I want to select data from a database table (here mysql) with saltstack. In my test scenario I have a linux host called salt-master. On this host the database, the master and the minion are running.
My target is to select the data with the minion, but this does not work in my environment.
1) You see the data in the table. The data itself are of no relevance for the scenario.
MariaDB [salt]> SELECT minion_id,qmgr,object_type,value from mqobjects;
+--------------+-------+-------------+-------+
| minion_id | qmgr | object_type | value |
+--------------+-------+-------------+-------+
| salt-minion2 | QM200 | port | 14200 |
| salt-minion2 | QM201 | port | 14201 |
| salt-minion2 | QM201 | port | 15201 |
| salt-minion2 | QM201 | qlocal | QL1 |
| salt-minion2 | QM201 | qlocal | QL2 |
| salt-minion3 | QM301 | port | 14300 |
| salt-minion3 | QM301 | port | 14301 |
| salt-minion3 | QM302 | port | 14302 |
+--------------+-------+-------------+-------+
8 rows in set (0.00 sec)
2) Using the execution module mysql with the runner gives me the results I want to have.
salt-master:/srv/salt # salt-run salt.cmd mysql.query salt "SELECT minion_id,qmgr,object_type,value from mqobjects"
columns:
- minion_id
- qmgr
- object_type
- value

salt-master:/srv/salt #
3) Doing the same with the minion does not cause an error, but does not give any result either. Why?
salt-master:/srv/salt # salt salt-master mysql.query salt "SELECT minion_id,qmgr,object_type,value from mqobjects"
salt-master:
----------
salt-master:/srv/salt #
4) I also tried it with a sls file.
a) With check if db exists
salt-master:/srv/salt # cat cmdb/MqObjects2Grains.sls
queryMqObjects:
mysql_query.run:
- name: salt
- database: mysql
- query: "SELECT minion_id,qmgr,object_type,value from mqobjects"
- check_db_exists: True
salt-master:/srv/salt # salt salt-master state.apply cmdb.MqObjects2Grains
salt-master:

salt-master:/srv/salt # cat cmdb/MqObjects2Grains.sls

Can anybody give me some hints, what I am doing wrong? That would be great!
