What is DevOps?
DevOps is a software development approach which involves Continuous Development, Continuous testing,
Continuous Integration, Continuous Deployment and Continuous Monitoring throughout its development
lifecycle.

CI CD Pipeline

CI CD Pipeline
what is then the CI.
Since there are various developers say just take an example of a team which has five developers
and they are building a website which you can say is a shopping website.
so, the shopping website can have various avenues like one of them is the landing page where you show all the
products.
there can be another page which shows the user details and the past orders and things like that.
Another page can be the shopping cart which so whatever products the person has added to the cart.
Another page which is the “checkout page” where the person will pay and then make the purchase.
so, there are various avenues in a software.
These can be called as features of the software.
So, when you have multiple features, then you have to combine those features and merge them into a single version
control system where you merge the various feature branches of the code and make a single pool of code which can
be now comprising all the features from various branches committed by the developers and then you can build it as a
product and move on to testing.Now when you merge the code and you build the code to get a single unit saw of the
software.That phase is false integration.

Integration means putting all the code together, so we are putting together code from of the contributing developers
and then we are merging them and building it as a whole.
So that phase is called the continuous integration phase.
Why do we call it continuous because as I said in DevOps we use various tools to automate the pipeline.
Okay in contrast to the traditional practices what a traditional software company does manually people write the code
and manually put it somewhere then the manually merge it and the manual abilities in build commands and then a
tester manually tests it and then it manually gets deployed in a server by a system admin and then again there is a
series of sanity test manually done again by a QA and then it manually is deployed to the production what do you see
here in every phase there is a manually done thing right so that is how things are done in traditional way.
In DevOps we transform this to do everything in an automatic manner so as soon as a person commits the code from
the repository, it automatically moves and merges itself with the other codes which are present which are committed
at the same time and then it triggers off a build reaction which will build or compile the code and then it triggers the
test.
Then it triggers the deploy auto test and so on.
so the entire thing is triggered step by step automatically so that is what we are going to achieve.
you're going to create an automated pipeline so why is it known as continuous integration as I said this version control
and build phase are called the integration phase now since this is completely automated it happens continuously like

Use-Case

CHALLENGES
✓ Accelerate delivery of business applications while
maintaining the highest quality and security
standards.
SOLUTION
✓ Used CloudBees Jenkins Platform to provide a
stable, scalable CI infrastructure, automate
repeatable build processes and manage CD
pipelines from commit to deployment.
RESULT
✓ 90% of pipeline automated
✓ Their Deployment frequency increased 1,300%
✓ Developers/Engineers focused on application
development, not infrastructure
✓ Quality and Security ensured through repeatable
processes

Jenkins – The Ultimate CI Tool
Jenkins is an open source automation tool written in
Java with plugins built for Continuous Integration
purpose. Plugins allows integration of various DevOps
stages.

What is Docker?
Docker

Project Code
Docker Image
Docker Container
Virtual Machine
Docker
Hub
Production
Server
Staging Server
Container
Container
✓ Docker file builds a Docker image and that image contains all the project's code
✓ You can run that image to create as many docker containers as you want
✓ Then this Image can be uploaded on Docker hub, from Docker hub any one can pull the
image and build a container
