Dan Mace 3d7f5cc642 Backport annotations to PodTemplateSpec 
Backport annotation support to v1beta1 and v1beta2 PodTemplateSpec. This
allows ReplicationController users to specify annotations for Pods in
addition to labels.

Clayton Coleman 5603714df8 Use name generation on pods via replication controllers 
The generated name is '<controllerName>-%s', unless controllerName-
would be long enough to cause a validation error.

Clayton Coleman 19987612bf Replace code that eats errors with a more consistent reporting 
In order to allow certain programmer error / unexpected error states
to be captured, replace sections that log and eat errors with a method
that can be centrally replaced.  This captures two common error sources,
replication errors, and apiserver code that returns invalid errors.

Use %v for errors, tidy some messages, make error messages start lowe-case
(as per go guidelines).  Just accumulated nits.

Clayton Coleman 82bcdd3b3b Make ResourceVersion a string internally instead of uint64 
Allows us to define different watch versioning regimes in the future
as well as to encode information with the resource version.

This changes /watch/resources?resourceVersion=3 to start the watch at
4 instead of 3, which means clients can read a resource version and
then send it back to the server. Clients should no longer do math on
resource versions.

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".

Daniel Smith 5cdce0e35a Prepare for external scheduler 
1. Change names of Pod statuses (Waiting, Running, Terminated).
2. Store assigned host in etcd.
3. Change pod key to /registry/pods/<podid>. Container location remains
   the same (/registry/hosts/<machine>/kublet).

Daniel Smith b430cebe72 Remove etcd dependency from controller manager. 2014-08-04 14:29:49 -07:00
Clayton Coleman 4448be2d95 Expose an Encoding/Versioning interface for use with etcd 
etcd_tools.go is not dependent on the specific implementation
(which is provided by pkg/api).  All EtcdHelpers are created
with an encoding object which handles Encode/Decode/DecodeInto.
Additional tests added to verify simple atomic flows.

Begins to break up api singleton pattern.

Daniel Smith 928092e79e Etcd watcher verification 
To make sure the etcd watcher works, I changed the replication
controller to use watch.Interface. I made apiserver support watches on
controllers, so replicationController can be run only off of the
apiserver. I made sure all the etcd watch testing that used to be in
replicationController is now tested on the new etcd watcher in
pkg/tools/.
