Containers make it easier to package an application, but its working data still needs a considered place to live. Source files, database records, model caches, and saved outputs have different lifecycles. A storage design becomes easier to understand when you name those differences and keep the important ones visible in your project configuration.
Start with volumes and bind mounts to understand the connection between a running container and its files. Continue with the encryption guide when the data needs protection on the host or in backups. For AI projects, separate downloaded resources from the data and checkpoints you cannot simply recreate. Each guide connects a storage choice to the work it supports.
Treat recovery as part of the development workflow. Record what must persist, which process can change it, and how to obtain a consistent copy. Rebuilding a container should be routine; discovering that the only copy of an important dataset was inside it should not be.
