Jenkins vs Semaphore: What are the differences?
Introduction
Jenkins and Semaphore are both popular continuous integration/continuous deployment (CI/CD) tools used for automating software development processes. While they have similar goals, there are key differences between the two.
Architecture: Jenkins is a self-hosted, open-source platform that can be installed on a local server or cloud environment. It is highly customizable and can be extended with plugins. On the other hand, Semaphore is a cloud-based CI/CD platform, which means it is hosted entirely on the cloud and does not require any installation or maintenance.
Ease of Use: Jenkins, being highly customizable, comes with a steeper learning curve. It requires users to configure and manage the platform, set up servers, and handle updates. Semaphore, on the other hand, offers a user-friendly web interface and provides intuitive workflows, making it easier to set up and use for CI/CD processes.
Scalability: Jenkins is known for its scalability and can handle large-scale CI/CD processes. With its plugin ecosystem, it offers extensive capabilities to support complex configurations. Semaphore, while capable of handling small to medium-sized projects, may have limitations when it comes to scaling up to support large-scale enterprise applications.
Pricing Model: Jenkins is an open-source tool, which means it is free to use. However, the cost of hosting and maintaining the infrastructure needs to be considered. Semaphore, on the other hand, offers different pricing plans depending on the user's needs. It offers a free plan with limited resources, as well as paid plans with additional features and higher resource allocations.
Integration and Ecosystem: Jenkins has a vast ecosystem of plugins and integrations with popular tools and services. This allows for seamless integration with various development, testing, and deployment technologies. Semaphore, while it does offer integrations with commonly used tools, may have a more limited ecosystem compared to Jenkins.
Support and Documentation: Jenkins has a large community of users and contributors, resulting in extensive documentation, forums, and support resources available online. Semaphore also provides documentation and support channels, but the community and resources might be comparatively smaller, given its cloud-based nature.
In summary, Jenkins is a highly customizable, self-hosted CI/CD platform with a robust ecosystem, but it requires more effort in terms of maintenance and scalability. Semaphore, being a cloud-based platform, offers ease of use and scalability, but with a potentially more limited ecosystem and pricing considerations. Choose the tool that best aligns with your specific requirements and project needs.
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).
Github Actions allowed us to drop previous CI/CD technologies like Jenkins or AWS CodeBuild. The main advantages for us are: - The Infrastructure-as-Code approach of Github Actions enables us to keep CI/CD configurations next to the code. - Github as a single platform for repositories and CI/CD simplifies our stack and effort to manage it on the daily basis.
TVcloud Team <3 Github Actions
We replaced Jenkins with Github Actions for all our repositories hosted on Github. GA has two significant benefits for us compared to an external build tool: it's simpler, and it sits at eye level.
Its simplicity and smooth user experience makes it easier for all developers to adopt, giving them more autonomy.
Sitting at eye level means it's completely run and configured right alongside the code, so that it's easier to observe and adjust our builds as we go.
These two benefits have made "the build" less of a system engineer responsibility and more of a developer tool, giving developers more ownership from code to release.
Jenkins is a friend of mine. 😀
There are not much space for Jenkins competitors for now from my point of view. With declarative pipelines now in place, its super easy to maintain them and create new ones(altho I prefer scripted still). Self-hosted, free, huge community makes it the top choice so honestly for me it was an easy pick.
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.
