Comment 1 Michael Gugino 2018-12-03 17:06:57 UTC

3.10.z tracking bug.

Comment 4 Scott Dodson 2019-01-24 14:54:52 UTC

In openshift-ansible-3.10.91-1 and later

Comment 5 sheng.lao 2019-01-25 08:17:04 UTC

1. Reproduce the failure
# rpm -qa |grep openshift-ansible
openshift-ansible-3.10.57-1.git.0.787bf7c.el7.noarch

After the finished playbook uninstall.yml with enabled openshift_uninstall_docker, I check with command:
# rpm -qa |grep docker
docker-1.13.1-88.git07f3374.el7.x86_64

Re-install OCP with commands:
# ansible-playbook -i inventory.yml playbooks/prerequisites.yml 

And get error messages from docker service:
# systemctl status docker
Jan 25 01:48:59 xxxx dockerd-current[65299]: /usr/bin/docker-containerd: line 2: /etc/sysconfig/docker: No such file or directory


2. Verify the Patch
Check in the uninstalled enviroment
# rpm -qa |grep openshift-ansible
openshift-ansible-3.10.104-1.git.0.79f87f7.el7.noarch

# rpm -qa |grep docker
#

Re-install OCP and get the same error:
# systemctl status docker
Jan 25 03:10:24 xxx dockerd-current[47247]: /usr/bin/docker-containerd: line 2: /etc/sysconfig/docker: No such file or directory

# rpm -qf /etc/sysconfig/docker
docker-common-1.13.1-88.git07f3374.el7.x86_64


3. Result: Failed, because installer need to uninstall the rpm of docker-common
