How to Implement ChatOps in AWS EKS with Hubot, Jenkins, and Slack

Brief Overview

ChatOps has been around for a decade but let’s admit that it is still a really awesome branch of DevOps. It is collaboration and communication-driven which lies at the very heart of DevOps. Hubot is your friendly-neighborhood robot that shall help us implement ChatOps.

Today, we are going to have a step-by-step development of a Hubot application. We will deploy it in a Kubernetes Cluster, integrate it with Jenkins and Slack, and then test a pipeline deployment by sending a chat. Fasten your seatbelts, this is going to be cool!
