Docker is a popular open-source platform for developing, shipping, and running applications. It encapsulates applications and their dependencies in containers to promote consistency across different environments. This consistency helps prevent issues related to dependency conflicts and “it works on my machine” discrepancies.

With Docker, you can define the necessary dependencies and extensions using Dockerfiles. This means your applications have all the required libraries and tools in a reproducible, isolated environment.

Kinsta Application Hosting offers dynamic support for custom Dockerfiles, which allows you to have greater control of your application’s environment. With a Dockerfile, you can use almost any language—you’re not restricted to the languages supported by Nixpacks or Buildpacks.

This hands-on article walks you through how to install and use PHP dependencies and extensions in Docker.

Why use Docker for installing dependencies?

Using Docker to install dependencies has several benefits:

  • Environment consistency — Docker allows you to package your application, its dependencies, and its configurations into a container. This approach ensures that the environment in which your application runs remains consistent across different configurations and systems, including development, testing, and production environments.
  • Ease of setup and dependency resolution — Docker lets you set up your app’s environment on any machine that supports it by specifying all its required dependencies and configurations. As a result, you avoid compatibility issues and the hassle of manually installing dependencies.
  • Version control and isolation — Docker containers encapsulate all dependencies, including their specific versions within the container. This means you can version control your application and its dependencies, promoting reproducibility and eliminating conflicts between different dependency versions.

Additionally, Docker containers provide isolation, which helps eliminate conflicts between dependencies of different applications running on the same system.
