模块介绍与使用
ping模块
1 [root@node1 config]# ansible k8s -m ping 2 192.168.1.3 | SUCCESS => { 3 "changed": false, 4 "ping": "pong" 5 } 6 192.168.1.2 | SUCCESS => { 7 "changed": false, 8 "ping": "pong" 9 } 10 192.168.1.1 | SUCCESS => { 11 "changed": false, 12 "ping": "pong" 13 } 14 [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
1 [root@node1 config]# ansible k8s -m command -a 'date' 2 192.168.1.1 | SUCCESS | rc=0 >> 3 2018年 01月 21日 星期日 17:09:42 CST 4 5 192.168.1.3 | SUCCESS | rc=0 >> 6 2018年 01月 21日 星期日 17:09:42 CST 7 8 192.168.1.2 | SUCCESS | rc=0 >> 9 2018年 01月 21日 星期日 17:09:42 CST
command万能模块也可以这样写
1 [root@node1 config]# ansible k8s -a 'date' 2 192.168.1.1 | SUCCESS | rc=0 >> 3 2018年 01月 21日 星期日 17:10:00 CST 4 5 192.168.1.3 | SUCCESS | rc=0 >> 6 2018年 01月 21日 星期日 17:10:00 CST 7 8 192.168.1.2 | SUCCESS | rc=0 >> 9 2018年 01月 21日 星期日 17:10:00 CST 10 11 [root@node1 config]#
shell模块支持特殊字符比如空格
1 [root@node1 config]# ansible k8s -m shell -a 'touch /tmp/ansible.txt' 2 3 192.168.1.1 | SUCCESS | rc=0 >> 4 5 6 192.168.1.3 | SUCCESS | rc=0 >> 7 8 9 192.168.1.2 | SUCCESS | rc=0 >> 10 11 12 [root@node1 config]# ansible k8s -m shell -a 'ls -l /tmp/ansible.txt' 13 192.168.1.1 | SUCCESS | rc=0 >> 14 -rw-r--r-- 1 root root 0 1月 21 17:12 /tmp/ansible.txt 15 16 192.168.1.3 | SUCCESS | rc=0 >> 17 -rw-r--r-- 1 root root 0 1月 21 17:12 /tmp/ansible.txt 18 19 192.168.1.2 | SUCCESS | rc=0 >> 20 -rw-r--r-- 1 root root 0 1月 21 17:12 /tmp/ansible.txt 21 22 [root@node1 config]#
copy模块
