Docker 自动更新 Let’s Encrypt

在nginx的 docker run 中添加webroot和配置文件挂载

-v $PWD/nginx/letsencrypt/:/var/www/letsencrypt:ro \
-v $PWD/letsencrypt/etc/:/etc/nginx/letsencrypt/:ro \

在nginx中将wwwroot发布出去

location ^~ /.well-known/ {
    root /var/www/letsencrypt/;
}

在nginx中配置证书文件

ssl_certificate letsencrypt/live/www.yaoge123.com/fullchain.pem;
ssl_certificate_key letsencrypt/live/www.yaoge123.com/privkey.pem;

创建 certbot 的docker run脚本，以后只要周期性运行这个脚本就可以自动更新证书了

#!/bin/sh
cd $(dirname $0)
pwd

docker run -it --rm \
	-v $PWD/letsencrypt/etc:/etc/letsencrypt \
	-v $PWD/letsencrypt/lib:/var/lib/letsencrypt \
	-v $PWD/letsencrypt/log:/var/log/letsencrypt \
	-v $PWD/nginx/letsencrypt:/var/www \
	certbot/certbot \
	certonly --webroot \
	--email yaoge123@example.com --agree-tos --no-eff-email \
	--webroot-path=/var/www/ \
	-n \
	--domains www.yaoge123.com
docker kill --signal=HUP nginx
