This document discusses containerization and Docker. It explains that containers package up code and dependencies to run reliably across environments using less space than virtual machines. With Docker, the same containerized images can be used for development, staging, and production environments, simplifying deployment. Docker allows applications to be built, shipped, and run anywhere while maintaining isolation and being lightweight, portable, and secure.

2. “The only
constant is
Change”

3. “It is not the
Strongest of the
species that
survives but the one
most adaptable to
change”

4. Roadmap

5. Virtual Machine
• A virtual machine is a
software computer that,
like a physical
computer, runs an
operating system and
applications.

6. Containerization
• A container is a standard
unit of software that
packages up code and all
its dependencies so the
application runs quickly
and reliably from one
computing environment
to another.

7. Docker vs VM
• Docker runs on
exactly the same host
and sharing its kernel
with their host,
• No hypervisor

8. Why?
• Setup DEV
server
• Setup apps and
libs
• Test
• Setup
STAGING
server
• Setup apps and
libs
• Test
• Setup
PRODUCTION
server
• Setup apps and
libs
• Test

9. With Container?
DEV
• Setup Images
• Setup apps and
libs
• Test
STAGING
• Test
PRODUCTION
• Test

10. With Container?
The same image will be used on each environment

11. Lifecycle
build ship test

12. Docker
• Docker is an open
platform for developers
and sysadmins to build,
ship, and run
distributed applications,
whether on laptops,
data center VMs, or the
cloud.

13. Docker Architecture
• Client
• Host
• Registry

14. Why Docker?
• Application run in
isolation
• Occupies less space
• Lightweight
• Secure
• Portable
• Short bootime

15. How?
• Docker file
• Docker image
• Run / Push to Registry

16. How?

17. Benefit?
• No external dependencies
• Easily ships
• Data can be shared and reused
• Os kernel sharing
