linux下用docker部署es和kibana

在linux下用docker部署es和kibana
1、在某个文件夹下创建docker-compose.yml文件，并把以下内容copy进去

version: '3'
services:elasticsearch:image: docker.elastic.co/elasticsearch/elasticsearch:7.6.0container_name: elasticsearchenvironment:- discovery.type=single-node  #单节点- ES_JAVA_OPTS=-Xms512m -Xmx512m   # 设置ES内存大小为512MB，我的服务器内存不大，所以设置512mports:- "9200:9200"networks:- elastickibana:image: docker.elastic.co/kibana/kibana:7.6.0container_name: kibanaports:- "5601:5601"networks:- elasticnetworks:elastic:driver: bridge

2、然后用docker-compose up 启动服务
3、在启动过程中，发现es没有启动起来于是如下命令查看日志，最后发现是内存不够，所以杀掉了一些其他不必要的进程释放内存

docker logs elasticsearch

4、查看可用内存命令

free -h

5、重新用后台启动

docker-compose up -d

6、启动成功后，用如下命令检查,看到es和kibana都是running状态

docker-compose ps

7、用命令行来访问es是否正常启动起来，windows环境下打开dos窗口，执行以下命令,或者直接在linux系统里面执行如下命令，看到如下返回内容即是启动成功

curl -X GET ip:9200

访问es响应的内容
