updateRole
¶ Updates a user-defined role. The
updateRole
command must run on the role’s database.An update to a field completely replaces the previous field’s values. To grant or remove roles or privileges without replacing all values, use one or more of the following commands:
Warning
An update to the
privileges
orroles
array completely replaces the previous array’s values.The
updateRole
command uses the following syntax. To update a role, you must provide theprivileges
array,roles
array, or both:{ updateRole: "<role>", privileges: [ { resource: { <resource> }, actions: [ "<action>", ... ] }, ... ], roles: [ { role: "<role>", db: "<database>" } | "<role>", ... ], writeConcern: <write concern document> }
The
updateRole
command has the following fields:Field Type Description updateRole
string The name of the user-defined role role to update. privileges
array Optional. Required if you do not specify roles
array. The privileges to grant the role. An update to theprivileges
array overrides the previous array’s values. For the syntax for specifying a privilege, see theprivileges
array.roles
array Optional. Required if you do not specify privileges
array. The roles from which this role inherits privileges. An update to theroles
array overrides the previous array’s values.writeConcern
document Optional. The level of write concern for the update operation. The writeConcern
document takes the same fields as thegetLastError
command.In the
roles
field, you can specify both built-in roles and user-defined role.To specify a role that exists in the same database where
updateRole
runs, you can either specify the role with the name of the role:"readWrite"
Or you can specify the role with a document, as in:
{ role: "<role>", db: "<database>" }
To specify a role that exists in a different database, specify the role with a document.
Behavior¶
A role’s privileges apply to the database where the role is created. The
role can inherit privileges from other roles in its database. A role
created on the admin
database can include privileges that apply to all
databases or to the cluster and can inherit
privileges from roles in other databases.
Required Access¶
You must have the revokeRole
action on all databases in order to update a role.
You must have the grantRole
action on the database of each role in the roles
array
to update the array.
You must have the grantRole
action on the database of each
privilege in the privileges
array to update the array. If a privilege’s
resource spans databases, you must have grantRole
on the
admin
database. A privilege spans databases if the privilege is any of
the following:
- a collection in all databases
- all collections and all database
- the
cluster
resource
Example¶
The following is an example of the updateRole
command that
updates the myClusterwideAdmin
role on the admin
database.
While the privileges
and the
roles
arrays are both optional, at least
one of the two is required:
db.adminCommand(
{
updateRole: "myClusterwideAdmin",
privileges:
[
{
resource: { db: "", collection: "" },
actions: [ "find" , "update", "insert", "remove" ]
}
],
roles:
[
{ role: "dbAdminAnyDatabase", db: "admin" }
],
writeConcern: { w: "majority" }
}
)
To view a role’s privileges, use the rolesInfo
command.
