Strapi, a self-hosted Headless CMS, allows users to maintain it on private servers, with various methods available for setup, including the Command Line Interface (CLI), one-click buttons, or Docker Compose. Docker Compose serves as a command-line tool that organizes multiple Docker containers into applications using a descriptor file, facilitating the creation of self-hosted Strapi projects with any database across different operating systems. The blog post outlines configurations for linking Strapi projects with several databases, such as SQLite, PostgreSQL, MongoDB, MySQL, and MariaDB, providing specific `docker-compose.yaml` file examples for each. Users are encouraged to pull the latest images using `docker-compose pull`, though it's optional, as running `docker-compose up` will automatically pull images. The text concludes with a note that newer versions of Strapi may have been released since the post's publication, and readers are invited to report outdated content.
