📝 Task 1: Create Bind Mount

Bind mount is used to link a folder from the host system to the container.

Steps:

Create a folder on the host system.
Mount it inside the container using bind mount.
Access the folder inside the container.

📝 Task 2: Use Volume in Container

Docker volumes are used to store container data permanently.

Steps:

Create a Docker volume.
Attach the volume to a container.
Store data inside the volume.
Verify the data.

📝 Task 3: Inspect Volume

Volume inspection is used to see details of a volume.

Steps:

Use inspect command on volume.
Check mount path and configuration.

📝 Task 4: Create Tmpfs Mount

Tmpfs mount stores data temporarily in memory.

Steps:

Run container using tmpfs mount.
Store temporary data.
Verify that data is removed after container stops.
