On HA API server hiccups we saw a prow job with error:
fail [k8s.io/kubernetes@v1.19.0/test/e2e/e2e.go:284]: Sep 30 17:06:08.313: Error waiting for all pods to be running and ready: 0 / 0 pods in namespace "kube-system" are NOT in RUNNING and READY state in 10m0s
POD NODE PHASE GRACE CONDITIONS
The failure should include the last error from API server, if it's
available:

This fixes a problem when using the framework helper
e2epod.CreateExecPodOrFail() more than once in the same test.
The problem is that this function was creating pods with both the
pod.Name and pod.GenerateName set.
The second pod failed to be created with a 500 with Reason ServerTimeout
indicating a unique name could not be found in the time allotted,

For testing certain features, the BusyBox image does not provide all the
tools that are needed. Notably 'dd' from BusyBox does not support
direct-io that is required for skipping caches while doing writes and
reads on a Block-mode PVC attached to different nodes.
This reverts commit 61490bba46, reversing
changes made to 9ecab1b4b2.
Some methods from the networking e2e tools are dialing from a
containter to another container, and failing the test if there was no
connectivity. This PR modified the methods to return an error instead of
failing the test.
However, these methods were used by other tests in the framework, and
they are not checking if the method returns an error, expecting that
the method fail the test. With this change, any connectivity problem
will go unnoticed on the tests that are not asserting the error, so we
need to revert to previous state.
Creates a few agnhost related functions that creates agnhost
pods / containers for general purposes.
The following commits will refactor tests to use those functions.
Since 1.19 endpoint slices is enabled by default, so all the e2e
tests should consider them.
The e2e networking tests for services use the jig object for
all the tests, but was not taking into account endpoint slices.
This considers endpoints slices for the method waitForAvailableEndpoint()

As a part of cleaning up inactive members (who haven't been active since
beginning of 2019) from OWNERS files, this commit moves abrarshivani to
emeritus_approvers section.
This PR fixes a few things for e2e storage suite to run on Windows
cluster.
1. increaes timeout due to longer pod startup time for windows
2. Only set SELinuxOptions or fsGroup if os is not windows
3. Add VolumeSnapshot delete policy for windows3. Add VolumeSnapshot
delete policy for windows3. Add VolumeSnapshot delete policy for windows
Some of the tests are negative test cases which are supposed to ensure that those
invalid usecases are handled properly.
However, some of the tests are false positives, they can pass due to various reasons.
One such example is: "should fail substituting values in a volume subpath with absolute path".
This test can pass if:
- the Pod cannot start due to various reasons (e.g.: the container image cannot be pulled or does
not exist).
- the Pod ran to completion, even though the container was not supposed to start in the first place.
MasterUpgrade() is called only from cloud/gcp/cluster_upgrade.go.
And the function depends on GCP, so it is nice to move this function
from e2e framework.
This removes DeprecatedGetMasterAndWorkerNodes() usage from vsphere e2e
test as deprecated function cleanup.
Then all callers of DeprecatedMightBeMasterNode() have been removed.
So this removes DeprecatedMightBeMasterNode() itself also.
This is useful in case that the pod owns some resources, because then
waiting for the pod ensures that those resources also were removed.
This should not matter at the moment because pods typically are not
owners of any other object, but that will change with the introduction
of generic ephemeral inline
volumes (https://github.com/kubernetes/enhancements/tree/master/keps/sig-storage/1698-generic-ephemeral-volumes).
DeprecatedMightBeMasterNode() has been marked as deprecated and we need to
find alternative way for callers of the function.
In NewResourceUsageGatherer(), the function was called for distinguishing
the specified pods are running on master nodes, and the gatherer gathers
those pods' resource usage.
This adds nodeHasControlPlanePods() to gistinguish the specified pods
are running on nodes which are operating control plane pods (kube-scheduler
and kube-controller-manager) and replace callers of DeprecatedMightBeMasterNode()
with this new function as better way.
This drops testfiles.ReadOrDie and updated testfiles.Exists to return an
error, forcing the caller to decide whether to call framework.Fail or do
something else.
It makes for a slightly less friendly API, but also means the package is
decoupled from framework again, as per the comments at the top of the
file
As its name, DeprecatedMightBeMasterNode is deprecated.
In e2e metrics, the function was used for knowing master node name to
get metrics from kube-scheduler and kube-controller-manager pods.
This make e2e metrics get these metrics directly by getting those pod
names without calling DeprecatedMightBeMasterNode().
WaitForStableCluster() checks all pods run on worker nodes, and the
function used to refer master nodes to skip checking controller plane
pods.
GetMasterAndWorkerNodes() was used for getting master nodes, but the
implementation is not good because it usesDeprecatedMightBeMasterNode().
This makes WaitForStableCluster() refer worker nodes directly to avoid
using GetMasterAndWorkerNodes().
e2e/framework is a place to keep common functions for e2e tests, and
it is not a place to keep e2e tests themself. recreate_node.go is e2e
test for node.
This moves recreate_node.go to e2e/node.
