Summary

Implements Infrahub Jinja2 Transform for VRF/L3VNI configuration, generating structured JSON payloads from Infrahub intent data. Closes #21.

What's included

GraphQL query (transforms/queries/vrf_intent.gql): Queries InfraVRFDeviceAssignment by device name, fetching VRF details, L3VNI, route targets, and device-specific route distinguisher
Jinja2 transform (transforms/templates/vrf_yang.j2): Renders VRF config payloads with defensive null handling (lessons learned from #20)
.infrahub.yml updated with the new query and transform definitions
Tests (transforms/tests/vrf_yang/) using correct Infrahub pytest format (jinja2-transform-smoke + jinja2-transform-unit-render)

Validation

All transforms render correctly:

Device	Expected	Result
`leaf3`	VRF gold, RD `10.0.250.13:1`, L3VNI 100001	✅
`leaf7`	VRF gold, RD `10.0.250.17:1`, L3VNI 100001	✅
`leaf1`	Empty array (no VRF assignment)	✅
`spine1`	Empty array (no VRF assignment)	✅

Usage

# Local debugging
infrahubctl render vrf_yang_transform device_name=leaf3

# API endpoint
GET /api/transform/jinja2/vrf_yang_transform?device_name=leaf3

Closes #21. ## What's included - **GraphQL query** (`transforms/queries/vrf_intent.gql`): Queries `InfraVRFDeviceAssignment` by device name, fetching VRF details, L3VNI, route targets, and device-specific route distinguisher - **Jinja2 transform** (`transforms/templates/vrf_yang.j2`): Renders VRF config payloads with defensive null handling (lessons learned from #20) - **`.infrahub.yml`** updated with the new query and transform definitions - **Tests** (`transforms/tests/vrf_yang/`) using correct Infrahub pytest format (`jinja2-transform-smoke` + `jinja2-transform-unit-render`) ## Validation All transforms render correctly: | Device | Expected | Result | |--------|----------|--------| | `leaf3` | VRF gold, RD `10.0.250.13:1`, L3VNI 100001 | ✅ | | `leaf7` | VRF gold, RD `10.0.250.17:1`, L3VNI 100001 | ✅ | | `leaf1` | Empty array (no VRF assignment) | ✅ | | `spine1` | Empty array (no VRF assignment) | ✅ | ## Usage ```bash # Local debugging infrahubctl render vrf_yang_transform device_name=leaf3 # API endpoint GET /api/transform/jinja2/vrf_yang_transform?device_name=leaf3 ``` ## Related - Depends on: #20 (base transforms infrastructure, already merged) - Reference: Arista EVPN Type-5 / L3VXLAN configuration from lab topology

feat: Add Infrahub Jinja2 transform for VRF/L3VNI configuration (#21 ) 7b40c5fbe1

- Add GraphQL query vrf_intent.gql: queries InfraVRFDeviceAssignment by
  device name, returning device-specific RD, VRF attributes (name,
  description, l3vni), and both device-level and VRF-level import/export
  route targets for fallback logic
- Add Jinja2 template vrf_yang.j2: renders a JSON array of VRF config
  objects with RD fallback (device → VRF-level) and RT merge logic
  (device-level if present, otherwise VRF-level); all optional
  relationships guarded with 'is defined and is not none' checks
- Update .infrahub.yml: register vrf_intent query and vrf_yang_transform
- Add unit test fixtures for leaf3: input.json (mock GraphQL response)
  and output.json (expected rendered JSON array)
