Description of problem: node scale failes on openshift_master_facts everytime with below error : the field 'args' has an invalid value, which appears to include a variable that is undefined. The error was: {{ openshift_hosted_metrics_public_url | default('hawkular-metrics.' ~ (openshift.master.default_subdomain | default(openshift_master_default_subdomain ))) | oo_hostname_from_url }}: 'dict object' has no attribute 'master' The error appears to have been in '/usr/share/ansible/openshift-ansible/roles/openshift_master_facts/tasks/main.yml': line 31, column 3, but may be elsewhere in the file depending on the exact syntax problem. The offending line appears to be: - name: Set master facts ^ here Version-Release number of the following components: # rpm -qa | grep openshift-ansible openshift-ansible-3.3.54-1.git.0.61a1dee.el7.noarch openshift-ansible-roles-3.3.54-1.git.0.61a1dee.el7.noarch openshift-ansible-docs-3.3.54-1.git.0.61a1dee.el7.noarch openshift-ansible-filter-plugins-3.3.54-1.git.0.61a1dee.el7.noarch openshift-ansible-callback-plugins-3.3.54-1.git.0.61a1dee.el7.noarch openshift-ansible-playbooks-3.3.54-1.git.0.61a1dee.el7.noarch openshift-ansible-lookup-plugins-3.3.54-1.git.0.61a1dee.el7.noarch ansible --version ansible 2.2.0.0 config file = /etc/ansible/ansible.cfg configured module search path = Default w/o overrides How reproducible: Steps to Reproduce: 1. 2. 3. Actual results: Fails on collecting master facts Expected results: should suceed Additional info: Please attach logs from ansible-playbook with the -vvv flag
A workaround would be to set openshift_hosted_metrics_public_url variable in the inventory to the url where metrics is configured. ie: openshift_hosted_metrics_public_url: https://hawkular-metrics.osc1.cp1.cathaypacific.com/hawkular/metrics Also, while I don't think that this would address the problem, they are using a version of openshift-ansible that's more than two years of out date. There have been over 300 commits to the branch since openshift-ansible-3.3.54-1.
Performed a successful install and scaleup with openshift-ansible-3.3.54-1 without metrics enabled. Will test again with metrics enabled.
