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.

Dawn Chen 300c2c5f6f Fix an issue on GetContainerInfo. 
I believe the issue was first introduced when we append namespace to docker
container's name. This is a temporary fix for #160.

Clayton Coleman 4e56dafecc Introduce some default log verbosity control 
Move a lot of common error logging into better buckets:

glog.Errorf() - Always an error
glog.Warningf() - Something unexpected, but probably not an error
glog.V(0) - Generally useful for this to ALWAYS be visible
            to an operator
            * Programmer errors
            * Logging extra info about a panic
            * CLI argument handling
glog.V(1) - A reasonable default log level if you don't want
            verbosity
            * Information about config (listening on X, watching Y)
            * Errors that repeat frequently that relate to conditions
              that can be corrected (pod detected as unhealthy)
glog.V(2) - Useful steady state information about the service
            * Logging HTTP requests and their exit code
            * System state changing (killing pod)
            * Controller state change events (starting pods)
            * Scheduler log messages
glog.V(3) - Extended information about changes
            * More info about system state changes
glog.V(4) - Debug level verbosity (for now)
            * Logging in particularly thorny parts of code where
              you may want to come back later and check it

Tim Hockin 0f97a73c1b Rename a bunch of "Make" functions to "New" 
Also rename some to other names that make better reading.  There are still a
bunch of "make" functions but they do things like assemble a string from parts
or build an array of things.  It seemed that "make" there seemed fine.  "New"
is for "constructors".

derekwaynecarr fd8741edf2 Refactor kubelet to use http.ServeMux 2014-08-20 16:08:08 -05:00
Clayton Coleman 7767c2a2ac Switch the Kubelet to use kubelet/config 
Also transfer the Kubelet from using ContainerManifest.ID to source specific
identifiers with namespacing.  Move goroutine behavior out of kubelet/ and
into integration.go and cmd/kubelet/kubelet.go for better isolation.
 2014-07-21 21:27:26 -04:00
Dawn Chen 064237a5b8 Add support to query kubelet's logs and cadvisor's stats through

pods which do not exist and stop processing NotFound earlier in
the podinfo chain
