saltstack pillar与ansible 变量
saltstack pillar与ansible 变量需求，由不同主机，生成不同的配置项目。
1、在ansible中如果要实现配置文件的参数替换，只需要在inventory中配置,并使用{{}}在template中引用变量即可
示例：
1
2
3
4
5
6
7
had5 port=111var1=1
had6 port=222var1=2
vi templates/test.conf.j2
port = {{ port }}
var = {{ var1 }}
生成的配置文件内容如下:
1
2
3
4
5
6
7
8
# ansible all -i hosts -m shell -a "cat /tmp/test.conf"
had5 | success | rc=0 >>
port = 111
var = 1
had6 | success | rc=0 >>
port = 222
var = 2
2、在slatstack，要实现上述需求，需要借助pillar与grains。
先看pillar的配置：

# tree /srv/pillar/vartest/
/srv/pillar/vartest/
└── init.sls
0 directories, 1 file
# cat /srv/pillar/top.sls
base:
'*':
- vartest
# cat /srv/pillar/vartest/init.sls
vartest:
conn: 100
{% if grains['id'] == 'had5.com' %}
port: 111
var1: 1
{% elif grains['id'] == 'had6.com' %}
port: 222
var1: 2
{% else %}
port: 888
var1: 8
{% endif %}
我们是通过 grains来指定特定主机的变量参数值。

salt还是要复杂一些的。
