tls1.2 - Knative：启用自动 TLS 证书配置

问题描述

我正在尝试“启用自动 TLS 证书配置”

我有一个工作的 ClusterIssuer（状态：“True”），我可以手动创建证书（状态：“True”）。

环境设置：

Knative: v0.12
Istio: v1.4 (SDS)
cert-manager: v0.13.1

kubectl version                                                               
Client Version: version.Info{Major:"1", Minor:"15", GitVersion:"v1.15.9", GitCommit:"2e808b7cb054ee242b68e62455323aa783991f03", GitTreeState:"clean", BuildDate:"2020-01-18T23:33:14Z", GoVersion:"go1.12.12", Compiler:"gc", Platform:"darwin/amd64"}
Server Version: version.Info{Major:"1", Minor:"15+", GitVersion:"v1.15.9-gke.9", GitCommit:"a9973cbb2722793e2ea08d20880633ca61d3e669", GitTreeState:"clean", BuildDate:"2020-02-07T22:35:02Z", GoVersion:"go1.12.12b4", Compiler:"gc", Platform:"linux/amd64"}

我有以下网关：

apiVersion: networking.istio.io/v1alpha3
kind: Gateway
metadata:
  name: knative-ingress-gateway
  namespace: knative-serving
spec:
  selector:
    istio: ingressgateway
  servers:
  - port:
      number: 80
      name: http
      protocol: HTTP
    hosts:
    - "*"
    tls:
      # Sends 301 redirect for all http requests.
      # Omit to allow http and https.
      httpsRedirect: false
  - port:
      number: 443
      name: https
      protocol: HTTPS
    hosts:
    - "mydomain.com"
    tls:
      mode: SIMPLE
      privateKey: /etc/istio/ingressgateway-certs/tls.key
      serverCertificate: /etc/istio/ingressgateway-certs/tls.crt

并且在申请时：

apiVersion: serving.knative.dev/v1
kind: Service
metadata:
  name: helloworld-go
  namespace: default
spec:
  template:
    spec:
      containers:
      - image: gcr.io/knative-samples/helloworld-go # The URL to the image of the app
        env:
        - name: TARGET
          value: "Go Sample v1"

我可以（注意：httpsRedirect：false）：

curl http://helloworld-go.default.mydomain.com                                       
Hello Go Sample v1!

但是在尝试使用 https 时：

curl https://helloworld-go.default.mydomain.com
curl: (35) LibreSSL SSL_connect: SSL_ERROR_SYSCALL in connection to helloworld-go.default.mydomain.com:443

还：

Knative 文档状态：“在这种模式下，将为每个命名空间配置一个证书，并在 Knative 中重复使用”，但我在任何命名空间中都看不到任何证书。

请注意，kubectl get ksvcurl 是 http 而不是 https：

kubectl get ksvc
NAME            URL                                      LATESTCREATED         LATESTREADY           READY   REASON
helloworld-go   http://helloworld-go.default.mydomain.com   helloworld-go-lxr2n   helloworld-go-lxr2n   True
