Happy:
今日iT邦主動幫我昇升至 iT邦新手 第 4 級！真是一個全方位的技術網站
ansible 加上條件判斷:

- hosts: web5
  name: play-test

  vars:
    seq:
      - 1
      - 2
      - 3  
      - 4
  tasks:
    - name: debug test
      debug:
        msg: "{{item}}"        #單循環   
      with_items: "{{ seq }}"  #單循環  
      when: item >= 3          #當項目>=3         

跑出來如以下:(大等於3才會印出來)
