Using Docker with Laravel

Let's take a quick look at how you can successfully use Docker with Laravel. By using Docker for your Laravel app, it will help speed up development and deployment.

This guide is a step by step guide that will walk you through the process of using Docker with Laravel.

Install Docker

The first thing you will need is Docker installed on your machine.

If you're unfamiliar with Docker, you may want to learn more about what Docker is and why you would use Docker.

Create a Laravel project

Let's get your Laravel setup. Simply run the laravel new command

$ laravel new my-laravel-project

This will create a fresh Laravel project called my-laravel-project.

Write a Dockerfile

Now we're going to add a Dockerfile to our Laravel project. The Dockerfile contains all the steps to build an image of our Laravel app.

{tip} We've documented everything we've learned about building Docker images based on our experience building and then deploying countless apps.

For this guide our Dockerfile will be kept short and simple. Add the following Dockerfile to your project directory

FROM php:7

# Install composer
RUN curl -sS | php -- --install-dir=/usr/local/bin --filename=composer

# Enable additional PHP extensions (required for Laravel) 
RUN docker-php-ext-install pdo mbstring

# Copy project files into Docker container
COPY . /app

# Install dependencies 
RUN composer install

# Run our Laravel app
CMD php artisan serve --host= --port=80

Docker Compose

We're just going to jump straight into using Docker Composer to build your image and run your app. This is much more practical and convenient.

Add a docker-compose.yml file to your project

version: "3.7"
    build: .
      - ./:/app
      - "80:80"

    image: mariadb
      - ./storage/data/mysql:/var/lib/mysql
      - "3306:3306"
      MYSQL_DATABASE: laravel
      MYSQL_USER: root
      MYSQL_PASSWORD: secret

Here we're adding two services: web and mysql. The web service will be build using the Dockerfile we created and the mysql service will run the mariadb image.

Build your Docker Image

With your docker-compose.yml file in place, all you need to do now is start a build

$ docker-compose build

This will build an image based on the steps in your Dockerfile.

Run your app

Now everything is built, let's start up your development environment

$ docker-compose up 


Once created, Docker images can be pushed to a Docker registry to be shared with other users or servers.

Push your image to the Docker Hub registry by completing the following steps:

  1. Create a Docker Hub account
  2. Log into Docker Hub with docker login
  3. Push the image to the registry docker-compose push

That's it. Now your image will be on Docker Hub so you can pull and run it from any computer with Docker installed.

$ docker run [your-username]/laravel-project

Of course, the image will need to be re-built and re-pulled as you make changes to your code. You can automate this with automated build tools/services and connect those to an automated deployment tool.

Deployment with Codemason

Codemason is a tool that streamlines the entire process of deploying your Laravel app (building, pulling running Docker images) on the server of your choice.

With Codemason, all you need to do is run git push codemason master and your changes will be deployed to your server.
