it turns out that the e2e test was no using the timeout used to
hold the CLOSE_WAIT status, hence the test was flake depending
on how fast it checked the conntrack table.
This PR replaces the dependency on ssh using a pod to check the conntrack
entries on the host in a loop, to make the test more robust
and reduce the flakiness due to race conditions and/or ssh issues.
It also fixes a bug trying to grep the conntrack entry, where
the error was swallowed if a conntrack entry wasn't found..
Some tests are setting HostNetwork=true, even if it is not required
for them to pass.
This patch will set the HostNetwork to false for those tests, allowing
them to be run on Windows nodes as well.
Ensures that requests that require large packets work properly, and that
they are not dropped.
Adds AgnhostPrivate to test/utils/image/manifest. Some tests are trying to pull
the agnhost image from the private registry, meaning that we would need to
always build and push the agnhost image to both e2e and private registry
whenever we bump its version. Decoupling them would mean that we only need
to push the image to the e2e registry.
Since EndpointSlices and Endpoints are expected to be enabled by default
for some time, it's important to have tests covering the functionality
of both controllers. With some consumers relying on Endpoints and others
relying on EndpointSlices, it's important to ensure both resources are
generated in a timely manner with consistent attributes.
The following functions are called at some specific places only,
so this moves these functions to the places and makes them local.
- WaitForPersistentVolumeClaimDeleted: Moved to e2e storage
- PrintSummaries: Moved to e2e framework.go
- GetHostExternalAddress: Moved to e2e node
- WaitForMasters: Moved to e2e cloud gcp
- WaitForApiserverUp: Moved to e2e network
- WaitForKubeletUp: Moved to e2e storage vsphere
This PR moves functions from test/e2e/framework.util.go for making e2e
core framework small and simple:
- RestartKubeProxy: Moved to e2e network package
- CheckConnectivityToHost: Moved to e2e network package
- RemoveAvoidPodsOffNode: Move to e2e scheduling package
- AddOrUpdateAvoidPodOnNode: Move to e2e scheduling package
- UpdateDaemonSetWithRetries: Move to e2e apps package
- CheckForControllerManagerHealthy: Moved to e2e storage package
- ParseKVLines: Removed because of e9345ae5f0
- AddOrUpdateLabelOnNodeAndReturnOldValue: Removed because of ff7b07c43c
- SimpleGET: Moved to ingress sub package of e2e framework
- PollURL: Moved to ingress sub package of e2e framework
- ProxyMode: Moved to service e2e test package
- ListNamespaceEvents: Moved to e2e_node test package
- NewE2ETestNodePreparer: Removed since 59533f0cd1
Many functions of networking_utils are used at e2e network only.
To make e2e core framework small as possible for reducing invalid
dependencies to e2elog subpackage, this moves these functions to
e2e network tests.
LaunchHostExecPod() is called only from e2e network.
So it is not necessary to keep the function as a part of e2e framework.
This moves it to the place which calls the function.
Many TestJig methods made the caller pass a serviceName argument, even
though the jig already has a name, and every caller was passing the
same name to each function as they had passed to NewTestJig().
Likewise, many methods made the caller pass a namespace argument, but
only a single test used more than one namespace, and it can easily be
rewritten to use two test jigs as well.
A number of tests were using hardcoded image paths instead of
going through the imageutils package. The reason for centralizing
the logic there is to keep an eye on what images we use and where
they come from.
Remove the "OrDie" from the name (since it doesn't "or die") and add
an extra check that there is at least 1 node available, since many
callers already did that themselves, and many others should have.
