模块介绍与使用

ping模块

 [root@node1 config]# ansible k8s -m ping
 192.168.1.3 | SUCCESS => {
     "changed": false,
     "ping": "pong"
 }
 192.168.1.2 | SUCCESS => {
     "changed": false,
     "ping": "pong"
 }
 192.168.1.1 | SUCCESS => {
     "changed": false,
     "ping": "pong"
 }
 [root@node1 config]# 

command模块和shell

shell和command的区别：shell模块可以特殊字符，而command是不支持

 [root@node1 config]# ansible k8s -m command -a 'date'
 192.168.1.1 | SUCCESS | rc= >>
 2018年 01月 21日 星期日 :: CST
 
 192.168.1.3 | SUCCESS | rc= >>
 2018年 01月 21日 星期日 :: CST
 
 192.168.1.2 | SUCCESS | rc= >>
 2018年 01月 21日 星期日 :: CST

command万能模块也可以这样写

 [root@node1 config]# ansible k8s -a 'date'
 192.168.1.1 | SUCCESS | rc= >>
 2018年 01月 21日 星期日 :: CST
 
 192.168.1.3 | SUCCESS | rc= >>
 2018年 01月 21日 星期日 :: CST
 
 192.168.1.2 | SUCCESS | rc= >>
 2018年 01月 21日 星期日 :: CST
 
 [root@node1 config]# 

shell模块支持特殊字符比如空格

 [root@node1 config]# ansible k8s -m shell -a 'touch /tmp/ansible.txt'
 
 192.168.1.1 | SUCCESS | rc= >>
 
 192.168.1.3 | SUCCESS | rc= >>
 
 192.168.1.2 | SUCCESS | rc= >>
 
 [root@node1 config]# ansible k8s -m shell -a 'ls -l /tmp/ansible.txt'
 192.168.1.1 | SUCCESS | rc= >>
 -rw-r--r--  root root  1月   : /tmp/ansible.txt
 
 192.168.1.3 | SUCCESS | rc= >>
 -rw-r--r--  root root  1月   : /tmp/ansible.txt
 
 192.168.1.2 | SUCCESS | rc= >>
 -rw-r--r--  root root  1月   : /tmp/ansible.txt
 
 [root@node1 config]# 

 copy模块

把本地的文件拷贝到远程机器上去

 

 [root@node1 tmp]# ansible k8s -m copy -a 'src=/tmp/ahahaa dest=/tmp/'
 192.168.1.3 | SUCCESS => {
