What happened?

When trying to upgrade nodes in OCP 3.11.380 to 3.11.394 using the command:

$ ansible-playbook -i hosts /usr/share/ansible/openshift-ansible/playbooks/byo/openshift-cluster/upgrades/v3_11/upgrade_nodes.yml -e openshift_upgrade_nodes_label="anylabel=true"

It fails with the error message:

Failure summary:


  1. Hosts:    ocpmaster.example.com
     Play:     Filter list of nodes to be upgraded if necessary
     Task:     Map labelled nodes to inventory hosts
     Message:  The conditional check 'hostvars[item].l_kubelet_node_name | lower in nodes_to_upgrade.module_results.results[0]['items'] | map(attribute='metadata.name') | list' failed. The error was: error while evaluating conditional (hostvars[item].l_kubelet_node_name | lower in nodes_to_upgrade.module_results.results[0]['items'] | map(attribute='metadata.name') | list): 'ansible.vars.hostvars.HostVarsVars object' has no attribute 'l_kubelet_node_name'

               The error appears to be in '/usr/share/ansible/openshift-ansible/playbooks/common/openshift-cluster/upgrades/initialize_nodes_to_upgrade.yml': line 25, column 7, but may
               be elsewhere in the file depending on the exact syntax problem.

               The offending line appears to be:

                   # using their openshift.common.hostname fact.
                   - name: Map labelled nodes to inventory hosts
                     ^ here

What did you expect to happen?

Upgrade should complete on the nodes selected by the labels

How to reproduce it (as minimally and precisely as possible)?

Fails
$ ansible-playbook -i hosts /usr/share/ansible/openshift-ansible/playbooks/byo/openshift-cluster/upgrades/v3_11/upgrade_nodes.yml -e openshift_upgrade_nodes_label="anylabel=true"

Works
$ ansible-playbook -i hosts /usr/share/ansible/openshift-ansible/playbooks/byo/openshift-cluster/upgrades/v3_11/upgrade_nodes.yml

Anything else we need to know?

$ ansible-playbook -i hosts /usr/share/ansible/openshift-ansible/playbooks/byo/openshift-cluster/upgrades/v3_11/upgrade_control_plane.yml was executed successfully before the upgrade_nodes.yml playbook was executed.
