我有在Windows的Docker中运行的Kubernetes。
我正在使用NGINX入口控制器,已经应用了mandatory.yaml
和cloud-generic.yaml
。
> kubectl get services -n ingress-nginx
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
ingress-nginx LoadBalancer 10.110.198.161 localhost 80:30037/TCP,443:31218/TCP 5h
我的本地注册表test-app/mock-service:1.0.0
中有一个映像,该映像公开了运行具有单个端点GET /mocks
的服务器的端口8080。使用docker run -d -p 8080:8080 test-app/mock-service:1.0.0
在Docker中运行它可以正常工作,我可以看到预期的结果。
我的意图是使用Kubernetes部署它。
我创建了部署和服务资源:
apiVersion: extensions/v1beta1
kind: Deployment
metadata:
name: test-app-mock-service-deployment
namespace: test-app
spec:
selector:
matchLabels:
app: test-app-mock-service
replicas: 1
template:

labels:
app: test-app-mock-service
spec:
containers:
- name: test-app-mock-service-container
image: "test-app/mock-service:1.0.0"
---
apiVersion: v1
kind: Service
metadata:
name: test-app-mock-service
namespace: test-app
spec:
type: ClusterIP
selector:
app: test-app-mock-service
ports:
- port: 8080
targetPort: 8080
protocol: TCP
还有一个入口资源:
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
name: test-app-ingress
namespace: test-app
annotations:
ingress.kubernetes.io/ssl-redirect: "true"
spec:
rules:
- http:
paths:
- path: /mocks
backend:
serviceName: test-app-mock-service
servicePort: 8080
我可以看到该服务:
> kubectl get services -n test-app
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
test-app-mock-service ClusterIP 10.108.10.246 <none> 8080/TCP 1h
还有吊舱:
> kubectl get pods -n test-app
NAME READY STATUS RESTARTS AGE
test-app-mock-service-deployment-6b9b58fcb9-mdskn 1/1 Running 0 59m
我可以看到入口:
> kubectl describe ingress test-app-ingress -n test-app
Name: test-app-ingress
Namespace: test-app
Address: localhost
Default backend: default-http-backend:80 (<none>)
Rules:
Host Path Backends
---- ---- --------

/mocks test-app-mock-service:8080 (<none>)
Annotations:

kubectl.kubernetes.io/last-applied-configuration: {"apiVersion":"extensions/v1beta1","kind":"Ingress","metadata":{"annotations":{"ingress.kubernetes.io/ssl-redirect":"true"},"name":"test-app-ingress","namespace":"test-app"},"spec":{"rules":[{"http":{"paths":[{"backend":{"serviceName":"test-app-mock-service","servicePort":8080},"path":"/mocks"}]}}]}}
Events:

---- ------ ---- ---- -------
Normal CREATE 1h nginx-ingress-controller Ingress test-app/test-app-ingress
Normal UPDATE 53m (x2 over 1h) nginx-ingress-controller Ingress test-app/test-app-ingress
但是,当我浏览到http://localhost/mocks
时,我得到了308到https://localhost/mocks
,在那里我得到了404。
我不确定入口是否配置错误或是否是另一个问题。

可能发生的情况是SSL部分正在使用SNI,并且由于没有主机或默认的后端集,nginx不知道将请求发送到哪里。您可以通过两件事来解决此问题。
您可以添加注释以为没有主机或路由的请求设置默认后端。有关此文档,请参见https://kubernetes.github.io/ingress-nginx/user-guide/nginx-configuration/annotations/#default-backend。在您的示例中为:
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
name: test-app-ingress
namespace: test-app
annotations:
ingress.kubernetes.io/ssl-redirect: "true"
nginx.ingress.kubernetes.io/default-backend: test-app-mock-service
spec:
rules:
- http:
paths:
- path: /mocks
backend:
serviceName: test-app-mock-service
servicePort: 8080
您的规范不包含TLS主机名。添加一个应该使SNI知道指定的路由规则需要使用什么名称:
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
name: test-app-ingress
namespace: test-app
annotations:
ingress.kubernetes.io/ssl-redirect: "true"
nginx.ingress.kubernetes.io/default-backend: test-app-mock-service
spec:
tls:
- hosts:
- localhost
secretName: tls-secret
rules:
- http:
paths:
- path: /mocks
backend:
serviceName: test-app-mock-service
servicePort: 8080
但是,如果您使用的是自签名证书,则可能需要找到它的名称。您可能需要生成自己的。有关更多信息,请参见https://kubernetes.github.io/ingress-nginx/user-guide/tls/。
