Remove references to OpenStack Anchor
The OpenStack Anchor project is now officially retired[1]. This patch removes the references to Anchor from Octavia. These old references were confusing new users. [1] https://review.opendev.org/#/c/611187/ Change-Id: Idfe90aa69b497e8270118174dde00567d7fab4ab

Anchor
|

======
|
||||
Anchor (see https://wiki.openstack.org/wiki/Security/Projects/Anchor) is
|
||||
an ephemeral PKI system built to enable cryptographic trust in OpenStack
|
||||
services. In the context of Octavia it can be used to sign the certificates
|
||||
which secure the amphora - controller communication.
|
||||
|
||||
Basic Setup
|
||||
-----------
|
||||
1. Download/Install/Start Anchor from https://github.com/openstack/anchor
|
||||
2. Change the listening port in config.py to 9999
|
||||
3. I found it useful to run anchor in an additional devstack screen
|
||||
4. Set in octavia.conf (root-ca.crt here is the Anchor CA)
|
||||
|
||||
a. [controller_worker] cert_generator = anchor
|
||||
b. [haproxy_amphora] server_ca = /opt/stack/anchor/CA/root-ca.crt
|
||||
|
||||
5. Restart o-cw o-hm o-hk
|
||||
|
||||
Benefit
|
||||
-------
|
||||
In bigger cloud installations Anchor can be a gateway to a more secure
|
||||
certificate management system than our default local signing.

Rotating Amphora Certificates
|
||||
-----------------------------
|
||||
|
||||
For the server part Octavia will either act as a certificate authority itself,
|
||||
or use :doc:`../Anchor` to issue amphora certificates to be used
|
||||
by each amphora. Octavia will also monitor those certificates and refresh them
|
||||
before they expire.
