Q- How can we store container data in memory using docker volume

-tmpfs is the filesystem where the mounts will be stored in memory only while running the container, and it will be used at runtime.
-Data from tmpfs mount will not written to the disk and data from tmpfs will be lost once the container stops.

docker run -d --name docker_image_name--mount source=source_dir_path,target=target_dir_path ubuntu

Docker Image - Day 2

Docker image will have filesystems(root fs, user fs & app fs) and parameters
It will be identified with unique ID(docker imageID)
Docker Images are multi-layered files, which are used to create the containers
All the layers will be merged into one layer while creating the container
Sha-256 Algorithm is used for creating docker image
