This package exposes a few helpful Artisan commands to manage multiple Laravel Sail applications running concurrently on your local environment. This is all powered by a Traefik Docker container acting as a reverse proxy, letting you map custom domain names to your different Laravel applications and handling the incoming traffic to them.

Laravel Sail has pretty much become the standard for starting up development environments for new Laravel projects. Under the hood it's using Docker and Docker Compose to manage services and dependencies for your project, booting up containers to handle local traffic and serve your application.
I enjoy using it, but there's a slight problem I ran into the other day with it, and that's running multiple applications locally at the same time. When Sail boots up, a port is bound from your local machine into the Docker container that the application is running on (by default, it's :80). If you go and try to boot up another Laravel application with Sail, it'll kick back an error because that port is already taken.
Now, you can go ahead and change that port by adding in a
APP_PORT entry to your project's env file, but that comes with a caveat. Depending on what you're doing (in my case, two applications communicating with one another), modern browsers handle localhost with two different ports as completely separate domains. Instead, what I wanted was something like
dashboard.app.localhost. So, I decided to build Fleet!
After installing a new Laravel project (or using an existing one with Sail installed), open up a terminal window and navigate to your project's root. Then, install Fleet with Composer:
composer require aschmelyun/fleet
Next, you'll want to make sure that any running Sail instances have been stopped. Now we can go ahead and add Fleet support to our first application. Again in the project root, use the following command:
php artisan fleet:add
During setup you'll be prompted to enter in a domain name of your choosing. Alternatively, you can pass it in through a command-line argument:
php artisan fleet:add my-app.localhost
Note: If you chose a domain that doesn't end in .localhost, you will need to add an entry to your hosts file to direct traffic to 127.0.0.1!
After the setup finishes, you can start up Sail just like normal:
After the initialization finishes up, your app should be now be available at the domain you provided!
By default, whenever you use
fleet:add, a Docker network and container are both started to handle the traffic from your local domain name(s). There are a few additional Artisan commands that you can use to manage Traefik or remove Fleet support from your application.
php artisan fleet:startboots up the Traefik container and network that normally start when using fleet:add
php artisan fleet:removeremoves Fleet support from an application and returns it back to the default Sail setup
php artisan fleet:stopstops all Fleet containers and networks currently running on your system
How's it work?
fleet:add command is ran Fleet parses your application's
docker-compose.yml file and makes some adjustments to it. The port binding for the app service container is removed, and labels are added in to support mapping for the custom domain name you provided during setup. Also a mapping to an external Docker network is added to the array of networks.
After that finishes up successfully, it runs the
fleet:start command. This spins up both a Docker network and container called
fleet. The container is running Traefik, a reverse-proxy application written in Go. This attaches to the network of the same name. You're then told that you can spin up Sail just like you would normally.
sail up again, this time your application isn't exposed via a port binding. Instead, Traefik determines that the container is spinning up and using the labels that were added to the service in the
docker-compose.yml file, sets up a traffic map from your local environment to the container based on the custom domain you set.
So if you set your domain to
my-app.localhost for one of your Laravel applications running in Sail, visiting that domain will display that Laravel app. But going to a different
.localhost domain will result in a 404 (until you set it up 😉).
So, that's Fleet! If you end up using it and have any questions or comments, please feel free to let me know by messaging me on Twitter or opening up an issue in the GitHub repo. If you want to know more about Traefik and how to use it to manage multiple local development sites, I published a video on that not too long ago.
