基于Certbot docker部署letsencrypt证书

仓库地址

https://registry.hub.docker.com/r/certbot/certbot

官方参考

https://certbot.eff.org/docs/install.html#running-with-docker

pull 镜像

docker pull certbot/certbot

基于内置webserver部署

这个方案的坏处是需要启动内置的nginx服务器占用80和443端口.

创建两个目录

/etc/letsencrypt
/var/lib/letsencrypt

运行镜像

docker run -it --rm --name certbot \
            -v "/etc/letsencrypt:/etc/letsencrypt" \
            -v "/var/lib/letsencrypt:/var/lib/letsencrypt" \
            -p 80:80 -p 443:443  \
            certbot/certbot certonly

提问用webserver部署或者用webroot

How would you like to authenticate with the ACME CA?

1: Spin up a temporary webserver (standalone)
2: Place files in webroot directory (webroot)
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Select the appropriate number [1-2] then [enter] (press 'c' to cancel): 1

我们用临时服务器方便点所以选择1, 如果用2的话需要自己设置验证文件.

提示你输入邮箱

Plugins selected: Authenticator standalone, Installer None
Enter email address (used for urgent renewal and security notices)
 (Enter 'c' to cancel):
