Clean up the code paths that lead to objects being transformed and output with negotiation.
Remove some duplicate code that was not consistent. Now, watch will respond correctly to
Table and PartialObjectMetadata requests. Add unit and integration tests.
When transforming responses to Tables, only the first watch event for a given type will
include the columns. Columns will not change unless the watch is restarted.
Add a volume attachment printer and tighten up table validation error cases.
Disable protobuf from table conversion because Tables don't have protobuf because they
use `interface{}`
Windows containers do not include a route to the GCE metadata server by
default. This check is causing the "DNS should provide DNS for the
cluster" test to fail for clusters with Windows nodes
(https://testgrid.k8s.io/sig-windows#gce-windows-master&width=20).
Tested that this works by running "DNS should provide DNS for the
cluster" against an e2e cluster with Windows nodes brought up on GCE.
Current IPv6 e2e test for external connectivity is using a
domain address (google.com) as target.
However, the same IPv4 test uses the well known Google DNS address
8.8.8.8.
We should be coherent in the testing, this patch changes the target to use
the Google IPv6 DNS address 2001:4860:4860::8888.
It looks like node does become unschedulable for the pod
but condition does not get added to the pod in time.
Also ginkgo could retry the test and hence it helps to use
unique node label for scheduling.
When using an already installed driver, the snapshot name is the
original driver name. Renaming was incorrectly copied from the in-tree
CSI hostpath driver.
It is useful to apply the storage testsuite also to "external" (=
out-of-tree) storage drivers. One way of doing that is setting up a
custom E2E test suite, but that's still quite a bit of work.
An easier alternative is to parameterize the Kubernetes e2e.test
binary at runtime so that it instantiates the testsuite for one or
more drivers. Some parameters have to be provided before starting the
test because they define configuration and capabilities of the driver
and its storage backend that cannot be discovered at runtime. This is
done by populating the DriverDefinition with the content of the file
that the new -storage.testdriver parameters points to.
The universal .yaml and .json decoder from Kubernetes is used. It's
flexible, but has some downsides:
- currently ignores unknown fields (see https://github.com/kubernetes/kubernetes/pull/71589)
- poor error messages when fields have the wrong type
Storage drivers have to be installed in the test cluster before
starting e2e.test. Only tests involving dynamically provisioned
volumes are currently supported.
