Root symlink folder updates and caddy reload not working

[chad (Chad Hurin)]

1. Caddy version (caddy version): v2.2.0

2. How I run Caddy:

caddy start

a. System environment:

Linux 4.15.0-106-generic x86_64

b. Command:

caddy reload

d. My complete Caddyfile or JSON config:

{
    on_demand_tls {
        ask https://fleetwire.io/custom-domain-check
    }
}
https://fleetwire.io {
	@cachedFiles {
	    path *.jpg *.jpeg *.png *.gif *.ico *.svg *.webp
	}

	# root * /var/www/fleetwire.io/current/public
	root * /var/www/fleetwire.io/releases/20201120233219/public


	header {
		Access-Control-Allow-Origin *
		Access-Control-Allow-Methods "GET, POST, PUT, PATCH, OPTIONS"
		Strict-Transport-Security max-age=31536000

		X-Self-Sub false
		Server Avoca
	}

	header @cachedFiles Cache-Control "public, max-age=31536002"

	log {
		output file /var/log/caddy/access2.log
		format console
		level error
	}



	tls {
		on_demand
	}


	encode gzip

    php_fastcgi unix//run/php/php-fpm.sock

    file_server
}

3. The problem I’m having:

I’m using Envoyer to deploy my laravel app. (Introduction | Envoyer)

Envoyer creates and release folder and after done building will create a new symlink at this folder “var/www/fleetwire.io/current/public”.

I reload caddy caddy reload and shows success. My problem has been after the symlink is swapped out caddy doesn’t seem to actually reload.

I have been using the non symlink folder path of the release as you can see in my caddyfile above. I know that caddy isn’t reload bc after i run a build locally I have several new js/css files after webpack runs and after a reload my app breaks bc it is looking for the old css/js. (ex. before push the app.js version as app.asd205449.js and the new app.js version is app.hpflrkt9.js.

4. Error messages and/or full log output:

Caddy only reloads if the configuration actually changed. Otherwise, there’s no reason to reload.

So, Caddy doesn’t work with symlinks as roots then?
Even after a caddy reload command?

Thanks,

[francislavoie]

I think you need the resolve_root_symlink option of php_fastcgi which unfortunately isn’t documented on the site right now - but the change is made in the website source, it’ll be up next time the docs are pushed (probably around the time v2.3 is released).

php_fastcgi unix//run/php/php-fpm.sock {
	resolve_root_symlink
}

Give that a shot and see if it works any better for you.

Nice.

I think that worked. No need to run caddy reload!
