Backend of the ScholarX project

Setting up minikube cluster

Prerequisites

• Java
• Maven
• Docker
• Minikube

1. Install minikube (help?)
2. Fork and clone the repo

3. Configure app resources files

cd scholarx
vim app/src/main/resources/application.yml

paste the code

spring:
  jpa:
    properties:
      hibernate:
        dialect: org.hibernate.dialect.MySQL5InnoDBDialect
    hibernate:
      ddl-auto: update
  datasource:
    url: jdbc:mysql://${DATABASE_HOST}:${DATABASE_PORT}/${DATABASE_NAME}?allowPublicKeyRetrieval=true&useSSL=false&useUnicode=true&characterEncoding=UTF-8
    username: ${DATABASE_USER}
    password: ${DATABASE_PASSOWRD}
  jmx:
    unique-names: true
server:
  error:
    include-message: always

4. Configure auth-server resources files

vim auth-server/src/main/resources/application.yaml 

paste the code

spring:
  thymeleaf:
    cache: false
  security:
    oauth2:
      client:
        registration:
          linkedin:
            client-id: ${CLIENT_ID}
            client-secret: ${CLIENT_SECRET}
            client-authentication-method: post
            authorization-grant-type: authorization_code
            redirect-uri: "{baseUrl}/login/oauth2/code/{registrationId}"
            scope: r_liteprofile, r_emailaddress
            client-name: Linkedin
        provider:
          linkedin:
            authorization-uri: https://www.linkedin.com/oauth/v2/authorization
            token-uri: https://www.linkedin.com/oauth/v2/accessToken
            user-info-uri: https://api.linkedin.com/v2/me?projection=(id,localizedFirstName,localizedLastName,profilePicture(displayImage~:playableStreams))
            user-name-attribute: id
            email-address-uri: https://api.linkedin.com/v2/emailAddress?q=members&projection=(elements*(handle~))
  jpa:
    properties:
      hibernate:
        dialect: org.hibernate.dialect.MySQL5InnoDBDialect
    hibernate:
      ddl-auto: update
  datasource:
    url: jdbc:mysql://${DATABASE_HOST}:${DATABASE_PORT}/${DATABASE_NAME}?allowPublicKeyRetrieval=true&useSSL=false&useUnicode=true&characterEncoding=UTF-8
    username: ${DATABASE_USER}
    password: ${DATABASE_PASSWORD}
  jmx:
    unique-names: true

note: ask from a member in dev-team for ${CLIENT_ID} and ${CLIENT_SECRET}

press :wq to write and quit

5. Build jar files for both modules

cd app
mvn clean install
cd ../auth-server
mvn clean install
cd ../

6. Start minikube

minikube start

7. Change docker environment from local to minikube

eval $(minikube docker-env)

8. Build docker images for both modules

docker build -t scholarx:latest app/
docker build -t auth-server:latest auth-server/

6. Enable minikube ingress addon

minikube addons enable ingress

7. Set up the kuberntes cluster

cd kube-config
kubectl apply -f mysql-db-deployment.yaml
kubectl apply -f mysql-db-service.yaml
kubectl apply -f scholarx-app-deployment.yaml
kubectl apply -f scholarx-app-service.yaml
kubectl apply -f auth-server-deployment.yaml
kubectl apply -f auth-server-service.yaml
kubectl apply -f ingress.yaml

8. Access the application Now the auth-server is exposed and can be accessed through minikube-ip

• Find the minikube ip

minikube ip
