Description Pablo Alonso Rodriguez 2019-03-20 12:42:07 UTC 
Description of problem:

When etcd runs co-located on a master, it is deployed as a static pod, so it should not be necessary to install etcd rpm. However it is installed.

Version-Release number of the following components:

$ rpm -q openshift-ansible
openshift-ansible-3.11.51-2.git.0.51c90a3.el7.noarch

$ rpm -q ansible
ansible-2.7.1-1.el7.noarch

$ ansible --version
ansible 2.7.1
  config file = /opt/mev/ansible.cfg
  configured module search path = [u'/root/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python2.7/site-packages/ansible
  executable location = /bin/ansible
  python version = 2.7.5 (default, May 31 2018, 09:41:32) [GCC 4.8.5 20150623 (Red Hat 4.8.5-28)]

How reproducible:

Always

Steps to Reproduce:
1. Install a cluster with etcd co-located with masters

Actual results:
etcd rpm is installed, although etcd is correctly deployed as static pod

Expected results:
etcd rpm should not be installed

Additional info:

etcdctl2 and etcdctl3 functions are properly designed to use "/usr/local/bin/master-exec etcd etcd" when static pod is present, so it should not be necessary to have etcdctl binary on host for them to work.
