Intro

This project shows an approach of having distributed OAuth2 authentication with API Gateway in Kubernetes environment

It consists of 3 components:

  • agw - API gateway component (AGW) - spring boot application leveraging on spring-cloud-gateway
  • portal - frontend React app serving as a client application of the system
  • users - simple BE API service

Other important directories:

  • k8s - contains systemwise kubernetes configuration

Minikube

Start minikube

npm run start

Check minikube host ip

This IP should be used to reach host services e.g. Keycloak running as a docker container in host machine. You can see it in msagw-oauth ConfigMap (oauth-cm.yaml).

minikube ssh
ping host.minikube.internal

Change docker context

Images to be deployed in minikube must be build in minikube docker context

from local to minikube

eval $(minikube docker-env)

from minikube to local

eval $(minikube docker-env -u)

Building the system

Minikube must be up and running and docker context in the shell must be set to minikube see

NOTICE: Before deploying any component to minikube remember to apply the files under k8s (e.g. by running npm run k8s) directory. It contains config-maps required for services to start properly.

Build AGW

build:agw

Build portal

build:portal

Make sure npm dependencies are installed first.

Build users service

build:users
