docker run --name elasticsearch -d elasticsearch:6.8.22

启动报错：

[1]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]

解决方法：

  1. 在centos虚拟机中，修改配置sysctl.conf

    vim /etc/sysctl.conf

  2. 加入如下配置

    vm.max_map_count=262144

  3. 启用配置

    sysctl -p

3. 进入容器内部

docker exec -it elasticsearch bash

elasticsearch.yml

cluster.name: "docker-cluster"
network.host: 0.0.0.0

说明：

注意指定jvm.options中的-Xms512m -Xmx512m参数，分配内存应与服务器环境适配，设置内存过大，会导致系统崩溃。
