Let's-Encrypt生成免费ssl证书

更新：2019-07-18

任何人都可以基于 ACME 协议实现一个客户端，官方推荐的客户端是Certbot

# 启动nginx注意开放443端口
docker run -d --restart unless-stopped --name nginx -p 80:80 -p 1935:1935 -p 443:443 -v /data/.nginx/letsencrypt:/etc/letsencrypt  -v /data/.nginx/conf.d:/etc/nginx/conf.d -v /var/log/nginx:/var/log/nginx registry.cn-hangzhou.aliyuncs.com/985/nginx-1.16.0:rtmp

您看到时，该文档可能已经过时，最新的cloudflare客户端不支持免费域名使用API，需手工加入TXT记录
