Victor Marmol 51122998e3 Garbage collect unidentified Kubernetes containers. 
These containers may be caused by a change in the Kubernetes naming
convention. The old containers are killed, the new ones started, but the
old ones are never GC'd. This change makes Kubelet GC all Kubernetes
containers, old and new.

Fixes #5372.

 2015-03-09 11:36:03 -07:00
Victor Marmol ab3c9de34b Refactoring cAdvisor interface into a package. 
This will make it easier to start running the real cAdvisor alongside
Kubelet. This change is primarily no-op refactoring. The main behavioral
change is that we always create a cAdvisor interface and expect it to
always be available. When we make a request, if cAdvisor is not
connected the request fails with a connection error. This failure is
handled today as well.

Victor Marmol ca84aae454 Kubelet: wait up to 5m for Docker to come up. 
The Kubelet assumes Docker is running during its execution and on
machine boot it is a race between Docker coming up and Kubelet calling
Docker. This PR waits for Docker to be up before the Kubelet begins
doing useful work. On timeout, Kubelet exits and expects to be
restarted.

Yu-Ju Hong fe70be9261 kubelet: revamp the pod/container naming scheme 
There are two main goals for this change.

 1. Fix the naming scheme in kubelet so that it accepts DNS subdomain
    name/namespaces correctly (#4920). The design is discussed in #3453.

 2. Prepare for syncing the static pods back to the apiserver(#4090). This
    includes

  - Eliminate the source component in the internal full pod name (#4922). Pods
    no longer need sources as they will all be sync'd via apiserver.

  - Changing the naming scheme for the static (file-, http-, and etcd-based)
    pods such that they are distinguishable when syncing back to the apiserver.

The changes includes:
  *	name = <pod.Name>-<hostname>
  * namespace = <cluster_namespace> (i.e. "default" for now).
  * container_name = k8s_<contianer_name>.<hash_of_container>_<pod_name>_<namespace>_<uid>_<random>

Note that this is not backward-compatible, meaning the kubelet won't recognize
existing running containers using the old naming scheme.

Yu-Ju Hong 32fd331e73 Revert "Split up kubelet "source seen" logic" 
We want to sync pods from file/http/etcd sources to the apiserver, hence
differentiating sources is no longer desired.

Yu-Ju Hong 3ccdb8db98 kubelet: reject pods on host port conflict 
When a host port conflict is detected, kubelet should set the pod status to
fail. The failed status will then be polled by other components at a later time,
which allows replication controller to create a new pod if necessary.

To achieve this, this change stores the pod status information in a status map
upon the detecton of port conflict. GetPodStatus() consults this status map
before attempting to query docker. The entries in the status map will be removed
when the pod is no longer associated with the node.

kubelet: record an event with a clear reason on host port conflict
 2015-02-27 16:04:04 -08:00
Yu-Ju Hong 241df2d3be kubelet: record an event with a clear reason on host port conflict 
Currently, kubelet silently ignores pods that caused host port conflict. This
commit surfaces the error by recording an event.

It also makes sure that kubelet iterates through the pods in the order of the
creation timestamp, which ensures that pods created later are ignored on
conflict.

Victor Marmol 5d6ad845cc Use Docker name (not ID) to parse Kubernetes components.

Yu-Ju Hong 4a72addaeb Factor out API defaulting from validation logic 
Currently, the validation logic validates fields in an object and supply default
values wherever applies. This change factors out defaulting to a set of
defaulting callback functions for decoding (see #1502 for more discussion).

 * This change is based on pull request 2587.

 * Most defaulting has been migrated to defaults.go where the defaulting
   functions are added.

 * validation_test.go and converter_test.go have been adapted to not testing the
   default values.

 * Fixed all tests with that create invalid objects with the absence of
   defaulting logic.

Matt Moore 2d396797a9 Fix for issue 3797. 
Docker's logic for resolving credentials from .dockercfg accepts two kinds of matches:
1. an exact match between the dockercfg entry and the image prefix
2. a hostname match between the dockercfg entry and the image prefix

This change implements the latter, which permits the docker client to take .dockercfg entries of the form:
   https://quay.io/v1/
and use them for images of the form:
   quay.io/foo/bar
even though they are not a prefix-match.

float this for review first.
