Jenkins vs Rancher: What are the differences?
Key Differences between Jenkins and Rancher
Jenkins and Rancher are both widely used tools in the DevOps world, but they serve different purposes and have distinct features that set them apart from each other.
Architecture and Purpose: Jenkins is a popular open-source automation server primarily used for continuous integration and continuous delivery (CI/CD) workflows. It provides a powerful platform to automate the building, testing, and deployment of applications. Rancher, on the other hand, is a container management platform that simplifies the deployment and management of containers across various infrastructure. It offers a comprehensive set of features for container orchestration and management.
Scalability and Flexibility: Jenkins is highly scalable and can handle large-scale CI/CD pipelines with ease. It supports distributed builds and can be scaled horizontally by adding more Jenkins agents. Rancher, on the other hand, is designed to manage containerized applications and supports container orchestration frameworks like Kubernetes, making it more suitable for managing large-scale container deployments and offering more flexibility in terms of infrastructure choices.
User Interface and Ease of Use: Jenkins has a web-based user interface that allows users to configure jobs, view build history, and manage plugins. It provides a highly customizable and extensible platform, but the user interface can be overwhelming for beginners. Rancher, on the other hand, offers an intuitive and user-friendly web-based UI that simplifies the management of containers and provides a streamlined experience for users.
Plugin Ecosystem and Integrations: Jenkins has a vast plugin ecosystem that provides a wide range of integrations with various tools and technologies. It supports integrations with source control systems, build tools, test frameworks, and deployment platforms, making it highly versatile. Rancher, on the other hand, integrates well with container orchestrators like Kubernetes and provides a rich set of features for managing and monitoring containerized applications.
Security and Access Control: Jenkins provides basic security features such as user authentication and authorization. It also supports role-based access control (RBAC) and integrates with external security providers. Rancher, on the other hand, offers more advanced security features such as network segmentation and RBAC at multiple levels, making it more suitable for multi-tenant environments and production deployments.
Community Support and Documentation: Jenkins has a large and active community, with a vast amount of documentation, tutorials, and community-contributed plugins available. It has been around for a long time and has a well-established user base. Rancher also has a growing community and provides comprehensive documentation and support resources, but it may not be as mature as Jenkins in terms of community support and plugin availability.
In summary, Jenkins is an automation server focused on CI/CD workflows, while Rancher is a container management platform designed for container orchestration and management. Jenkins is highly scalable and flexible, with a wide range of plugins and integrations, while Rancher offers a user-friendly UI, advanced security features, and native support for container orchestrators like Kubernetes.
We are currently using Azure Pipelines for continous integration. Our applications are developed witn .NET framework. But when we look at the online Jenkins is the most widely used tool for continous integration. Can you please give me the advice which one is best to use for my case Azure pipeline or jenkins.
If your source code is on GitHub, also take a look at Github actions. https://github.com/features/actions
I'm open to anything. just want something that break less and doesn't need me to pay for it, and can be hosted on Docker. our scripting language is powershell core. so it's better to support it. also we are building dotnet core in our pipeline, so if they have anything related that helps with the CI would be nice.
Google cloud build can help you. It is hosted on cloud and also provide reasonable free quota.
I'm planning to setup complete CD-CD setup for spark and python application which we are going to deploy in aws lambda and EMR Cluster. Which tool would be best one to choose. Since my company is trying to adopt to concourse i would like to understand what are the lack of capabilities concourse have . Thanks in advance !
I would definetly recommend Concourse to you, as it is one of the most advanced modern methods of making CI/CD while Jenkins is an old monolithic dinosaur. Concourse itself is cloudnative and containerbased which helps you to build simple, high-performance and scalable CI/CD pipelines. In my opinion, the only lack of skills you have with Concourse is your own knowledge of how to build pipelines and automate things. Technincally there is no lack, i would even say you can extend it way more easily. But as a Con it is more easy to interact with Jenkins if you are only used to UIs. Concourse needs someone which is capable of using CLIs.
From a StackShare Community member: "Currently we use Travis CI and have optimized it as much as we can so our builds are fairly quick. Our boss is all about redundancy so we are looking for another solution to fall back on in case Travis goes down and/or jacks prices way up (they were recently acquired). Could someone recommend which CI we should go with and if they have time, an explanation of how they're different?"
We use CircleCI because of the better value it provides in its plans. I'm sure we could have used Travis just as easily but we found CircleCI's pricing to be more reasonable. In the two years since we signed up, the service has improved. CircleCI is always innovating and iterating on their platform. We have been very satisfied.
As the maintainer of the Karate DSL open-source project - I found Travis CI very easy to integrate into the GitHub workflow and it has been steady sailing for more than 2 years now ! It works well for Java / Apache Maven projects and we were able to configure it to use the latest Oracle JDK as per our needs. Thanks to the Travis CI team for this service to the open-source community !
I use Google Cloud Build because it's my first foray into the CICD world(loving it so far), and I wanted to work with something GCP native to avoid giving permissions to other SaaS tools like CircleCI and Travis CI.
I really like it because it's free for the first 120 minutes, and it's one of the few CICD tools that enterprises are open to using since it's contained within GCP.
One of the unique things is that it has the Kaniko cache, which speeds up builds by creating intermediate layers within the docker image vs. pushing the full thing from the start. Helpful when you're installing just a few additional dependencies.
Feel free to checkout an example: Cloudbuild Example
I use Travis CI because of various reasons - 1. Cloud based system so no dedicated server required, and you do not need to administrate it. 2. Easy YAML configuration. 3. Supports Major Programming Languages. 4. Support of build matrix 6. Supports AWS, Azure, Docker, Heroku, Google Cloud, Github Pages, PyPi and lot more. 7. Slack Notifications.
You are probably looking at another hosted solution: Jenkins is a good tool but it way too work intensive to be used as just a backup solution.
I have good experience with Circle-CI, Codeship, Drone.io and Travis (as well as problematic experiences with all of them), but my go-to tool is Gitlab CI: simple, powerful and if you have problems with their limitations or pricing, you can always install runners somewhere and use Gitlab just for scheduling and management. Even if you don't host your git repository at Gitlab, you can have Gitlab pull changes automatically from wherever you repo lives.
If you are considering Jenkins I would recommend at least checking out Buildkite. The agents are self-hosted (like Jenkins) but the interface is hosted for you. It meshes up some of the things I like about hosted services (pipeline definitions in YAML, managed interface and authentication) with things I like about Jenkins (local customizable agent images, secrets only on own instances, custom agent level scripts, sizing instances to your needs).
Within our deployment pipeline, we have a need to deploy to multiple customer environments, and manage secrets specifically in a way that integrates well with AWS, Kubernetes Secrets, Terraform and our pipelines ourselves.
Jenkins offered us the ability to choose one of a number of credentials/secrets management approaches, and models secrets as a more dynamic concept that GitHub Actions provided.
Additionally, we are operating Jenkins within our development Kubernetes cluster as a kind of system-wide orchestrator, allowing us to use Kubernetes pods as build agents, avoiding the ongoing direct costs associated with GitHub Actions minutes / per-user pricing. Obviously as a consequence we take on the indirect costs of maintain Jenkins itself, patching it, upgrading etc. However our experience with managing Jenkins via Kubernetes and declarative Jenkins configuration has led us to believe that this cost is small, particularly as the majority of actual building and testing is handled inside docker containers and Kubernetes, alleviating the need for less supported plugins that may make Jenkins administration more difficult.
Jenkins is a pretty flexible, complete tool. Especially I love the possibility to configure jobs as a code with Jenkins pipelines.
CircleCI is well suited for small projects where the main task is to run continuous integration as quickly as possible. Travis CI is recommended primarily for open-source projects that need to be tested in different environments.
And for something a bit larger I prefer to use Jenkins because it is possible to make serious system configuration thereby different plugins. In Jenkins, I can change almost anything. But if you want to start the CI chain as soon as possible, Jenkins may not be the right choice.
