Sets which file system should be used for performing file I/O.

This could let you connect to a remote filesystem running in the cloud, or a database with a file-like interface, or even to read from files embedded within the Caddy binary.

First, you must declare a file system name using the filesystem global option, then you can use this directive to specify which file system to use.

This directive is often used in conjunction with the file_server directive to serve static files, or the try_files directive to perform rewrites based on the existence of files. Typically also used with root directive to set the root path within the file system.


fs [<matcher>] <filesystem>


Using an file system named foo, using an imaginary module named custom which might require authentication:

	filesystem foo custom {
		api_key abc123
} {
	fs foo
	root /srv

To only serve images from the foo file system, and the rest from the default file system: {
	fs /images* foo
	root /srv
