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.

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 af0e2fd551 Merge pull request #3403 from thockin/klet-dirs-structure

saadali e1917cf900 Fix "Kubelet doesn't kill old pods when BoundPods is empty" issue 2015-01-12 12:39:47 -08:00
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 eb831919d9 Improve kubelet logging around container being killed due to hash change 2015-01-05 16:20:40 -08:00
Angus Lees 6f14e2e210 Avoid race between image pull and garbage collect 
Hold the pullLock while pulling regular container images, not just the
network container.

Also: previously, the locks were grabbed at too-low a layer in the
callstack, leaving a (narrow) window where images could be pulled and
then garbage collected before being used.

This change takes the existing pullLock a layer higher in the call stack
so the critical regions encompass the entire find+delete and pull+use
operation in both cases.

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.

Clayton Coleman 892942af8f Read BoundPods from etcd instead of ContainerManifestList 
There are three values that uniquely identify a pod on a host -
the configuration source (etcd, file, http), the pod name, and the
pod namespace. This change ensures that configuration properly
makes those names unique by changing podFullName to contain both
name (currently ID in v1beta1, Name in v1beta3) and namespace.

The Kubelet does not properly handle information requests for
pods not in the default namespace at this time.
