New in version 1.2.
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)
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. |
||
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. |
Note
Requires psycopg2
# 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
Note
Default authentication assumes that postgresql_privs is run by the postgres user on the remote host. (Ansible’s user or sudo-user).
Note
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.
Note
Parameters that accept comma separated lists (privs, objs, roles) have singular alias names (priv, obj, role).
Note
To revoke only GRANT OPTION for a specific object, set state to present and grant_option to no (see examples).
Note
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
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.
Note
When revoking privileges, RESTRICT is assumed (see PostgreSQL docs).
