Tim Hockin e0fd83096c Rename type Port to ContainerPort 
Sadly I had to do this by hand - I just could not get gorename to fix up
users of it.

pkg/kubelet: recreate infra pod if the pod is changed
 2015-02-20 00:29:26 -08:00
Victor Marmol 8649628c6c Make POD container last OOM victim. 
Setting the oom_score_adj of the PID of the POD container to -100 which is less
than the default of 0. This ensures that this PID is the last OOM victim
chosen by the kernel.

Fixes #3067.

Don't delete the pod infrastructure container on health check failures.
 2015-02-13 15:18:27 -08:00
Victor Marmol 5d6ad845cc Use Docker name (not ID) to parse Kubernetes components. 
Since the parsing function doesn't return an error all the components
returned empty strings. This caused us to enforce the MaxContainerLimit
as a global limit instead of a per-container limit.

Fixes #4413.

Tim Hockin 6cb275829f Implement volumes as plugins. 
Break up the monolithic volumes code in kubelet into very small individual
modules with a well-defined interface.  Move them all into their own packages
and beef up testing along the way.

Daniel Smith 46f8a56dba Merge pull request #3376 from erictune/channel_api 
Kublet watches Pods.
 2015-01-15 14:48:12 -08:00
Eric Tune b759f67ee3 Kublet watches Pods. 
Added a kubelet config source for watching pods on apiserver.
The pods are converted to boundpods for merging with other
config sources.

The preferred way to create a kubelet is now to pass an apiserver
client but not an etcd client.  Changed cmd/integration to use
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.

saadali 110ab6f1bd Split up kubelet "source seen" logic 2015-01-12 21:48:55 -08:00
Tim Hockin 0d92da6b15 Remove logic to handle if UID is blank 
This should only have been triggered by tests, and those should now be fixed.
I tested by calling panic() if UID was blank in BuildDockerName() or if number
of fields was < 5 in ParseDockerName().  All errors were fixed.
 2015-01-12 14:27:34 -08:00
Tim Hockin 905514a12b Ensure Namespace and UID are set in kubelet 
Make all kubelet config sources ensure that UID and Namespace are defaulted, if
need be.

We can *almost* disable the "if blank" logic for UID, except for tests that
call APIs that do not run through SyncPods.  We really ought to be enforcing
invariants better.

Tim Hockin 523a80bec7 Apply more structure to pod data dirs 
This is makes it possible to read back "known" pods from disk without
getting other (non-pod) kubelet dirs in the mix.  Ditto for containers
within a pod.  This is just saner overall.  Pods now nest in a pods/
dir.  Likewise containers.

saadali e8d30f019d Modify "kubectl get events" to print FieldPath so BoundPod events for the same Pod but different containers can be differentiated 2014-12-29 21:32:49 -08:00
Tim Hockin 652479a3b1 Add kubelet DNS flags & api disable for DNS 
This adds --cluster_dns and --cluster_domain flags to kubelet.  If
non-empty, kubelet will set docker --dns and --dns-search flags based on
these.  It uses the cluster DNS and appends the hosts's DNS servers.
Likewise for DNS search domains.

This also adds API support to bypass cluster DNS entirely, needed to
bootstrap DNS.
