Docker Volumes for Persistence
Implement Docker volumes to store and manage persistent data for your containerized applications.
Why Persistent Data?
Containers are designed to be light and temporary. When a container is removed, any data stored inside its writable layer is lost forever.
But what if your application needs to save important information, like a database or user files? This is where data persistence comes in!
Introducing Docker Volumes
Docker Volumes are the best way to store application data persistently in Docker. Unlike data stored directly in a container, volumes are managed by Docker and exist independently of any specific container.
- They are stored in a part of the host filesystem managed by Docker.
- They are optimized for I/O performance.
- They are easy to back up or migrate.
