| 1 | +# AuthPolicy Integration with Authzed/SpiceDB |
| 2 | + |
| 3 | +This guide explains how to configure permission requests for a Google Zanzibar-based [Authzed/SpiceDB](https://authzed.com) instance using gRPC. |
| 4 | + |
| 5 | +## Requisites |
| 6 | + |
| 7 | +- [Docker](https://docker.io) |
| 8 | + |
| 9 | +## Run the guide ① → ⑥ |
| 10 | + |
| 11 | +### ① Setup |
| 12 | + |
| 13 | +Clone the repo: |
| 14 | + |
| 15 | +```sh |
| 16 | +git clone [email protected]:Kuadrant/kuadrant-operator.git && cd kuadrant-operator |
| 17 | +``` |
| 18 | + |
| 19 | +Run the following command to create a local Kubernetes cluster with [Kind](https://kind.sigs.k8s.io/), install & deploy Kuadrant: |
| 20 | + |
| 21 | +```sh |
| 22 | +make local-setup |
| 23 | +``` |
| 24 | + |
| 25 | +Request an instance of Kuadrant in the `kuadrant-system` namespace: |
| 26 | + |
| 27 | +```sh |
| 28 | +kubectl -n kuadrant-system apply -f - <<EOF |
| 29 | +apiVersion: kuadrant.io/v1beta1 |
| 30 | +kind: Kuadrant |
| 31 | +metadata: |
| 32 | + name: kuadrant |
| 33 | +spec: {} |
| 34 | +EOF |
| 35 | +``` |
| 36 | + |
| 37 | +### ② Deploy the Talker API |
| 38 | + |
| 39 | +```sh |
| 40 | +kubectl apply -f examples/toystore/toystore.yaml |
| 41 | + |
| 42 | +kubectl apply -f - <<EOF |
| 43 | +apiVersion: gateway.networking.k8s.io/v1 |
| 44 | +kind: HTTPRoute |
| 45 | +metadata: |
| 46 | + name: toystore |
| 47 | +spec: |
| 48 | + parentRefs: |
| 49 | + - name: kuadrant-ingressgateway |
| 50 | + namespace: gateway-system |
| 51 | + hostnames: |
| 52 | + - api.toystore.com |
| 53 | + rules: |
| 54 | + - matches: |
| 55 | + - method: GET |
| 56 | + path: |
| 57 | + type: PathPrefix |
| 58 | + value: "/posts" |
| 59 | + - method: POST |
| 60 | + path: |
| 61 | + type: PathPrefix |
| 62 | + value: "/posts" |
| 63 | + backendRefs: |
| 64 | + - name: toystore |
| 65 | + port: 80 |
| 66 | +EOF |
| 67 | +``` |
| 68 | + |
| 69 | +Export the gateway hostname and port: |
| 70 | + |
| 71 | +```sh |
| 72 | +export INGRESS_HOST=$(kubectl get gtw kuadrant-ingressgateway -n gateway-system -o jsonpath='{.status.addresses[0].value}') |
| 73 | +export INGRESS_PORT=$(kubectl get gtw kuadrant-ingressgateway -n gateway-system -o jsonpath='{.spec.listeners[?(@.name=="http")].port}') |
| 74 | +export GATEWAY_URL=$INGRESS_HOST:$INGRESS_PORT |
| 75 | +``` |
| 76 | + |
| 77 | +Test requests to the unprotected application: |
| 78 | + |
| 79 | +```sh |
| 80 | +curl -H 'Host: api.toystore.com' http://$GATEWAY_URL/posts -i |
| 81 | +# HTTP/1.1 200 OK |
| 82 | +``` |
| 83 | + |
| 84 | +### ③ Create the permission database |
| 85 | + |
| 86 | +Create the namespace for SpiceDB: |
| 87 | + |
| 88 | +```sh |
| 89 | +kubectl create namespace spicedb |
| 90 | +``` |
| 91 | + |
| 92 | +Deploy the SpiceDB instance: |
| 93 | + |
| 94 | +```sh |
| 95 | +kubectl -n spicedb apply -f -<<EOF |
| 96 | +apiVersion: apps/v1 |
| 97 | +kind: Deployment |
| 98 | +metadata: |
| 99 | + name: spicedb |
| 100 | + labels: |
| 101 | + app: spicedb |
| 102 | +spec: |
| 103 | + selector: |
| 104 | + matchLabels: |
| 105 | + app: spicedb |
| 106 | + template: |
| 107 | + metadata: |
| 108 | + labels: |
| 109 | + app: spicedb |
| 110 | + spec: |
| 111 | + containers: |
| 112 | + - name: spicedb |
| 113 | + image: authzed/spicedb |
| 114 | + args: |
| 115 | + - serve |
| 116 | + - "--grpc-preshared-key" |
| 117 | + - secret |
| 118 | + - "--http-enabled" |
| 119 | + ports: |
| 120 | + - containerPort: 50051 |
| 121 | + - containerPort: 8443 |
| 122 | + replicas: 1 |
| 123 | +--- |
| 124 | +apiVersion: v1 |
| 125 | +kind: Service |
| 126 | +metadata: |
| 127 | + name: spicedb |
| 128 | +spec: |
| 129 | + selector: |
| 130 | + app: spicedb |
| 131 | + ports: |
| 132 | + - name: grpc |
| 133 | + port: 50051 |
| 134 | + protocol: TCP |
| 135 | + - name: http |
| 136 | + port: 8443 |
| 137 | + protocol: TCP |
| 138 | +EOF |
| 139 | +``` |
| 140 | + |
| 141 | +Forward local request to the SpiceDB service inside the cluster: |
| 142 | + |
| 143 | +```sh |
| 144 | +kubectl -n spicedb port-forward service/spicedb 8443:8443 2>&1 >/dev/null & |
| 145 | +``` |
| 146 | + |
| 147 | +Create the permission schema: |
| 148 | + |
| 149 | +```sh |
| 150 | +curl -X POST http://localhost:8443/v1/schema/write \ |
| 151 | + -H 'Authorization: Bearer secret' \ |
| 152 | + -H 'Content-Type: application/json' \ |
| 153 | + -d @- << EOF |
| 154 | +{ |
| 155 | + "schema": "definition blog/user {}\ndefinition blog/post {\n\trelation reader: blog/user\n\trelation writer: blog/user\n\n\tpermission read = reader + writer\n\tpermission write = writer\n}" |
| 156 | +} |
| 157 | +EOF |
| 158 | +``` |
| 159 | + |
| 160 | +Create the relationships: |
| 161 | + |
| 162 | +- `blog/user:emilia` → `writer` of `blog/post:1` |
| 163 | +- `blog/user:beatrice` → `reader` of `blog/post:1` |
| 164 | + |
| 165 | +```sh |
| 166 | +curl -X POST http://localhost:8443/v1/relationships/write \ |
| 167 | + -H 'Authorization: Bearer secret' \ |
| 168 | + -H 'Content-Type: application/json' \ |
| 169 | + -d @- << EOF |
| 170 | +{ |
| 171 | + "updates": [ |
| 172 | + { |
| 173 | + "operation": "OPERATION_CREATE", |
| 174 | + "relationship": { |
| 175 | + "resource": { |
| 176 | + "objectType": "blog/post", |
| 177 | + "objectId": "1" |
| 178 | + }, |
| 179 | + "relation": "writer", |
| 180 | + "subject": { |
| 181 | + "object": { |
| 182 | + "objectType": "blog/user", |
| 183 | + "objectId": "emilia" |
| 184 | + } |
| 185 | + } |
| 186 | + } |
| 187 | + }, |
| 188 | + { |
| 189 | + "operation": "OPERATION_CREATE", |
| 190 | + "relationship": { |
| 191 | + "resource": { |

| 200 | + } |
| 201 | + } |
| 202 | + } |
| 203 | + } |
| 204 | + ] |
| 205 | +} |
| 206 | +EOF |
| 207 | +``` |
| 208 | + |
| 209 | +### ④ Create an `AuthPolicy` |
| 210 | + |
| 211 | +Store the shared token for Authorino authentication with the SpiceDB instance: |
| 212 | + |
| 213 | +```sh |
| 214 | +kubectl -n kuadrant-system apply -f -<<EOF |
| 215 | +apiVersion: v1 |
| 216 | +kind: Secret |
| 217 | +metadata: |
| 218 | + name: spicedb |
| 219 | + labels: |
| 220 | + app: spicedb |
| 221 | +stringData: |
| 222 | + grpc-preshared-key: secret |
| 223 | +EOF |
| 224 | +``` |
| 225 | + |
| 226 | +Create `AuthPolicy` custom resource declaring the auth rules to be enforced: |
| 227 | + |
| 228 | +```sh |
| 229 | +kubectl apply -f - <<EOF |
| 230 | +apiVersion: kuadrant.io/v1 |
| 231 | +kind: AuthPolicy |
| 232 | +metadata: |
| 233 | + name: route-auth |
| 234 | +spec: |
| 235 | + targetRef: |
| 236 | + group: gateway.networking.k8s.io |
| 237 | + kind: HTTPRoute |

| 239 | + defaults: |
| 240 | + strategy: atomic |
| 241 | + rules: |
| 242 | + authentication: |
| 243 | + "blog-users": |
| 244 | + apiKey: |
| 245 | + selector: |
| 246 | + matchLabels: |
| 247 | + app: talker-api |
| 248 | + credentials: |
| 249 | + authorizationHeader: |
| 250 | + prefix: APIKEY |
| 251 | + authorization: |
| 252 | + "authzed-spicedb": |
| 253 | + spicedb: |
| 254 | + endpoint: spicedb.spicedb.svc.cluster.local:50051 |
| 255 | + insecure: true |
| 256 | + sharedSecretRef: |
| 257 | + name: spicedb |
| 258 | + key: grpc-preshared-key |
| 259 | + subject: |
| 260 | + kind: |
| 261 | + value: blog/user |
| 262 | + name: |
| 263 | + selector: auth.identity.metadata.annotations.username |
| 264 | + resource: |

| 269 | + permission: |
| 270 | + selector: context.request.http.method.@replace:{"old":"GET","new":"read"}.@replace:{"old":"POST","new":"write"} |
| 271 | +EOF |
| 272 | +``` |
| 273 | + |
| 274 | +### ⑤ Create the API keys |
| 275 | + |
| 276 | +For Emilia (writer): |
| 277 | + |
| 278 | +```sh |
| 279 | +kubectl -n kuadrant-system apply -f -<<EOF |
| 280 | +apiVersion: v1 |
| 281 | +kind: Secret |
| 282 | +metadata: |
| 283 | + name: api-key-writer |
| 284 | + labels: |
| 285 | + authorino.kuadrant.io/managed-by: authorino |
| 286 | + app: talker-api |
| 287 | + annotations: |
| 288 | + username: emilia |
| 289 | +stringData: |
| 290 | + api_key: IAMEMILIA |
| 291 | +EOF |
| 292 | +``` |
| 293 | + |
| 294 | +For Beatrice (reader): |
| 295 | + |
| 296 | +```sh |
| 297 | +kubectl -n kuadrant-system apply -f -<<EOF |
| 298 | +apiVersion: v1 |
| 299 | +kind: Secret |
| 300 | +metadata: |
| 301 | + name: api-key-reader |
| 302 | + labels: |
| 303 | + authorino.kuadrant.io/managed-by: authorino |
| 304 | + app: talker-api |
| 305 | + annotations: |
| 306 | + username: beatrice |
| 307 | +stringData: |
| 308 | + api_key: IAMBEATRICE |
| 309 | +EOF |
| 310 | +``` |
| 311 | + |
| 312 | +### ⑥ Consume the API |
| 313 | + |
| 314 | +As Emilia, send a GET request: |
| 315 | + |
| 316 | +```sh |
| 317 | +curl -H 'Host: api.toystore.com' -H 'Authorization: APIKEY IAMEMILIA' \ |
| 318 | + -X GET \ |
| 319 | + http://$GATEWAY_URL/posts/1 -i |
| 320 | +# HTTP/1.1 200 OK |
| 321 | +``` |
| 322 | + |
| 323 | +As Emilia, send a POST request: |
| 324 | + |
| 325 | +```sh |
| 326 | +curl -H 'Host: api.toystore.com' -H 'Authorization: APIKEY IAMEMILIA' \ |
| 327 | + -X POST \ |
| 328 | + http://$GATEWAY_URL/posts/1 -i |
| 329 | +# HTTP/1.1 200 OK |
| 330 | +``` |
| 331 | + |
| 332 | +As Beatrice, send a GET request: |
| 333 | + |
| 334 | +```sh |
| 335 | +curl -H 'Host: api.toystore.com' -H 'Authorization: APIKEY IAMBEATRICE' \ |
| 336 | + -X GET \ |
| 337 | + http://$GATEWAY_URL/posts/1 -i |
| 338 | +# HTTP/1.1 200 OK |
| 339 | +``` |
| 340 | + |
| 341 | +As Beatrice, send a POST request: |
| 342 | + |
| 343 | +```sh |
| 344 | +curl -H 'Host: api.toystore.com' -H 'Authorization: APIKEY IAMBEATRICE' \ |
| 345 | + -X POST \ |
| 346 | + http://$GATEWAY_URL/posts/1 -i |
| 347 | +# HTTP/1.1 403 Forbidden |
| 348 | +# x-ext-auth-reason: PERMISSIONSHIP_NO_PERMISSION;token=GhUKEzE2NzU3MDE3MjAwMDAwMDAwMDA= |
| 349 | +``` |
| 350 | + |
| 351 | +## Cleanup |
| 352 | + |
| 353 | +If you have started a Kubernetes cluster locally with Kind to try this user guide, delete it by running: |
| 354 | + |
| 355 | +```sh |
| 356 | +make local-cleanup |
| 357 | +``` |
| 358 | + |
| 359 | +Otherwise, delete the resources created in each step: |
| 360 | + |
| 361 | +```sh |
| 362 | +kubectl delete -f examples/toystore/toystore.yaml |
| 363 | +kubectl delete httproute toystore |
| 364 | +kubectl delete authpolicy route-auth |
| 365 | +kubectl delete kuadrant kuadrant -n kuadrant-system |
| 366 | +kubectl delete namespace spicedb |
| 367 | +kubectl delete secret api-key-reader -n kuadrant-system |
| 368 | +kubectl delete secret api-key-writer -n kuadrant-system |
| 369 | +kubectl delete secret spicedb -n kuadrant-system |
| 370 | +``` |
