9.3. 验证部署

创建一个新项目

$ oc new-project hello-world

部署 hello world 应用：

$ oc new-app -n hello-world --image=docker.io/openshift/hello-openshift

为 AWS ALB 配置 NodePort 服务以连接：

$ cat << EOF | oc apply -f -
apiVersion: v1
kind: Service
metadata:
  name: hello-openshift-nodeport
  namespace: hello-world
spec:
  ports:
    - port: 80
      targetPort: 8080
      protocol: TCP
  type: NodePort
  selector:
    deployment: hello-openshift
EOF

使用 AWS Load Balancer Operator 部署 AWS ALB：

$ cat << EOF | oc apply -f -
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: hello-openshift-alb
  namespace: hello-world
  annotations:
    alb.ingress.kubernetes.io/scheme: internet-facing
spec:
  ingressClassName: alb
  rules:
    - http:
        paths:
          - path: /
            pathType: Exact
            backend:
              service:
                name: hello-openshift-nodeport
                port:
                  number: 80
EOF

curl AWS ALB Ingress 端点，以验证 hello world 应用程序是否可访问：

$ INGRESS=$(oc -n hello-world get ingress hello-openshift-alb \
    -o jsonpath='{.status.loadBalancer.ingress[0].hostname}')
$ curl "http://${INGRESS}"

Hello OpenShift!

为您的 hello world 应用程序部署 AWS NLB ：

$ cat << EOF | oc apply -f -
apiVersion: v1
kind: Service
metadata:
  name: hello-openshift-nlb
  namespace: hello-world
  annotations:
    service.beta.kubernetes.io/aws-load-balancer-type: external
    service.beta.kubernetes.io/aws-load-balancer-nlb-target-type: instance
    service.beta.kubernetes.io/aws-load-balancer-scheme: internet-facing
spec:
  ports:
    - port: 80
      targetPort: 8080
      protocol: TCP
  type: LoadBalancer
  selector:
    deployment: hello-openshift
EOF

测试 AWS NLB 端点：

$ NLB=$(oc -n hello-world get service hello-openshift-nlb \
  -o jsonpath='{.status.loadBalancer.ingress[0].hostname}')
$ curl "http://${NLB}"

Hello OpenShift!
