.platform / nginx / conf.d 디렉토리에 proxy.conf 파일을 수정한다. 

# nginx의 기본 업로드 제한 1MB
# 제한 풀기 -> 0
client_max_body_size 0;

 

"Dockerfile"을 생성한다. 

FROM openjdk:8-jdk-alpine
COPY build/libs/*.jar app.jar
ENTRYPOINT ["java","-jar","/app.jar"]

 

"Dockerrun.aws.json"을 생성한다. 

{
  "AWSEBDockerrunVersion": "1",
  "Image": {
    "Name": "[도커 리포지토리 endpoint]", 여기 입력
    "Update": "true"
  },
  "Ports": [
    {
      "ContainerPort": 8080
    }
  ]
}

 

AWS IAM으로 가서 역할(role)로 간다. 

elastic beanstalk의 역할에 "AmazonEC2ContainerRegistryReadOnly"을 추가한다. 

build.gradle에 다음 코드를 추가한다. 

jar {
    enabled = false
}

application.properties와 EB의 configuration의 환경변수를 맞게 설정한다. 

 

EbHealthCheck클래스를 추가한다. 

 

@RestController
public class EbHealthCheck {

    // EB 헬스체크를 위한 코드
    @GetMapping( "/")
    public ResponseEntity<?> doHealthCheck() {
        return ResponseEntity.ok("HealthCheck OK");
    }
}

아래와 같은 설정을 해준다.
