    • iPXE
    • DHCP
    • TFTP
  • High-level Architecture
  • First good workflow(demo)
  • Provisioning an Ubuntu server(demo)


No special requirements for the session. Good internet connection during the demo period.
