This commit addresses issue #1571, which requests that all internal
Kubernetes links are swapped to relative ones to better facilitate
browsing of documentation on local forks, not to mention make the
documentation have less needless boilerplate.
* Separate metadata from objects
* Treat lists differently from resources
* Add UID and Annotations on Metadata
* Introduce BoundPod(s) as distinct from Pod to represent pods
scheduled onto a host
* Use "spec" instead of "state" and "status" instead of "currentState"
* Identify current status of objects consistently
* Use "condition" as the string label for substatus
* All string constants should be PublicGoCapitalized
* Rename Minion -> Node
* Rename ServerOp -> Operation
* Remove ContainerManifest
* Add api-conventions.md document
* Replace PodTemplateSpec in ReplCtrl with ObjectReference
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
I skip using `go get` as it downloads all of the dependencies. But since we are vendoring using godep without rewriting imports, this means we download a bunch of stuff we don't use. Instead, just clone the repo directly.
Fixes#1360.
v2: Resolve issues from comments, fix bugs in update-demo example, rename files for clarity, add turn-down steps.
v3: Add more set commands, clean up rest of env var checks.
