Description Weinan Liu 2018-05-21 03:25:51 UTC

Description of problem:
Two different environment variables used to control if NPD install :
Using ansible playbook: openshift_node_problem_detector_state=present
During cluster deployment (on Jenkins): openshift_node_problem_detector_install: true
It would be confusing for the users.

Version-Release number of selected component (if applicable):
[root@qe-weinliu310-2master-etcd-1 ~]# oc version
oc v3.10.0-0.30.0
kubernetes v1.10.0+b81c8f8
features: Basic-Auth GSSAPI Kerberos SPNEGO

Server https://qe-weinliu310-2master-etcd-1:8443
openshift v3.10.0-0.30.0
kubernetes v1.10.0+b81c8f8
[root@qe-weinliu310-2master-etcd-1 ~]# uname -a
Linux qe-weinliu310-2master-etcd-1 3.10.0-862.el7.x86_64 #1 SMP Wed Mar 21 18:14:51 EDT 2018 x86_64 x86_64 x86_64 GNU/Linux
[root@qe-weinliu310-2master-etcd-1 ~]# cat /etc/redhat-release 
Red Hat Enterprise Linux Server release 7.5 (Maipo)

How reproducible:
always

Steps to Reproduce:
1. As description

Actual results:
Two different environment variables used

Expected results:
Unique environment variable used to control both of the two install methods, to avoid confusing.

Additional info:
N/A

https://trello.com/c/OA9z4cMU/701-8-node-deliver-node-problem-detector-for-tech-preview says NPD is tech-preview therefore not a 3.10 blocker here.

any plans for getting this updated?

Comment 3 Scott Dodson 2019-01-28 18:30:30 UTC

openshift_node_problem_detector_install = true should be the only variable that's required. Internal to the role openshift_node_problem_detector_install is used to force removal of the npd and should not need to be set to install.
