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 (on host that executes module)
- psycopg2
Options
parameter | required | default | choices | comments |
---|---|---|---|---|
database | yes | Name of database to connect to. Alias: db
| ||
grant_option | no |
| 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 .Alias: admin_option
| |
host | no | Database host address. If unspecified, connect via Unix socket. Alias: login_host
| ||
login | no | postgres | The username to authenticate with. Alias: login_user
| |
objs | no | Comma separated list of database objects to set privileges on. If type is table or sequence , the special value ALL_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.)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) Alias: obj
| ||
password | no | The password to authenticate with. Alias: login_password) | ||
port | no | 5432 | Database port to connect to. | |
privs | no | Comma separated list of privileges to grant/revoke. Alias: priv
| ||
roles | yes | 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.Alias: role
| ||
schema | no | Schema that contains the database objects specified via objs. May only be provided if type is table , sequence or function . Defaults to public in these cases. | ||
ssl_mode (added in 2.3)
| no | prefer |
| 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. |
ssl_rootcert (added in 2.3)
| no | 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. | ||
state | no | present |
| If present , the specified privileges are granted, if absent they are revoked. |
type | no | table |
| Type of database object to set privileges on. |
unix_socket | no | Path to a Unix domain socket for local connections. Alias: login_unix_socket
|
Examples
# On database "library": # GRANT SELECT, INSERT, UPDATE ON TABLE public.books, public.authors # TO librarian, reader WITH GRANT OPTION - postgresql_privs: database: library state: present privs: SELECT,INSERT,UPDATE type: table objs: books,authors schema: public roles: librarian,reader grant_option: yes # Same as above leveraging default values: - postgresql_privs: db: library privs: SELECT,INSERT,UPDATE objs: books,authors roles: librarian,reader grant_option: yes # REVOKE GRANT OPTION FOR INSERT ON TABLE books FROM reader # Note that role "reader" will be *granted* INSERT privilege itself if this # isn't already the case (since state: present). - postgresql_privs: db: library state: present priv: INSERT obj: books role: reader grant_option: no # REVOKE INSERT, UPDATE ON ALL TABLES IN SCHEMA public FROM reader # "public" is the default schema. This also works for PostgreSQL 8.x. - postgresql_privs: db: library state: absent privs: INSERT,UPDATE objs: ALL_IN_SCHEMA role: reader # GRANT ALL PRIVILEGES ON SCHEMA public, math TO librarian - postgresql_privs: db: library privs: ALL type: schema objs: public,math role: librarian # GRANT ALL PRIVILEGES ON FUNCTION math.add(int, int) TO librarian, reader # Note the separation of arguments with colons. - postgresql_privs: db: library privs: ALL type: function obj: add(int:int) schema: math roles: librarian,reader # GRANT librarian, reader TO alice, bob WITH ADMIN OPTION # Note that group role memberships apply cluster-wide and therefore are not # restricted to database "library" here. - postgresql_privs: db: library type: group objs: librarian,reader roles: alice,bob admin_option: yes # GRANT ALL PRIVILEGES ON DATABASE library TO librarian # Note that here "db: postgres" specifies the database to connect to, not the # database to grant privileges on (which is specified via the "objs" param) - postgresql_privs: db: postgres privs: ALL type: database obj: library role: librarian # GRANT ALL PRIVILEGES ON DATABASE library TO librarian # If objs is omitted for type "database", it defaults to the database # to which the connection is established - postgresql_privs: db: library privs: ALL type: database role: librarian
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 ssl_rootcert parameter requires at least Postgres version 8.4 and psycopg2 version 2.4.3.
Status
