ELK Docker Install

ELK Docker 安裝步驟

---

一、架構

Elastic stack架構圖如下

二、安裝步驟

透過Docker安裝，是很容易的，重點是所有的Container都要在同一個網路下面

此安裝步驟根據官方文件分享

1. 新增docker-compose.yml

   ​​​​version: '2.2'
   ​​​​services:
   ​​​​  es01:
   ​​​​    image: docker.elastic.co/elasticsearch/elasticsearch:7.12.0
   ​​​​    container_name: es01
   ​​​​    environment:
   ​​​​      - node.name=es01
   ​​​​      - cluster.name=es-docker-cluster
   ​​​​      - discovery.seed_hosts=es02,es03
   ​​​​      - cluster.initial_master_nodes=es01,es02,es03
   ​​​​      - bootstrap.memory_lock=true
   ​​​​      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
   ​​​​    ulimits:
   ​​​​      memlock:
   ​​​​        soft: -1
   ​​​​        hard: -1
   ​​​​    volumes:
   ​​​​      - data01:/usr/share/elasticsearch/data
   ​​​​    ports:
   ​​​​      - 9200:9200
   ​​​​    networks:
   ​​​​      - elastic
   
   ​​​​es02:
   ​​​​    image: docker.elastic.co/elasticsearch/elasticsearch:7.12.0
   ​​​​    container_name: es02
   ​​​​    environment:
   ​​​​      - node.name=es02
   ​​​​      - cluster.name=es-docker-cluster
   ​​​​      - discovery.seed_hosts=es01,es03
   ​​​​      - cluster.initial_master_nodes=es01,es02,es03
   ​​​​      - bootstrap.memory_lock=true
   ​​​​      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
   ​​​​    ulimits:
   ​​​​      memlock:
   ​​​​        soft: -1
   ​​​​        hard: -1
   ​​​​    volumes:
   ​​​​      - data02:/usr/share/elasticsearch/data
   ​​​​    networks:
   ​​​​      - elastic
   
   ​​​​  es03:
   ​​​​    image: docker.elastic.co/elasticsearch/elasticsearch:7.12.0
   ​​​​    container_name: es03
   ​​​​    environment:
   ​​​​      - node.name=es03
   ​​​​      - cluster.name=es-docker-cluster
   ​​​​      - discovery.seed_hosts=es01,es02
   ​​​​      - cluster.initial_master_nodes=es01,es02,es03
   ​​​​      - bootstrap.memory_lock=true
   ​​​​      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
   ​​​​    ulimits:
   ​​​​      memlock:
   ​​​​        soft: -1
   ​​​​        hard: -1
   ​​​​    volumes:
   ​​​​      - data03:/usr/share/elasticsearch/data
   ​​​​    networks:
   ​​​​      - elastic
   
   ​​​​  kib01:
   ​​​​    image: docker.elastic.co/kibana/kibana:7.12.0
   ​​​​    container_name: kib01
   ​​​​    ports:
   ​​​​      - 5601:5601
   ​​​​    environment:
   ​​​​      ELASTICSEARCH_URL: http://es01:9200
   ​​​​      ELASTICSEARCH_HOSTS: '["http://es01:9200","http://es02:9200","http://es03:9200"]'
   ​​​​    networks:
   ​​​​      - elastic
   
   ​​​​volumes:
   ​​​​  data01:
   ​​​​    driver: local
   ​​​​  data02:
   ​​​​    driver: local
   ​​​​  data03:
   ​​​​    driver: local
   
   ​​​​networks:
   ​​​​  elastic:
   ​​​​    driver: bridge
   

2. 確保Docker Engine 至少有4GB

3. Run docker-compose 以執行 Elasticsearch 三個節點，與 Kibana
   docker-compose up

4. 開啟 kibana: http://localhost:5601
