We currently have UDS as the configuration with GRPC.
Some users are setting up egress to remote konnectivity servers.
Cannot use UDS for this configuration.
Should have a config setup which validates the mTLS configuration.
Fixed lint errors from shell check.
Fix volumes to not include pki for ANP in grpc mode.
* fix: 81134: fix unsafe json for ReleaseControllerRevision
1. Ensures that ReleaseControllerRevision returns a proper json by
marshalling an object into bytes. Otherwise, it returns an error.
2. Also, refactors the code to commonize the merge type
GenerateDeleteOwnerRefStrategicMergeBytes that returns a byte and is
used across ReleasePod, ReleaseControllerRevison
ReleaseReplicaSet.
* Move GeneratePatchBytesForDelete to controller_ref_manager
Filter the allEndpoints list into readyEndpoints sooner, and set
"hasEndpoints" based (mostly) on readyEndpoints, not allEndpoints (so
that, eg, we correctly generate REJECT rules for services with no
_functioning_ endpoints, even if they have unusable terminating
endpoints).
Also, write out the endpoint chains at the top of the loop when we
iterate the endpoints for the first time, rather than copying some of
the data to another set of variables and then writing them out later.
And don't write out endpoint chains that won't be used
Also, generate affinity rules only for readyEndpoints rather than
allEndpoints, so affinity gets broken correctly when an endpoint
becomes unready.
The external traffic policy terminating endpoints test was testing
LoadBalancer functionality against a NodePort service with no
nodePorts (or loadBalancer IPs). It managed to test what it wanted to
test, but it's kind of dubious (and we probably _shouldn't_ have been
generating the rules it was looking for since there was no way to
actually reach the XLB chains). So fix that.
Also make the terminating endpoints test use session affinity, to add
more testing for that. Also, remove the multiple copies of the same
identical Service that is used for all of the test cases in that test.
Also add a "Cluster traffic policy and no source ranges" test to
TestOverallIPTablesRulesWithMultipleServices since we weren't really
testing either of those.
Also add a test of --masquerade-all.
The test got broken to not actually use "no cluster CIDR" when
LocalDetector was implemented (and the old version of the unit test
didn't check enough to actually notice this).
The original tests here were very shy about looking at the iptables
output, and just relied on checks like "make sure there's a jump to
table X that also includes string Y somewhere in it" and stuff like
that. Whereas the newer tests were just like, "eh, here's a wall of
text, make sure the iptables output is exactly that". Although the
latter looks messier in the code, it's more precise, and it's easier
to update correctly when you change the rules. So just make all of the
tests do a check on the full iptables output.
(Note that I didn't double-check any of the output; I'm just assuming
that the output of the current iptables proxy code is actually
correct...)
Also, don't hardcode the expected number of rules in the metrics
tests, so that there's one less thing to adjust when rules change.
Also, use t.Run() in one place to get more precise errors on failure.
The test was sorting the iptables output so as to not depend on the
order that services get processed in, but this meant it wasn't
checking the relative ordering of rules (and in fact, the ordering of
the rules in the "expected" string was wrong, in a way that would
break things if the rules had actually been generated in that order).
Add a more complicated sorting function that sorts services
alphabetically while preserving the ordering of rules within each
service.
The --log-file parameter will be deprecated as of Kubernetes 1.23 and should be
avoided. The replacement for distroless images is the image with go-runner, a
tool that handles output redirection.
For kubemark to run in that image it must be built as static binary.
This makes it consistent with klog's text output and avoids polluting the
programs normal output with log messages. This may become relevant for command
line tools like "kubectl".
Instead of the individual error and return, it's better to aggregate all
the errors so that we can fix them all at once.
Take the chance to fix some comments, since kubeadm are not checking that
the certs are equal across controlplane.

* Bump the pod status and node status update timeouts to avoid flakes
* Add a small delay after dbus restart to ensure dbus has enough time to
restart to startup prior to sending shutdown signal
* Change check of pod being terminated by graceful shutdown. Previously,
the pod phase was checked to see if it was `Failed` and the pod reason
string matched. This logic needs to change after 1.22 graceful node
shutdown change introduced in PR #102344 which changed behavior to no
longer put the pods into a failed phase. Instead, the test now checks
that containers are not ready, and the pod status message and reason
are set appropriately.
