A lot of packages use StringSet, but they don't use anything else from
the util package. Moving StringSet into another package will shrink
their dependency trees significantly.
Both GetNode and the cache.ListWatch listfunc in the
kubelet package call List unnecessary.
GetNodeInfo is sufficient for GetNode and makes looping
through a list of nodes to check for a matching name
unnecessary.
resolves#13476
1. Add EvnetRecordQps and EventBurst parameter in kubelet.
2. If EvnetRecordQps and EventBurst was set, rate limit events in kubelet
with a independent ratelimiter as setted.
If stdin is noninteractive, the io.Copy from stdin to remoteStdin will
unblock when it finishes reading from stdin. In this case, make sure to
close remoteStdin so the server knows the client won't be sending any
more data. This ensures that the remote process terminates. For example:
echo foo | kubectl exec -i <pod> -- cat
Without this change, the `cat` process never terminates and `kubectl
exec` hangs.
Fix interactive exec sessions hanging after you type 'exit'.
Add e2e test to cover noninteractive stdin: `echo a | kubectl exec -i <pod>
cat`
Add e2e test to cover psuedo-interactive stdin: `kubectl exec -i <pod> bash`
Prep for sending multiple data frames over multiple streams in remote command
test, which is more likely to find flakes (requires bump of spdystream
once an issue with the frame worker queues not being fully drained when
a goaway frame is received).
PR #13293 added a safety check to not remove a pod directory if the child
volumes directory is not empty. This logic is faulty because kubelet may have
directory structures podUID/volumes/volumeKind/volumeName. E.g.,
`056db95d-50ee-11e5-a2e4-42010af0ba1d/volumes/kubernetes.io~empty-dir/default-token-al3r2`
This change fixes that by properly listing all volumes under a pod.
Before, kubelet performs global cleanup tasks every iteration. After the
PR #13003, kubelet performs the tasks on every sync internval (10 seconds).
This PR decouples the housekeeping period with the sync internval to ensure
that kubelet cleans up promptly, while not too often (no more than once every
minimum housekeeping period).
When the pod annotations are updated in the apiserver, update the pod.
Annotations may be used to convey attributes that are required to the
pod execution, such as networking parameters.
The health check is no longer needed since health checks are no longer
run by master but updated by the kubelet; so a host with the incorrect
host name will not be updated and show 'NotReady' status

Allow the user to specify the resolver configuration file that is used
to determine the default DNS parameters. This defaults to the system's
