Caddyfile

Caddyfile Configuration

Caddy can be configured in multiple ways. The preferred way is by creating and managing a configuration file named Caddyfile.

View Default Config File

The default Caddyfile file that comes with the initial Caddy installation can be located at /etc/caddy/Caddyfile. Take a look at the file with:

cat /etc/caddy/Caddyfile

Contents of /etc/caddy/Caddyfile

# The Caddyfile is an easy way to configure your Caddy web server.
#
# Unless the file starts with a global options block, the first
# uncommented line is always the address of your site.
#
# To use your own domain name (with automatic HTTPS), first make
# sure your domain's A/AAAA DNS records are properly pointed to
# this machine's public IP, then replace ":80" below with your
# domain name.

:80 {
	# Set this path to your site's directory.
	root * /usr/share/caddy

	# Enable the static file server.
	file_server

	# Another common task is to set up a reverse proxy:
	# reverse_proxy localhost:8080

	# Or serve a PHP site through php-fpm:
	# php_fastcgi localhost:9000
}

# Refer to the Caddy docs for more information:
# https://caddyserver.com/docs/caddyfile

Lots of lines within this file are commented out notes. This default Caddyfile is meant to serve as an example to guide the configuration needs of the user.

Ignoring the commented out lines the file contents are:

:80 {
  root * /usr/share/caddy
  file_server
}

This particular configuartion file is:

• Listening on port 80 (the default HTTP port)
• Using the path /usr/share/caddy for the site directory
• Enabling the static file server with the file_server directive

This specific configuraiton is stating that all requests made to port 80 are requesting files at the directory /usr/share/caddy/. Whatever files live in that directory will be matched up with any HTTP requests that hit this web server on port 80.
