HTTP method

Specify an HTTP method, such as POST, GET, PUT, PATCH, or DELETE, to match requests against.

For more information, see the Kubernetes Gateway API documentation.

Before you begin

  1. Set up an agentgateway proxy.
  2. Install the httpbin sample app.

Set up HTTP method matching

  1. Create an HTTPRoute resource for the match.example domain that serves incoming GET requests for the httpbin app.

    kubectl apply -f- <<EOF
apiVersion: gateway.networking.k8s.io/v1
kind: HTTPRoute
metadata:
  name: httpbin-match
  namespace: httpbin
spec:
  parentRefs:
    - name: agentgateway-proxy
      namespace: agentgateway-system
  hostnames:
    - match.example
  rules:
    - matches:
      - method: "GET"
      backendRefs:
        - name: httpbin
          port: 8000
EOF

  2. Send a GET request to the httpbin app on the match.example domain. Verify that you get back a 200 HTTP response code. 

    curl -vi http://$INGRESS_GW_ADDRESS:80/get -H "host: match.example"
    curl -vi localhost:8080/get -H "host: match.example"

    Example output:

    HTTP/1.1 200 OK
< access-control-allow-credentials: true
access-control-allow-credentials: true
< access-control-allow-origin: *
access-control-allow-origin: *
< content-type: application/json; encoding=utf-8
content-type: application/json; encoding=utf-8
< content-length: 322
content-length: 322
< 

{
  "args": {},
  "headers": {
    "Accept": [
      "*/*"
   ],
    "Host": [
      "match.example"
    ],
    "Traceparent": [
      "00-30f560cded924883c1eebfecfd8a8367-3eedcde5b0a6924f-01"
    ],
    "User-Agent": [
      "curl/8.7.1"
    ]
  },
  "origin": "10.xxx.x.xx:55304",
  "url": "http://match.example/get"
}

  3. Send another request to the httpbin app on the match.example domain. This time, you use the POST method. Verify that your request is not forwarded to the httpbin app and that you get back a 404 HTTP response code. 

    curl -vi -X POST http://$INGRESS_GW_ADDRESS:80/post -H "host: match.example" 
    curl -vi -X POST localhost:8080/post -H "host: match.example"

    Example output:

    < HTTP/1.1 404 Not Found
HTTP/1.1 404 Not Found
< content-length: 9
content-length: 9
< content-type: text/plain; charset=utf-8
content-type: text/plain; charset=utf-8

Cleanup

You can remove the resources that you created in this guide. 
kubectl delete httproute httpbin-match -n httpbin
