Dockerfile Permission Denied when using yum install

I'm trying to create Dockerfile from this Image: https://hub.docker.com/r/centos/python-27-centos7

My 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"]

But I got next error:

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

I tried add sudo but still doesn't work. What is wrong here?

Solution

  • Try to use the user root

        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"]
