Set resyncInterval to one minute now that we rely on the generic pleg to trigger
pod syncs on container events. When there is an error during syncing, pod
workers need to wake up sooner to retry. Set the sync error backoff period to
10 second in this case.
Default to hardcodes for components that had them, and 5.0 qps, 10 burst
for those that relied on client defaults
Unclear if maybe it'd be better to just assume these are set as part of
the incoming kubeconfig. For now just exposing them as flags since it's
easier for me to manually tweak.
Flocker [1] is an open-source container data volume manager for
Dockerized applications.
This PR adds a volume plugin for Flocker.
The plugin interfaces the Flocker Control Service REST API [2] to
attachment attach the volume to the pod.
Each kubelet host should run Flocker agents (Container Agent and Dataset
Agent).
The kubelet will also require environment variables that contain the
host and port of the Flocker Control Service. (see Flocker architecture
[3] for more).
- `FLOCKER_CONTROL_SERVICE_HOST`
- `FLOCKER_CONTROL_SERVICE_PORT`
The contribution introduces a new 'flocker' volume type to the API with
fields:
- `datasetName`: which indicates the name of the dataset in Flocker
added to metadata;
- `size`: a human-readable number that indicates the maximum size of the
requested dataset.

Add an experimental network plugin implementation named "cni" that
uses the Container Networking Interface (CNI) specification for
configuring networking for pods.

Add a HostIPC field to the Pod Spec to create containers sharing
the same ipc of the host.
This feature must be explicitly enabled in apiserver using the
option host-ipc-sources.
