Description Kenjiro Nakayama 2017-11-09 05:36:36 UTC
Description of problem:
- Containerized uninstallation playbook does not clean up HAProxy configuration

Version-Release number of the following components:
  [root@knakayam-ose36-master1 ~]# rpm -q openshift-ansible
  [root@knakayam-ose36-master1 ~]# rpm -q ansible
  [root@knakayam-ose36-master1 ~]# ansible --version
    config file = /etc/ansible/ansible.cfg
    configured module search path = Default w/o overrides
    python version = 2.7.5 (default, Feb 11 2014, 07:46:25) [GCC 4.8.2 20140120 (Red Hat 4.8.2-13)]

How reproducible: 100%

Steps to Reproduce:

1. Install with containerized installation

  # ansible-playbook     /usr/share/ansible/openshift-ansible/playbooks/byo/config.yml




2. Uninstall cluster

  # ansible-playbook     /usr/share/ansible/openshift-ansible/playbooks/adhoc/uninstall.yml

3. Check /etc/systemd/system/haproxy.service

  #  ls /etc/systemd/system/haproxy.service

Actual results:
- /etc/systemd/system/haproxy.service remains.
- Due to this, if we re-install with "non-containerized" installation, haproxy service fails to start with following error.

  Nov 08 17:38:39 knakayam-ose36-lb1 systemd[1]: haproxy.service: main process exited, code=exited, status=1/FAILURE
  Nov 08 17:38:46 knakayam-ose36-lb1 docker[2321]: Error response from daemon: No such container: openshift_loadbalancer
  Nov 08 17:38:46 knakayam-ose36-lb1 systemd[1]: haproxy.service: control process exited, code=exited status=1
  Nov 08 17:38:46 knakayam-ose36-lb1 systemd[1]: Failed to start haproxy.service.

Expected results:
- /etc/systemd/system/haproxy.service and /etc/systemd/system/haproxy.service.d/limits.conf are removed during the uninstallation.

Comment 4 Wenkai Shi 2018-01-26 09:22:17 UTC
Check with version openshift-ansible-, code seems didn't merged.
Looks no build in Errata by the way.

# rpm -q openshift-ansible

# grep -nir "haproxy.service" /usr/share/ansible/openshift-ansible/playbooks/adhoc/uninstall.yml

Comment 7 Wenkai Shi 2018-01-30 08:16:50 UTC
Verified with version openshift-ansible-, /etc/systemd/system/haproxy.service and /etc/systemd/system/haproxy.service.d/limits.conf are removed during the uninstallation.

# cat /etc/systemd/system/haproxy.service
cat: /etc/systemd/system/haproxy.service: No such file or directory
# cat /etc/systemd/system/haproxy.service.d/limits.conf
cat: /etc/systemd/system/haproxy.service.d/limits.conf: No such file or directory
