Docker Certified Associate Certification Training Course - File System Mount

The video tutorial explains the differences between bind mounts, TMPFS mounts, and volumes in Docker. Bind mounts are limited and rely on the host's file system, while TMPFS mounts are temporary and stored in memory. Volumes are the most efficient for persistent storage, offering easy management and backup. The tutorial also covers how to manage volumes using Docker CLI and provides practical examples of using bind mounts and volumes.

What is a key limitation of bind mounts compared to volumes?

• They are not persistent across container restarts.

• They cannot be used with Docker CLI commands.

• They require manual creation before use.

• They do not allow data sharing between containers.

What happens to data stored in a TMPFS mount when a container stops?

• It is backed up automatically.

• It is saved to the host's file system.

• It is transferred to a volume.

• It is lost as TMPFS is temporary.

Which of the following is an advantage of using Docker volumes?

• They do not require a host directory.

• They are automatically created with containers.

• They can be easily backed up and migrated.

• They are stored in the host's memory.

How can volumes be managed in Docker?

• Through the host's file system.

• Using Docker CLI commands and APIs.

• Through the Docker web interface.

• By editing container configuration files.

What is a characteristic of bind mounts?

• They are managed by Docker CLI commands.

• They are created automatically with containers.

• They rely on the host's file system.

• They are stored outside the host's file system.

Which storage mechanism is best for temporary data that should not persist?

• Named volumes

• TMPFS mounts

• Volumes

• Bind mounts

What is a unique feature of Docker volumes compared to bind mounts?

• They require a specific directory path.

• They are stored in the host's memory.

• They can be mounted in multiple containers simultaneously.

• They are automatically deleted when not in use.
