The Journey of a Microservice: From Source Code to a Full-Blown Kubernetes Deployment

Introduction

In this lecture, we’ll containerize and deploy a RESTful Go microservice to a Kubernetes cluster. We’ll also learn about some important building blocks of our cluster such as Deployments, Services, ConfigMaps, Secrets, Ingresses, and the like.

The Environment Variables

Here are the environment variables of interest that our builder script uses:

ECR_IMAGE_FIZZ_CRYPTO=fizz-crypto
ECR_TAG_FIZZ_CRYPTO=0.0.15

ECR Login Script

Here’s the login script I used in the video:

aws ecr get-login-password --region us-west-2 | \
docker login --username AWS --password-stdin \
