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.

Álex González fa39c2b032 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

kubelet: trigger pod workers independently
 2015-08-26 09:53:25 -07:00
Yu-Ju Hong b906e34576 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.

Eric Paris cde68d294b 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.
 2015-07-04 23:01:01 -04:00
Eric Paris 7a29af4d2c 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.

Add support for pluggable Docker exec handlers. The default handler is
now Docker's native exec API call. The previous default, nsenter, can be
selected by passing --docker-exec-handler=nsenter when starting the
kubelet.

Kubelet will stop accepting new pods if it detects low disk space on root fs or fs holding docker images.
Running pods are not affected. low-diskspace-threshold-mb is used to configure the low diskspace threshold.

Eric Paris 8e7d14196f Fix printing errors from failed binary runs 
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"
