Issue #3891
Updated by ragbalak over 5 years ago
The pulp-ci which installs pulp in a remote environment fails to install when docker is installed in the environment.
*This was tested with pulp 2.17*
h2. Steps to reproduce
* Install docker in a f27 VM
<pre>
dnf install docker -y
</pre>
* Run the pulp-ci that installs pulp in the remote
<pre>
ansible-playbook ci/ansible/pulp_server.yaml --inventory root@hostname, -e pulp_build=nightly -e pulp_version="'2.17'"
</pre>
* During installation, the install OS tree task failed thereby terminating the ci installer
*Root Cause :*
Docker installs a dependency: subscription-manager-rhsm-certificates-1.21.x which obsoletes python-rhsm-certificates that causes a dependency problem for os tree installation.
This issue happens only when docker is pre installed. It doesn't happen in the reverse situation ( install docker after pulp installation). This was found when trying the nodepool migration for docker-np images and running pulp installer on top of that.
The whole stack trace is attached with this issue.
