在 Ubuntu 20.04 上运行

安装: https://knative.dev/docs/install/install-serving-with-yaml/

尝试了所有网络层 - 这个是使用 kourier 和 cert-manager 运行的

我安装了“networking-ns-cert”并使用了 DNS01 - 基本上如下: https://knative.dev/docs/install/install-serving-with-yaml/

我确实创建了我的证书,我可以 curl -H "app..mydomain.dev" http(not https)

我注意到您正在连接到https://mydomain.dev,但传递了不同域的主机标头。我的猜测curl是发送mydomain.dev证书的 SNI 请求;由于networking-ns-cert将获取 的通配符证书*.<namespace>.my domain.dev,因此服务器可能没有与 SNI 请求匹配的证书,并关闭 TCP 连接。

尝试使用-kvvto 选项curl(而不是-v)打印更详细的调试信息并绕过一些 SSL 错误。由于您设置了 DNS 和证书,我会尝试:

curl -kvv https://helloworld-go.default.mydomain.dev
