你可以用作 TLS 终止代理的一些选项包括：

* Traefik（也可以处理证书更新）
* Caddy（也可以处理证书更新）
* Nginx
* HAProxy

## Let's Encrypt

在 Let's Encrypt 之前，这些 **HTTPS 证书** 由受信任的第三方出售。

过去，获得这些证书的过程非常繁琐，需要大量的文书工作，而且证书非常昂贵。

但随后 **<a href="https://letsencrypt.org/" class="external-link" target="_blank">Let's Encrypt</a>** 创建了。

它是 Linux 基金会的一个项目。 它以自动方式免费提供 **HTTPS 证书**。 这些证书可以使用所有符合标准的安全加密，并且有效期很短（大约 3 个月），因此**安全性实际上更好**，因为它们的生命周期缩短了。

* Nginx
* HAProxy

## Let's Encrypt { #lets-encrypt }

Antes de Let's Encrypt, estos **certificados HTTPS** eran vendidos por terceros.

El proceso para adquirir uno de estos certificados solía ser complicado, requerir bastante papeleo y los certificados eran bastante costosos.

Pero luego se creó **<a href="https://letsencrypt.org/" class="external-link" target="_blank">Let's Encrypt</a>**.

- In `kube-apiserver`, custom resources can now be specified in the `--encryption-provider-config` file and can be encrypted in etcd. ([#113015](https://github.com/kubernetes/kubernetes/pull/113015), [@ritazh](https://github.com/ritazh))

* Traefik（証明書の更新も対応）
* Caddy (証明書の更新も対応)
* Nginx
* HAProxy


## Let's Encrypt

Let's Encrypt以前は、これらの**HTTPS証明書**は信頼できる第三者によって販売されていました。

これらの証明書を取得するための手続きは面倒で、かなりの書類を必要とし、証明書はかなり高価なものでした。

しかしその後、**<a href="https://letsencrypt.org/" class="external-link" target="_blank">Let's Encrypt</a>** が作られました。
