Why devops is important?

DevOps implementation is going through the roof with most of the largest software organizations around the world invested heavily in its implementation. The core values of devops is effectively based on the Agile Manifesto but with one slight change which moves the focus from creating a working software to one that is more interested in the end-to-end software service mechanism and delivery.

Ever Wondered Why We Use Containers In DevOps?

At some point we’ve all said the words, “But it works on my machine.” It usually happens during testing or when you’re trying to get a new project set up. Sometimes it happens when you pull down changes from an updated branch.

Every machine has different underlying states depending on the operating system, other installed programs, and permissions. Getting a project to run locally could take hours or even days because of weird system issues.

The worst part is that this can also happen in production. If the server is configured differently than what you’re running locally, your changes might not work as you expect and cause problems for users. There’s a way around all of these common issues using containers.

What is a container

A container is a piece of software that packages code and its dependencies so that the application can run in any computing environment. They basically create a little unit that you can put on any operating system and reliably and consistently run the application. You don’t have to worry about any of those underlying system issues creeping in later.

Although containers were already used in Linux for years, they became more popular in recent years. Most of the time when people are talking about containers, they’re referring to Docker containers. These containers are built from images that include all of the dependencies needed to run an application.

When you think of containers, virtual machines might also come to mind. They are very similar, but the big difference is that containers virtualize the operating system instead of the hardware. That’s what makes them so easy to run on all of the operating systems consistently.

What containers have to do with DevOps

Since we know how odd happenings occur when you move code from one computing environment to another, this is also a common issue with moving code to the different environments in our DevOps process. You don’t want to have to deal with system differences between staging and production. That would require more work than it should.

Once you have an artifact built, you should be able to use it in any environment from local to production. That’s the reason we use containers in DevOps. It’s also invaluable when you’re working with microservices. Docker containers used with something like Kubernetes will make it easier for you to handle larger systems with more moving pieces.

Jenkins Is Getting Old — It’s Time to Move On

By far, Jenkins is the most adopted tool for continuous integration, owning nearly 50% of the market share. As so many developers are using it, it has excellent community support, like no other Jenkins alternative. With that, it has more than 1,500 plugins available for continuous integration and delivery purposes.

We love and respect Jenkins. After all, it’s the first tool we encountered at the beginning of our automation careers. But as things are rapidly changing in the automation field, Jenkins is** left behind with his old approach**. Even though many developers and companies are using it, most of them aren’t happy with it. Having used it ourselves on previous projects, we quickly became frustrated by its lack of functionality, numerous maintenance issues, dependencies, and scaling problems.

We decided to investigate if other developers face the same problems and quickly saw the need to create a tool ourselves. We asked some developers at last year’s AWS Summit in Berlin about this. Most of them told us that they chose Jenkins because it’s free in the first place. However, many of them expressed interest in trying to use some other Jenkins alternative.

Job Cycle and on Demand Tools of Devops Programming Engineer

The dream of everyone is to earn a high salary, DevOps is one way to reach this dream. Anyone can learn DevOps and get placed with a large corporation. This article will help you to gain complete knowledge about what are the roles and responsibilities of a DevOps Engineer.

Introduction to DevOps

DevOps is a compound of Development and Operations. DevOps is the combination of practices, and processes that increase the organization’s ability to provide qualified applications to add value to the customer businesses. In simple terms, DevOps is a methodology in which operations and development engineers collaborate during the service lifecycle from design to development to production support.

Roles and Responsibility of DevOps Engineer:

There are two main parts to creating an application and maintaining it using DevOps, development and operation.

1. Development (Software developers build the application
2. and test it)
3. Operation (The application is deployed and maintained on a server)

How to Extend your DevOps Strategy For Success in the Cloud?

DevOps and Cloud computing are joined at the hip, now that fact is well appreciated by the organizations that engaged in SaaS cloud and developed applications in the Cloud. During the COVID crisis period, most of the organizations have started using cloud computing services and implementing a cloud-first strategy to establish their remote operations. Similarly, the extended DevOps strategy will make the development process more agile with automated test cases.

According to the survey in EMEA, IT decision-makers have observed a 129%* improvement in the overall software development process when performing DevOps on the Cloud. This success result was just 81% when practicing only DevOps and 67%* when leveraging Cloud without DevOps. Not only that, but the practice has also made the software predictability better, improve the customer experience as well as speed up software delivery 2.6* times faster.

3 Core Principle to fit DevOps Strategy

If you consider implementing DevOps in concert with the Cloud, then the

below core principle will guide you to utilize the strategy.

• It is indispensable to follow a continuous process, including all stages from Dev to deploy with the help of auto-provisioning resources of the target platform.
• The team always keeps an eye on major and minor application changes that can typically appear within a few hours of development to operation. However, the support of unlimited resource provisioning is needed at the stage of deployment.
• Cloud or hybrid configuration can associate this process, but you must confirm that configuration should support multiple cloud brands like Microsoft, AWS, Google, any public and private cloud models.

Guide to Remold Business with DevOps and Cloud

Companies are now re-inventing themselves to become better at sensing the next big thing their customers need and finding ways with the Cloud based DevOps to get ahead of the competition.

Integrating SonarQube with Jenkins

Welcome back to the second article in our #BacktoBasics series. As many of us already know, SonarQube is an open-source tool for continuous inspection of code quality. It performs static analysis of code, thus detecting bugs, code smells and security vulnerabilities. In addition, it also can report on the duplicate code, unit tests, code coverage and code complexities for multiple programming languages. Hence, in order to achieve Continuous Integration with fully automated code analysis, it is important to integrate SonarQube with CI tools such as Jenkins. Here, we are going to discuss integrating SonarQube with Jenkins to perform code analysis.

Running Jenkins and SonarQube on Docker

Enough on the introductions. Let’s jump into the configurations, shall we? First of all, let’s spin up Jenkins and SonarQube using Docker containers. Note that, we are going to use docker compose as it is an easy method to handle multiple services. Below is the content of the docker-compose.yml file which we are going to use.

docker-compose.yml file

version: '3'
services:
  sonarqube: 
    ports: 
      - '9000:9000' 
    volumes: 
      - 'E:\work\sonar\conf\:/opt/sonarqube/conf' 
      - 'E:\work\sonar\data\:/opt/sonarqube/data' 
      - 'E:\work\sonar\logs\:/opt/sonarqube/logs' 
      - 'E:\work\sonar\extensions\:/opt/sonarqube/extensions' 
    image: sonarqube
  jenkins:
    image: 'ravindranathbarathy/jenkins'
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - 'E:\work\jenkins_home\:/var/jenkins_home'  
    ports:
      - '8080:8080'
      - '5000:50000'
  jenkins-slave:
    container_name: jenkins-slave
    restart: always
    environment:
            - 'JENKINS_URL=http://jenkins:8080'
    image: kaviyakulothungan/jenkins-slave-node:v2
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - 'E:\work\jenkins_slave\:/home/jenkins'
    depends_on:
      - jenkins

docker-compose up is the command to run the docker-compose.yml file.

Configuring Jenkins for SonarQube Analysis

In order to run the SonarQube analysis in Jenkins, there are few things we have to take care before creating the Jenkins job. First of all, we need to install the**_ ‘_SonarQube Scanner” plugin. For this, let’s go to Jenkins -> Manage Jenkins -> Manage Plugins. There, navigate to “Available” view and look for the plugin “SonarQube Scanner”. Select the plugin and click on “Install without restart**” and wait for the plugin to be installed.

Installing SonarQube Scanner Plugin

Once the plugin is installed, we need to configure a few things in the Jenkins global configuration page.

For that, let’s click on Jenkins -> Manage Jenkins -> Configure System -> SonarQube Servers and fill in the required details.

SonarQube Server Configuration

Here,

• Name: Anything meaningful. Eg. sonarqube
• Server URL:
• Server Authentication Token: Refer below

To get the server authentication token, login to SonarQube and go to Administration -> Security -> Users and then click on Tokens. There, Enter a Token name and click on Generate and copy the token value and paste it in the Jenkins field and then click on “Done”.

Creating Authorization Token

Finally, save the Jenkins Global configurations by clicking on the “Save” icon.

There is one last configuration which has to be set up. In order to run SonarQube scan for our project, we need to install and configure the SonarQube scanner in our Jenkins. For that, let’s go to Manage Jenkins -> Global Tool Configuration -> SonarQube Scanner -> SonarQube Scanner installations. Enter any meaningful name under the Name field and select an appropriate method in which you want to install this tool in Jenkins. Here, we are going to select “Install automatically” option. Then, click on “Save”.

Creating and Configuring Jenkins Pipeline Job

Since we are all set with the global configurations, let’s now create a Jenkins Pipeline Job for a simple node.js application for which code analysis will be done by SonarQube.

For that, let’s click on “New Item” in Jenkins home page and enter the job name as “sonarqube_test_pipeline” and then select the “Pipeline” option and then click on “OK”.

Creating Jenkins Pipeline job

Now, inside the job configuration, let’s go to the Pipeline step and select Pipeline Script from SCM and then select Git and enter the Repository URL and then save the job.
