netbox-rack-design 0.13.2

NetBox plugin for Rack Design.

NetBox Rack Design

Plan rack changes as versioned designs — on top of your real NetBox data, without touching it until you're ready.

NetBox Rack Design adds a lightweight design layer to NetBox for planning device adds, moves, and removals in your racks. A Design is a named, versioned proposal that overlays your live DCIM data: your real dcim.Device and dcim.Rack records stay untouched, and each planned change — add, move, or remove — is captured as a structured placement instead of a spreadsheet cell. This brings the intended rack layout into NetBox and renders it as a projected rack elevation, with power projection and an auto-naming engine already built in — an explicit Apply step and conflict detection are still arriving in later stages.

The plugin is fully generic and public — nothing organization-specific is hardcoded. Status names and behavior are driven entirely by PLUGINS_CONFIG, and only native NetBox mechanisms are used (change logging, tags, custom fields, permissions, REST + GraphQL APIs, global search).

Features

Rack Design pairs a structured data model with an interactive visual editor for composing rack plans. The apply/conflict features are planned (see Roadmap).

• Three models for capturing rack plans:
  • Design — a proposed set of rack changes for a site, scoped to one or more racks. Versioned (clone-and-tweak, with one approved version per plan), ordered for execution per site via an auto-assigned sequence, may declare explicit depends_on relationships, and may optionally belong to a group. Carries title, status, summary, generic external link, plus description/comments/tags/custom fields.
  • DesignGroup — an optional, hierarchical container that links related designs into a larger effort (multi-stage work or cross-site coordination). Purely organizational; never affects execution order.
  • DesignPlacement — a single proposed change within a design: add a new device from the device-type catalog (with an intended role and tenant), move an existing device, or remove (planned) one. Target slots are validated against NetBox's own Rack.get_available_units() collision logic. Real devices are never mutated.
• Interactive multi-rack visual editor — a GridStack drag-and-drop editor that renders all of a design's racks side by side, across both front and rear faces, for composing adds/moves/removes. Includes a searchable device-type catalog palette, per-user favorite device types for quick access, and per-user rack visibility to focus the workspace. Every edit writes placements only — live devices are never touched.
• Projected rack elevations — a read-only elevation view showing how a design's racks would look once applied (all racks, both faces, full-depth devices rendered across both faces), plus a filterable elevations list.
• Rack-page integration — an optional panel on the core dcim.rack detail page listing the designs that touch that rack, each linking to its editor and elevation.
• Config-driven statuses — which device statuses count as "planned" and which mark a planned removal are read from PLUGINS_CONFIG, never hardcoded.
• Naming convention engine — auto-names planned devices via naming_mode = sequence / template / script (a dotted-path callable), with graceful fallback when a template or script fails. See docs/device-naming.md.
• Power projection & PDU distribution — a read-only power overlay: a per-rack capacity-vs-projected-consumption bar plus a per-device power heatmap, and per-PDU/per-bank power distribution (distribution_mode = none / builtin / script) with planned-PDU feed binding. See docs/power-projection-spec.md, docs/power-distribution.md, and docs/pdu-distribution-spec.md.
• Full CRUD UI with list/detail/edit/bulk views and a navigation menu.
• REST API at /api/plugins/rack-design/.
• GraphQL API integration.
• Global search integration.
• Change logging, tags, and custom fields on the models.
• Integration with NetBox's native permission system.

No additional Python packages are required beyond NetBox's own dependencies.

Installation

Install from PyPI into the same environment as your NetBox installation:

pip install netbox-rack-design

For NetBox Docker, add netbox-rack-design to your plugin_requirements.txt. See the netbox-docker plugin instructions.

Enable the plugin in your NetBox configuration (configuration.py, or plugins.py for netbox-docker):

PLUGINS = [
    "netbox_rack_design",
]

# Optional — defaults shown. Only include keys you want to override.
PLUGINS_CONFIG = {
    "netbox_rack_design": {
        "planned_statuses": ["planned"],
        "removal_statuses": ["decommissioning"],
        "default_status": "draft",
        "enable_rack_panel": True,
    },
}

Note on removal_statuses. The default decommissioning is the only native removal-oriented device status on a vanilla install. If decommissioning is destructive in your environment (e.g. it auto-deletes devices or triggers an external dismantle workflow), do not use it for planned removals. Instead add a safe custom status via NetBox's FIELD_CHOICES (for dcim.Device.status, e.g. to_decommission) and point removal_statuses at it.

Apply migrations and restart NetBox:

python manage.py migrate
# then restart your NetBox services (e.g. systemctl restart netbox netbox-rq)

Configuration

All settings are optional and configured under the netbox_rack_design key in PLUGINS_CONFIG.

Key	Default	Description
planned_statuses	["planned"]	Device statuses the plugin treats as "planned".
removal_statuses	["decommissioning"]	Device statuses that mark a planned removal. Override with a safe custom status where decommissioning is destructive (see note above).
default_status	"draft"	Default lifecycle status for a new Design.
enable_rack_panel	True	Show the rack-page panel listing designs that touch a rack.
naming_mode	"sequence"	How a placement's proposed name is computed: "sequence" (<design title>-<n>), "template" (a str.format template over real model objects), or "script" (a dotted path to fn(placement) -> str). See docs/device-naming.md.
naming_template	"{design.name}-{n}"	Template used when naming_mode == "template". Dotted attribute paths on the real Design/Device objects; {design.name} aliases the design title.
naming_script	""	Dotted path to a callable used when naming_mode == "script".
distribution_mode	"none"	How per-PDU/bank load is distributed for the power heatmap: "none" (per-rack total only, per-device gradient), "builtin" (native distribution from bank = outlet port name segment + feed-leg = bound feed, zero config), or "script" (a dotted path to fn(rack, devices) -> Distribution dict). See docs/pdu-distribution-spec.md.
distribution_script	""	Dotted path to a callable used when distribution_mode == "script".
planning_fields	{}	Custom-field bridge mapping site custom fields into the rack/PDU planning dialogs. Empty by default; native fields (voltage/amperage/phase/supply, feed binding) are never listed here.
power_capacity_default_w	1000	Fallback rack power capacity (watts) used when no dcim.PowerFeed is modeled on the rack. Not present in default_settings; read via get_plugin_config with this default.
power_draw_basis	"allocated"	Which PowerPort/PowerPortTemplate field to sum for projected draw: "allocated" or "maximum" (falls back to the other when the chosen one is unset). Not present in default_settings; read via get_plugin_config with this default.
power_warn_pct	80	Utilization percentage at/above which a rack's power state is "warn". Not present in default_settings; read via get_plugin_config with this default.
power_critical_pct	100	Utilization percentage at/above which a rack's power state is "critical". Not present in default_settings; read via get_plugin_config with this default.
power_exclude_roles	("pdu", "unmanageable-pdu")	Device role slugs (case-insensitive) excluded from the power-consumption sum — power infrastructure, not consumers. Not present in default_settings; read via get_plugin_config with this default.

The power_* keys are not listed in the plugin's default_settings (they have no admin-facing default in __init__.py); they are still fully overridable via PLUGINS_CONFIG, resolved at read time by netbox_rack_design/projection.py with the defaults shown above.

Roadmap

Delivered

• Projected rack elevations (read-only) — see how a design's racks would look once applied, with front/rear faces and full-depth devices rendered across both faces.
• Interactive visual rack editor — GridStack drag-and-drop adds/moves/removes across a multi-rack workspace and both rack faces, writing placements without mutating live devices. Includes a searchable device-type catalog palette, per-user favorite device types, and per-user rack visibility.
• Multi-rack designs — a design carries an explicit, site-validated rack scope and a read-only elevation view spanning all of its racks.
• Naming convention engine — auto-names planned devices via naming_mode = "sequence" / "template" / "script", with graceful fallback when a template or script fails.
• Power projection — config-driven capacity vs. projected consumption per rack, rendered as a capacity bar plus a per-device power heatmap.
• PDU power distribution — per-PDU/per-bank load distribution (distribution_mode = "none" / "builtin" / "script"), planned-PDU feed binding for greenfield racks, and a per-bank heatmap.

Planned for upcoming stages

• Apply ("Make in NetBox") — an explicit step that materializes an approved design into real planned devices and applies removal statuses.
• Conflict detection — block approval of designs that conflict with an approved baseline, including dependency conflicts between designs.
• Template-driven export — generate work documents from a design via NetBox's native Export Templates.
