Jenkins vs Kubernetes: Compare DevOps tools. Which is Better?

What is Kubernetes?

Kubernetes is an open-source CMS where ‘C’ stands for Container. Google created it. Kubernetes is used to handle a containerized program in any categories of physical, virtual, or cloud environments.

It is a very flexible container tool to even provide for the most complex applications. The software runs on clusters of millions of independent servers. Kubernetes also permits anyone with legit credentials to manage the containerized software.

Features of Kubernetes

  • Service location and load balancing: Kubernetes can find and allots the containers with IP addresses with a unique DNS name, which the DevOps engineer can use for load balancing.

  • Planning & Placement: Placement of the containers in the cluster is a critical attribute that makes the decision based on the types of resources it requires and how long.

  • Auto Scaling: Auto-scaling directly depends on CPU utilization. The vertical scaling of programs is automatically triggered using the CLI.

  • Self Repair: Self-repair is a special characteristic of the Kubernetes that will reboot the whole container when it fails to work. If the node stops working, then containers are restored and are reassigned to the other Nodes. You can control the containers yourself if they don’t respond during the health checks.

  • Storage Orchestration: The storage orchestration is the feature of Kubernetes that allows the client to scale the network storage system and localize it.

  • Batch execution: Kubernetes manages both batches as well as CI workloads along with restoring containers that don’t operate.

  • Configuration Management and Secrets: Classification and configuration are significant for Kubernetes. The information stored under a module called Secrets in Kubernetes. These Secrets are utilized while configuring the software without having to reestablish the image.

What is Jenkins?

Jenkins is a free DevOps automation tool written in Java programming language. It has many plugins that are used for Continuous Integration. Jenkins is used to developing and testing your software projects and applications. Thereby making it more straightforward for programmers and coders to merge the project’s changes.

Thus it makes it simple for end-users to get a new build. It also allows the user to continuously deliver your software by integrating with many testing & deployment of technologies.

With Jenkins, companies can stimulate the software development process through automation. Jenkins can enhance the development life-cycle processes of all kinds, including build, document, test, package, stage, deploy, static analysis, and much more.

Features of Jenkins

  • Easy Installation: Jenkins is a platform-agnostic, independent Java-based program. It is ready to be deployed within Windows OS, Mac OS, and Unix-like operating systems.

  • Easy Configuration: Jenkins has an easy configuration system using its web-based interface, featuring fault checks and an in-built Ask Help feature.

  • Available Plugins: There are many plugins available in the Update Center, integrating with every CI/CD toolchain tool.

  • Extensible: Jenkins is extendable through the plugin architecture, giving many endless possibilities for what it is capable of.

  • Easy Distribution: Jenkins can distribute tasks across several machines for faster development, testing, and support across many platforms.

  • Free Open Source: Jenkins is a free and open-source DevOps automation tool that is backed by robust community support.

Difference between Kubernetes and Jenkins

Kubernetes Jenkins

Kubernetes provides auto-scaling

Jenkins supports auto-scaling with the help of kubernetes

Kubernetes supports limits to 5000 nodes.

The number of Jenkins jobs/nodes relies on what is set as the limit in the number of master and slaves. It is variable and has no fixed limit.

Kubernetes is not customizable

Jenkins is not innately customizable, but one can customize Jenkins with the help of plugins

Kubernetes is container-orchestration system for automating computer applications with external help of CI/CD.

Jenkins is CI/CD model that can run/build/test the application.

Kubernetes is system for automating deployment, scaling and management.

Jenkins is automated software testing tool for your app.

One of the prominent use case of kubernetes is to deploy CI/CD pipelines that will track a code version of control system

Jenkins provides an easy UI/UX for the end-user to create and manage many CI/CD pipelines using its plugins.

Which is Better?

Jenkins and Kubernetes are intended for different applications, so the right choice will depend on a development team’s particular needs. There’s nothing stopping a developer from using Jenkins and Kubernetes together; in some cases, these tools may even complement each other, leading to a more robust CI/CD pipeline.

Jenkins is a great option for teams that need only an automation solution to help them implement continuous integration and deployment. The tool’s popularity and availability of plugins make it an excellent option.

Kubernetes is a popular orchestration tool for developers that need to deploy, manage and configure containers. The learning curve may present challenges, but its flexibility and feature set can provide significant value for various project types.

Jenkins is an automation tool that helps developers implement CI/CD, which can improve code quality and accelerate software development. Jenkins’ quick time to market can help developers ensure code changes are deployed in a timely manner.

By contrast, Kubernetes is a container orchestration tool. Kubernetes will be most valuable to developers who need to orchestrate many containers at the same time. The software can shift on-premises apps to the cloud and manage machine learning workflows. Kubernetes’ container healing and batch execution will make it easier for developers to manage project containers, even as the project grows.

However, Kubernetes and Jenkins may both be invaluable for cloud-native CI/CD. Developers working on these projects may even use the two tools together to streamline code testing, monitoring and deployment.
