View Pillar Data:

# salt ' * ' Pillar.items

The default root directory for pillar in:/srv/pillar, you can change the configuration file/etc/salt/master with the following parameters:

Pillar_roots:your_dir

Build the following pillar root directory and create the Portal file: Top.sls

# mkdir/srv/pillar# Vi/srv/pillar/top.sls

Top.sls:

Base:  ' * ':    -Data

The above entry file specifies the/srv/pillar/data.sls file, which applies to all minions. (‘*‘).

Data.sls:

Info:somedata

Refresh the pillar of all nodes:

# salt ' * ' saltutil.refresh_pillar

202:
True
203:

Look at the pillar of the node again:

# salt ' * ' Pillar.items

202:
----------

If you create a subdirectory users/below/srv/pillar/, you can refer directly to Init.sls in Top.sls. For example:

# mkdir/srv/pillar/users# Vi/srv/pillar/users/init.sls

Init.sls content is as follows:

Users:  jhonson:2001  tom:2993  peter:3098  tex:18990

In order to be able to refer to users in Top.sls, you need to change to:

Base:  ' * ':    -Data    -users

Refresh and display:

# salt ' * ' saltutil.refresh_pillar# salt ' * ' Pillar.item users

203:

One more example:

# mkdir/srv/pillar/hadoop# Vi/srv/pillar/hadoop/params.sls

Params.sls:

HDFs:  namenode:192.168.122.201  stadbynode:192.168.122.202hbase:  master:192.168.122.201

# Vi/srv/pillar/top.sls

Top.sls:

Base:  ' * ':    -Data    -users    -Hadoop.params

Test using:

# salt ' * ' saltutil.refresh_pillar# salt ' * ' Pillar.items
