- pre-create node api objects from the scheduler when offers arrive
- decline offers until nodes a registered
- turn slave attributes as k8s.mesosphere.io/attribute-* labels
- update labels from executor Register/Reregister
- watch nodes in scheduler to make non-Mesos labels available for NodeSelector matching
- add unit tests for label predicate
- add e2e test to check that slave attributes really end up as node labels
- instantiate framework.Controller for pods in the executor using framework.NewInformer,
in order to watch pod updates for pods on that host
- forwards updates like graceful termination to the kubelet.
This might also be the preparation for other updates which are supported by the
kubelet.
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.
Allow the user to specify the resolver configuration file that is used
to determine the default DNS parameters. This defaults to the system's
/etc/resolv.conf.
Currently, whenever there is any update, kubelet would force all pod workers to
sync again, causing resource contention and hence performance degradation.
This commit flips kubelet to use incremental updates (as opposed to snapshots).
This allows us to know what pods have changed and send updates to those pod
workers only. The `SyncPods` function has been replaced with individual
handlers, each handling an operation (ADD, REMOVE, UPDATE). Pod workers are
still triggered periodically, and kubelet performs periodic cleanup as well.
This commit also spawns a new goroutine solely responsible for killing pods.
This is necessary because pod killing could hold up the sync loop for
indefinitely long amount of time now user can define the graceful termination
period in the container spec.
In contrast to the docker and system containers (= cgroup path) this has no
undesired consequence, only that the kubelet itself will be in its own cgroup
below the executor cgroup.
pflag can handle IP addresses so use the pflag code instead of doing it
ourselves. This means our code just uses net.IP and we don't have all of
the useless casting back and forth!
