The Open Service Broker API specification allows for extensions and variations based on the environments in which it is being used; this document contains the suggested usage pattern for some of those variants.
While use of this profile is OPTIONAL, an implementation is not compliant with this profile if it fails to satisfy one or more of the MUST, SHALL or REQUIRED level requirements defined herein.
- Notations and Terminology
- Originating Identity Header
- Context Object
- Bind Resource Object
- Service Metadata
- Catalog Extensions
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119.
Please refer to terminology defined by the Open Service Broker API specification.
In the Open Service Broker API specification it defines an additional HTTP Header that can be included in messages from the Platform to identify the user that requested the action to be taken.
The header consists of two parts: a platform
string and value
string,
where the value
is a Base64 encoded serialized JSON object.
Both parts will vary based on the Platform which is being used. The
following sections define the values to be used based on the Platform
and which properties are expected to appear in the value
JSON.
Note that when both the originating identity HTTP Header and the Context
object appear in the same message the platform
value MUST be the same
for both.
platform
Value: cloudfoundry
The following properties MUST appear within the JSON encoded value
:
Property | Type | Description |
---|---|---|
user_id | string | The user_id value from the Cloud Foundry JWT token. |
Platforms MAY include additional properties.
For example, a value
of:
{
"user_id": "683ea748-3092-4ff4-b656-39cacc4d5360"
}
would appear in the HTTP Header as:
X-Broker-API-Originating-Identity: cloudfoundry eyANCiAgInVzZXJfaWQiOiAiNjgzZWE3NDgtMzA5Mi00ZmY0LWI2NTYtMzljYWNjNGQ1MzYwIg0KfQ==
platform
Value: kubernetes
The following properties MUST appear within the JSON encoded value
:
Property | Type | Description |
---|---|---|
username | string | The username property from the Kubenernetes user.info object. |
uid | string | The uid property from the Kubenernetes user.info object. |
groups | array-of-strings | The groups property from the Kubenernetes user.info object. |
extra | map-of-array-of-strings | The extra property from the Kubernetes user.info object. |
Platforms MAY include additional properties.
For example, a value
of:
{
"username": "duke",
"uid": "c2dde242-5ce4-11e7-988c-000c2946f14f",
"groups": [ "admin", "dev" ],
"extra": {
"mydata": [ "data1", "data3" ]
}
}
would appear in the HTTP Header as:
X-Broker-API-Originating-Identity: kubernetes ew0KICAidXNlcm5hbWUiOiAiZHVrZSIsDQogICJ1aWQiOiAiYzJkZGUyNDItNWNlNC0xMWU3LTk4OGMtMDAwYzI5NDZmMTRmIiwNCiAgImdyb3VwcyI6IFsgImFkbWluIiwgImRldiIgXSwNCiAgImV4dHJhIjogew0KICAgICJteWRhdGEiOiBbICJkYXRhMSIsICJkYXRhMyIgXQ0KICB9DQp9
In the Open Service Broker API specification there are certain
message flows that include a context
property. This property is defined
as an opaque JSON object that is meant to contain contextual information
about the environment in which the Platform or Application is executing.
While the context
property is defined as an opaque JSON object, in practice,
it is often useful and necessary for there to be an agreed upon set of
properties to ensure a common understanding of this data between the
Platform and the Service Brokers.
The list of properties within the Context Object can vary depending on which Service Broker API is being invoked and which Platform is being used. This section will define a set of properties for each Platform and specify when each is meant to be used. Platforms MAY choose to provide additional properties beyond the ones defined in this document.
Each property will include the version of the Open Service Broker API in which it was introduced. For any API call in which that property is mandatory, it is only mandatory for the specified version of the specification or higher.
Aside from the Platform specific properties, defined in the following
sections, there is one common property called platform
that
MUST also appear within context
to indicate which Platform is being used.
The platform
property MUST be a string
and serialized as follows:
"platform": "platform-string-here"
Each section below will define the platform
value that MUST be used based
on the Platform and the set of additional properties that MUST be present.
Note that when both the originating identity HTTP Header and the Context
object appear in the same message the platform
value MUST be the same
for both.
To enable support for Platforms to send an update request for a Service Instance
containing only contextual data, a Service Broker MUST declare support by
including "allow_context_updates": true
in its
catalog endpoint.

The unique identifier for the Kubernetes cluster from which the request was sent. This property can be useful when a Service Broker tries to call back to a Platform that is managing multiple Kubernetes clusters. Typically this value will be static for the lifetime of the cluster, however, that is a Platform implementation choice. Brokers ought to take care that, while atypical, it is possible for the value to change over time.
This property MUST be a non-empty string serialized as follows:

This OPTIONAL property holds an object with the annotations key/value pairs. If present, this property MUST be an object, with zero or more properties as follows:
"app_annotations": { "prefix-here.org/name-here":"value-here" }
For example:

}
While the specification does not mandate the property names used
in the metadata
objects, it is RECOMMENDED that the following names
be used when possible in an attempt to provide some degree of interoperability
and consistency.
Service Broker API Field | Type | Description |
---|---|---|
metadata.displayName | string | The name of the service to be displayed in graphical clients. |
metadata.imageUrl | string | The URL to an image or a data URL containing an image. |
metadata.longDescription | string | Long description. |

metadata.bullets | array-of-strings | Features of this plan, to be displayed in a bulleted-list. |
metadata.costs | array-of-objects | An array-of-objects that describes the costs of a service, in what currency, and the unit of measure. If there are multiple costs, all of them could be billed to the user (such as a monthly + usage costs at once). |
metadata.displayName | string | Name of the plan to be displayed to clients. |
This object describes the costs of a service, in what currency, and the unit of measure.

For example:
"costs": [
{
"amount": {
"usd": 649.0
},
"unit": "MONTHLY"
}
]
The example below contains a catalog of one service, having one Service Plan. Of course, a Service Broker can offer a catalog of many services, each having many plans.

In addition to the metadata described in Service Metadata, Service Brokers MAY also expose the following fields to enable Cloud Foundry specific behaviour.
