运行容器时权限被拒绝（docker 1.12.5）

我试图在安装了Docker 1.12.5的新创建的VM上运行ElasticSearch容器，但遇到了

权限被拒绝
异常。让我困惑的是，在我的旧虚拟机中，Docker 1.12.2运行得很好。我错过了什么

例外情况：

由于映像在另一个VM上工作，我相信它的配置应该是正确的。我也不认为这个问题来自ElasticSearch，因为我似乎有另一张图像有同样的问题（H2）。我对Docker和Linux都是初学者。
在中复制配置后设置文件权限：

COPY config ./config
RUN chown -R elasticsearch:elasticsearch /usr/share/elasticsearch/config

您还可以创建并
chown
作为root用户的
/usr/share/elasticsearch
目录，然后完成处理
/usr/share/elasticsearch
内容的其余步骤，作为
用户elasticsearch
将卷权限更改为777示例：-chmod 777/path/to/volume

请勿授予递归权限
谢谢。在复制成功后设置权限。不知道为什么它在我以前的虚拟机上工作，但我现在很高兴。干杯。从windows到unix的权限映射总是有点混乱。只有当源代码是linux文件系统时，您才能信任它，因此最好只在docker文件中设置您需要的内容，这样就不会出错。
