方式二：将文件上传至容器，进行安装

将 ik 文件传至服务器

将 ik 复制到容器，并安装

# 查看 ES 的容器ID
[root@localhost ~]# docker ps -a
CONTAINER ID   IMAGE                 COMMAND                  CREATED         STATUS         PORTS                                                                                  NAMES

# 将it 插件，复制到容器中

Continue with installation? [y/N]y
-> Installed analysis-ik
[root@ad684997e228 elasticsearch]#

重启容器

docker restart xxx

如果不重启会报：failed to find global analyzer [ik_smart]

{
    "error": {
        "root_cause": [
            {
                "type": "illegal_argument_exception",
