Jenkins tutorial
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.

One Example ofWhat 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.
