在docker run上使用--user选项的Docker Entrypoint错误

Question

I discover this problem with a docker run when i want just that my container write as not root files.

When i use this kind of command (where the entrypoint is overided) i don't have any problem :

docker run -u `id -u $USER` --entrypoint  bash -it --rm -v somepath:somepathincontainer IMAGE

It's work and i have access to the container with I have no name! user account x)

But, without overide of the entrypoint like here :

docker run -u `id -u $USER` -it --rm -v somepath:somepathincontainer IMAGE

I have this error :

Edit 1

I have no name!@c9368637178d:/$ id
uid=1001 gid=0(root) groups=0(root)

Ask to me for further information.
