What happened?

Verify whether main_access_ip is present inside the hostvars dictionary when using the --limit option.

executing cluster.yml playbook with --limit(only etcd,kube_control_plane) getting below error on Task

Task: kubernetes/preinstall : Hosts | create hosts list from inventory

The task includes an option with an undefined variable. The error was: 'ansible.vars.hostvars.HostVarsVars object' has no attribute 'main_access_ip'. 'ansible.vars.hostvars.HostVarsVars object' has no attribute 'main_access_ip'

Please Confirm the presence of the main_access_ip variable in hostvars before access the variable.

Missing if condition to check the presence of main_access_ip in hostvars.

{{ hostvars[item]['main_access_ip'] }} {{ hostvars[item]['ansible_hostname'] | default(item) }}.{{ dns_domain }} {{ hostvars[item]['ansible_hostname'] | default(item) }}

What did you expect to happen?

Need to verify the presence of main_access_ip in hostvars items before access the vars to avoid undefined variable error with limit option.

How can we reproduce it (as minimally and precisely as possible)?

Adding new etcd node to existing cluster and execute cluster.yml with --limit option.

The error appears to be in '/roles/kubernetes/preinstall/tasks/0090-etchosts.yml': line 2, column 3, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:
