V2.0.0 - Diagrams

[Timmoth]

RackPeek 2.0.0

What's New

Web UI

• Visualise page (/visualise) — live network diagrams
  rendered from your inventory, with a tab toggle between
  Physical (hardware topology with rack/host groupings and
  port-level connections) and Logical (services & systems
  grouped by subnet and host). One-click Save PNG and Save
  Mermaid (.mmd) for embedding in docs or sharing.
• Diagram previews on the home page — the dashboard now
  embeds compact Physical Topology and Logical View cards
  next to the totals, each with an open → jump to the full
  Visualise tab.
• Better YAML import errors — invalid YAML now surfaces the
  exact line, column, and a contextual snippet pointing at
  the offending line, rather than dumping the raw parser
  stack trace. Same treatment for in-place YAML file edits.

CLI

• rpk graph topology — emits a Mermaid flowchart of the
  physical topology (hardware + connections) on stdout, ready
  to pipe into a .mmd file or any Mermaid renderer.
• rpk graph logical — same, for services & systems grouped
  by subnet.
• Tag commands on every resource kind: rpk tag add
  / rpk tag remove for all
  ten kinds (servers, switches, routers, firewalls, access
  points, UPSs, systems, services, desktops, laptops).
• Tag discovery: rpk tags list (every tag in use, with
  counts) and rpk tags show (every resource carrying
  that tag).

API

• New POST /api/inventory endpoint — upsert resources via
  YAML or JSON over HTTP. Supports mode: merge (preserves
  unspecified fields) and mode: replace (overwrites). dryRun:
  true returns the computed diff (added / updated / replaced
  plus oldYaml / newYaml snapshots) without persisting, so
  you can preview a change before applying it.
• Authenticated via X-Api-Key header. The endpoint returns
  503 if RPK_API_KEY is unset and 401 for a wrong key.
• Tags are wholesale-replaced in merge mode; labels are
  merged key-wise.

Git Sync

• Auto-initialises a Git repo on first run when GIT_TOKEN
  is set and the config directory is a plain folder (no
  .git/). No more "Git is not available" dead-end for
  first-time users — Add Remote works immediately.
