Quick sample for building microservice with Spring Boot + Kubernetes and debug remotely

This project will show you how to setup kubernetes cluster by kubeadm , deploy spring boot micro service, and how to debug your code

Setup Kubernetes Cluster

See Setup Kubernetes By Kubeadm

Preparation

• create cluster role
  kubectl create clusterrolebinding admin --clusterrole=cluster-admin --serviceaccount=default:default
• Init mongodb
  kubectl apply -f kubernetes/mongodb

How To Deploy

• build projects mvn clean install
• build docker images
  bash build.sh
• push docker images
  bash push.sh Please skip this step if you run locally
• deploy to cluster
  kubectl apply -f kubernetes/projects
• deploy ingress
  kubectl apply -f kubernetes/ingress.yaml
• configure host
  run kubectl cluster-info to get cluster_ip
  add host to /etc/hosts with: <cluster_ip> micro.info

How To Test

• Init Data:
  curl -d '{"id":1,"id":1,"name":"company name","address":"company address"}' -H 'Content-Type:application/json' shawn.info/organization/

  curl -d '{"organizationId":1,"id":1,"name":"department name"}' -H 'Content-Type:application/json' shawn.info/department/

  curl -d '{"organizationId":1,"departmentId":1,"id":1,"name":"employee"}' -H 'Content-Type:application/json' shawn.info/employee/ .

• check result:

  curl micro.info/employee/1 .

  curl micro.info/department/1 .

  curl micro.info/department/organization/1/with-employees

How To Debug With Telepresence

Install Telepresence

OS X

brew cask install osxfuse
brew install datawire/blackbird/telepresence

Ubuntu 16.04 or later

curl -s https://packagecloud.io/install/repositories/datawireio/telepresence/script.deb.sh | sudo bash
sudo apt install --no-install-recommends telepresence

for other OS, See More

Configure

• generate env.json
  telepresence --swap-deployment <service in k8s> --env-json service.env.json
• load env in IDEA
  you will need to install the Env File plugin. load the service.env.json generated above
• debug your code as usual
  Refer To: Using Telepresence with IntelliJ
