如何部署httpbin应用 - Alibaba Cloud Service Mesh - Alibaba Cloud Documentation Center

HTTPBin is an open source application for testing and is commonly used for web debugging. After you deploy the HTTPBin application, you can easily view the methods, headers, and authorization information of HTTP requests. This topic describes how to deploy the HTTPBin application.

Prerequisites

Procedure

Deploy the HTTPBin application in the Container Service for Kubernetes (ACK) cluster on the data plane.

Use the following content to create an httpbin-application.yaml file:

Expand to view the httpbin-application.yaml file

apiVersion: v1
kind: ServiceAccount
metadata:
  name: httpbin
---
apiVersion: v1
kind: Service
metadata:
  name: httpbin
  labels:
    app: httpbin
    service: httpbin
spec:
  ports:
  - name: http
    port: 8000
    targetPort: 80
  selector:
    app: httpbin
---
apiVersion: apps/v1
kind: Deployment
metadata:
  name: httpbin
spec:
  replicas: 1
  selector:
    matchLabels:
      app: httpbin
      version: v1
  template:
    metadata:
      labels:
        app: httpbin
        version: v1
    spec:
      serviceAccountName: httpbin
      containers:
      - image: docker.io/kennethreitz/httpbin
        imagePullPolicy: IfNotPresent
        name: httpbin
        ports:
        - containerPort: 80

Use kubectl to connect to the ACK cluster and run the following command to deploy the HTTPBin application:
```
kubectl apply -f httpbin-application.yaml
```

Configure a traffic rule for the HTTPBin application.

Use the following content to create an Istio gateway. For more information, see Manage Istio gateways.

apiVersion: networking.istio.io/v1beta1
kind: Gateway
metadata:
  name: httpbin
  namespace: default
spec:
  selector:
    istio: ingressgateway
  servers:
    - hosts:
        - '*'
      port:
        name: test
        number: 80
        protocol: HTTP

Use the following content to create a virtual service. For more information, see Manage virtual services.

apiVersion: networking.istio.io/v1beta1
kind: VirtualService
metadata:
  name: httpbin-vs
  namespace: default
spec:
  gateways:
    - httpbin
  hosts:
    - '*'
  http:
    - name: test
      route:
        - destination:
            host: httpbin.default.svc.cluster.local
            port:
              number: 8000

Perform access tests.
Replace the IP address of the ASM gateway in the following commands with the actual IP address of the ASM gateway. For more information about how to obtain the IP address of an ASM gateway, see Obtain the IP address of the ingress gateway.
1. Run the following command to access the /status/200 path of the HTTPBin application:
```
curl http://${IP address of the ASM gateway}/status/200 -v
```
  200 OK is returned.
2. Run the following command to access the /status/418 path of the HTTPBin application:
```
curl http://${IP address of the ASM gateway}/status/418 -v
```
  418 Unknown is returned.
3. Run the following command to access the /status/403 path of the HTTPBin application:
```
curl http://${IP address of the ASM gateway}/status/403 -v
```
  403 Forbidden is returned.
4. Run the following command to access the /headers path of the HTTPBin application:
```
curl http://${IP address of the ASM gateway}/headers -H test-header:test-value -v
```
  The response contains the headers carried in the request.
