Docker 安装elasticsearch和kibana

可能遇到的问题

• es暴露的端口很多
• es十分耗内存
• es的数据一般需要放置到安全目录！挂载
• --net somenetwork ？网络配置

启动elasticsearch

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

docker run -d --name elasticsearch -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" elasticsearch:7.6.2

# 启动后Linux就卡住了， docker stats 查看cpu的状态

测试es是否安装成功

curl localhost:9200
{
  "name" : "86f72bacc50f",
  "cluster_name" : "docker-cluster",
  "cluster_uuid" : "6RGLiRo1TmGVU8CUnV4olg",
  "version" : {
    "number" : "7.6.2",
    "build_flavor" : "default",
    "build_type" : "docker",
    "build_hash" : "ef48eb35cf30adf4db14086e8aabd07ef6fb113f",
    "build_date" : "2020-03-26T06:34:37.794943Z",
    "build_snapshot" : false,

    "minimum_index_compatibility_version" : "6.0.0-beta1"
  },
  "tagline" : "You Know, for Search"
}

关闭es，增加内存的限制，修改配置文件， -e 环境配置修改

docker run -d --name elasticsearch02 -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" -e ES_JAVA_OPTS="-Xms64m -Xmx512m" elasticsearch:7.6.2
