|
|||
notification requests. One or more events are sent in a structure called an
|
||||
envelope. Each event has a unique id that can be used to uniquely identify incoming
|
||||
requests, if required. Along with that, an _action_ is provided with a
|
||||
_target, identifying the object mutated during the event.
|
||||
_target_, identifying the object mutated during the event.
|
||||
|
||||
The fields available in an `event` are described below.
|
||||
|
||||
Field | Type | Description
|
||||
----- | ----- | -------------
|
||||
id | string |ID provides a unique identifier for the event.
|
||||
timestamp | Time | Timestamp is the time at which the event occurred.
|
||||
action | string | Action indicates what action encompasses the provided event.
|
||||
target | distribution.Descriptor | Target uniquely describes the target of the event.
|
||||
length | int | Length in bytes of content. Same as Size field in Descriptor.
|
||||
repository | string | Repository identifies the named repository.
|
||||
fromRepository | string | FromRepository identifies the named repository which a blob was mounted from if appropriate.
|
||||
url | string | URL provides a direct link to the content.
|
||||
tag | string | Tag identifies a tag name in tag events
|
||||
request | [RequestRecord](https://godoc.org/github.com/docker/distribution/notifications#RequestRecord) | Request covers the request that generated the event.
|
||||
actor | [ActorRecord](https://godoc.org/github.com/docker/distribution/notifications#ActorRecord). | Actor specifies the agent that initiated the event. For most situations, this could be from the authorization context of the request.
|
||||
source | [SourceRecord](https://godoc.org/github.com/docker/distribution/notifications#SourceRecord) | Source identifies the registry node that generated the event. Put differently, while the actor "initiates" the event, the source "generates" it.
|
||||
|
||||
The fields available in an event are described in detail in the
|
||||
[godoc](http://godoc.org/github.com/docker/distribution/notifications#Event).
|
||||
|
||||
**TODO:** Let's break out the fields here rather than rely on the godoc.

The target struct of events which are sent when manifests and blobs are deleted
|
||||
will contain a subset of the data contained in Get and Put events. Specifically,
|
||||
only the digest and repository will be sent.
