ansible pitfall:

the problem here is the serial: 1
- name: restart vra cluster
  hosts: vra
  tags: vra-cluster-restart
  serial: 1
  max_fail_percentage: 0
  tasks:
  - name:  test
    shell: touch /tmp/bla`date +%F%T`
    run_once: true
    delegate_to: bla.example.com

run_once does not work in conjunction with when, if execution is skipped on the first host because of the when condition it is not executed at all

#run debug stuff localy
ansible -m debug -a msg="{{ '-'.join(('str1', 'str2', 'str3')) }}" localhost

#print all vars of a server
ansible-inventory inventories/myinv --host mygroup[0] |less

regex Example:
 - name: Set fact stage
  set_fact:
