Jenkins is a tool that allows users to automate multi-step processes that involve dependencies across multiple servers. It can be used to continuously build, test, and deploy code by triggering jobs that integrate code, run tests, deploy updates, and more. Jenkins provides a web-based interface to configure and manage recurring jobs and can scale to include slave agents to perform tasks on other machines. It offers many plugins to support tasks like testing, deployment, and notifications.

Jenkins tutorial
- 3. The Big IDEA Get something done automatically (hands-free) that involves: Multiple Steps Steps have dependencies May have to execute multiple things on multiple servers
- 4. One Example of What You Can do with Jenkins At 3:21 on Sunday Get token from Vault using predefined authentication variables (inserted by OPS) Login to Google Cloud using that token Copy 2TB of data from HDFS Process that data using a Python program Copy output to Google Dataflow If it fails or takes more than 60 minutes, page on-call using Pagerduty plugin If it succeeds, send our team an email. Delete the token, because security does not allow tokens to live outside Vault. Keep detailed logs for 30 last runs. Keep other metadata like run-times, also.
- 5. Another Example Grab new version of code from git repo Integrate it with maven or some other tool Deploy it to 500 servers Do some automated testing Decided if this new version is good or not If automated testing fails, roll the whole thing back and page on-call
- 6. There are Other Comparable Tools
- 7. You Can Use Jenkins on AWS (if you don’t fee like managing your own)
- 9. Jenkins Architecture You can have many slaves Each slave can have labels Nothing except java is needed on slaves Just a jar file that the master pushes during agent installation
