Description Bruno Andrade 2018-02-02 13:49:27 UTC

Opened this bug to track this issue (https://github.com/openshift/openshift-ansible/issues/6911/) on OCP. A PR is already opened: 
https://github.com/openshift/openshift-ansible/pull/6910/

I wasn't using any version constraint for the installation of openshift-ansible-playbooks RPM package. Earlier this week, the version of the RPM package was 3.7.14-1.git.0.4b35b2d.el7. Since the package upgraded to 3.7.23-1.git.0.bc406aa.el7 installation of the cluster is failing

Version
ansible 2.4.2.0
openshift-ansible-3.7.23-1.git.0.bc406aa.el7.noarch
Steps To Reproduce
yum install openshift-ansible-3.7.23-1.git.0.bc406aa.el7.noarch
Add the configuration below to the inventory file.
/usr/bin/ansible-playbook -vvv /usr/share/ansible/openshift-ansible/playbooks/byo/config.yml
openshift_hosted_logging_deploy=true
openshift_hosted_logging_storage_kind=dynamic
openshift_hosted_logging_elasticsearch_cluster_size=1
openshift_logging_elasticsearch_nodeselector="{'purpose': 'infra'}"
openshift_logging_curator_nodeselector="{'purpose': 'infra'}"
openshift_logging_kibana_nodeselector="{'purpose': 'infra'}"
openshift_logging_mux_nodeselector="{'purpose': 'infra'}"
openshift_logging_curator_default_days=90
openshift_logging_curator_run_hour=0
openshift_logging_curator_run_minute=0
Expected Results
Observed Results
The reason is Ansible is using non-interactive SSH connections which means PATH is the system default such as /sbin:/bin:/usr/sbin:/usr/bin. At the same time, the line below is calling an oc command with a relative path which is not in PATH.

TASK [openshift_logging_elasticsearch : command] *******************************
Friday 26 January 2018  18:04:18 +0000 (0:00:01.007)       0:16:18.018 ******** 
fatal: [ip-10-113-23-117.eu-west-2.compute.internal]: FAILED! => {"changed": false, "cmd": "oc get pod -l component=es,provider=openshift -n logging -o 'jsonpath={.items[*].metadata.name}'", "msg": "[Errno 2] No such file or directory", "rc": 2}
I think oc command should be called with the absolute path

Additional Information
Red Hat Enterprise Linux Server release 7.3 (Maipo)

Comment 1 Peter Verbist 2018-02-07 22:49:09 UTC

Dear reader,

Indeed. Had the same issue but on atomic hosts. This means I cannot just modify the path. My path = /sbin:/bin:/usr/sbin:/usr/bin ; but on the atomic host, the oc command can be found in: /usr/local/bin
As a result I changed the following:

Main issue should be handled but in the mean time, you can deploy EFK on your cluster.

Kind regards,

Peter
