This allows to choose the correct architecture in the image manifest,
which defaulted to the host system before applying this patch.

Add the UIDs of Pods for which we are removing finalizers to an in-memory cache.
The controller removes UIDs from the cache as Pod updates or deletes come in.
This avoids double counting finished Pods when Pod updates arrive after Job status updates.

This commit fixes the LocalStorageCapacityIsolationEviction test by
acknowledging that in its default configuration kubelet will no-longer
evict memory-backed volume pods as they cannot use more than their
assigned limit with SizeMemoryBackedVolumes enabled.
To account for the old behaviour, we also add a test that explicitly
disables the feature to test the behaviour of memory backed local
volumes in those scenarios. That test can be removed when/if the feature
gate is removed.
Currently the storage eviction tests fail for a few reasons:
- They re-enter storage exhaustion after pulling the images during
cleanup (increasing test storage reqs, and adding verification for
future diagnosis)
- They were timing out, as in practice it seems that eviction takes just
over 10 minutes on an n1-standard in many cases. I'm raising these to
15 to provide some padding.
This should ideally bring these tests to passing on CI, as they've now
passed locally for me several times with the remote GCE env.
Follow up work involves diagnosing why these take so long, and
restructuring them to be less finicky.
Upstream klog continues to support all of its flags, but in Kubernetes only
some will be supported going format (-v, -vmodule). With this change,
the kubelet flags now look like this:
$ go run ./cmd/kubelet --help | grep -e --log-dir -e '--v ' -e --vmodule -e --logging-format
--log-dir string If non-empty, write log files in this directory (DEPRECATED: will be removed in a future release, see https://github.com/kubernetes/enhancements/tree/master/keps/sig-instrumentation/2845-deprecate-klog-specific-flags-in-k8s-components)
--logging-format string Sets the log format. Permitted formats: "json", "text".
Non-default formats don't honor these flags: --add_dir_header, --alsologtostderr, --log_backtrace_at, --log_dir, --log_file, --log_file_max_size, --logtostderr, --one_output, --skip_headers, --skip_log_headers, --stderrthreshold, --vmodule, --log-flush-frequency, --add_dir_header, --alsologtostderr, --log_backtrace_at, --log_dir, --log_file, --log_file_max_size, --logtostderr, --one_output, --skip_headers, --skip_log_headers, --stderrthreshold, --vmodule.
-v, --v Level number for the log level verbosity
--vmodule moduleSpec comma-separated list of pattern=N settings for file-filtered logging
Previously, the situation was ignored, which might have had the effect that Pod
scheduling continued (?) even though the Pod+PVC weren't known to be in an
acceptable state.
When adding the ephemeral volume feature, the special case for
PersistentVolumeClaim volume sources in kubelet's host path and node
limits checks was overlooked. An ephemeral volume source is another
way of referencing a claim and has to be treated the same way.
