docker-compose를 통한 elk 설치 + security 적용

docker-compose를 통한 elk 설치

 

1) 깃허브에서 다운로드를 한다.

- /usr/local/bin/docker-compose 경로에 다운

$ sudo curl -L "https://github.com/docker/compose/releases/download/1.22.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose $ sudo git clone https://github.com/deviantony/docker-elk

 

 

2) 경로로 이동

$ cd /usr/local/bin/docker-elk

 

3) docker-compose.yml 파일 편집

$ sudo vi docker-compose.yml

version: '3.2' services:   elasticsearch:     build:       context: elasticsearch/       args:         ELK_VERSION: $ELK_VERSION     volumes:       - type: bind         source: ./elasticsearch/config/elasticsearch.yml         target: /usr/share/elasticsearch/config/elasticsearch.yml         read_only: true       - type: volume         source: elasticsearch         target: /usr/share/elasticsearch/data     ports:       - "9200:9200"       - "9300:9300"     environment:       ES_JAVA_OPTS: "-Xmx256m -Xms256m"       ELASTIC_PASSWORD: changeme       # Use single node discovery in order to disable production mode and avoid bootstrap checks       # see https://www.elastic.co/guide/en/elasticsearch/reference/current/bootstrap-checks.html       discovery.type: single-node     networks:       - elk   logstash:     build:       context: logstash/       args:         ELK_VERSION: $ELK_VERSION     volumes:       - type: bind         source: ./logstash/config/logstash.yml         target: /usr/share/logstash/config/logstash.yml         read_only: true       - type: bind         source: ./logstash/pipeline         target: /usr/share/logstash/pipeline         read_only: true     ports:       - "5000:5000/tcp"       - "5000:5000/udp"       - "9600:9600"     environment:       LS_JAVA_OPTS: "-Xmx256m -Xms256m"     networks:       - elk     depends_on:       - elasticsearch   kibana:     build:       context: kibana/       args:         ELK_VERSION: $ELK_VERSION     volumes:       - type: bind         source: ./kibana/config/kibana.yml         target: /usr/share/kibana/config/kibana.yml         read_only: true     ports:       - "5601:5601"     networks:       - elk     depends_on:       - elasticsearch networks:   elk:     driver: bridge volumes:   elasticsearch:

 

 

4) 자바 메모리를 변경하자. 

- 글쓴이는 256m -> 1024m로 변경함.

ES_JAVA_OPTS: "-Xmx1024m -Xms1024m" LS_JAVA_OPTS: "-Xmx1024m -Xms1024m"

 

5) 빌드하자.

$ sudo docker-compose build && docker-compose up -d

 

Security 적용

 

1) /usr/local/bin/docker-elk/elasticsearch/config로 이동하고 elasticsearch.yml 편집

$ cd /usr/local/bin/docker-elk/elasticsearch/config $ sudo vi elasticsearch.yml

 

2) xpack.security.authc.api_key.enabled: true로 설정

## Default Elasticsearch configuration from Elasticsearch base image. ## https://github.com/elastic/elasticsearch/blob/master/distribution/docker/src/docker/config/elasticsearch.yml # cluster.name: "docker-cluster" network.host: 0.0.0.0 ## X-Pack settings ## see https://www.elastic.co/guide/en/elasticsearch/reference/current/setup-xpack.html # xpack.license.self_generated.type: trial xpack.security.enabled: true xpack.monitoring.collection.enabled: true

 

 

3) /usr/local/bin/docker-elk/kibana/config로 이동하고 kibana.yml 편집

$ cd /usr/local/bin/docker-elk/kibana/config $ sudo vi kibana.yml

 

4) password 수정, session시간, 암호화키 생성

 - elasticsearch.password: changeme (default값) ->변경

 - xpack.security.encryptionKey : "elasticsearch_security_key__char" -> 32자리

 - xpack.security.sessionTimeout: 600000 -> 세션 설정 30분

--- ## Default Kibana configuration from Kibana base image. ## https://github.com/elastic/kibana/blob/master/src/dev/build/tasks/os_packages/docker_generator/templates/kibana_yml.template.js # server.name: kibana server.host: "0" elasticsearch.hosts: [ "http://elasticsearch:9200" ] xpack.monitoring.ui.container.elasticsearch.enabled: true ## X-Pack security credentials # elasticsearch.username: elastic elasticsearch.password: changeme xpack.security.encryptionKey: "elasticsearch_security_key__char" xpack.security.sessionTimeout: 600000

 

5) elasticsearch 재시작, kibana 재시작

$ sudo docker restart docker_elasticsearch $ sudo docker restart docker_kibana

 

http://localhost:9200 접속

http://localhost:5601 접속

 

usernamer과 password login 후 사용하면 된다.

 

잘사용된다.

 

다음엔 username/password 로그인 사용이 아닌 api key로 접속하는 글을 작성해보겠다.
