几个月前我配置了自动 SSL 证书管理，如下所述：http: //docs.cert-manager.io/en/latest/tutorials/acme/dns-validation.html
for domain: <myhost>.comand dev.<myhost>.com. 所以我有两个命名空间：prodfor<myhost>.com和
devfor dev.<myhost>.com。在每个命名空间中，我都有入口控制器和Certificate资源来将证书存储为机密。它工作正常并ClusterIssuer自动更新证书。
但是几天前我尝试添加新域：test.<myhost>.com在名称空间中，入口和证书的配置与或名称空间test中完全相同（期望主机名和名称空间）：proddev
apiVersion: extensions/v1beta1
kind: Ingress

nginx.ingress.kubernetes.io/proxy-read-timeout: "600"
nginx.ingress.kubernetes.io/proxy-send-timeout: "600"

apiVersion: certmanager.k8s.io/v1alpha1
kind: Certificate
metadata:
name: cert-letsencrypt
namespace: test
spec:
secretName: letsencrypt-tls
issuerRef:
name: letsencrypt-prod-dns
kind: ClusterIssuer
commonName: 'test.<myhost>.com'
dnsNames:
- test.<myhost>.com
acme:
config:
- dns01:
provider: dns
domains:
- test.<myhost>.com
并且此配置不起作用：无法秘密找到证书，入口正在使用“app-ingress-fake-certificate”。
cert-managerpod 显示很多类似的错误：
pkg/client/informers/externalversions/factory.go:72: Failed to list *v1alpha1.Challenge: challenges.certmanager.k8s.io is forbidden: User "system:serviceaccount:kube-system:cert-manager" cannot list challenges.certmanager.k8s.io at the cluster scope
pkg/client/informers/externalversions/factory.go:72: Failed to list *v1alpha1.Order: orders.certmanager.k8s.io is forbidden: User "system:serviceaccount:kube-system:cert-manager" cannot list orders.certmanager.k8s.io at the cluster scope
并且certificate没有尝试获得证书（kubectl describe -ntest cert-letsencrypt）：
API Version: certmanager.k8s.io/v1alpha1
Kind: Certificate
Metadata: ...
Spec:
Acme:
Config:
Dns 01:
Provider: dns
Domains:
test.<myhost>.com
Common Name: test.<myhost>.com
Dns Names:
test.<myhost>.com
Issuer Ref:
Kind: ClusterIssuer
Name: letsencrypt-prod-dns
Secret Name: letsencrypt-tls
Events: <none>
它应该具有作为其他命名空间上的证书的任何状态。
我不明白为什么这个配置以前可以工作，但现在不能工作。
我不确定它是否相关，但我在几周前使用 kops 更新了 kubernetes，当前版本是：
