Continuous Delivery

While working on a continuous delivery pipeline to automate deployment to Google Container Engine (GKE), I found that getting kubectl to work is very complexandconvoluted, especially when it needs to be noninteractive. So I want to find out the easiest way to get kubectl working noninteractively.

Assuming that gcloud and kubectl are already installed but not necessarily setup, ONLY two commands are needed to get kubectl working noninteractively (verified with Google Cloud SDK 141.0.0 and kubectl 1.5.2)

In my previous posts, I demoed how to orchestrate Docker with Swarm and Kubernetes. They all assume the Docker image chenglong/simple-node is already there and ready to be deployed. But how to develop that image in the first place? How to streamline and automate the process of developing it on local machine, building and testing it on Continuous Integration (CI) server, and finally deploying to production?

This post introduces one possible Docker workflow.
