nginx-ingress配置4/7层测试

这节我们测试下nginx-ingress的4/7层负载，这里的测试环境主要是barematal场景下使用的nodeport方式。
首先部署一个ingress，这里使用最新的0.21.0版本：

1 2 3 4 5 6 7 8 9

git clone https://github.com/kubernetes/ingress-nginx.git git checkout nginx-0.20.1 cd ~/ingress-nginx/deploy kubectl apply -f mandatory.yaml # baremetal方式部署 # 这里可以修改yaml，指定nodePort，默认是动态生成 kubectl apply -f provider/baremetal/service-nodeport.yaml

注意：0.21.0和之前的版本有了变化，default-backend 不在单独一个pod。所以这里部署成功，默认就一个pod。

部署完成之后，访问测试：

1 2 3 4 5 6 7 8

➜ ~ curl 10.7.12.201:31075 404 Not Found nginx/1.15.6

7层

我们创建两个一个nginx，另一个httpd

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51

vi my-nginx.yaml 粘贴以下内容： apiVersion: extensions/v1beta1 kind: Deployment metadata: name: my-nginx spec: replicas: 1 template: metadata: labels: run: my-nginx spec: containers: - name: my-nginx image: nginx ports: - containerPort: 80 --- apiVersion: v1 kind: Service metadata: name: my-nginx labels: app: my-nginx spec: ports: - port: 80 protocol: TCP name: http selector: run: my-nginx --- apiVersion: extensions/v1beta1 kind: Ingress metadata: name: my-nginx annotations: kubernetes.io/ingress.class: "nginx" # 禁止跳转https nginx.ingress.kubernetes.io/ssl-redirect: "false" spec: rules: - http: paths: - path: / backend: serviceName: my-nginx servicePort: 80

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51

my-httpd.yaml apiVersion: extensions/v1beta1 kind: Deployment metadata: name: my-httpd spec: replicas: 1 template: metadata: labels: run: my-httpd spec: containers: - name: my-httpd image: httpd ports: - containerPort: 80 --- apiVersion: v1 kind: Service metadata: name: my-httpd labels: app: my-httpd spec: type: NodePort ports: - port: 80 protocol: TCP name: http selector: run: my-httpd --- apiVersion: extensions/v1beta1 kind: Ingress metadata: name: my-httpd annotations: kubernetes.io/ingress.class: "nginx" nginx.ingress.kubernetes.io/ssl-redirect: "false" spec: rules: - http: paths: - path: / backend: serviceName: my-httpd servicePort: 80

创建：

1	kubectl apply -f .

查看状态：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

[root@k8s-m1 ingress-nginx]# kubectl get pod NAME READY STATUS RESTARTS AGE busybox 1/1 Running 5 5h1m my-httpd-6b4494fddc-nztf9 1/1 Running 0 11m my-nginx-756f645cd7-v5nvg 1/1 Running 0 8m24s [root@k8s-m1 ingress-nginx]# kubectl get svc NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE kubernetes ClusterIP 10.96.0.1 443/TCP 21d my-httpd NodePort 10.105.105.99 80:31300/TCP 11m my-nginx NodePort 10.100.242.232 80:30750/TCP 8m26s [root@k8s-m1 ingress-nginx]# kubectl get ing NAME HOSTS ADDRESS PORTS AGE my-httpd * 80 12m my-nginx * 80 8m30s

这时配置解析，如果没有dns，直接写入hosts：

1 2	10.7.12.201 my-nginx 10.7.12.201 my-httpd

这时访问：

1 2 3 4

curl my-nginx:31075 curl my-httpd:31075 # curl 10.7.12.201:30175

这时，会出现问题，当curl 10.7.12.201:30175时并不会返回404的页面，而是返回的第一个创建的 ingress 站点内容。

4层
