...
Add `kube-reserved` and `system-reserved` flags for configuration
reserved resources for usage outside of kubernetes pods. Allocatable is
provided by the Kubelet according to the formula:
```
Allocatable = Capacity - KubeReserved - SystemReserved
```
Also provides a method for estimating a reasonable default for
`KubeReserved`, but the current implementation probably is low and needs
more tuning.

Mitigate node out of disk status oscillation by delaying it.
...
Implement a flag that defines the frequency at which a node's out of
disk condition can change its status. Use this flag to suspend out of
disk status changes in the time period specified by the flag, after
the status is changed once.
Set the flag to 0 in e2e tests so that we can predictably test out of
disk node condition.
Also, use util.Clock interface for all time related functionality in
the kubelet. Calling time functions in unversioned package or time
package such as unversioned.Now() or time.Now() makes it really hard
to test such code. It also makes the tests flaky and sometimes
unnecessarily slow due to time.Sleep() calls used to simulate the
time elapsed. So use util.Clock interface instead which can be faked
in the tests.

Add flocker volume plugin
...
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.
Full documentation can be found docs/user-guide/volumes.md and examples
can be found at the examples/ folder

Support pods with containers using host ipc
...
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.

kubelet: trigger pod workers independently
...
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.

Do not create subject alt dns names for kubelet self signed certs
...
PR #10643 Started adding the dns names for the kubernetes master to self
sign certs which were created. The kubelet uses this same code, and thus
the kubelet cert started saying it was valid for these name as well.
While hardless, the kubelet cert shouldn't claim to be these things. So
make the caller explicitly list both their ip and dns subject alt names.

Add Subject Alt Names to self signed apiserver certs
...
A cert from GCE shows:
- IP Address:23.236.49.122
- IP Address:10.0.0.1
- DNS:kubernetes,
- DNS:kubernetes.default
- DNS:kubernetes.default.svc
- DNS:kubernetes.default.svc.cluster.local
- DNS:e2e-test-zml-master
A similarly configured self signed cert shows:
- IP Address:23.236.49.122
- IP Address:10.0.0.1
- DNS:kubernetes
- DNS:kubernetes.default
- DNS:kubernetes.default.svc
So we are missing the fqdn kubernetes.default.svc.cluster.local. The
apiserver does not even know the fqdn! it's defined entirely by the
kubelet! We also do not have the cluster name certificate. This may be
--cluster-name= argument to the apiserver but will take a bit more
research.

I had the kublet die on startup and the only error was "0x401da0" Which
I assume is an address of the err.Error function. The other way to fix
this, I think, would be to use err.Error(), however that could cause
fmt.Fprintf() problems, debuging on the error message people used.
Now I get a nice clean error I can understand:
"cAdvisor.New() err = mountpoint for cpu not found"

Sync static pods from Kubelet to the API server
...
Currently, API server is not aware of the static pods (manifests from
sources other than the API server, e.g. file and http) at all. This is
inconvenient since users cannot check the static pods through kubectl.
It is also sub-optimal because scheduler is unaware of the resource
consumption by these static pods on the node.
This change syncs the information back to the API server by creating a
mirror pod via API server for each static pod.
- Kubelet creates containers for the static pod, as it would do
normally.
- If a mirror pod gets deleted, Kubelet will re-create one. The
containers are sync'd to the static pods, so they will not be
affected.
- If a static pod gets removed from the source (e.g. manifest file
removed from the directory), the orphaned mirror pod will be deleted.
Note that because events are associated with UID, and the mirror pod has
a different UID than the original static pod, the events will not be
shown for the mirror pod when running `kubectl describe pod
<mirror_pod>`.

This will make it easier to start running the real cAdvisor alongside

always be available. When we make a request, if cAdvisor is not
connected the request fails with a connection error. This failure is
handled today as well.

apiserver to talk to kubelets. And cmd/kubernetes.
Unit, integration, and e2e tests pass, except for a failure of the pd
e2e test which was unrelated.

0c5d9ed0d2
Implements a credentialprovider library for use by DockerPuller.
...
This change refactors the way Kubelet's DockerPuller handles the docker config credentials to utilize a new credentialprovider library.
The credentialprovider library is based on several of the files from the Kubelet's dockertools directory, but supports a new pluggable model for retrieving a .dockercfg-compatible JSON blob with credentials.
With this change, the Kubelet will lazily ask for the docker config from a set of DockerConfigProvider extensions each time it needs a credential.
This change provides common implementations of DockerConfigProvider for:
- "Default": load .dockercfg from disk
- "Caching": wraps another provider in a cache that expires after a pre-specified lifetime.
GCP-only:
- "google-dockercfg": reads a .dockercfg from a GCE instance's metadata
- "google-dockercfg-url": reads a .dockercfg from a URL specified in a GCE instance's metadata.
- "google-container-registry": reads an access token from GCE metadata into a password field.
