Docker builds LNMP environment: Is single Dockerfile or docker-compose better?

Docker builds LNMP environment: single Dockerfile or docker-compose?

When learning Docker, many developers will try to build LNMP (Linux, Nginx, MySQL, PHP) environments. Two common methods are: integrate all components in a single Dockerfile, or use docker-compose to build and orchestrate PHP, MySQL, and Nginx respectively. This article will compare these two methods and analyze which one is better.

The core problem is to choose the best Dockerfile strategy to build an LNMP environment. Although integrating all components into a Dockerfile may seem simple and easy to use, this approach has some shortcomings.

Why is docker-compose better?

Integrating PHP, MySQL, and Nginx into a Dockerfile will reduce the isolation between components, which is no essential difference from running an integrated environment on a traditional Linux system. In addition, this method will lead to excessive number of mirror layers and expand the image volume, affecting the construction speed and storage space.

In contrast, using docker-compose orchestration, each component has an independent Dockerfile, which ensures isolation, facilitates maintenance and updates, and has a smaller image size, which is more in line with Docker's microservice concept. This method is more flexible, easy to expand and debug, and is also more conducive to team collaboration.

Therefore, for the construction of LNMP development environment, it is recommended to use docker-compose to build PHP, MySQL, and Nginx Dockerfiles respectively to obtain better isolation, maintainability and efficiency.
