Advantages of using Docker volumes
- Data Persistence: Volumes ensure that data remains available even after a container is deleted or recreated.
- Data Sharing: Volumes allow data to be shared among multiple containers.
- Performance: Volumes are managed by Docker, providing optimized performance compared to using the host file system directly.
- Backup and Restore: Volumes can be easily backed up and restored, providing a reliable way to manage data.
How to Remove Docker Volumes
Docker volumes are a crucial component in Docker that are used to manage persistent data for containerized applications. They are storage units that can be attached to one or more containers, allowing data to be shared and persist beyond the lifecycle of a single container. They are managed by Docker and are stored outside the container’s writable layer.
They are prominently used for:
- Storing database data to ensure persistence across container restarts.
- Storing logs outside containers
- Mounting source code directories for live development etc.
