使用yum安装时拒绝Dockerfile权限

使用yum安装时拒绝Dockerfile权限,docker,dockerfile,centos7,rpm,yum,Docker,Dockerfile,Centos7,Rpm,Yum,我正在尝试从此图像创建Dockerfile: 我的Dockerfile: FROM centos/python-27-centos7:latest RUN yum install rpm-build -y WORKDIR /usr/src/app COPY requirements.txt ./ RUN pip install --no-cache-dir -r requirements.txt CMD ["bash"] 但我得到了下一个错误: => ER

我正在尝试从此图像创建Dockerfile:

我的Dockerfile:

FROM centos/python-27-centos7:latest

RUN yum install rpm-build -y

WORKDIR /usr/src/app

COPY requirements.txt ./
RUN pip install --no-cache-dir -r requirements.txt


CMD ["bash"]
但我得到了下一个错误:

 => ERROR [2/9] RUN yum install rpm-build -y                                                                                                                                0.6s

我尝试添加sudo,但仍然不起作用。
这里出了什么问题?

尝试使用用户根目录

    FROM centos/python-27-centos7:latest

    USER root
    RUN yum install rpm-build -y
    
    WORKDIR /usr/src/app
    
    COPY requirements.txt ./
    
    RUN pip install --no-cache-dir -r requirements.txt
    
    
    CMD ["bash"]

@SiHa我不确定,因为然后
yum安装
安装到另一个目录。。。也许我需要以root用户身份安装,但需要替换一些二进制文件或添加到PATH.。然后使用
运行chmod 0644
