caddy 配置文件

先创建目录 /www/k8s/caddy
在目录中创建文件Caddyfile
内容如下(静态页面，或代理其他服务都是在配置文件中配置,根据需要自行选择)

配置静态页面

Caddyfile 内容

foxwho.com:80 {
	root * /srv/foxwho.com
	file_server
}

/srv/foxwho.com : 容器内部 静态文件目录

配置代理服务

Caddyfile 内容

foxwho.com:80 {
	reverse_proxy localhost:5000
}

配置代理服务-二级目录代理

Caddyfile 内容

foxwho.com:80 {
	reverse_proxy /api/* localhost:5000
}

配置代理服务-二级目录代理2

访问 foxwho.com/api/index.html,实际访问的是localhost:5000/index.html

Caddyfile 内容

foxwho.com:80 {
	handle_path /api/* {
	    reverse_proxy  localhost:5000
	}
}

配置静态页面和代理服务

Caddyfile 内容

foxwho.com:80 {
    root * /srv/foxwho.com
	reverse_proxy /api/* localhost:5000
	file_server
}

配置 跳转页面

Caddyfile 内容

foxwho.com:80 {
   redir https://www.{host}{uri}
}

或

foxwho.com:80 {
   redir https://www.foxwho.com{uri}
}

或

foxwho.com:80 {
   redir https://www.baidu.com
}

配置 url 重写

Caddyfile 内容

foxwho.com:80 {
    redir /add     /add/
	redir /remove/ /remove

foxwho.com:80 {
    root * /srv/public
	encode gzip
	php_fastcgi localhost:9000
	file_server

配置 单页面应用

Caddyfile 内容

foxwho.com:80 {
    root * /srv/foxwho.com
	encode gzip
	try_files {path} /index.html
	file_server
}

配置 单页面应用和代理服务

Caddyfile 内容

foxwho.com:80 {
	encode gzip

	handle /api/* {
		reverse_proxy backend:8000
	}

	handle {
		root * /srv/foxwho.com
		try_files {path} /index.html
		file_server
	}
}

同时支持 http 和 https

访问http 不会跳转到 https上
Caddyfile 内容

http://foxwho.com,https://foxwho.com {
	encode gzip

	handle /api/* {
		reverse_proxy backend:8000
	}

	handle {
		root * /srv/foxwho.com
		try_files {path} /index.html
		file_server
	}
}

配置https，且访问http会跳转到https

访问http 不会跳转到 https上
Caddyfile 内容

foxwho.com {
	encode gzip

	handle /api/* {
		reverse_proxy backend:8000
	}

	handle {
		root * /srv/foxwho.com
		try_files {path} /index.html
		file_server
	}
}

Caddyfile 内容

foxwho.com {
    # 日志
    log /data/foxwho.log
	encode gzip

	handle /api/* {
		reverse_proxy backend:8000
	}

		root * /srv/foxwho.com
		try_files {path} /index.html
		file_server

docker 配置

当前目录下新建立 文件和文件夹

touch $(pwd)/Caddyfile
mkdir -p $(pwd)/config
mkdir -p $(pwd)/data
mkdir -p $(pwd)/srv

Caddyfile 文件内容如下

:80 {
    handle_path /api/* {
	    reverse_proxy  https://www.foxwho.com
	}
}

启动

docker run --name caddy \
-d \
-v $(pwd)/Caddyfile:/etc/caddy/Caddyfile \
-v $(pwd)/config:/config \
-v $(pwd)/data:/data \
-v $(pwd)/srv:/srv \
