Docker部署

docker run -d --restart=always --privileged --net=host -v /data/caddy/data:/data -v /data/caddy/config/Caddyfile:/etc/caddy/Caddyfile -v /data/caddy/config/vhosts:/etc/caddy/vhosts -v /data/caddy/logs:/logs caddy:latest

先准备Caddyfile配置文件

data目录可放静态资源文件
vhosts目录放各站点的配置文件和ssl证书文件
logs目录放caddy日志文件

只需一个邮箱可自动申请并配置https访问
自用整理的Caddyfile配置文件，Caddyfile语法可参考官网教程

Caddyfile

日志

(LOG) {
    log {
        format json {
            time_local
            time_format wall_milli
        }
        output file "/logs/{args.0}/access.log" {
            roll_size 100mb
            roll_local_time
            roll_keep 3
            roll_keep_for 30d
        }
    }
}

(GZIP) {
    encode zstd gzip
}

import ./vhosts/*.conf

本站反代配置示例

https://host {
    import GZIP
    import LOG "host"
    tls /etc/caddy/vhosts/host.pem /etc/caddy/vhosts/host.key
    reverse_proxy XXXXX:XX
}

自动申请ssl证书配置示例

https://域名 {
    import GZIP
    import LOG "域名"
    tls 邮箱
    reverse_proxy XXXXX:XX
}
