postgresql_privs – Grant or revoke privileges on PostgreSQL database objects
Synopsis
- Grant or revoke privileges on PostgreSQL database objects.
- This module is basically a wrapper around most of the functionality of PostgreSQL’s GRANT and REVOKE statements with detection of changes (GRANT/REVOKE privs ON type objs TO/FROM roles).
Requirements
The below requirements are needed on the host that executes this module.
- psycopg2
Parameters
Parameter | Choices/Defaults | Comments |
---|---|---|
ca_cert string added in 2.3 | Specifies the name of a file containing SSL certificate authority (CA) certificate(s). If the file exists, the server's certificate will be verified to be signed by one of these authorities. aliases: ssl_rootcert | |
database string / required | Name of database to connect to. aliases: db, login_db | |
fail_on_role boolean added in 2.8 |
| If yes , fail when target role (for whom privs need to be granted) does not exist. Otherwise just warn and continue. |
grant_option boolean |
| Whether role may grant/revoke the specified privileges/group memberships to others.Set to no to revoke GRANT OPTION, leave unspecified to make no changes.
grant_option only has an effect if state is present .aliases: admin_option |
host string | Database host address. If unspecified, connect via Unix socket. aliases: login_host | |
login string | Default: "postgres" | The username to authenticate with. aliases: login_user |
login_host string | Host running the database. | |
login_password string | The password used to authenticate with. | |
login_unix_socket string | Path to a Unix domain socket for local connections. | |
login_user string | Default: "postgres" | The username used to authenticate with. |
objs string | Comma separated list of database objects to set privileges on. If type is table , partition table , sequence or function , the special valueALL_IN_SCHEMA can be provided instead to specify all database objects of type type in the schema specified via schema. (This also works with PostgreSQL < 9.0.) (ALL_IN_SCHEMA is available for function and partition table from version 2.8)If type is database , this parameter can be omitted, in which case privileges are set for the database specified via database.If type is function, colons (":") in object names will be replaced with commas (needed to specify function signatures, see examples) aliases: obj | |
password string | The password to authenticate with. aliases: login_password | |
port integer | Default: 5432 | Database port to connect to. aliases: login_port |
privs string | Comma separated list of privileges to grant/revoke. aliases: priv | |
roles string / required | Comma separated list of role (user/group) names to set permissions for. The special value PUBLIC can be provided instead to set permissions for the implicitly defined PUBLIC group.aliases: role | |
schema string | Schema that contains the database objects specified via objs. May only be provided if type is table , sequence , function or default_privs . Defaults to public in these cases. | |
session_role string added in 2.8 | Switch to session_role after connecting. The specified session_role must be a role that the current login_user is a member of. Permissions checking for SQL commands is carried out as though the session_role were the one that had logged in originally. | |
ssl_mode string added in 2.3 |
| Determines whether or with what priority a secure SSL TCP/IP connection will be negotiated with the server. See https://www.postgresql.org/docs/current/static/libpq-ssl.html for more information on the modes. Default of prefer matches libpq default. |
state string |
| If present , the specified privileges are granted, if absent they are revoked. |
target_roles string added in 2.8 | A list of existing role (user/group) names to set as the default permissions for database objects subsequently created by them. Parameter target_roles is only available with type=default_privs . | |
type string |
| Type of database object to set privileges on. The `default_privs` choice is available starting at version 2.7. The 'foreign_data_wrapper' and 'foreign_server' object types are available from Ansible version '2.8'. |
unix_socket string | Path to a Unix domain socket for local connections. aliases: login_unix_socket |
Notes
Note
- Default authentication assumes that postgresql_privs is run by the
postgres
user on the remote host. (Ansible’suser
orsudo-user
). - This module requires Python package psycopg2 to be installed on the remote host. In the default case of the remote host also being the PostgreSQL server, PostgreSQL has to be installed there as well, obviously. For Debian/Ubuntu-based systems, install packages postgresql and python-psycopg2.
- Parameters that accept comma separated lists (privs, objs, roles) have singular alias names (priv, obj, role).
- To revoke only
GRANT OPTION
for a specific object, set state topresent
and grant_option tono
(see examples). - Note that when revoking privileges from a role R, this role may still have access via privileges granted to any role R is a member of including
PUBLIC
. - Note that when revoking privileges from a role R, you do so as the user specified via login. If R has been granted the same privileges by another user also, R can still access database objects via these privileges.
- When revoking privileges,
RESTRICT
is assumed (see PostgreSQL docs). - The ca_cert parameter requires at least Postgres version 8.4 and psycopg2 version 2.4.3.
- The default authentication assumes that you are either logging in as or sudo’ing to the
postgres
account on the host. - This module uses psycopg2, a Python PostgreSQL database adapter. You must ensure that psycopg2 is installed on the host before using this module. If the remote host is the PostgreSQL server (which is the default case), then PostgreSQL must also be installed on the remote host. For Ubuntu-based systems, install the
postgresql
,libpq-dev
, andpython-psycopg2
packages on the remote host before using this module. - The ca_cert parameter requires at least Postgres version 8.4 and psycopg2 version 2.4.3.
