## Summary Closes #20 Adds Infrahub Jinja2 transforms that query device intent from Infrahub via GraphQL and produce structured JSON payloads (YANG-style) suitable for gNMI Set operations on Arista EOS devices. - **3 GraphQL queries** — `vlan_intent`, `interface_intent`, `vxlan_intent` — each parameterized by `$device_name` - **3 Jinja2 templates** — `vlan_yang.j2`, `interface_yang.j2`, `vxlan_yang.j2` — producing JSON arrays/objects from the GraphQL response - **Integration test fixtures** — one directory per transform with `input.json`, `output.json`, and `test.yml`, using leaf1 from the lab topology as sample device - **`.infrahub.yml` updated** with `queries` and `jinja2_transforms` sections ## Files added ``` transforms/ ├── queries/ │ ├── vlan_intent.gql # VLANs via VTEP mappings + SVI interfaces │ ├── interface_intent.gql # All interface types with IPs │ └── vxlan_intent.gql # VTEP config + VLAN/VNI/VRF mappings ├── templates/ │ ├── vlan_yang.j2 # JSON array of VLANs (merged, deduplicated, sorted) │ ├── interface_yang.j2 # JSON array of interfaces with type discriminator │ └── vxlan_yang.j2 # JSON object: vtep + vlan_vni + vrf_vni mappings └── tests/ ├── vlan_yang/{input,output,test}.{json,yml} ├── interface_yang/{input,output,test}.{json,yml} └── vxlan_yang/{input,output,test}.{json,yml} ``` ## Transform usage ```bash # Render locally infrahubctl render vlan_yang_transform device_name=leaf1 infrahubctl render interface_yang_transform device_name=leaf1 infrahubctl render vxlan_yang_transform device_name=leaf1 # Via API GET /api/transform/jinja2/vlan_yang_transform?device_name=leaf1 GET /api/transform/jinja2/interface_yang_transform?device_name=leaf1 GET /api/transform/jinja2/vxlan_yang_transform?device_name=leaf1 ``` ## Test plan - [x] Load branch into Infrahub (`infrahubctl schema load` + `infrahubctl object load`) - [x] Run `infrahubctl render vlan_yang_transform device_name=leaf1` and verify JSON output matches expected VLANs (40, 4090, 4091) - [x] Run `infrahubctl render interface_yang_transform device_name=leaf1` and verify all interface types are present with correct attributes - [x] Run `infrahubctl render vxlan_yang_transform device_name=leaf1` and verify VTEP source address, UDP port, and VLAN-VNI mapping for VLAN 40 / VNI 110040 - [x] Run `infrahubctl render vxlan_yang_transform device_name=leaf3` and verify VRF gold / L3VNI 100001 appears in `vrf_vni_mappings` - ~~[ ] Verify `infrahubctl test` passes for all three test fixtures~~ Reviewed-on: #24

vlan_yang.j2 — Produce a JSON array of VLAN configuration objects.
|
|
|
|
Input: GraphQL response from vlan_intent query.
|
|
The query returns VLANs from two sources:
|
|
1. data.InfraVTEP[].vlan_vni_mappings[].vlan (L2/VXLAN VLANs)
|
|
2. data.InfraInterfaceVlan[].vlan (SVI/routing/MLAG VLANs)
|
|
|
|
We merge both sources, deduplicate by vlan_id, and emit one object per VLAN.
