拉取镜像
docker pull docker.elastic.co/elasticsearch/elasticsearch:7.1.0
本地下载太慢，我这里用我自己的香港服务器执行上述命令拉取镜像，导出到服务器本地，再下载下来，重新导入到虚拟机中。
# docker下导出镜像到本地
mkdir -p /data/docker_images/
docker save > /data/docker_images/es-7.1.0.tar.gz docker.elastic.co/elasticsearch/elasticsearch:7.1.0
# 下载下来
sz /data/docker_images/es-7.1.0.tar.gz
# 文件上传到虚拟机/data/docker_images/目录下、加载到docker中
docker load < /data/docker_images/es-7.1.0.tar.gz
单机版
集群版
创建网络
docker network create elk

两个报错解决方案(宿主机上配置即可，无需到容器内配置)
max file descriptors [4096] for elasticsearch process is too low, increase to at least [65536]
vim /etc/security/limits.conf
# 添加如下配置
*** hard nofile 65536
*** soft nofile 65536
*** 是启动ES的用户
max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [655360]
vim /etc/sysctl.conf
# 添加如下配置
vm.max_map_count=655360
保存后，执行sysctl -p ，修改生效。
sysctl -p
