ScalabilityJenkins is designed to be scalable and can be run on a single machine or as a distributed system.Ansible is designed to be lightweight and can be used to manage large numbers of servers and devices.
Deployment environmentsJenkins can be used to automate the build and deployment process for applications running in a variety of environments, including on-premises servers and cloud platforms.Ansible is primarily used to automate the deployment and management of infrastructure and applications in cloud environments, but can also be used to manage on-premises servers.
Learning curveJenkins has a more complex user interface and requires more setup and configuration, but it provides a wide range of features and plugins for managing build and test processes.Ansible has a relatively low learning curve and is easy to get started with due to its straightforward configuration syntax.
InterfaceJenkins provides a web-based interface for configuring and managing build jobs, as well as tools for integrating with version control systems and testing frameworks. The Jenkins interface is highly customizable and provides a range of options for configuring build pipelines, setting up build agents, and integrating with other tools and services. Jenkins also provides a command-line interface (CLI) for managing build jobs and other aspects of the Jenkins environment. Ansible provides a command-line interface (CLI) for running ad-hoc tasks and managing inventory, as well as a web-based interface called Ansible Tower for managing and scaling Ansible environments. Ansible Tower provides a range of features for managing and automating the deployment, configuration, and management of infrastructure and applications, including role-based access control, scheduling, and integration with other tools and services.

Ansible vs Jenkins: Which is better?

Jenkins is often regarded as a more effective solution for continuous integration (CI) and continuous delivery (CD) procedures. Jenkins has support for testing frameworks, code coverage tools, and static analysis tools, among other capabilities and plugins for creating, testing, and deploying software updates.

Jenkins, for example, may be set up to execute tests whenever code is submitted to a version control repository or on a regular basis. It may also be set to send test results to developers and generate reports on test coverage and other metrics. Jenkins also has a number of plugins for interacting with testing frameworks and tools such as JUnit and Selenium.

Meanwhile, Ansible is primarily a configuration management and orchestration tool used to automate infrastructure and application deployment, setup, and administration. Ansible may be used to automate testing, but it is not as extensive or specialized for this purpose as Jenkins.

Jenkins and Ansible can be used as part of a larger testing and deployment pipeline. Jenkins, for example, may be used to develop and test software changes, and Ansible to deploy such changes to production environments. Jenkins is the preferred solution for smaller jobs that need the use of many tools, such as build, testing, and code quality analysis.

Ansible is the ideal tool for complex infrastructures with too many servers. It is known for its efficient system of inventory management, which is great for managing systems. In summary, Jenkins is generally considered to be a better tool for testing software projects, while Ansible is better suited for automating the deployment, configuration, and management of infrastructure and applications. Both these tools can be used together as part of a larger testing and deployment pipeline.

Both tools boast great community support. However, Ansible is preferred if users are looking for support because the developer behind it, Redhat, backs it up. Both Jenkins and Ansible are popular tools in the software development and DevOps communities, but Jenkins has a larger user base and a longer history.

How to Integrate Ansible in Jenkins?

In the following section, we have described the steps to integrate Ansible in Jenkins using Apache Tomcat.

  • Step 1: Make a Jenkins job. Configure the SCM repo using the GitHub code
  • Step 2: Configure the build
  • Step 3: Make a roles directory inside the Jenkins workspace
  • Step 4: Make the Tomcat role within the Jenkins workspace location with the command given below:-

$ sudo ansible-galaxy init tomcat –offline

The main site.yml file is developed in the directory named /var/lib/Jenkins/workspace/<Jenkins-Job-Name>.

  • Step 5: Configure the post-build step of Jenkins to bring forth the Ansible playbook. You can call the site.yml file and save the job.
  • Step 6: Activate the build job and deploy the Tomcat URL to verify if the application is deployed correctly.


Jenkins and Ansible have been well-received amongst developers. These two automation technologies have simplified the efficient running of operations. However, when it comes to the matter of choice, you need to weigh out your options. Choose the tool that is best suited for your business needs.
