docker部署elasticsearch-+-Kibana(6-8)-+-SpringBoot-2-1-6

elasticsearch快速开始

docker run -d --name elasticsearch --net somenetwork -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" elasticsearch:6.8.11

环境Linux

该vm.max_map_count内核设置需要至少设置为262144用于生产。取决于您的平台：

• 的Linux

  该vm.max_map_count设置应该在/etc/sysctl.conf中永久设置：

vim /etc/sysctl.conf
# 这里设置多一点
vm.max_map_count=655360
# 刷新
sysctl -p

官网es6.8安装教程

https://www.elastic.co/guide/en/elasticsearch/reference/6.8/docker.html

注意SpringBoot和ES的版本

Elasticsearch :docker-compose.yml

version: '3'
services:
  elasticsearch:
    image: elasticsearch:6.8.11
    container_name: myES
    environment:
      - TZ="Asia/Shanghai"
      - cluster.name=cluster1
      - bootstrap.memory_lock=true
      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
    ulimits:
      memlock:
        soft: -1
        hard: -1
    volumes:
      - /var/docker/elasticsearch/data:/usr/share/elasticsearch/data:rw
    ports:
      - 9200:9200
      - 9300:9300

Kibana:docker-compose.yml

官网参考

https://www.elastic.co/guide/en/kibana/6.8/docker.html#docker

version: '3'
services:
  kibana:
    image: kibana:6.8.11
    container_name: myKibana
    ports:
      - 5601:5601
    environment:
      TZ: "Asia/Shanghai"
      SERVER_NAME: kibana
      ELASTICSEARCH_HOSTS: http://elasticsearch.example.org
    volumes:
      - /var/docker/kibana/config:/usr/share/kibana/config

整合成一个docker-compose.yml

  elasticsearch:
    image: elasticsearch:6.8.11
    container_name: myES
    restart: always
    environment:

    ports:
      - 9200:9200
      - 9300:9300
  kibana:
    image: kibana:6.8.11
    container_name: myKibana
    restart: always
