Before deleting an object based on absent owners, GC verifies absence of those owners with a live lookup.
The coordinates used to perform that live lookup are the ones specified in the ownerReference of the child.
In order to performantly delete multiple children from the same parent (e.g. 1000 pods from a replicaset),
a 404 response to a lookup is cached in absentOwnerCache.
Previously, the cache was a simple uid set. However, since children can disagree on the coordinates
that should be used to look up a given uid, the cache should record the exact coordinates verified absent.
This is a [apiVersion, kind, namespace, name, uid] tuple.
The e2e test, included as part of Conformance,
"validates that there is no conflict between
pods with same hostPort but different hostIP and protocol"
was only testing that the pods were scheduled without conflict
but was never testing the functionality.
The test should check that pods with containers forwarding the same
hostPort can be scheduled without conflict, and that those exposed
HostPort are forwarding the ports to the corresponding pods.
the predicate tests were using loopback addresses for the the
hostPort test, however, those have different semantics depending
on the IP family, i.e. you can not bind to ::1 and ::2 simultanously,
in addition, IP forwarding from localhost to localhost in IPv6 is
not working since it doesn't have the kernel route_localnet hack.
- as soon as a request is received by the apiserver, determine the
timeout of the request and set a new request context with the deadline.
- the timeout filter that times out non-long-running requests should
use the request context as opposed to a fixed 60s wait today.
- admission and storage layer uses the same request context with the
deadline specified.
The test code generation for create subresource was missing the resource
name parameter in the template which caused a compile error for the
sample projects using the scale subresource. That only occurs with
non-namespaced resource kind.
Also re-ran the code generation after applying the fix.
* Mixed protocol support for Services with type=LoadBalancer
KEP: https://github.com/kubernetes/enhancements/blob/master/keps/sig-network/20200103-mixed-protocol-lb.md
Add new feature gate to control the support of mixed protocols in Services with type=LoadBalancer
Add new fields to the ServiceStatus
Add Ports to the LoadBalancerIngress, so cloud provider implementations can report the status of the requested load balanc
er ports
Add ServiceCondition to the ServiceStatus so Service controllers can indicate the conditions of the Service
* regenerate conflicting stuff
Relaxes matching of pod_memory_working_set_bytes metric so that we won't
error due to presence of other pods.
