docker - 在Bluemix中使用带有redmine docker容器的卷 - Thinbug

我正在尝试使用Redmine官方Docker在Bluemix容器中设置Redmine实例;

我可以构建图像并运行容器而没有任何问题。

如果我向容器添加一个卷，那么构建将在此日志附近失败：

chown：无法读取目录'files / files'：权限被拒绝

8chown：更改'文件'的所有权：权限被拒绝

我理解这种情况正在发生，因为容器中的用户没有读/写权限。

我尝试了一些解决方案，例如使用

USER root

在chown之前。甚至只在chown之后声明音量（如Docker页面中所示）

或者，我遇到的所有其他解决方案都涉及到容器的ssh;我不能做的事情，因为容器永远不会在音量的第一位运行。

这是我的Dockerfile和entrypoint.sh

的副本
