docker run 上带有 --user 选项的 Docker 入口点错误

Question

当我希望我的容器写为非根文件时，我发现 docker run 存在这个问题。

当我使用这种命令（入口点被覆盖）时，我没有任何问题：

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

它工作正常，我可以使用I have no name! 用户帐户 x) 访问容器

但是，没有像这里这样的入口点的覆盖：

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

我有这个错误：

请向我询问更多信息。

在 DockerFile 上添加这个解决了

RUN useradd MYUSERNAME --uid 1001
