- 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: 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...

Por baixo dos panos, o código `open("./somefile.txt")` cria um objeto que é chamado de "Gerenciador de Contexto".

Quando o bloco `with` finaliza, ele se certifica de fechar o arquivo, mesmo que tenha ocorrido alguma exceção.

- Kubernetes 1.24 is built with go1.18, which will no longer validate certificates signed with a SHA-1 hash algorithm by default. See https://golang.org/doc/go1.18#sha1 for more details.

# Detrás de un Proxy { #behind-a-proxy }

En muchas situaciones, usarías un **proxy** como Traefik o Nginx delante de tu app de FastAPI.

Estos proxies podrían manejar certificados HTTPS y otras cosas.

## Headers reenviados por el Proxy { #proxy-forwarded-headers }

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...
