Easy Docker Drupal Setup: A Step-by-Step Guide
Introduction
Setting up a Drupal site with Docker is now much easier, thanks to ready-made Docker images and new ways to handle configuration.
You can use Docker when you start a new Drupal installation or when you work on an existing one. This helps keep things the same across different places where your Drupal application runs.
By setting up project folders, environment variables, and web servers the right way, you get a strong and simple setup. This easy guide will show you each step so your Drupal site will work well on Docker.
Understanding Drupal Docker: What & Why
A strong setup in web development is to use Drupal with Docker. This makes it much easier to manage complex applications. You can put your full Drupal site, its database, and the web server into their own containers. This keeps all parts separated but working together. By pulling Docker images from Docker Hub, you make sure every setup is the same. You can also repeat your setup any time you need.
With this combo, you can follow best practices and boost your workflow. It is easy to personalize your local development environment. The setup is good for testing new things and helps with version control. This way, the team can try changes without risk and go back to old versions if needed. The setup lets your Drupal site run smoother, both for work and for learning new skills with Docker.
What is Docker, and How Does it work with Drupal?
Docker is a tool that lets you run applications like Drupal in containers—self-contained units with everything the app needs. This avoids the “it works on my machine” problem by ensuring every environment is the same.
For Drupal, you usually run separate containers for the web server (like Apache), PHP, and the database (like MySQL). These containers work together but stay isolated, making it easier to manage and debug.
Using Docker Compose, you define all these containers in one docker-compose.yml file. This makes starting, stopping, or changing your Drupal setup simple and consistent across machines or teams. Docker also offers prebuilt images for Drupal and related services, saving setup time.
Benefits of Using Docker for Drupal Development
Leveraging Docker containers for Drupal gives you many good benefits:
- Consistency Across Workflows: Docker keeps each Drupal project separate from others. That means all the needed pieces for your project are in one place. This setup gets rid of configuration problems and helps you have the same local development environment each time.
- Efficient Version Control: With versioned containers, developers track what changes in their Drupal setups over the year. This way, there is less chance for mistakes, and you always know what is new.
- Enhanced Portability: Docker containers copy your environment to other systems like Linux. You get the same behavior and setup on each one. This makes it easy to go from one system to another.
- Streamlined Workflows: When you use pre-built Docker compose files, it is simple to link the Drupal application and the MySQL database. This setup helps people work together and get going fast.
Docker follows best practices in Drupal development because it gives you the same tools for deployment or when building your local development environment. Its scalable features help developers work on their Drupal setup, manage complex workflows, and run bigger systems with ease.
With Docker, it is easier to work, make changes, and keep everything in one place.
Prerequisites for a Successful Drupal Docker Setup
Before you start, make sure your system is ready for Docker and Drupal. You need to have tools like git, Docker Compose, and PHP installed. The project directory should have the right structure. It should include configuration files, site templates, and all your database settings.
Getting ready is important. Have your needed credentials and files ready. Pick the right containers, too. This helps make the setup work well. If you skip these steps, your Drupal Docker setup can be hard to handle.
System Requirements and Software Installation
Meeting the system’s needs is important if you want to use Docker with Drupal in the right way. You can check these basics in the table below.
| Requirement | Details |
|---|---|
| Operating System | Linux, Windows, or macOS that Docker supports |
| PHP Version | At least v7.4 so your images all work well |
| Database Requirement | Use MySQL or MariaDB set up inside the containers |
| Version Control Tools | Use Git to track any changes |
Start by installing Git and Docker Compose through your usual package manager. Make a new project directory where you keep all setup files.
If you want things to go smoothly, get every needed repository from Docker Hub and set it up for your system. Be sure to set the right permissions and environment details so your Docker workflow works well every time.
Choosing the Best Docker-Based Local Environment for Drupal
Picking a good local development environment is key when you manage a Drupal site. You should think about a few things:
- Existing Project Requirements: Pick your environment based on the modules you need, the way your database is set up, or how old projects work.
- Efficiency of Docker Images: Using ready-made docker images from Docker Hub can make installing easier and save you time during setup.
- Developer Workflow: When your containers have tools like phpMyAdmin or Apache Solr, it can help your team work better.
When you use Docker images that are already set up, the process goes faster. Even so, building a custom solution can let you do more if your project is different. Choose a local development environment for your Drupal site that matches what you need.
This way, your setup and workflow will keep up as your site grows, all while staying safe and easy to use.
Setting Up Your Project Directory for Docker Drupal
Organising the project directory is important when you want to use Docker with Drupal. Most of the time, you will need to have folders for things like database dumps, templates, modules, and documentation. When you separate files in this way, you make the work much easier. This will be helpful for stopping errors in the future when you set up something again.
You should also make sure the directory is set up to follow version control rules. It is good to use .gitignore files, so you do not track files you do not need. This will help you keep every version in sync when going from local to staging or production setups. This way, you can work better with different setups and keep your project directory for Drupal clean.
Organizing Folders and Files for Drupal Projects
A good project directory helps you build and manage your Drupal site in a better way. When you make folders for things like configurations, modules, and themes, your workflow gets easier. This setup helps with version control and is good for people who work together on the same project.
When you use the same naming style for all folders and files, it is simple to find your way around the project. This way, you are less likely to lose track of any sensitive information.
Keeping a clear order in your directories not only keeps things tidy but also follows best practices for Drupal and Docker. This helps your Docker environment work smoothly right from the start and through the whole development process.
Downloading Official Drupal Images from Docker Hub
Accessing Docker Hub’s official Drupal images helps make the setup quick and easy. These images come ready to use, so you do not have to set up everything from the start. Begin by picking the Drupal image version you want. For example, you can get Drupal-8, Drupal-10, or Drupal-latest. Download it from the repository.
You can use the command line to do this job fast. Type “docker pull drupal:latest” and you will get all the needed parts linked to your project directory. After downloading, check if the image works well with your current workflow and the modules you use.
Many times, these images have web servers and PHP inside. This can save you a lot of time, because you do not have to set it up by hand. You also make your setup the same on all machines. This way, there are fewer problems when moving between different parts of your project. Connecting containers is easier, and your work stays steady as you go through each step.
Creating a docker-compose.yml for Drupal
A good docker-compose.yml The file is important when you set up your Drupal environment. This file lets you organize all the Docker containers you need, like the web server and the MySQL database. It also helps these services talk to each other so everything in the local development environment works well.
When you add environment variables in this configuration, it is easier to handle things like sensitive information. This includes things such as MySQL database passwords and other settings that your Drupal application uses.
If you follow best practices for making this configuration, you can set up a stronger local development environment. This will make it easy to deploy and grow your Drupal application when you need to use it in new places or with more users.
Defining Services (Web, Database, and Volumes)
Defining services in your Docker setup is important for making your Drupal site easier to manage. The web server, usually Nginx or Apache, lets you run the Drupal site and send it out to people over HTTP. The MySQL database is the part that holds all the main data for your Drupal installation.
When you set up volumes, your files and data stay safe, even when you start or stop the Docker containers. This helps to keep your workflow smooth and your settings and files safe.
By using these services together, you can build a strong local development environment. It helps you work well, keep your Drupal projects on track, and protect any sensitive information you have.
Configuring Environment Variables for Drupal Containers
Setting up environment variables is an important part of your Drupal setup. They help you run your Drupal containers in a smooth way. The environment variables let you set key things such as the database name, username, and password. This makes your workflow safer and steady.
It is good to use an .env file to keep sensitive information safe. For example, you can use it to store your MySQL username and password. This stops others from seeing that information in your code. This is one of the best practices you can follow.
This way of working keeps your local development environment tidy. It also makes it easier to deploy your project to different servers. When your environment variables are set up the right way, your Drupal site works better and is more reliable.
Building and Running Your Docker Drupal Containers
When you use Docker to run your Drupal site, it can really change the way you do local work. All you have to do is go to the command line and use the docker-compose up command. This will let Docker download the right images from Docker Hub. After the containers start, you just need to open your web browser and go to the set port. Now, you can reach the Drupal installation.
If you want to keep your data even after starting and stopping containers, use Docker Compose volumes. This keeps your database and files safe. It also keeps your workflow smooth. Because of this, every deployment goes well.
Launching Containers and Accessing Drupal Locally
To start your Drupal site locally with Docker, open your terminal, go to your project directory, and run:docker-compose up
This command starts all defined containers—typically the web server, PHP, and MySQL.
Once running, open a browser and go to http://localhost:8080 (or the port you set) to view your Drupal site. This allows you to develop, test, and debug modules or themes in real time.
Persisting Data with Docker Compose Volumes
Docker volumes store your data outside the container, so it doesn’t get lost when containers stop or restart. For example, linking MySQL to a volume ensures your Drupal database is saved even if the container is rebuilt.
You can define volumes in your docker-compose.yml file and map them to a folder on your local machine. This approach keeps your data safe, makes backups easier, and improves the reliability of your Drupal development environment.
Advanced Configuration for Drupal Docker Environments
Setting up the best Drupal Docker environment often needs some advanced setup steps. When you use a multisite configuration, you can run many Drupal sites from one codebase. Each site will still have its own database. This is good because it helps manage your resources and keeps things simple.
When you use custom Docker images for different versions of Drupal, like 7, 8, 10, or 11, the setup for each project gets easier. You make sure each project has the right things it needs to work. It also helps everything be set up the right way.
To make your workflow better, use best practices like version control and Docker Compose in your Drupal projects. This makes your setup faster and keeps it safe when you are working with sensitive information inside your containers.
Setting Up Multisite with Drupal & Docker
Setting up a Drupal multisite with Docker helps make it easy to run many sites from one install. When you use Docker images and set up your project directory in the right way, each Drupal site can be separate, but still use the same main code and modules.
You can also put environment variables in the env file. This helps keep sensitive information, like database logins, safe. The directory stays organized and simple. It is easy to do a deployment or use version control. Updates work smoothly this way. Using this method in your cms makes the workflow better and faster for everyone working on the Drupal sites.
Customizing Docker Images for Drupal 7, 8, 10, and 11
Making Docker images especially for different versions of Drupal requires a good understanding of what makes each version different. It is best practice to add version control to your Dockerfile. This helps make sure your Drupal, its modules, and templates all work together without trouble.
You should set up PHP, Nginx, and MySQL in the best way that fits each Drupal setup. You can use environmental variables in the .env file. These can be for things like database names, usernames, and passwords, which are all sensitive information. This way of working helps build a strong and flexible Drupal development environment.
CI/CD Integration: Automating Builds with Drupal Docker
Integrating CI/CD into a Docker Drupal setup makes the deployment process smoother and helps everyone work faster. When you use tools like CircleCI, you can automate builds and keep the workflow strong. Developers can set up build steps in configuration files. This gives them clear control over how Docker images are deployed.
Doing this helps cut down on mistakes people might make and keeps things steady across different places. Every time you push code to the repository, the pipeline runs right away. This means deployments happen fast and easily. It also fits the changing needs of Drupal, while keeping sensitive information safe.
Using CircleCI for Automated Drupal Docker Deployments
Integrating CircleCI into your deployment pipeline makes it easier to handle a Drupal site when you use Docker. It helps automate your builds. This way, developers can make sure that the Docker images get deployed the same way every time. This reduces mistakes that can happen if things are done by hand.
When you use the configuration files in CircleCI, you can set up your workflow to include tasks like testing, checking PHP code (linting), and pushing your Docker images to Docker Hub. With this setup, you get better version control and also help keep sensitive information safe.
It also makes sure that your Drupal application gets rolled out smoothly and safely in any environment. This workflow helps your team use new features and updates for your Drupal site without trouble.
Conclusion
