1. 개요

Spring Boot Admin 은 Spring Boot 어플리케이션의 admin interface를 제공하는 UI 프레임워크이다. 각 서비스의 Spring Actuator Endpoints의 정보를 읽어와 Dashboard를 제공한다.

제공하는 기능

Health Status
Application 상세 정보
- JVM & memory metrics
- Datasource metrics
- Cache metrics 등
빌드 정보
Spring Boot Actuator 제공 정보
Hystrix stream 정보 등

2. 구성방법

SBA 1.5.x 구성

a. Server-side 구성 (1.5.x)

Spring boot project 생성

pom.xml dependency 추가

   <dependency>
     <groupId>org.springframework.cloud</groupId>
     <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
   </dependency>
   ...
 </dependencies>

application.yml - eureka 설정 추가

server:
 port: 8080
eureka:
 instance:
#    leaseRenewalIntervalInSeconds: 10
 client:
#    registryFetchIntervalSeconds: 5
   serviceUrl:
     defaultZone: ${EUREKA_SERVER_URL:http://localhost}:${EUREKA_SERVER_PORT:8761}/eureka/

@EnableAdminServer Annotation 추가

 @SpringBootApplication
 @EnableDiscoveryClient
 @Configuration
 @EnableAutoConfiguration
 @EnableAdminServer
 public class CoeAdminApplication {
 s    public static void main(String[] args) {
         SpringApplication.run(CoeAdminApplication.class, args);
     }
 }

b. Client-side 구성 with Eureka Client (1.5.x)

각 마이크로서비스가 Eureka Client로 구성되어 있는 경우, Actuator 정보만 추가하여 Admin Server에 자동 등록하고 사용할 수 있다.

Eureka 는 필수가 아니며, Spring Boot Admin Client 를 통해 구성 가능하다.

Eureka 는 필수가 아니며, Spring Boot Admin Client 를 통해 구성 가능하다.

Spring boot project 생성

pom.xml dependency 추가

   <dependency>

     <artifactId>spring-boot-starter-actuator</artifactId>
   </dependency>
   <dependency>
     <groupId>org.springframework.boot</groupId>

   eureka:
     client:
   serviceUrl:
     defaultZone: ${EUREKA_SERVER_URL:http://localhost}:${EUREKA_SERVER_PORT:8761}/eureka/

Spring boot 2.x 버전의 경우 default actuator endpoint는 health, info뿐이므로 명시적으로 열어줘야 함("*")

Eureka Discovery Annotation 추가, actuator access security 설정 추가

@SpringBootApplication
@EnableDiscoveryClient
@Configuration
@EnableAutoConfiguration
public class CoeZuulApplication {

 public static void main(String[] args) {
     SpringApplication.run(CoeZuulApplication.class, args);
 }

     @Override
     protected void configure(HttpSecurity http) throws Exception {
         http.authorizeRequests().anyRequest().permitAll()
                 .and().csrf().disable();
     }
 }
}

1.5.x Server 설정 추가

pom.xml dependency 추가

<dependency>

 <artifactId>spring-boot-admin-server-ui-login</artifactId>
</dependency>
<dependency>

 <artifactId>spring-boot-starter-security</artifactId>
</dependency>

application.yml 인증정보 추가

security:
 user:
   name: "user"
   password: "user"

SecurityConfig 설정 코드 추가

@Configuration
public static class SecurityConfig extends WebSecurityConfigurerAdapter {
 @Override
 protected void configure(HttpSecurity http) throws Exception {
   // Page with login form is served as /login.html and does a POST on /login
   http.formLogin().loginPage("/login.html").loginProcessingUrl("/login").permitAll();
   // The UI does a POST on /logout on logout
   http.logout().logoutUrl("/logout");
   // The ui currently doesn't support csrf
   http.csrf().disable();

   // Requests for the login page and the static assets are allowed
   http.authorizeRequests()
       .antMatchers("/login.html", "/**/*.css", "/img/**", "/third-party/**")
       .permitAll();
   // ... and any other request needs to be authorized
   http.authorizeRequests().antMatchers("/**").authenticated();

   // Enable so that the clients can authenticate via HTTP basic for registering
   http.httpBasic();
 }
}

2.0.x Server 설정 추가

pom.xml dependency 추가

<dependency>
 <groupId>org.springframework.boot</groupId>
 <artifactId>spring-boot-starter-security</artifactId>
</dependency>
<dependency>
 <groupId>org.springframework.boot</groupId>
 <artifactId>spring-boot-starter-web</artifactId>
</dependency>

application.yml 인증정보 추가

spring:
 security:
   user:
     name: "user"
     password: "user"
eureka:
instance:
 metadata-map:
   user.name: ${spring.security.user.name}
   user.password: ${spring.security.user.password}

eureka.instance.metadataMap.user.name/password

Registration 단계에서 SBA에 아래와 같은 형식으로 전달되어, SBA에서 해당 서비스의 actuator endpoint에 접근할 때 사용한다. (각 Client Service에서 Security가 필요한 경우 1,2단계를 동일하게 적용)

{
"registration": {
   "name": "FOO-SERVICE",
   "managementUrl": "http://localhost:8080/actuator",
   "healthUrl": "http://localhost:8080/actuator/health",
   "serviceUrl": "http://localhost:8080/",
   "source": "discovery",
   "metadata": {
       "user.name": "user",
       "management.port": "8080",
       "jmx.port": "52698",
       "user.password": "******"
       }
   }
}

SecurityConfig 설정 코드 추가

@Configuration
 public static class SecuritySecureConfig extends WebSecurityConfigurerAdapter {
     private final String adminContextPath;

     public SecuritySecureConfig(AdminServerProperties adminServerProperties) {
         this.adminContextPath = adminServerProperties.getContextPath();
     }

     @Override
     protected void configure(HttpSecurity http) throws Exception {
         // @formatter:off
         SavedRequestAwareAuthenticationSuccessHandler successHandler = new SavedRequestAwareAuthenticationSuccessHandler();
         successHandler.setTargetUrlParameter("redirectTo");

         http.authorizeRequests()
                 .antMatchers(adminContextPath + "/assets/**").permitAll()
                 .antMatchers(adminContextPath + "/login").permitAll()
                 .anyRequest().authenticated()
                 .and()
                 .formLogin().loginPage(adminContextPath + "/login").successHandler(successHandler).and()
                 .logout().logoutUrl(adminContextPath + "/logout").and()
                 .httpBasic().and()
                 .csrf().disable();
     }
 }

4. Hystrix, Turbine UI 모듈

1.5.x 버전의 경우 hystrix-ui, turbine-ui 모듈을 추가할 수 있다. (2.x 버전은 지원하지 않음)

참고

버전이슈

SpringBoot Admin Sever의 버전과 마이크로 서비스의 SpringBoot(Actuator) 버전에 따라 이슈가 있음 1. SpringBoot Admin Sever : 2.0.0

  Eureka 에 등록된 서버 정보를   SpringBoot Admin에 등록하지 못하는 문제 (springBoot-admin-client를 통해서는 등록 됨)
  (참고 : https://github.com/codecentric/spring-boot-admin/issues/776)

  ==> Spring Boot 2.0.1-SNAPSHOT 사용 권장

SpringBoot Admin Sever : 2.0.1-SNAPSHOT

- admin server issue
   spring-boot-admin-server-ui-hystrix, spring-boot-admin-server-ui-turbine의 최종 버전 1.5.8 이고
   Spring Admin 2.x에서 해당 버전을 지원하지 않음(추후 계획 없음)
   (참고 : https://github.com/codecentric/spring-boot-admin/issues/657)
- client issue
   마이크로 서비스가 Spring Boot 1.x 버전을 사용할 경우 Admin Server에서 모든 Endpoint 지원하지 않음
   (참고 : http://codecentric.github.io/spring-boot-admin/2.0.0/)
   >As some of the actuator endpoints changed with the Spring Boot 2 release not all options might be available (e.g. /metrics endpoint); for some of the endpoints we provide legacy converters.

SpringBoot Admin Server : 1.5.7

 - client issue
     마이크로 서비스가 Spring Boot 2.x 버전을 사용할 경우 Admin Server에서 모든 Endpoint 지원하지 않음

SpringBoot Admin Server와 각 마이크로 서비스의 버전을 맞춰서 사용하는 것을 권장. SpringBoot Admin 2.x를 사용하는 경우 turbine은 별도의 서비스로 제공 해야 함
