Welcome to the OpsMx’s Tech Talk series about quick insight into Spinnaker. In this edition we will explain how to build your first Continuous Delivery pipeline that deploys to a Kubernetes cluster. 

Here is a short video for the topic:

What is a pipeline in Spinnaker?

Pipelines are a way of managing deployments in a consistent, repeatable, and safe way. The pipeline is a sequence of stages provided by Spinnaker ranging from functions that manipulate infrastructure – like deploy, resize or disable, as well as a utility scaffolding function like manual judgment or run Jenkins job. These together precisely define your runbook for managing your deployments.

Prerequisites

  1. Have a working Kubernetes cluster
  2. Have the opensource Spinnaker installed with all other services
