Certificate Management for Admin REST API Endpoints
|
|
===================================================
|
|
|
|
All messaging between SystemControllers and Subclouds in the |prod-dc|
|
|
system uses the admin REST API service endpoints, which are all configured for
|
|
secure HTTPS.
|
|
|
|
|prod| supports automated HTTPS certificate renewal for |prod-dc| admin
|
|
endpoints.

Certificates on the SystemController
|
|
------------------------------------
|
|
|
|
In a |prod-dc| system, the HTTPS certificates for admin endpoints are
|
|
managed by |prod| internally.
|
|
|
|
.. note::
|
|
All renewal operations are automatic, and no user operation is required.
|
|
|
|
For admin endpoints, the SystemControllers in a |prod-dc| system
|
|
manages the following certificates:
|
|
|
|
|
|
.. certificate-management-for-admin-rest--api-endpoints-ul-zdc-pmk-xnb:
|
|
|
|
- **DC-AdminEp-Root-CA certificate**: This certificate expires in 1825 days
|
|
\(approximately 5 years\). Renewal of this certificate starts 30 days prior
|
|
to expiry.
|
|
|
|
The Root |CA| certificate is renewed on the SystemController. When the
|
|
certificate is renewed, |prod| renews the intermediate |CA|
|
|
certificates for all subclouds.
|
|
|
|
- **DC-AdminEp-Intermediate-CA certificate for 'each' subcloud**: This
|
|
certificate expires in 365 days. Renewal of this certificate starts 30 days
|
|
prior to expiry. This certificate is used for all subclouds that are
|
|
unmanaged.
|
|
|
|
- **DC-AdminEp-endpoint**: This certificate expires in 180 days. Renewal of
|
|
this certificate starts 30 days prior to expiry.

Certificates on the Subcloud
|
|
----------------------------
|
|
|
|
For admin endpoints, the subcloud controllers manage the following
|
|
certificates:
|
|
|
|
|
|
.. certificate-management-for-admin-rest--api-endpoints-ul-x51-3qk-xnb:
|
|
|
|
- **DC-AdminEp-Intermediate-CA certificate**: The intermediate CA certificate
|
|
for a subcloud is renewed on the SystemController. It is sent to the
|
|
subcloud using a Rest API. Therefore, a subcloud needs to be online to
|
|
receive the renewed certificate.
|
|
|
|
If the subcloud is offline at the time when the subcloud intermediate |CA|
|
|
certificate is renewed, the subcloud status **dc-cert** displays
|
|
"out-of-sync". Certificate renewal continues once the subcloud is online.
|
|
When renewal completes, the status changes to "in-sync". Subclouds start
|
|
admin endpoint certificate renewal once subcloud intermediate |CA|
|
|
certificate renewal is complete.
|
|
|
|
- **DC-AdminEp certificate for the Subcloud**: This certificate expires in
|
|
180 days. Renewal of this certificate starts 30 days prior to expiry.
|
|
|
|
When the admin endpoint certificate is renewed, a new |TLS| certificate is
|
|
generated. The new |TLS| certificate is used to provide |TLS| termination.
|
|
|
|
|
|
The SystemController audits subcloud AdminEp certificates daily. It also audits
|
|
subcloud admin endpoints when a subcloud becomes online or managed. If the
|
|
subcloud admin endpoint is "out-of-sync", the SystemController initiates
|
|
intermediate |CA| certificate renewal, to force subcloud renewal of the admin
|
|
endpoint certificate.
