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.

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 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.

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.

Clayton Coleman 6881db64a9 Allow configurable Kubelet net image for isolated networks 
Public access to the DockerHub is not guaranteed in all environments,
add a flag to the kubelet that allows it to use a different image (like
one on a private registry) as well as only pull the first time the
image is needed.

or build an array of things.  It seemed that "make" there seemed fine.  "New"
is for "constructors".

Victor Marmol b131da1cf5 Sync pods asynchronously in the Kubelet. 
This makes two main changes:
- Runs syncPod in a separate Go routine (and enforces only one of those
  runs at a time).
- Uses the pod list to determine if a container should be running or
  should be killed (used to use the output of syncPod).

Since Docker pulls are synchronized by the Docker daemon we still block
on that, but pods can now be removed and prepared for starting without
blocking on long pulls.
