Learn all there is to know about Docker and containers from the bottom up. In this course, you'll learn what containers are and why they're great, as well as how to utilize Docker to create custom containers and images.

1. Docker Crash Course
By : Vishwas Narayan

2. Today we are filled with the problem statement

7. Softwares has different rule on different system
● Different Packages
● Version control
● Running the container for the ease of using them
● Running the container for the nature of it being more flexible for the
development.

10. So now lets jump on to the questions
What is dockerfile?
What is a container?
What is a docker image?

11. Why docker?

15. So it just built to be
Independent of Dependencies and also Host OS

17. From Dev To Ops
PHYSICAL VIRTUAL CLOUD
Any Application

18. Docker Platform
Docker Image
Docker Engine
Registry Service (Docker Hub or Docker Trusted Registry)
Cloud or server based storage and distribution service for images
Docker Container

Docker Hub provides a centralized resource for container image discovery,
distribution and change management, user and team collaboration, and workflow
automation

30. But about the OS

: Compatible

35. DockerFiles
They just create a Independent File system that is used for the
Process,Memory,Network.

36. Versions don't matter,just the application
Node Python OS Anything
Tofu NPM Github VIM

37. COPY .. Command is the magic
Just makes a file system in the Dockerfile by copying the content in the root
directory.

38. WORKDIR is the new way to create a new file system
Node
NPM
LIB
WORKDIR
SPECIFIED FOR THE
DOCKER
CONTAINER
ALL the file that was
copied from the
home directory
