- Kubeadm: during execution of the "check expiration" command, treat the etcd CA as external if there is a missing etcd CA key file (etcd/ca.key) and perform the proper validation on certificates signed by the etcd CA. Additionally, make sure that the CA for all...

이렇게 하면 TLS Termination Proxy가 **여러 도메인**에 대한 HTTPS와 인증서를 **여러 애플리케이션**에 대해 처리하고, 각 경우에 맞는 애플리케이션으로 요청을 전달할 수 있습니다.

### 인증서 갱신 { #certificate-renewal }

미래의 어느 시점에는 각 인증서가 **만료**됩니다(획득 후 약 3개월).

그 다음에는 또 다른 프로그램(경우에 따라 별도 프로그램일 수도 있고, 경우에 따라 같은 TLS Termination Proxy일 수도 있습니다)이 Let's Encrypt와 통신하여 인증서를 갱신합니다.

- Fixes an issue where the vsphere cloud provider will not trust a certificate if:
  - The issuer of the certificate is unknown (x509.UnknownAuthorityError)
  - The requested name does not match the set of authorized names (x509.HostnameError)

- Kubeadm: make etcd pod request 100m CPU,...

o.example.net` to ensure the browser receives a valid reachable URL. Similarly, if your TLS certificates do not have the IP SAN for the MinIO server host, the MinIO Console may fail to validate the connection to the server. Use the `MINIO_SERVER_URL` environment variable and specify the proxy-accessible hostname of the MinIO server to allow the Console to use the MinIO server API using the TLS certificate. For example: `export MINIO_SERVER_URL="https://minio.example.net"` | Dashboard | Creating a...
