Hello all,

I have a play I want to run wich deletes all hosts matching a certain criteria:

tasks:
  - name: Delete unavailable nodes
    zabbix_host:
     server_url: http://zabbix.aa.net/zabbix
     login_user: Admin
     login_password: aq!
     host_groups: Discovered hosts
     status: disabled
     state: absent
     host_name: "{{ item }}"
    with_items:
     - ip-10-1-*-*.us-west-2.compute.internal

The above doesnt work, but if I list out the items

with_items:
     - ip-10-1-65-27.us-west-2.compute.internal
     - ip-10-1-65-28.us-west-2.compute.internal
     - ip-10-1-65-37.us-west-2.compute.internal

then it works, but I want it to be dynamic and find all ips matching

     - ip-10-1-*-*.us-west-2.compute.internal

any help please?

with_items requires a list to iterate over. I think one way of achieving your outcome is to create a group in the inventory and populate it with the hosts and run the playbook against that group.

Thanks for your reply, but the issue with that is , the servers in aws get removed and created again each build( every 1hr) , so I would need a way to get the servers dynamically.Is there anyway to do that? i want to dynamically have a list, not create a list of servers in inventory.

Hi,

If you use the dynamic inventory script (ec2.py) you can use tags to dynamically create groups. Have a look here: https://aws.amazon.com/blogs/apn/getting-started-with-ansible-and-dynamic-amazon-ec2-inventory-management/

kind regards

Hi,

can you try "with_fileglob" ? Refer in http://docs.ansible.com/ansible/latest/playbooks_loops.html#id4

with_lines: cat "file"
