Question

I have a playbook that uses multiple hostgroup like (appserver,app01server,dbserver,db01server) and if the hostgroup contains db* then the condition should execute. I have written something like this :

- name: status of the app
  shell: echo "Hello World"
  when: ansible_host == "db*"

What regex pattern should be used or how to use a regex here ?

Answer 1

Try db\\w+

- name: status of the app
  shell: echo "Hello World"
  when: ansible_host == "db\w+"

You can test with regex101 .
