[Spring Boot & MSA] Deploy with Docker & EC2 Instances

✔ 깃허브 소스코드
✔ Udemy 강의

1) AWS EC2 인스턴스에 연결

키페어 소유자만이 접근할 수 있도록 권한 설정

chmod 400 photo-app-api-keypair.pem

EC2 연결

ssh -i "photo-app-api-keypair.pem" ec2-user@ec2-15-164-49-140.ap-northeast-2.compute.amazonaws.com

2) EC2 인스턴스에 Docker 설치

sudo yum install docker 
sudo service docker start
sudo usermod -a -G docker ec2-user

Note

• sudo usermod -a -G docker ec2-user 사용 후에 exit을 치고 다시 접속하면 sudo를 치면서 Docker를 사용하지 않아도 됩니다.

3) Run RabbitMQ Docker Container

RabbitMQ 실행

 docker run -d --name photoapp-rabbitmq -p 15672:15672 -p 5672:5672 -p 15671:15671 -p 5671:5671 -p 4369:4369 rabbitmq:3-management

Note

• 실행후 해당 포트번호들을 EC2 Security Group에 추가

4) Config Server Docker 이미지 배포

Dockerfile 생성

FROM openjdk:8-jdk-alpine
VOLUME /tmp
COPY UnlimitedJCEPolicyJDK8/* /usr/lib/jvm/java-1.8-openjdk/jre/lib/security/
COPY target/PhotoAppApiConfigServer-0.0.1-SNAPSHOT.jar ConfigServer.jar
ENTRYPOINT ["java", "-jar", "ConfigServer.jar"]

Docker image 생성

docker build --tag=config-server --force-rm=true .

생성한 Docker image 태그 추가

docker tag {image.id} dnjscksdn98/config-server

DockerHub로 push

docker push dnjscksdn98/config-server

5) Run Config Server Docker Container in EC2 Instance

RabbitMQ IP 주소 검색

docker inspect {rabbitmq.id}

Run Config Server from DockerHub

docker run -d -p 8012:8012 -e "spring.rabbitmq.host={ip.address}" dnjscksdn98/config-server

Note

• 실행후 해당 포트번호를 EC2 Security Group에 추가(with private ip)
• 테스트를 위해 자신의 IP 주소도 추가

6) Eureka Server Docker 이미지 배포

Dockerfile 생성

FROM openjdk:8-jdk-alpine
COPY target/PhotoAppDiscoveryService-0.0.1-SNAPSHOT.jar DiscoveryService.jar
ENTRYPOINT ["java", "-jar", "DiscoveryService.jar"]

Docker image 생성

docker build --tag=config-server --force-rm=true .

생성한 Docker image 태그 추가

docker tag {image.id} dnjscksdn98/config-server

DockerHub로 push

docker push dnjscksdn98/config-server

7) Run Eureka Server Docker Container in EC2 Instance

Run Eureka Server from DockerHub and override config server uri

 docker run -d -p 8010:8010 -e "spring.cloud.config.uri=http://{configServer.privateIP}:8012" dnjscksdn98/eureka-server

8) Zuul Api Gateway Server Docker 이미지 배포

Dockerfile 생성

FROM openjdk:8-jdk-alpine
VOLUME /tmp
COPY target/PhotoAppZuulApiGateway-0.0.1-SNAPSHOT.jar ZuulApiGateway.jar
ENTRYPOINT ["java", "-jar", "ZuulApiGateway.jar"]

Docker image 생성

docker build --tag=config-server --force-rm=true .

생성한 Docker image 태그 추가

docker tag {image.id} dnjscksdn98/config-server

DockerHub로 push

docker push dnjscksdn98/config-server

9) Run Zuul API Gateway Docker Container in EC2 Instance

 docker run -e "spring.cloud.config.uri=http://{configServer.privateIP}:8012" -e "spring.rabbitmq.host={RabbitMQ.IP}" -p 8011:8011 -d dnjscksdn98/zuul-api-gateway

10) Run Albums Docker Container in EC2 Instance

docker run -d \
> -e "spring.cloud.config.uri=http://{configServer.privateIP}:8012" \
> -e "logging.file=/api-logs/albums-ws.log" \
> -v /home/ec2-user/api-logs:/api-logs \
> -e "server.port=8989" \
> -p 8989:8989 \
> dnjscksdn98/albums-microservice

11) Run MySQL Docker Container in EC2 Instance

docker run -d \
> -p 3306:3306 \
> --name mysql-container \
> -e MYSQL_ROOT_PASSWORD=alex \
> -e MYSQL_DATABASE=photo_app \
> -e MYSQL_USER=alex \
> -e MYSQL_PASSWORD=alex \
> -v /var/lib/mysql:/var/lib/myslq \
> mysql:latest

• -v /var/lib/mysql:/var/lib/myslq
  • EC2 인스턴스나 Docker 컨테이너를 종료시켜도 데이터가 사라지는 것을 방지하기 위해 저장할 폴더 지정
