DevOps(Day-27) : Jenkins Introduction

 

  • Continuous Integration

  • Continuous Delivery/Deployment

  • Jenkins

    • Jenkins Architecture

To enter into Jenkins let's first understand what is CI/CD (Continuous Integration/Continuous Delivery or Deployment).

It is the process of automating the steps for developers by building and testing the code before merging it into the commit branch.

Developers push the code in small increments to Version Control System which is GitHub, i.e then build through some tools like Maven and then tested.

It is the process of releasing the final version of the code to the server environment may be it is in Production.

The basic difference between Continous Delivery and Continous Deployment is, In Continous Delivery, there is a need for manual intervention to push the final code into Production or a higher environment whereas in Continous Deployment the final code is deployed automatically through the pipeline setup.

For this setup of the CI/CD pipeline, we use the Jenkins tool.

The Jenkins project was started in 2004 by Kohsuke Kawaguchi. Jenkins is open-source software that helps in building, testing, and deploying, facilitating continuous integration and continuous delivery.

With the help of Jenkins, organizations can speed up the software development process through automation.

Jenkins follows Master-Slave architecture to manage distributed builds. In this architecture, the slave and master communicate through TCP/IP protocol.

Jenkins architecture has two components:

  • Jenkins Master server

  • Jenkins Slave server

DevOps(Day-97): Meta-Arguments in Terraform

Image
  TABLE OF CONTENTS Write about meta-arguments and their use in Terraform. Task-01: Meta-Arguments HandsOn Count for-each When you define a resource block in Terraform, by default, this specifies one resource that will be created. To manage several of the same resources, you can use either count or for_each, which removes the need to write a separate block of code for each one. Using these options reduces overhead and makes your code neater. count is what is known as a ‘meta-argument’ defined by the Terraform language. Meta-arguments help achieve certain requirements within the resource block. Write about meta-arguments and their use in Terraform. Meta-arguments in Terraform refer to a set of special arguments that can be used to define how a particular resource or module behaves within a Terraform configuration. These arguments provide additional configuration options and enable fine-grained control over the behaviour of resources or modules. Meta-arguments are prefixed with the...

DevOps(Day-95): Auto Scaling with Terraform

Image
  TABLE OF CONTENTS Understanding Scaling Pre-requisites Task 1: Create an Auto Scaling Group Task 2: Test Scaling Yesterday, we learned how to AWS S3 Bucket with Terraform. Today, we will see how to scale our infrastructure with Terraform. Understanding Scaling Scaling is the process of adding or removing resources to match the changing demands of your application. As your application grows, you will need to add more resources to handle the increased load. And as the load decreases, you can remove the extra resources to save costs. Terraform makes it easy to scale your infrastructure by providing a declarative way to define your resources. You can define the number of resources you need and Terraform will automatically create or destroy the resources as needed. Pre-requisites Create a  terraform.tf  file declaring the providers to be installed in the system according to the resources required. Create a  provider.tf  file to declare the region. Create a  vp...

DevOps (Day-1) Introduction

Image
  TABLE OF CONTENTS Infrastructure Automation Why DevOps is Important? What is DevOps? As the name indicates:- Dev + Ops = Development + Operations. Development i) Backend Developers ii) Front-end Developers iii) QA Operations i) System admins ii) Network admins iii) Database admins The practice of operations and development engineers participating together in the entire service lifecycle through a pipeline from design through the development process to production support. This process is known as DevOps. This is a process of automating the whole infrastructure. Now here comes a query, what are we automating? We are automating the whole team's work from the code-building stage to code deployment. Scenario 1:- In a company, there is a project in which developers are writing the code and deploying it to the QA environment frequently for each sprint. This code is then tested by the testing team. Suppose there is a situation of mishap happens where the testing team used the older code ...
