Hi, Instead of passing to specific hostgroup, can i pass the regex to “hosts: ” for the play hosts ?. eg:- - name: pre-step of the setup process hosts: cluster\_.\* gather\_facts: false strategy: free any\_errors\_fatal: true tasks: - include : roles/setup\_node/tasks/pre-setup.yml Basically i have dynamic hosts group name prefix with “cluster\_”. The above method of regex way is not working ?. any tricks or best practices to get the dynamic inventory. another requirement:- [cluster\_x1] host1 host2 [cluster\_x2] host3 host4 In the above host inventory file, if host2 fails on play, i would like to not to consider other tasks in the play for both host1, host2 for cluster cluster\_x1. Is that possible ?. Thanks venkat ---

Never done it, but i think you can use limit: [https://ansible-tips-and-tricks.readthedocs.io/en/latest/ansible/commands/](https://ansible-tips-and-tricks.readthedocs.io/en/latest/ansible/commands/) ---

Hi , limit:1 max\_fail\_percent:0 This should help you as it will limit the number of hosts your playbook is run as well if it fails it will not run on any more hosts . dynamic inventory i am still trying to understand it , Here is a link from which can help you [docs.ansible.com/ansible/latest/user\_guide/intro\_dynamic\_inventory.html](http://docs.ansible.com/ansible/latest/user_guide/intro_dynamic_inventory.html) ta ---

True. I can make it to max\_fail\_percent:99 to get it fail if any one fails. but hosts regex part is still in question to me ☹ Thanks venkat ---

It doesn't support regex but pattern, all about it in the docs [https://docs.ansible.com/ansible/latest/user\_guide/intro\_patterns.html](https://docs.ansible.com/ansible/latest/user_guide/intro_patterns.html)
