Docker Compose is a versatile tool designed to simplify the development and testing of multi-container applications by using a YAML file to configure application services, allowing developers to manage several containers simultaneously with a single command. Originally developed for Linux but now available on Windows and macOS, Docker Compose enhances portability and allows for isolated environments that closely mimic production settings, facilitating efficient testing and deployment. Its ability to centralize development environments and manage multiple isolated instances on a single host makes it a popular choice among developers. Additionally, Docker Compose supports complex network configurations and data persistence, making it an ideal workflow improvement tool for deploying and managing applications like the headless CMS Strapi. Victor Coisne, VP Marketing at Strapi and former Head of Community at Docker, endorses Docker Compose for its capability to streamline container management and deployment processes, offering a more straightforward and efficient alternative to handling multiple Docker files.
