+# Nautobot
+
+## Nautobot Django shell
+
+You can access the Nautobot Django shell by connecting to the pod and running the
+`nautobot-server shell` command.
+
+``` bash
+# find one of the nautobot app pods
+kubectl get pod -l app.kubernetes.io/component=nautobot-default
+NAME                                READY   STATUS    RESTARTS   AGE
+nautobot-default-598bddbc79-kbr72   1/1     Running   0          2d4h
+nautobot-default-598bddbc79-lnjj6   1/1     Running   0          2d4h
+```
+
+``` bash
+# use the nautobot-server shell
+kubectl exec -it nautobot-default-598bddbc79-kbr72 -- nautobot-server shell
+```
+
+## Nautobot GraphQL Queries
+
+### Query for all servers in a specific rack
+
+This queries devices with the role `server` located in rack `rack-123`
+and includes the iDRAC/iLO BMC IP address.
+
+``` graphql
+query {
+  devices(role: "server", rack: "rack-123") {
+    id
+    name
+    interfaces(name: ["iDRAC", "iLO"]) {
+      ip_addresses {
+        host
+      }
+    }
+  }
+}
+```
+
+Output example:
+
+``` json title="rack-123-devices-output.json"
+{
+  "data": {
+    "devices": [
+      {
+        "id": "4933fb3d-aa7c-4569-ae25-0af879a11291",
+        "name": "server-1",
+        "interfaces": [
+          {
+            "ip_addresses": [
+              {
+                "host": "10.0.0.1"
+              }
+            ]
+          }
+        ]
+      },
+      {
+        "id": "f6be9302-96b0-47e9-ad63-6056a5e9a8f5",
+        "name": "server-2",
+        "interfaces": [
+          {
+            "ip_addresses": [
+              {
+                "host": "10.0.0.2"
+              }
+            ]
+          }
+        ]
+      }
+    ]
+  }
+}
+```
+
+Some jq to help parse the output:
+
+``` bash
+cat rack-123-devices-output.json | jq -r '.data.devices[] | "\(.id) \(.interfaces[0]["ip_addresses"][0]["host"])"'
+```
+
+Output:
+
+``` text
+4933fb3d-aa7c-4569-ae25-0af879a11291 10.0.0.1
+f6be9302-96b0-47e9-ad63-6056a5e9a8f5 10.0.0.2
+```
