Steps to reproduce the behavior

Follow instructions to install docker on centos 7

https://docs.docker.com/engine/installation/linux/centos/#install-using-the-repository

[kristiehoward]

Update: running sudo yum erase docker-engine-selinux fixed the issue.... but I don't know why the issue exists in the first place 😅

[kristiehoward]

(and i had this issue on all 4 machines)

[kristiehoward]

And I did run the Uninstall instructions before just to make sure, which said there was nothing to remove:

sudo yum remove docker \
                  docker-common \
                  container-selinux \
                  docker-selinux \
                  docker-engine

[cpuguy83]

This is because previously we reliaed on docker-selinux (or docker-ce-selinux) and have moved to container-selinux.
We'll need to update the docs.

I'll check if there's something we can do in the RPM spec.

[cpuguy83]

Maybe we need to Obsoletes: docker-ce-selinux?

the same problem when install in a pure centos7.2 system which has never installed old docker version, out put as follows:

and neither rpm -Va --nofiles --nodigest nor yum install docker-ce-17.03.2.ce-1.el7.centos --skip-broken luck at all

[terminatorheart]

and docker-ce-17.06.0.ce-1.el7.centos can be installed successfully. how ever, rancher not support this version right now

[prakashriti]

Installed 17.03.0.ce-1.el7.centos last month and everything worked perfectly. Now the same installation process is throwing the above mentioned error. if i install the latest version of docker-ce, everything seems to be working. I want to install docker in a machine and connect the container to a overlay network. So i would prefer to install 17.03.0.ce-1.el7.centos and maintain same version in all the machines under overlay network. Is it any workaround to get rid of this dependency issue. I am using centos 7 and need to install docker 17.03.0. Thanks in advance

[andrewhsu]

For the initial cause this issue was filed, the docker-ce 17.06.0 packages can now install properly on centos 7.

@terminatorheart for your specific situation of installing docker-ce 17.03.2, you'll need to peg the version specifically and pass a setopt flag to ignore the Obsoletes that was introduced with docker-ce 17.06.0 just to get the older 17.03.2 package installed:

$ yum install --setopt=obsoletes=0 \
   docker-ce-17.03.2.ce-1.el7.centos.x86_64 \
   docker-ce-selinux-17.03.2.ce-1.el7.centos.noarch # on a new system with yum repo defined, forcing older version and ignoring obsoletes introduced by 17.06.0

[terminatorheart]

@andrewhsu nice, it worked well. that's so kind of you! if the doc here https://docs.docker.com/engine/installation/linux/docker-ce/centos/ updated will be of great helpful

@prakashriti i think you meet the same problem of mine. and please just follow andrewhsu's solution
