In e2e test framework, ProxyRequest() is called in kubelet e2e test
framework only. In addition, the function works for kubelet as tests
which call the function do. So this moves the function into kubelet
e2e test framework to make the dependency simple.
Using a "normal" CSI driver for an inline ephemeral volume may have
unexpected and potentially harmful effects when the driver gets a
NodePublishVolume call that it isn't expecting. To prevent that mistake,
driver deployments for a driver that supports such volumes must:
- deploy a CSIDriver object for the driver
- set CSIDriver.Spec.VolumeLifecycleModes such that it contains "ephemeral"
The default for that field is "persistent", so existing deployments
continue to work and are automatically protected against incorrect
usage.
For the E2E tests we need a way to specify the driver mode. The
existing cluster-driver-registrar doesn't support that and also was
deprecated, so we stop using it altogether and instead deploy and
patch a CSIDriver object.
A previous commit replaced the usage of hostname -i with getent hosts
in DNS probe commands (for testing IPv6), which breaks the Windows tests
(getent hosts is a Linux-specific command that looks into the /etc/hosts
file, which, on Windows, is not managed by Kubelet).
This commit addresses this issue by executing getent hosts on IPv6 clusters
and hostname -i on IPv4 clusters (Windows does not support IPv6 at this
moment).
The core e2e framework contains BusyBoxImage. The sub e2e "pod"
framework also contains it but not used at all.
So this removes this unused BusyBoxImage for code cleanup.
WaitForEndpoint() of the endpoints e2e framework was used in
test/e2e/network/proxy.go only. In addition, the endpoints e2e
framework imported the core of e2e framework only for the function.
So this moves the function into test/e2e/network/proxy.go then we
can remove dependency of core framework from the sub e2e framework.
RunDeployment() of the deployment e2e framework was used in
autoscaling_utils only. In addition, the deployment e2e framework
imported the core of e2e framework only for the function.
So this moves the function into autoscaling_utils then we can remove
dependency of core framework from the deployment e2e framework.
Originally, printOnce() was implemented for printing debugging message
once for checking actual value is the same as expected value.
However even if an error doesn't happen in ExpectEqual(), printOnce()
is called internally. Then the second ExpectEqual() doesn't output
the debugging message if an error happens. This makes debugging
difficult, let's just remove it for debugging.
A number of tests rely on SSH behavior but are not marked with
SkipUnlessSSHKeysPresent(). This means that the tests will run and
hang. This can be confusing for users because they may not know why
the tests failed. Instead, we should be reporting on the known issue
and skipping the test (hence why the helper Skip... function exists).
The conformance test "validates resource limits of pods that are
allowed to run" is failed if master node doesn't have taints.
The reason is that nodeList which should consist of schedulable
nodes is gotten with GetMasterAndWorkerNodes() and master nodes
were excluded from nodeList.
This makes nodeList be gotten with GetReadySchedulableNodesOrDie()
and nodeList can consist of schedulable nodes.
