Local Docker Registry Authentication and Authorization
|
||
=======================================================
|
||
|
||
Authentication is enabled for the local Docker registry. When logging in,
|
||
users are authenticated using their platform keystone credentials.
|
||
|
||
For example:
|
||
|
||
.. code-block:: none
|
||
|
||
$ docker login registry.local:9001 -u <keystoneUserName> -p <keystonePassword>
|
||
|
||
An authorized administrator \('admin' and 'sysinv'\) can perform any Docker
|
||
action. Regular users can only interact with their own repositories \(i.e.
|
||
registry.local:9001/<keystoneUserName>/\). Any authenticated user can pull from
|
||
the following list of public images:
|
||
|
||
.. _kubernetes-admin-tutorials-authentication-and-authorization-d383e50:
|
||
|
||
- registry.local:9001:/public/\*
|
||
|
||
- registry.local:9001:/k8s.gcr.io/pause
|
||
|
||
- registry.local:9001:/quay.io/jetstack/cert-manager-acmesolver
|
||
|
||
The **mtce** user can only pull public images, but cannot push any images.
|
||
|
||
For example, only **admin** and **testuser** accounts can push to or pull from
|
||
**registry.local:9001/testuser/busybox:latest**
|
||
|
||
.. _kubernetes-admin-tutorials-authentication-and-authorization-d383e87:

Username and Docker compatibility
|
||
---------------------------------
|
||
|
||
Repository names in Docker registry paths must be lower case. For this reason,
|
||
a keystone user must exist that consists of all lower case characters. For
|
||
example, the user **testuser** is correct in the following URL, while
|
||
**testUser** would result in an error:
|
||
|
||
**registry.local:9001/testuser/busybox:latest**
|
||
|
||
.. note::
|
||
Use of the auto-generated self-signed certificate for the registry
|
||
certificate is not recommended. If you must do so, then from the central
|
||
cloud/systemController, access to the local registry can only be done using
|
||
registry.local:9001. registry.central:9001 will be inaccessible. Installing
|
||
a |CA|-signed certificate for the registry and the certificate of the |CA| as
|
||
an 'ssl_ca' certificate will remove this restriction.

||
