this change removes the deprecation warning function in favor of using
the `cloudprovider.DisableWarningForProvider`. it also fixes some of the
logic to ensure that non-external providers are properly detected and
warned about.
The information is received from the DRA driver plugin through a new gRPC
streaming interface. This is backwards compatible with old DRA driver kubelet
plugins, their gRPC server will return "not implemented" and that can be
handled by kubelet. Therefore no API break is needed.
However, DRA drivers need to be updated because the Go API changed. They can
return
status.New(codes.Unimplemented, "no node resource support").Err()
if they don't support the new ListAndWatchResources method and
structured parameters.
The controller in kubelet then synchronizes this information from the driver
with NodeResourceSlice objects, creating, updating and deleting them as needed.
27a68aee3a introduced context support for events. Creating an event
broadcaster with context makes tests more resilient against leaking goroutines
when that context gets canceled at the end of a test and enables per-test
output via ktesting.
To use this in kubelet, a more thorough code update is needed. For now,
context.TODO serves as a reminder that this is necessary.
This commit resolves an issue where certain KubeletConfig fields, specifically:
- FileCheckFrequency
- VolumeStatsAggPeriod
- EvictionPressureTransitionPeriod
- Authorization.Mode
- EvictionHard
were inadvertently overridden when not explicitly set in drop-in configs. To retain the
original values if they were absent in the drop-in configs, mergeKubeletConfigurations
uses a JSON patch merge strategy to selectively merge configurations. It prevents essential
configuration settings from being overridden, ensuring a more predictable behavior for users.

This removes deprecated sets.String and sets.Int
- replace sets.String with sets.Set[string]
- replace sets.Int with sets.Set[int]
- replace sets.NewString with sets.New[string]
- replace sets.NewInt with sets.New[int]
- replace sets.(OLD).List with sets.List(NEW)
As part of this change, the code responsible for managing the sandbox
image within the kubelet has been removed. Previously, the kubelet used
to prevent sandbox image from the garbage collection process. However,
with this update, the responsibility of managing the sandbox containers
has been shifted to the CRI implementation itself. By allowing sandbox
image pinning from CRI, we improve efficiency and simplify the kubelet's
interaction with the container runtime. As a result, the kubelet can now
rely on the container runtime's built-in mechanisms for sandbox container
lifecycle management.

This implements a drop-in configuration directory for the kubelet
by introducing a "--config-dir" flag. Users can provide individual
kubelet config snippets in separate files, formatted similarly to
kubelet.conf. The kubelet will process the files in alphanumeric order,
appending configurations if subfield(s) doesn't exist, overwriting them if
they do, and handling lists by overwriting instead of merging.

This patch modifies kubelet to get the cgroup driver setting from the
CRI runtime using the newly added RuntimeConfig rpc. The new code path
only takes place if the KubeletCgroupDriverFromCRI feature gate is
enabled. If the runtime returns a not-implemented error kubelet falls
back to using the cgroupDriver configuration option, with a log message
instructing the user to upgrade to w newer container runtime. Other rpc
errors cause kubelet to exit as is the case if the runtime returns an
unknown cgroup driver.
This patch refactors the kubelet startup code to initialize the runtime
service earlier in the startup sequence. We want this to be able to
query the cgroup driver setting from the CRI befure initializing the
cgroup manager.
