GRANT

reference

The GRANT statement allows granting any RBAC roles to a specific user.

Roles can be of the following two types:

simple: Roles which apply generically to all keyspaces or resources in the cluster.

For example: ClusterAdmin or BucketAdmin
parameterized by a keyspace: Roles which are defined for the scope of the specified keyspace only. The keyspace name is specified after ON.

For example: DataReader ON `travel-sample`
or Query_Select ON `travel-sample`

Only Full Administrators can run the GRANT statement. For more details about user roles, see Authorization.

Syntax

grant ::= 'GRANT' role ( ',' role )* ( 'ON' keyspace-ref ( ',' keyspace-ref )* )?
          'TO' user ( ',' user )*

role

One of the RBAC role names predefined by Couchbase Server.

The following roles have short forms that can be used as well:

query_select → select
query_insert → insert
query_update → update
query_delete → delete

user

A user name created by the Couchbase Server RBAC system.

Keyspace Reference

keyspace-ref ::= keyspace-path | keyspace-partial

keyspace-path ::= ( namespace ':' )? bucket ( '.' scope '.' collection )?

keyspace-partial ::= collection

The simple name or fully-qualified name of a keyspace. Refer to the CREATE INDEX statement for details of the syntax.

Usage

GRANT statements support legacy systems and have two forms:

1. Unparameterized Roles

GRANT Replication Admin, Query External Access
   TO cchaplan, jgleason;

GRANT replication_admin, query_external_access
   TO cchaplan, jgleason;

2. Parameterized Roles

GRANT Query Select, Views Admin
   ON orders, customers
   TO bill, linda;

GRANT query_select, views_admin
   ON orders, customers
   TO bill, linda;

Mixing of parameterized and unparameterized roles or syntax is not allowed and will create an error.

Examples

Example 1. Grant the role of Cluster Administrator to three people

GRANT ClusterAdmin TO david, michael, robin;

Example 2. Grant the roles of Cluster Administrator and Data Reader in the travel-sample keyspace to Debby

GRANT ClusterAdmin, DataReader ON `travel-sample` TO debby;
