# Laravel Sail & Docker

This guide will show Laravel sail and docker environment.

# Introduction

Laravel Sail is a light-weight command-line interface for interacting with Laravel's default Docker development environment. Sail provides a great starting point for building a Laravel application using PHP, MySQL, and Redis without requiring prior Docker experience.

At its heart, Sail is the docker-compose.yml file and the sail script that is stored at the root of your project. The sail script provides a CLI with convenient methods for interacting with the Docker containers defined by the docker-compose.yml file.

Laravel Sail is supported on macOS, Linux, and Windows (via WSL2).

# What is the Docker?

Docker is a tool for running applications and services in small, light-weight "containers" which do not interfere with your local computer's installed software or configuration. This means you don't have to worry about configuring or setting up complicated development tools such as web servers and databases on your personal computer. To get started, you only need to install Docker Desktop (opens new window).

# Installation & Setup

Laravel Sail is automatically installed with all new Laravel applications so you may start using it immediately. To learn how to create a new Laravel application, please consult Laravel's installation documentation (opens new window) for your operating system.

# Installing Sail Into Existing Applications

If you are interested in using Sail with an existing Laravel application, you may simply install Sail using the Composer package manager. Of course, these steps assume that your existing local development environment allows you to install Composer dependencies:

composer require laravel/sail --dev

After Sail has been installed, you may run the sail:install Artisan command. This command will publish Sail's docker-compose.yml file to the root of your application:

php artisan sail:install

Finally, you may start Sail. To continue learning how to use Sail, please continue reading the remainder of this documentation:

./vendor/bin/sail up

# Configuring A Bash Alias

By default, Sail commands are invoked using the vendor/bin/sail script that is included with all new Laravel applications:

./vendor/bin/sail up

However, instead of repeatedly typing vendor/bin/sail to execute Sail commands, you may wish to configure a Bash alias that allows you to execute Sail's commands more easily:

alias sail='bash vendor/bin/sail'

Once the Bash alias has been configured, you may execute Sail commands by simply typing sail. The remainder of this documentation's examples will assume that you have configured this alias:

sail up

# Starting & Stopping Sail

Laravel Sail's docker-compose.yml file defines a Docker variety of containers that work together to help you build Laravel applications. Each of these containers is an entry within the services configuration of your docker-compose.yml file. The laravel.test container is the primary application container that will be serving your application.

Before starting Sail, you should ensure that no other web servers or databases are running on your local computer. To start all of the Docker containers defined in your application's docker-compose.yml file, you should execute the up command:

sail up

To start all of the Docker containers in the background, you may start Sail in "detached" mode:

sail up -d

Once the application's containers have been started, you may access the project in your web browser at: http://localhost (opens new window).

To stop all of the containers, you may simply press Control + C to stop the container's execution. Or, if the containers are running in the background, you may use the down command:

sail down

# How to run the Sneat template with docker?

You can run our template in docker environment using sail. After, successfully installed docker (opens new window) in your system run the below command to install sail and composer in the template.

docker run --rm \
    -u "$(id -u):$(id -g)" \
    -v "$(pwd):/var/www/html" \
    -w /var/www/html \
    laravelsail/php81-composer:latest \
    composer install --ignore-platform-reqs

In the root directory, you will find a file named .env.example, rename the given file name to .env and run the following command to generate the key (and you can also edit your database credentials here).

php artisan key:generate

By running the following command, you will be able to get all the dependencies in your node_modules folder:

npm install

To run the project, you need to run following command in the project directory. It will compile the php files & all the other project files. If you are making any changes in any of the php file then you need to run the given command again.

npm run dev

Now, run the below command to create docker container and serve the template.

alias sail='bash vendor/bin/sail'  //created alias

sail up
