@ -21,6 +21,87 @@ Application credentials are limited by the lifespan of the user that created
them. If the user is deleted, disabled, or loses a role assignment on a
project, the application credential is deleted.
Application credentials can have their privileges limited in two ways. First,
the owner may specify a subset of their own roles that the application
credential may assume when getting a token for a project. For example, if a
user has the ``member`` role on a project, they also have the implied role
``reader`` and can grant the application credential only the ``reader`` role
for the project:
::
"roles": [
{"name": "reader"}
]
Users also have the option of delegating more fine-grained access control to
their application credentials by using access rules. For example, to create an
application credential that is constricted to creating servers in nova, the
user can add the following access rules:
::
"access_rules": [
{
"path": "/v2.1/servers",
"method": "POST",
"service": "compute"
}
]
The ``"path"`` attribute of application credential access rules uses a wildcard
syntax to make it more flexible. For example, to create an application
credential that is constricted to listing server IP addresses, you could use
either of the following access rules:
::
"access_rules": [
{
"path": "/v2.1/servers/*/ips",
"method": "GET",
"service": "compute"
}
]
or equivalently:
::
"access_rules": [
{
"path": "/v2.1/servers/{server_id}/ips",
"method": "GET",
"service": "compute"
}
]
In both cases, a request path containing any server ID will match the access
rule. For even more flexibility, the recursive wildcard ``**`` indicates that
request paths containing any number of ``/`` will be matched. For example:
::
"access_rules": [
{
"path": "/v2.1/**",
"method": "GET",
"service": "compute"
}
]
will match any nova API for version 2.1.
An access rule created for one application credential can be re-used by providing its ID to another application credential, for example:
::
"access_rules": [
{
"id": "abcdef"
}
]
