JENKINS VS TEAMCITY UPGRADE

Don't upgrade your mission critical Jenkins instance until you've tried the new version somewhere else first. Upgrading Jenkins sometimes breaks functionality, especially with plugins. If you can solve the config generation problem, this makes setting up and deploying Jenkins much easier, and also makes it easier to keep all your stuff in source control. You may not have something like that, but there are open source tools which do similar things (generate configs using templates).

The instances are installed and configured automatically using an in-house deployment tool. In our case, we run a separate Jenkins 'Cron' instance for each environment. Having all these jobs on one Jenkins can become unwieldly, and manually configuring them gets to be a huge pain. If you have multiple environments (Dev, UAT, Prod), typically you have slightly different versions of a job running on each environment. If time to resolution is a concern, having a standby pre-configured somewhere is probably a good idea as well. Even if you can't get the original server back up, as long as you have your job configs it's trivial to get them setup somewhere else. So you better have good monitoring to catch outages immediately, as well as all your configurations saved in source control. Some of my favorites: Cron Column, Rebuild, NodeLabel Parameter, Log Parser, and Email-ext.Īdvanced scheduling/trigger support: The schedule syntax basically is cron, so you have the same flexbility there, but this is supplemented by Triggers, the REST API, and the Groovy/Java APIĬentral point of failure: Because all your jobs are kicked off by one server, if that box goes down and nobody notices, Big Trouble. I think this is really Jenkins 'killer' feature, since if Jenkins itself doesn't provide what you're looking for (often the case), more often than not there is a plugin that does. Jenkins plug-in ecosystem is very active and provides a host of additional functionality. Support teams especially appreciate having this central location for checking problems and re-running jobs. You get email alerts out of the box, a common dashboard for everything, a web interface for logs, and an easy way to setup additional nodes to run jobs on. If you are managing a large number of processes across dozens of servers and multiple environments, it makes many things easier. Take advantage of the numerous integrations and orbs already written for you.We've been using Jenkins as a cron drop in for a couple years now, and here are some pros and cons:

Steps, execution environments, and jobs can be templated, parameterized, shared, and reused across different projects and teams using CircleCI orbs. Dependencies and libraries can be installed ad-hoc in your job, and we offer dependency caching to speed up subsequent builds. See our integrations page for existing partnerships. Our config allows integration with any platform or cloud provider that has an API. FlexibilityĬircleCI is vendor and tool-agnostic. You can run one - or hundreds - of jobs concurrently without any hassle or overhead. Auto-Scaling ArchitectureĪll execution environments are dynamically created according to your config and terminated on completion of tasks.

It is easy to maintain and trivial to learn, and your CI/CD pipeline can be tracked and versioned like the rest of your source code. The majority of CircleCI’s configuration is done via YAML.

Throughout this process, consult the Configuration Reference for a list of all available configuration on the CircleCI platform. Next, optimize your jobs with advanced features to see how much faster your builds could run on the CircleCI platform. This would essentially migrate your Build Chain. Consult our Examples and Guides Overview for various examples in different languages and frameworks.Īfter finishing one job, setup your other jobs on CircleCI and then configure a workflow. For example, a Rails project may use a Ruby container image and run bundler commands. Once you understand the config, modify the executor and the individual steps to meet your needs.

This configuration demonstrates the simplicity of our YAML setup, and it showcases how to define both an execution environment and the steps to run within it. Quickly build and run a simple Hello World job in any repository. Read (or at least browse) this document to solidify conceptual differences.
