salt.modules.postgres¶

Module to provide Postgres compatibility to salt.

configuration:

In order to connect to Postgres, certain configuration is required in /etc/salt/minion on the relevant minions. Some sample configs might look like:

postgres.host: 'localhost'
postgres.port: '5432'
postgres.user: 'postgres' -> db user
postgres.pass: ''
postgres.maintenance_db: 'postgres'

The default for the maintenance_db is 'postgres' and in most cases it can be left at the default setting. This data can also be passed into pillar. Options passed into opts will overwrite options passed into pillar

To prevent Postgres commands from running arbitrarily long, a timeout (in seconds) can be set

postgres.timeout: 60

New in version 3006.0.

note:

This module uses MD5 hashing which may not be compliant with certain security audits.

note:

When installing postgres from the official postgres repos, on certain linux distributions, either the psql or the initdb binary is not automatically placed on the path. Add a configuration to the location of the postgres bin's path to the relevant minion for this module:

postgres.bins_dir: '/usr/pgsql-9.5/bin/'
