Rootsystem is the entrypoint & most highly privileged part of the automation system, hence "root" in the name.

Rootsystem starts the first time a system boots, and it uses provided credentials and options to create, plan & apply multiple terraform projects based on its own collection of terraform modules & ansible roles. It is responsible for installing and configuring the required base-system components of a datacenter, such as:

  • threshold, the public-internet-facing gateway & TCP reverse tunnel
  • serviceroad, the peer-to-peer vpn
  • spigot, the consensus & leader-election service
  • caddy, the Let's Encrypt ACME client, TLS terminator & reverse-proxy

Rootsystem will create one terraform-global project first, where it configures DNS entries and an optional cloud instance to act as an ingress gateway.

Then, it will create a terraform-local-<node-name> project on each node, which will set up node-specific elements of the system, both in the cloud (node-specific DNS entries, threshold configurations, etc) and locally on the node itself.

In the future, rootsystem will also have a continuous-integration-ish role, where it handles configuration changes as they are posted & re-runs builds as needed.

Rootsystem has no user-interface of its own, however, it is tightly coupled to the seedpacket desktop application. Rootsystem posts status updates to object storage, which seedpacket can read & display to the user in real time via polling.
