Jan Chaloupka 663fbce3a0 Kubelet: node allocatable resources: negative quantities should not be allowed 
When setting kube/system-resources for a node, negative quantities can result in
node's allocatable being higher then node's capacity.
Let's check the quantity and return error if it is negative.

Tim St. Clair e2ffd007f7 Implement node Allocatable 
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.

Madhusudan.C.S 059c2aa799 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.

Matt McCoy 5a2f992d75 Fixing kubelet cmd documentation for register-node argument 2015-08-27 21:04:08 -04:00
Pedro Roque Marques 99b1da848d Add kubelet '--resolv-conf' flag. 
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.

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.

Jonathan Wills 80e799fc0c Allow configuring the rkt binary in a kubelet with a flag. 
This is necessary because coreos comes with rkt installed, and if we want to use a different version
we need some way to avoid the default one.

Eric Paris fe6b633e2a Convert for util.IP to just use a net.IP 
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!

Clayton Coleman bb79365e2a Split kubelet server initialization into two parts 
First is initializing a KubeletConfig that starts no background
processes. Second is running the config. Provide a legacy path
that won't impact older callers while making it easier to customize
the interfaces passed to the Kubelet.

Used by OpenShift to inject some custom interfaces to the Kubelet
for config management.

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.

Robert Bailey bc8af553a3 Configure the kubelet to bind a simple healthz server to a localhost 
port for monitoring by monit. This is in preparation for the standard
kubelet port to switch to SSL only (and eventually to only accepting
connections on the SSL port that present a proper client SSL cert).

Also standardize the formatting of the monit config files a bit.
