我正在运行Ingress，它应该连接到Pod中的图像。当我做describe时，它看起来很好，例如
$ kubectl describe svc solar-demo
Name: solar-demo
Namespace: default
Labels: <none>
Annotations: kubectl.kubernetes.io/last-applied-configuration={"apiVersion":"v1","kind":"Service","metadata":{"annotations":{},"name":"solar-demo","namespace":"default"},"spec":{"ports":[{"name":"city","port":3000...
Selector: app=solardemo
Type: ClusterIP
IP: 10.97.245.248
Port: city 3000/TCP
TargetPort: 3000/TCP
Endpoints: 172.17.0.4:3000,172.17.0.6:3000
Port: solar 3001/TCP
TargetPort: 3001/TCP
Endpoints: 172.17.0.4:3001,172.17.0.6:3001
Session Affinity: None
Events: <none>
它甚至可以正确列出我图像的IP地址。但是，当我尝试访问服务时，我只需要一个root即可得到404，这很好，因为当我尝试到达路线
/和/或503时，我没有将map /solar映射到任何东西和/city错误。当我检查日志时，它返回:
$ kubectl logs solar-demo-5845984b94-xp82l solar-svc
npm info it worked if it ends with ok
npm info using npm@5.6.0
npm info using node@v9.11.2
npm info lifecycle nf-images-test@1.0.0~prestart-solar-svc: nf-images-test@1.0.0
npm info lifecycle nf-images-test@1.0.0~start-solar-svc: nf-images-test@1.0.0
> nf-images-test@1.0.0 start-solar-svc /opt/app-root/src
> node solar-svc.js
{"level":30,"time":1530271233676,"msg":"Server listening at http://0.0.0.0:3001","pid":26,"hostname":"solar-demo-5845984b94-xp82l","v":1}
server listening on 3001
对于其他服务也是如此:
$ kubectl logs solar-demo-5845984b94-xp82l api
npm info it worked if it ends with ok
npm info using npm@5.6.0
npm info using node@v9.11.2
npm info lifecycle nf-images-test@1.0.0~prestart-api: nf-images-test@1.0.0
npm info lifecycle nf-images-test@1.0.0~start-api: nf-images-test@1.0.0
> nf-images-test@1.0.0 start-api /opt/app-root/src
> node api.js
{"level":30,"time":1530271244205,"msg":"Server listening at http://0.0.0.0:3000","pid":21,"hostname":"solar-demo-5845984b94-xp82l","v":1}
server listening on 3000
我得到503s，图像从没收到任何请求，就好像
Ingress“认为”每个Pod都掉了一样。我可以检查什么？$ curl -v http://shmukler.example.com/solar
* Trying 192.168.99.101...
* Connected to shmukler.example.com (192.168.99.101) port 80 (#0)

> Accept: */*

请指教。
最佳答案
在注释中，缺少配置:
nginx.org/server-snippet: "proxy_ssl_verify off;"
关于nginx - K8s Ingress服务返回503，在Pod日志中什么也没有，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/51123911/
