Istio网关无法通过HTTPS连接

通过HTTP在使用Istio的GKE群集中的部署可以正常工作。但是,当我尝试使用具有以下资源的cert-manager保护它时,HTTPS请求失败,例如curl上的状态

`Immediate connect fail for 64:ff9b::2247:fd8a: Network is unreachable
* connect to 34.71.253.138 port 443 failed: Connection refused`.

我应该怎么做才能使其与HTTPS一起使用。

具有以下配置的ClusterIssuer

apiVersion: cert-manager.io/v1alpha2
kind: ClusterIssuer
metadata:
  name: letsencrypt-staging
  namespace: istio-system
spec:
  acme:
    # The ACME server URL
    server: https://acme-staging-v02.api.letsencrypt.org/directory
    # Email address used for ACME registration
    email: iprocureservers@iprocu.re
    # Name of a secret used to store the ACME account private key
    privateKeySecretRef:
      name: letsencrypt-staging
    solvers:
    # ACME DNS-01 provider configurations
    - dns01:
        # Google Cloud DNS
        clouddns:
          # Secret from the google service account key
          serviceAccountSecretRef:
            name: cert-manager-credentials
            key: gcp-dns-admin.json
          # The project in which to update the DNS zone
          project: iprocure-server

这样的证书配置,使证书处于Ready:True状态

apiVersion: cert-manager.io/v1alpha3
kind: Certificate
metadata:
  name: letsencrypt-staging
  namespace: istio-system
spec:
  secretName: letsencrypt-staging
  commonName: "*.iprocure.tk"
  dnsNames:
  - '*.iprocure.tk'
  issuerRef:
    name: letsencrypt-staging
    kind: ClusterIssuer

最后是网关

apiVersion: networking.istio.io/v1alpha3
kind: Gateway
metadata:
  name: iprocure-gateway
  namespace: default
spec:
  selector:
    istio: ingressgateway
  servers:
  - port:
      number: 80
      name: http
      protocol: HTTP
    hosts:
    - "*"
    tls:
      httpsRedirect: false
  - port:
      number: 443
      name: https
      protocol: HTTPS
    hosts:
    - "*"
    tls:
      mode: SIMPLE
      credentialName: letsencrypt-staging

如果我愿意,kubectl describe certificate -n istio-system

    Name:         letsencrypt-staging
    Namespace:    istio-system
    Labels:       <none>
    Annotations:  <none>

运行kubectl get certificates -o wide -n istio-system,会产生

NAME                  READY   SECRET                            ISSUER                              STATUS                                          AGE

答案 0 :(得分:1)

问题

我认为,由于requirements无法使用https,因此如果要在旧版本中将ist-menager与istio一起使用,则必须启用。

解决方案

就像@Yunus Einsteinium在评论中提到的

谢谢您引导我朝着正确的方向前进。使用OSS Istio而不是GKE是一种方法!我设法使HTTPS正常工作!

所以这里的解决方案是使用OOS istio installed with istioctl而不是较旧的istio gke插件。
