build server 부터 배포까지 - 5. GKE Spring Redis 배포 - Local, CI Server, Deploy Server에서 Redis와 연동

이번엔 로그인 기능에서 사용하는 토큰을 올리기 위해 redis를 올려보고자 한다.

 

 

1. Local

/application.properties

spring.redis.host=127.0.0.1 spring.redis.port=6379

이걸 추가한다.

 

/local/docker-compose.yml

version: "3"

services:
    mysql:
        image: mysql:5.6
        environment:
            MYSQL_DATABASE: bizschema
            MYSQL_ROOT_PASSWORD: rootpw
            MYSQL_USER: devroot
            MYSQL_PASSWORD: devpw
            LANG: C.UTF-8
        volumes:
            - local-mysqlvol:/var/lib/mysql
        ports:
            - 3306:3306
        command:  --character-set-server=utf8mb4 --collation-server=utf8mb4_general_ci
        container_name: local-mysql
    
    redis:
        image: redis:alpine
        hostname: redis-local
        ports:
            - 6379:6379
        container_name: local-redis
        

volumes:
    local-mysqlvol:

 

항상 그랬듯 redis 이미지를 당겨온다.

 

 

2. CI Server

ci server에서도 마찬가지다. 다만 spring과 연동이 되어야 하므로 network를 추가하자.

 

/ci-server/docker-compose.yml

version: "3"

services:
    jenkins:
        container_name: jenkins-compose
        image: jenkins/jenkins:lts
        user: root       
        ports:
         - "8081:8080" 
        volumes:
         - /var/run/docker.sock:/var/run/docker.sock
         - /usr/bin/docker:/usr/bin/docker
         - jenkins_data:/var/jenkins_home
        networks:
         - backend-network

    sonarqube:
        image: sonarqube:lts
        container_name: sonarqube
        ports:
         - "9000:9000"
        volumes:
         - sonarqube_conf:/opt/sonarqube/conf
         - sonarqube_data:/opt/sonarqube/data
         - sonarqube_extensions:/opt/sonarqube/extensions
         - sonarqube_logs:/opt/sonarqube/logs

    mysql:
        image: mysql:5.6
        container_name: ci-mysql
        environment: 
            MYSQL_DATABASE: bizschema
            MYSQL_ROOT_PASSWORD: rootpw
            MYSQL_USER: devroot
            MYSQL_PASSWORD: devpw
            LANG: C.UTF-8
        ports:
         - "3306:3306"
        command:  --character-set-server=utf8mb4 --collation-server=utf8mb4_general_ci
        volumes:
         - ciserver-mysqlvol:/var/lib/mysql
        networks:
         - backend-network

    redis:
        image: redis:alpine
        hostname: redis-local
        ports:
            - 6379:6379
        container_name: local-redis
        networks:
         - backend-network
        
        
volumes:
    ciserver-do:
    jenkins_data:
    sonarqube_conf:
    sonarqube_data:
    sonarqube_extensions:
    sonarqube_logs:

networks:
    backend-network:

 

 

3. Deploy Server

/deploy/redis.yml

apiVersion: v1
kind: Service
metadata:
  name: redis
  labels:
    app: redis
spec:
  type: LoadBalancer
  ports:
    - port: 6379
      targetPort: 6379
  selector:
    app: redis

---
apiVersion: apps/v1
kind: Deployment
metadata:
  name: redis
  labels:
    app: redis
spec:
  replicas: 1
  selector:
    matchLabels:
      app: redis
  template:
    metadata:
      labels:
        app: redis
    spec:
      containers:
        - name: redis
          image: redis:alpine
          ports:
            - containerPort: 6379
          env:
            - name: ALLOW_EMPTY_PASSWORD
              value: "yes"
            #- name: REDIS_PASSWORD
            #  value: your-password

만약 redis 비밀번호를 쓰고 싶으면 위에서 주석처리 되어 있는 redis_password를 설정해주면 된다. 이후 이걸 apply해서 redis의 service port를 받아온다.

 

 

/deploy/spring.yml

apiVersion: apps/v1
kind: Deployment
metadata: # deployment의 metadata
  name: spring-board-deploy
spec: # deployment의 spec
  replicas: 1
  selector:
    matchLabels:
      app: spring
      tier: backend
  strategy:
    type: RollingUpdate
    rollingUpdate:
      maxSurge: 2
      maxUnavailable: 2
  template: # 다음 줄부터는 각각 pod의 설정
    metadata:
      labels: # 각 pod들의 metadata
        app: spring
        tier: backend
    spec: # pod의 spec
      containers:
        - name: echo
          image: gcr.io/temporal-fx-321902/bizkicks-backend:0.0.6.2
          ports:  # 
            - containerPort: 8080
          env:
            - name: SPRING_DATASOURCE_USERNAME
              valueFrom:
                secretKeyRef:
                  name: userinfo
                  key: username
            - name: SPRING_DATASOURCE_PASSWORD
              valueFrom:
                secretKeyRef:
                  name: userinfo
                  key: userpw
            - name: SPRING_DATASOURCE_URL
              valueFrom:
                secretKeyRef:
                  name: dbinfo
                  key: url
            - name: SPRING_REDIS_HOST
              valueFrom:
                secretKeyRef:
                  name: reidsinfo
                  key: host
            - name : SPRING_REDIS_PORT
              valueFrom:
                secretKeyRef:
                  name: reidsinfo
                  key: port


---

apiVersion: v1
kind: Service
metadata: # Service의 metadata
  name: spring-board-service
spec:
  type: LoadBalancer
  ports:
    - port: 8080  # Service가 생성할 Port
      targetPort: 8080  # Service가 접근할 pod의 port
  selector: # Service가 접근할 pod의 label 조건
    app: spring
    tier: backend

SPRING_REDIS_PORT, SPRING_REDIS_HOST 2개에 값을 채워넣으면 완성!
