Description Lukas Svaty 2017-04-04 13:35:21 UTC

Description of problem:
When there was no ssh connection, and host is not saved in .ssh/known_hosts ansible playbook becomes interactive and need yes to add ECDSA key fingerprint. Not sure how I got to the state that host wasn't in the .ssh/known_hosts, but it was quite fresh engine upgraded from older 4.1.0 version.

For reproducer you just need to remove the host from it.


Version-Release number of selected component (if applicable):
ovirt-engine-metrics-1.0.1-1.el7ev.noarch

How reproducible:
100%

Steps to Reproduce:
1. remove Host from .ssh/known_hosts
2. run /usr/share/ovirt-engine-metrics/setup/ansible/configure_ovirt_hosts_for_metrics.sh 

Actual results:
Ansible playbook waits for yest input on adding host to known

Expected results:
Should add unrecognized hosts automatically

Additional info:
[root ~]# /usr/share/ovirt-engine-metrics/setup/ansible/configure_ovirt_hosts_for_metrics.sh 

PLAY [Get ca cert from local file] *********************************************

TASK [setup] *******************************************************************
The authenticity of host 'ip.me (ip.me)' can't be established.
ECDSA key fingerprint is 8c:e0:7a:fb:1a:e3:a1:b5:87:80:aa:40:0c:00:00:b9.
Are you sure you want to continue connecting (yes/no)? yes
ok: [ip.me]

Filed bug 1467898 so that we try to find a better solution, as I do not like current. But could not find something simple and better.
