This means that any data created inside a container’s writable layer is lost forever when the container is removed. While this is great for creating predictable and clean environments, it poses a significant challenge for any application that needs to save data—like databases, user uploads, or logs. To solve this, Docker provides three primary mechanisms for getting data into and out of containers: Volumes, Bind Mounts, and tmpfs mounts.
