Scope

Design and implementation summary for the Tailscale networking foundation managed as infrastructure-as-code.

Key Points

  • Tailscale was elevated from ad-hoc VPN usage to declarative infrastructure
  • OAuth clients were preferred over expiring pre-auth keys for long-lived automation
  • ACL policy was maintained as a dedicated acl.json artifact for clarity and validation
  • Tailscale bootstrap credentials were integrated into the TazPod secret model rather than stored insecurely

Notable Claims

  • pre-auth keys were rejected as predictable technical debt for rebirth-oriented infrastructure
  • Terraform support for tailscale_oauth_client changed the implementation quality significantly by making the bootstrap identity declarative and stateful
