Thanks Mike. However, i dont want to use it as confluent.platform.resolve\_hostname. We are customising as per our requirement so how do we restrain from using confluent.platform.resolve\_hostname cant we directly use “|resolve\_hostname” or similar to it . I wanted to avoid using collection and use it as a role.

Im not sure what you mean by this. Could you elaborate?

If you just dont want to use this specific collection, you could either maintain a copy of the plugin yourself, or write the logic in jinja/ansible. Maybe like

```auto
..... if host == inventory_hostname else (
  hostvars[host]['hostname_aliasing_enabled'] | ternary(
    (
      hostvars[host]['hostname'] | default(
        hostvars[host]['ansible_host'] | default(
          hostvars[host]['inventory_hostname']
        )
      )
    ),
    (
      hostvars[host]['inventory_hostname']
    )
  )
)

```

Yes i want to maintain the local copy of plugin.  
Now what happens is because the variable is used like "confluent.platform.resolve\_hostname " its obliged to have ansible colletion FCQN like ansible/collections/ansible\_collections/confluent/platform/ . I dont want this to have it on control machine. Is it not possible to use simply hostvars[host]|resolve\_hostname instead hostvars[host]|confluent.platform.resolve\_hostname. If i can use like this i dont need to have ansible collection directory structure to maintain. I can simply use it as a role.

You can place the copy of the plugin locally as described here: [Filter plugins — Ansible Community Documentation](https://docs.ansible.com/ansible/latest/plugins/filter.html#using-filter-plugins)

Or you can adjust your variable like this. Im not confident this works, but I think you can take it from here

```auto
zookeeper_servers: “{% for host in groups[‘zookeeper’] %}{% if loop.index > 1%},{% endif %}server.{{ hostvars[host][‘zookeeper_id’] | default(groups.zookeeper.index(host) + 1)}}={{ zookeeper_current_node_hostname if host == inventory_hostname else (hostvars[host]['hostname_aliasing_enabled'] | ternary((hostvars[host]'hostname'] | default(hostvars[host]['ansible_host'] | default(hostvars[host]['inventory_hostname']))), (hostvars[host]['inventory_hostname']))) }}:{{zookeeper_peer_port}}:{{zookeeper_leader_port}}{% endfor %}”

```
