[Ansible]debug模塊 輸出變量值

官網
調試模塊主要是輸出變量

• var 直接打印一個指定變量的值
• msg 打印一段可以格式化的字符串

## -e 傳變量
ansible webservers -m debug -a "var=role" -e "role=web"
[root@ceph1 ~]# ansible webservers -m debug -a "var=role" -e "role=web"
ceph3 | SUCCESS => {
    "role": "web"
}

ansible webservers -m debug -a "msg='role is {{role}}'" -e "role=web"
[root@ceph1 ~]# ansible webservers -m debug -a "msg='role is {{role}}'" -e "role=web"
ceph3 | SUCCESS => {
    "msg": "role is web"
}
