Automation and Monitoring with Hubot
Automation and Monitoring with Hubot
For DevOps and Developers
About the Book
DISCLAIMER: The book was written in end of 2014 and has not been updated since. Hubot has evolved, and example code may no longer be valid. However, the book still contains plenty of generic techniques that can be applied to newer versions of Hubot, also Slackbot, and any other chatbot tech.
This book covers everything you need to start using Hubot in your organization - installation on Linux, production grade deployment and init.d scripts. You will understand how Hubot scripts work, how to deal with dependencies, how to install new scripts and adjust them to suit your needs.
You will also learn to write and debug your own scripts, ranging from simple ones with just a few lines of code, to advanced ones that integrate several systems together.
There is a whole chapter for those who use GitHub - Hubot can do many wonderful things using GitHub API and web hooks. The book will show you ways to automate your infrastructure tasks and deployments using Jenkins, ways to integrate with numerous systems and services.
This knowledge was extracted from real world use and compacted into a single book. You can use it as a cookbook and pick just the things you need, or you can read it cover to cover and learn everything you can about using Hubot to full extent.
