部署 Knative 服务

在本教程中，您将部署一个 Hello world Knative服务，该服务接受环境变量TARGET并打印Hello ${TARGET}!

knYAML

运行命令部署服务:

kn service create hello \
--image gcr.io/knative-samples/helloworld-go \
--port 8080 \
--env TARGET=World

Expected output

Service hello created to latest revision 'hello-world' is available at URL:
http://hello.default.${LOADBALANCER_IP}.sslip.io

The value of ${LOADBALANCER_IP} above depends on your type of cluster, for kind it will be 127.0.0.1 for minikube depends on the local tunnel.

1. 将以下YAML复制到名为hello.yaml的文件中:

   apiVersion: serving.knative.dev/v1
   kind: Service
   metadata:
     name: hello
   spec:
     template:
       spec:
         containers:
           - image: gcr.io/knative-samples/helloworld-go
             ports:
               - containerPort: 8080
             env:
               - name: TARGET
                 value: "World"
   

2. 运行命令部署Knative Service:

   kubectl apply -f hello.yaml
   

   Expected output

   service.serving.knative.dev/hello created
