我正在尝试在我们的Kubernetes集群中使用TLS。我已经阅读了关于"在Azure Kubernetes服务上创建HTTPS入口控制器"的MS文档(https://learn.microsoft.com/en-us/azure/aks/ingress-tls)。
我已经部署了一个nginx入口控制器，添加了DNS记录并安装了证书管理器。我创建了一个SelfSigned的CA ClusterIssuer，还创建了2个演示应用程序。
当我创建入口路由时，证书会自动创建，并且就绪状态为"True"，但路由不起作用——我无法访问部署了主机名(https://hello-world-ingress.<Ingress_Service_DNS_Name>(的演示应用程序。
自签名ClusterIssuer:
apiVersion: cert-manager.io/v1alpha2
kind: ClusterIssuer
metadata:
name: selfsigned-issuer
spec:
selfSigned: {}
入口路线：
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
name: hello-world-ingress
annotations:
kubernetes.io/ingress.class: nginx
nginx.ingress.kubernetes.io/rewrite-target: /$2
cert-manager.io/cluster-issuer: selfsigned-issuer
spec:
tls:
- hosts:
- hello-world-ingress.<Ingress_Service_DNS_Name>
secretName: tls-secret
rules:
- host: hello-world-ingress.<Ingress_Service_DNS_Name>
http:
paths:
- backend:
serviceName: aks-helloworld
servicePort: 80
path: /(.*)
- backend:
serviceName: aks-helloworld-two
servicePort: 80
path: /hello-world-two(/|$)(.*)
---
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
name: hello-world-ingress-static
annotations:
kubernetes.io/ingress.class: nginx
nginx.ingress.kubernetes.io/rewrite-target: /static/$2
cert-manager.io/cluster-issuer: selfsigned-issuer
spec:
tls:

rules:

serviceName: aks-helloworld
servicePort: 80
path: /static(/|$)(.*)
我已经在我们的域中的GoDaddy上为<Ingress_Service_DNS_Name>(但使用真名(创建了一个指向外部入口控制器服务IP地址的DNS记录。
其余的安装和部署与文档相同。
有人知道为什么它不起作用吗？

唯一看起来可能有问题的是证书管理器日志：
"certificate resource is not owned by this ingress. refusing to update non-owned certificate resource for ingress" "related_resource_kind"="Certificate" "related_resource_name"="tls-secret-selfsigned" "related_resource_namespace"="ingress-basic" "resource_kind"="Ingress" "resource_name"="hello-world-ingress-static" "resource_namespace"="ingress-basic" "
谢谢，

根据提供的信息，我们认为问题是两个进程使用了相同的自签名证书。
您试图在这里实现的是，您希望从两个不同的地方管理您的证书。正如文件所述：
部署TLS入口资源-"有两种主要方法this：使用带ingress填充程序的入口上的注释或直接使用正在创建证书资源。">
因此您的hello-world-ingress可以使用注释：
cert-manager.io/cluster-issuer: selfsigned-issuer
但是helo-world-ingress-static不能，因为证书已经在secretName: tls-secret下创建。
因此，您应该从hello-world-ingress-static中删除注释：
cert-manager.io/cluster-issuer: selfsigned-issuer
因为secretName已经由其他资源创建和管理，所以它会产生利益冲突。在这种情况下，CertificateRequest来自另一个Ingress。
如果这有帮助，请告诉我。
