Note

There are three PostgreSQL returners. Any can function as an external master job cache. but each has different features. SaltStack recommends returners.pgjsonb if you are working with a version of PostgreSQL that has the appropriate native binary JSON types. Otherwise, review returners.postgres and returners.postgres_local_cache to see which module best suits your particular needs.

To enable this returner, the minion will need the python client for PostgreSQL installed and the following values configured in the minion or master config. These are the defaults:

returner.pgjsonb.host: 'salt'
returner.pgjsonb.user: 'salt'
returner.pgjsonb.pass: 'salt'
returner.pgjsonb.db: 'salt'
returner.pgjsonb.port: 5432

SSL is optional. The defaults are set to None. If you do not want to use SSL, either exclude these options or set them to None.

returner.pgjsonb.sslmode: None
returner.pgjsonb.sslcert: None
returner.pgjsonb.sslkey: None
returner.pgjsonb.sslrootcert: None
returner.pgjsonb.sslcrl: None

New in version 2017.5.0.

Alternative configuration values can be used by prefacing the configuration with alternative.. Any values not found in the alternative configuration will be pulled from the default location. As stated above, SSL configuration is optional. The following ssl options are simply for illustration purposes:

alternative.pgjsonb.host: 'salt'
alternative.pgjsonb.user: 'salt'
alternative.pgjsonb.pass: 'salt'
alternative.pgjsonb.db: 'salt'
alternative.pgjsonb.port: 5432
alternative.pgjsonb.ssl_ca: '/etc/pki/mysql/certs/localhost.pem'
alternative.pgjsonb.ssl_cert: '/etc/pki/mysql/certs/localhost.crt'
alternative.pgjsonb.ssl_key: '/etc/pki/mysql/certs/localhost.key'

Use the following Pg database schema:

CREATE DATABASE  salt
  WITH ENCODING 'utf-8';

--
-- Table structure for table `jids`
--
DROP TABLE IF EXISTS jids;
CREATE TABLE jids (
   jid varchar(255) NOT NULL primary key,
   load jsonb NOT NULL
);
CREATE INDEX idx_jids_jsonb on jids
       USING gin (load)
       WITH (fastupdate=on);

--
-- Table structure for table `salt_returns`
--

DROP TABLE IF EXISTS salt_returns;
CREATE TABLE salt_returns (
  fun varchar(50) NOT NULL,
  jid varchar(255) NOT NULL,
  return jsonb NOT NULL,
  id varchar(255) NOT NULL,
  success varchar(10) NOT NULL,
  full_ret jsonb NOT NULL,
  alter_time TIMESTAMP WITH TIME ZONE DEFAULT NOW());

CREATE INDEX idx_salt_returns_id ON salt_returns (id);
CREATE INDEX idx_salt_returns_jid ON salt_returns (jid);
CREATE INDEX idx_salt_returns_fun ON salt_returns (fun);
CREATE INDEX idx_salt_returns_return ON salt_returns
    USING gin (return) with (fastupdate=on);
CREATE INDEX idx_salt_returns_full_ret ON salt_returns
    USING gin (full_ret) with (fastupdate=on);

--
-- Table structure for table `salt_events`
--

DROP TABLE IF EXISTS salt_events;
DROP SEQUENCE IF EXISTS seq_salt_events_id;
CREATE SEQUENCE seq_salt_events_id;
CREATE TABLE salt_events (
    id BIGINT NOT NULL UNIQUE DEFAULT nextval('seq_salt_events_id'),
    tag varchar(255) NOT NULL,
    data jsonb NOT NULL,
    alter_time TIMESTAMP WITH TIME ZONE DEFAULT NOW(),
    master_id varchar(255) NOT NULL);

CREATE INDEX idx_salt_events_tag on
    salt_events (tag);
CREATE INDEX idx_salt_events_data ON salt_events
    USING gin (data) with (fastupdate=on);

Required python modules: Psycopg2

To use this returner, append '--return pgjsonb' to the salt command.

salt '*' test.ping --return pgjsonb

To use the alternative configuration, append '--return_config alternative' to the salt command.

New in version 2015.5.0.

salt '*' test.ping --return pgjsonb --return_config alternative

To override individual configuration items, append --return_kwargs '{"key:": "value"}' to the salt command.

New in version 2016.3.0.

salt '*' test.ping --return pgjsonb --return_kwargs '{"db": "another-salt"}'
salt.returners.pgjsonb.event_return(events)

Return event to Pg server

Requires that configuration be enabled via 'event_return' option in master config.

salt.returners.pgjsonb.get_fun(fun)

Return a dict of the last function called for all minions

salt.returners.pgjsonb.get_jid(jid)

Return the information returned when the specified job id was executed

salt.returners.pgjsonb.get_jids()

Return a list of all job ids

salt.returners.pgjsonb.get_load(jid)

Return the load data that marks a specified jid

salt.returners.pgjsonb.get_minions()

Return a list of minions

salt.returners.pgjsonb.prep_jid(nocache=False, passed_jid=None)

Do any work necessary to prepare a JID, including sending a custom id

salt.returners.pgjsonb.returner(ret)

Return data to a Pg server

salt.returners.pgjsonb.save_load(jid, load, minions=None)

Save the load to the specified jid id
