Touch docker-compose.yml # This has to be in the root directory. docker # A hidden folder to keep most of the Docker configuration.

Now create the three files you’ll need for the Docker configuration: Install an empty Laravel project by opening a new terminal and running the following command:Ĭomposer create-project laravel/laravel docker-tutorial This guide will work with all PHP software and frameworks, though. Let’s use a simple Laravel app to get up and running.

So while I set up this configuration, I’ll try to explain everything that’s happening. Like most other developers, I also like to understand what the code is doing rather than rely on a “magic” command. I like to be in control of everything that’s part of my build to make sure only the essential tools are installed. I’ve tried a couple of these tools, and my experience has been mixed. The other thing you’re going to need for this tutorial is the PHP package management system called composer.Ī few tools will provide you with a Docker configuration without the need to understand it yourself. I think the documentation on the website is clear for all operating systems. Getting Started With Docker for PHPįirst, make sure you have Docker installed on your local system. The ability to have isolated environments between projects, test code with different versions easily, and do both these things with a small footprint are only a few of the reasons Docker has won my heart. VMs work fine, but they’re slow and use a lot of system resources.ĭocker fixes these problems and many more. With these, developers can spin up versions of production software on their local machines. Virtual machines were a step in this direction. For this to happen, local development environments need to be identical (or as close as possible) to the production environments the code runs on. Doing this allows teams to deploy code with confidence. Today, development teams expect to be able to test code in production-like environments. (SSH means Secure Shell, and it’s a way to operate network services on an unsecured network.) Of course, there was very little experience and guidance in terms of good testing and good build pipelines for PHP then. In the dim and distant past, when a developer wanted to make a change to production code, they may have SSHed onto the server and changed the code manually.
