Error building Docker container images on CentOS 7

Question

I'm trying to build a CentOS 7 Docker container from a minimal template as below

FROM centos:AUTO_SELECT_VERSION

RUN yum -y install yum-plugin-ovl \
 && yum -y install lsof perl file tar gzip gdb \
                   bzip2 openssh rsyslog psmisc initscripts \
                   strace tcpdump gcc

ADD rsyslog.conf /etc/rsyslog.conf
ADD elementtree-1.2.6-20050316.tar.gz /tmp/

but keep facing this glibc dependency error on my VM. Sorry I could not copy paste the error as text, but only have this at the moment

The following are the versions of glibc header/commons installed on my host VM

rpm -qa | grep glibc
glibc-devel-2.17-260.el7_6.6.x86_64
glibc-headers-2.17-260.el7_6.6.x86_64
glibc-2.17-260.el7_6.6.i686
glibc-2.17-260.el7_6.6.x86_64
glibc-common-2.17-260.el7_6.6.x86_64

I'm not sure if this a dependency between 32 and 64-bit packages of glibc installed on my VM. I'm relatively newer to building such containers, so would appreciate some feedback on this.

Answer 1

The problem is that one of your packages tries to install glibc-2.17-260.el7_6.5.i686, which requires the exact same version of glibc-common. However glibc-common is already installed with a slightly superior version number; whence it fails.

What can you do?

• downgrade glibc-common to that exact same version if it is available in your repositories
• make sure glibc*i686 is available in your repositories with the same version as glibc-common; maybe installing the epel-release repositories will help you out with that:

install epel-release first:

RUN yum -y install epel-release\
    && yum -y install yum-plugin-ovl\
