WalkthroughAdds Proxy to the fake client's status subresources, registers watches for configv1.Network and configv1.Infrastructure in the proxy controller, adjusts reconcile dispatch/logging for cluster-scoped requests, and adds tests verifying Proxy.Status.NoProxy updates and error handling.

@danwinship @tssurya @kyrtapz @pliurh looking for someone to check on this. it's been sitting idle on my open bug list for a while now. haven't really followed up to find a reviewer yet. I've verified the fix manually and passed this through coderabbit review (locally). should be good for a human to look now. |

This should require a change to Reconcile() too shouldn't it? (It checks what kind of object it's reconciling.)
Assuming that's correct, that means this patch doesn't actually work at all, which makes me feel like it probably ought to have had a corresponding e2e test?

Thanks @danwinship . I tested this fix with a live cluster so I am pretty confident in the change, but obviously don't know this code base like you do.
But, I think it works because Reconcile() is interested in the "Name" which I guess always will be "cluster" for these.
I think an e2e might be complicated, but if you need one figured out to validate this even further, I try to figure it out.

huh... you should fix Reconcile so that the switch does something that actually looks like it should work, rather than than something that just coincidentally happens to work. Possibly just split out the "configmap" and "not a configmap" cases.

ok, I think I see what you mean. I gave it another try to hopefully make it a little more clear

- Line 117: The log call using log.Println in the proxyconfig controller (the
line that currently reads "Ignoring unknown cluster-scoped object,
reconciliation will be skipped", "request", request) should be changed to use
log.Printf with a format specifier so the request is rendered correctly; update
the logging in the reconcile/controller function where that log.Println appears
(reference the log.Println call) to something like log.Printf("Ignoring unknown
cluster-scoped object, reconciliation will be skipped: request=%v", request) so
the request value is formatted into the message.

The proxyconfig controller reads Network.Status.ClusterNetwork and Infrastructure.Status to compute Proxy.Status.NoProxy, but only watched Proxy and ConfigMaps. Network or Infrastructure changes would not trigger reconciliation, leaving proxy status stale. Add watches for Network and Infrastructure resources to ensure reconciliation occurs when these resources change. Also add Proxy status subresource support to fake client and unit tests covering reconciliation logic.
