Ci Cd Jenkins Ansible: Jenkins-Ci Explained

Table of Contents

Jenkins-Ci is an open-source automation server initially released in 2011, designed to automate various development tasks such as testing, building, and deploying applications. It provides a user-friendly and customisable way for developers to create and monitor an automated workflow. This article covers the essential information about Jenkins-Ci and its usage within a Continuous Integration (CI) and Continuous Delivery (CD) environment, including setting up a Jenkins-Ci installation, configuring it and integrating it with automation tools such as Ansible.

What is Jenkins-Ci?

Jenkins-Ci is a continuous integration and delivery platform designed to provide developers and teams with a reliable way to monitor their software projects. It automates development tasks such as unit testing, building, and deployment, allowing developers to concentrate on writing code. Jenkins-Ci also enables teams to monitor their workflows so they can be released more quickly and accurately.

Jenkins-Ci is an open-source tool written in Java, and is freely available from the Jenkins-Ci website. All of its features, including the built-in orchestration engine and all of its plugins, are completely free to use. The Jenkins-Ci community is also very active and regularly provides support to users.

Jenkins-Ci is a powerful tool that can be used to automate the entire software development process. It can be used to create pipelines for continuous integration and delivery, as well as to monitor and manage the entire software development lifecycle. With Jenkins-Ci, developers can quickly and easily create and deploy applications, and teams can collaborate more effectively.

Benefits of Using Jenkins-Ci

Jenkins-Ci helps developers save time and money by automating tedious tasks such as setting up a development environment or manually running tests. It also helps teams collaborate more easily as everyone has access to the same CI tools and processes. With Jenkins-Ci in place, developers can spend less time managing their software pipeline and more time writing quality code.

In addition, Jenkins-Ci is highly configurable and can be integrated with other tools such as Ansible, allowing developers to fully automate their software pipelines. This makes it a powerful automation tool that can easily be deployed in any CI/CD environment.

Jenkins-Ci also provides a wide range of plugins that can be used to extend its functionality. These plugins can be used to add additional features such as code coverage, performance testing, and security scanning. This makes Jenkins-Ci a great choice for teams looking to streamline their software development process.

Understanding the Jenkins-Ci Workflow

The Jenkins-Ci workflow consists of three main steps: source control, building the software, and deploying the application. Each of these steps is automated using Jenkins-Ci plugins.

The first step is source control, which is implemented using plugins such as the Jenkins-Git plugin. This allows developers to commit code to the project’s code repository from inside the Jenkins-Ci interface itself. This makes it easier for developers to keep track of any changes made to the codebase.

The second step is building the software using a variety of plugins. The Jenkins-Maven plugin is popular for building Java projects, while the Jenkins-Gradle plugin is popular for building Android projects. These plugins help developers quickly create the final product by compiling source code into an executable binary.

The third step is deploying the application. This can be done with a range of plugins including the Jenkins-Tomcat plugin, which can deploy web applications to a Tomcat server, or the Jenkins-Kubernetes plugin, which can deploy applications to a Kubernetes cluster.

Jenkins-Ci also provides a range of other features such as automated testing, code coverage, and performance monitoring. These features help developers ensure that their applications are running smoothly and efficiently, and can help identify any potential issues before they become a problem.

Setting Up a Jenkins-Ci Environment

To get started with Jenkins-Ci, first you need to install it on your server. This can be done using the command line or with an automated tool such as Chef, Puppet or Ansible. Once installation is complete, you will need to configure your Jenkins-Ci server.

Most importantly, you will need to add the plugins you need for your particular project. For example, if you need to build a Java project you will need the Jenkins-Maven plugin, or if you need to deploy an application you will need the Jenkins-Tomcat plugin. You can search for plugins from within the Jenkins-Ci web interface, or download them directly from the Jenkins-Ci plugin repository.

Once all the plugins are installed, you can then configure your CI/CD environment. This means setting up build jobs and pipelines, configuring and scheduling builds, and integrating with source control systems such as Git.

It is also important to ensure that your Jenkins-Ci environment is secure. This means setting up authentication and authorization, as well as configuring security settings such as firewalls and SSL certificates. Additionally, you should regularly monitor your Jenkins-Ci environment to ensure that it is running smoothly and that all jobs are running as expected.

Integrating with Ansible for Automation

Ansible is an open source automation tool designed to help developers manage their software environment in an organised and consistent way. It can be used to automate common development tasks such as configuration management, application deployment, and orchestration.

By integrating with Ansible, developers can significantly reduce the amount of time needed to setup and configure their CI/CD environment. Automated tasks can be divided into playbooks that Ansible can execute on demand, greatly speeding up the development process.

Establishing Continuous Integration with Jenkins-Ci

Continuous Integration (CI) is an automated process designed to test, build and deploy software whenever new code is committed. It helps teams ensure software applications remain consistent across different development environments. To set up a CI process with Jenkins-Ci, developers will need to create build jobs with specific tasks such as running tests and deploying applications.

These jobs can then be tested using Jenkins’ built-in web interface or using third-party automation tools such as Selenium or CasperJS. Once the build job is configured correctly, it can be scheduled to run at regular intervals. This ensures that applications are tested frequently throughout development, helping teams quickly identify any potential bugs or security vulnerabilities.

Running Tests with Jenkins-Ci

Jenkins-Ci provides several ways to run tests, one of which is via its built-in test frameworks such as JUnit and TestNG. These frameworks are designed to easily integrate into any CI/CD flow so teams can quickly run unit tests after each deployment. Additionally, developers can choose to integrate third-party testing tools such as Selenium or CasperJS into the build job so they can quickly test browsers or web applications.

Deployment Strategies with Jenkins-Ci

Jenkins-Ci allows developers to set up deployment strategies according to their needs. Developers can choose from a variety of deployment strategies such as rolling deployments for gradual software launches or blue/green deployments for rapid software updates. These strategies can be implemented using plugins such as the Kubernetes plugin or the Tomcat plugin.

Troubleshooting Common Issues with Jenkins-Ci

When something goes wrong with a Jenkins-Ci job, it’s important to be able to quickly diagnose the problem and take corrective action. To facilitate this, Jenkins-Ci provides several debugging tools such as console logs which can help identify issues quickly. Additionally, Jenkins-Ci also supports remote debugging tools such as SSH so developers can remotely connect to their system and quickly troubleshoot problems.


Jenkins-Ci is an open source automation platform designed to help developers automate their software development process. It enables teams to quickly set up a CI/CD environment for their projects and automate tasks such as testing, building and deploying applications. Additionally, its excellent integration with other automation tools such as Ansible allow developers to easily maintain their CI/CD flow without needing to manually intervene.
