[root@server11 salt]# pwd
/srv/salt
[root@server11 salt]# vim test.sls
[root@server11 salt]# cat test.sls 
/mnt/testfile:
  file.append:
    {% if grains['fqdn'] == 'server12' %}
    - text: server12
    {% elif grains['fqdn'] == 'server13' %}
    - text: server13
    {% endif %}
[root@server11 salt]# salt '*' state.sls test
#查看效果：
[root@server12 minion]# cd /mnt/
[root@server12 mnt]# ls
testfile
[root@server12 mnt]# cat testfile 
server12

2.变量引用

[root@server11 salt]# cd apache/
[root@server11 apache]# pwd
/srv/salt/apache
[root@server11 apache]# ls
files  init.sls
[root@server11 apache]# vim init.sls 
#后面添加
/var/www/html/index.html:
  file.managed:
    - source: salt://apache/files/index.html
    - template: jinja
    - context:
      NAME: server12

[root@server11 apache]# vim files/index.html 
[root@server11 apache]# cat files/index.html #NAME是变量
{
   
   { NAME }}
[root@server11 apache]# salt server12 state.sls apache

#查看效果：
[root@server12 mnt]# cat /var/www/html/index.html 
server12

[root@server11 apache]# vim files/index.html 
[root@server11 apache]# cat files/index.html
{
   
   { grains['os'] }} - {
   
   { grains['fqdn'] }}
{
   
   { NAME }}
[root@server11 apache]# vim init.sls 
#更改最后一行：
      NAME: {
   
   { grains['ipv4'][-1] }}
[root@server11 apache]# salt server2 state.sls apache
