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.

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.

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.
