Jenkins vs Rancher: What are the differences?
Jenkins: An extendable open source continuous integration server. In a nutshell Jenkins CI is the leading open-source continuous integration server. Built with Java, it provides over 300 plugins to support building and testing virtually any project; Rancher: Open Source Platform for Running a Private Container Service. Rancher is an open source container management platform that includes full distributions of Kubernetes, Apache Mesos and Docker Swarm, and makes it simple to operate container clusters on any cloud or infrastructure platform.
Jenkins can be classified as a tool in the "Continuous Integration" category, while Rancher is grouped under "Container Tools".
Some of the features offered by Jenkins are:
- Easy installation
- Easy configuration
- Change set support
On the other hand, Rancher provides the following key features:
- Manage Hosts, Deploy Containers, Monitor Resources
- User Management & Collaboration
- Native Docker APIs & Tools
"Hosted internally", "Free open source" and "Great to build, deploy or launch anything async" are the key factors why developers consider Jenkins; whereas "Easy to use", "Open source and totally free" and "Multi-host docker-compose support" are the primary reasons why Rancher is favored.
Jenkins and Rancher are both open source tools. Jenkins with 13.2K GitHub stars and 5.43K forks on GitHub appears to be more popular than Rancher with 11.8K GitHub stars and 1.31K GitHub forks.
Instacart, Lyft, and Twitch are some of the popular companies that use Jenkins, whereas Rancher is used by Packet, Redox Engine, and VCCloud. Jenkins has a broader approval, being mentioned in 1753 company stacks & 1479 developers stacks; compared to Rancher, which is listed in 88 company stacks and 35 developer stacks.

- Consume too much unnecessary resource by just running rancher agent alone;
- Hard to recover from system failure
- Bad performance of load balancing (compare to dokcer swarm built-in LB or others).
All of our pull requests are automatically tested using Jenkins' integration with GitHub, and we provision and deploy our servers using Jenkins' interface. This is integrated with HipChat, immediately notifying us if anything goes wrong with a deployment.
Jenkins is our go-to devops automation tool. We use it for automated test builds, all the way up to server updates and deploys. It really helps maintain our homegrown continuous-integration suite. It even does our blue/green deploys.
- Continuous Deploy
- Dev stage: autodeploy by trigger push request from 'develop' branch of Gitlab
- Staging and production stages: Build and rollback quicly with Ansistrano playbook
- Sending messages of job results to Chatwork.
Currently serves as the location that our QA team builds various automated testing jobs.
At one point we were using it for builds, but we ended up migrating away from them to Code Pipelines.
The whole infrastructure is managed through Rancher. It provides a simple interface to all the underlying tools - Docker, HAProxy (automatically configures load balancer from the containers).
We use Jenkins to schedule our Browser and API Based regression and acceptance tests on a regular bases. We use additionally to Jenkins GitlabCI for unit and component testing.
Currently looking to move to Swarm or Kubernetes due to a few issues I have with Rancher.
Orchestration of containers for our environments. Remote deployment from Jenkins.
We use Rancher for container orchestration and automated deployment pipelines.
