TYPO3 administration
Running TYPO3 in Docker
Learn how to run TYPO3 using Docker containers for local development and testing, including step-by-step guides for plain Docker, Docker Compose, and DDEV.
Directory structure
The folder layout of your TYPO3 project depends on how TYPO3 was installed. Composer-based installations use a modern structure that separates code from public files—ideal for deployment workflows and version control. Classic mode keeps everything in a single folder and is easier to set up for beginners.
Both methods are fully supported for production use, however there are security consideration regarding file access when using the classic structure.
