Concepts

  • Choice better architecture what you expect based on k8s
  • Help understanding k8s resources based on yaml
  • Test automation on Github Actions for free
  • Expand test automation - unit, end-to-end, performance, recovery, security
  • Keep observability for monitoring services
  • Improve application quality using public CI services that following Github

Features

  • All docker components run on k8s
  • All application written by Java mostly Quarkus
  • k8s resources written by yaml, try not to use helm, operator
  • Use only public software, not commercial
  • Use Github Actions for build, test, release

Requirements

Installed CLI commands.

  • 💻 docker
  • 💻 kubectl
  • 💻 minikube

Run on Minikube

minikube config set cpus 6
minikube config set disk-size 80g
minikube start
minikube addons enable ingress
kubectl delete -A ValidatingWebhookConfiguration ingress-nginx-admission

eval $(minikube docker-env)

Windows
