# Docker Registry v2 authentication using OAuth2
|
||||
|
||||
This document describes support for the OAuth2 protocol within the authorization
|
||||
server. [RFC6749](https://tools.ietf.org/html/rfc6749) should be used as a
|
||||
reference for the protocol and HTTP endpoints described here.
|
||||
|
||||
## Refresh token format
|
||||
|
||||
The format of the refresh token is completely opaque to the client and should be
|
||||
determined by the authorization server. The authorization should ensure the
|
||||
token is sufficiently long and is responsible for storing any information about
|
||||
long-lived tokens which may be needed for revoking. Any information stored
|
||||
inside the token will not be extracted and presented by clients.
|
||||
|
||||
## Getting a token
|
||||
|
||||
POST /token
|
||||
|
||||
#### Headers
|
||||
Authorization headers
|
||||
Content-Type: application/x-www-form-urlencoded
|
||||
|
||||
#### Post parameters
|
||||
|
||||
<dl>
|
||||
<dt>
|
||||
<code>grant_type</code>
|
||||
</dt>
|
||||
<dd>
|
||||
(REQUIRED) Type of grant used to get token. When getting a refresh token
|
||||
using credentials this type should be set to "password" and have the
|
||||
accompanying basic auth header. Type "authorization_code" is reserved
|
||||
for future use for authenticating to an authorization server without
|
||||
having to send credentials directly from the client. When requesting an
|
||||
access token with a refresh token this should be set to "refresh_token".
|
||||
</dd>
|
||||
<dt>
|
||||
<code>service</code>
|
||||
</dt>
|
||||
<dd>
|
||||
(REQUIRED) The name of the service which hosts the resource to get
|
||||
access for. Refresh tokens will only be good for getting tokens for
|
||||
this service.
|
||||
</dd>
|
||||
<dt>
|
||||
<code>client</code>
|
||||
</dt>
|
||||
<dd>
|
||||
(REQUIRED) The name of the client which is getting accessed. Intended to be human
|
||||
readable for key auditing.
|
||||
</dd>
|
||||
<dt>
|
||||
<code>access_type</code>
|
||||
</dt>
|
||||
<dd>
|
||||
(OPTIONAL) Access which is being requested. If "offline" is provided then a refresh
|
||||
token will be returned. Otherwise only a short lived access token will
|
||||
be returned. If the grant type is "refresh_token" this will only return
|
||||
the same refresh token and not a new one.
|
||||
</dd>
|
||||
<dt>
|
||||
<code>scope</code>
|
||||
</dt>
|
||||
<dd>
|
||||
(OPTIONAL) The resource in question, formatted as one of the space-delimited
|
||||
entries from the <code>scope</code> parameters from the <code>WWW-Authenticate</code> header
|
||||
shown above. This query parameter should be specified multiple times if
|
||||
there is more than one <code>scope</code> entry from the <code>WWW-Authenticate</code>
|
||||
header. The above example would be specified as:
|
||||
<code>scope=repository:samalba/my-app:push</code>. When requesting a refresh
|
||||
token the scopes may be empty since the refresh token will not be limited by
|
||||
this scope, only the provided short lived access token.
|
||||
</dd>
|
||||
<dt>
|
||||
<code>refresh_token</code>
|
||||
</dt>
|
||||
<dd>
|
||||
(OPTIONAL) The refresh token to use for authentication when grant type "refresh_token" is used.
|
||||
</dd>
|
||||
</dl>
