Hello,
I'm using Ceph Squid, currently 19.2.1. I'd like to use either the
built-in ingress service or an approach with the RGW service to restrict
/admin access from public endpoints.
My setup:
Firewall (NGINX reverse proxy - TCP 443 stream passthrough only - no SSL)
|
Ingress Service (SSL Certificates applied)
|
RGW Gateways (SSL Certificates applied)
All administrative functions interact with RGW Gateways directly. Only
public flows pass through the Ingress Service.
As I understand /admin API is required for gateway and RGW
service management. I want to manage my SSL certs ideally via ceph spec
files (we have automation for that). The frontend firewall is designed to
act as a simple L3 / L4 ACL.
Is there a way to modify the Ingress service spec file to restrict /admin
access. According to GROK adding the following to the ingress spec YAML
should work, but the custom_configs section throws an error as follows.
I can't seem to find any official documentation around this. Feels like
it should be something to easily configure. How are others securing this?
Thanks.
