Prepares for the meta object to front multiple underlying types
when TypeMeta and ObjectMeta is split in internal and v1beta3, but
combined in v1beta1 and v1beta2
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.
* Allows consumers to provide their own transports for common cases.
* Supports KUBE_API_VERSION on test cases for controlling which
api version they test against
* Provides a common flag registration method for CLIs that need
to connect to an API server (to avoid duplicating flags)
* Ensures errors are properly returned by the server
* Add a Context field to client.Config
* Defaults to v1beta1
* apiserver takes -storage_version which controls etcd storage version
and the version of the client used to connect to other apiservers
* Changed signature of client.New to add version parameter
* All controller code and component code prefers the oldest (most common)
server version
* Make Codec separate from Scheme
* Move EncodeOrDie off Scheme to take a Codec
* Make Copy work without a Codec
* Create a "latest" package that imports all versions and
sets global defaults for "most recent encoding"
* v1beta1 is the current "latest", v1beta2 exists
* Kill DefaultCodec, replace it with "latest.Codec"
* This updates the client and etcd to store the latest known version
* EmbeddedObject is per schema and per package now
* Move runtime.DefaultScheme to api.Scheme
* Split out WatchEvent since it's not an API object today, treat it
like a special object in api
* Kill DefaultResourceVersioner, instead place it on "latest" (as the
package that understands all packages)
* Move objDiff to runtime.ObjectDiff
In particular, add support for -server_version=raw and use matching
format for the output of -version and -server_version.
The "normal" format is essentially defined by (version.Info) String()
method, so future updates to that method will be reflected on both.
Full version information is still available by using the "raw" flag.
Tested:
- Used cluster/kubecfg.sh to query local build and the server.
$ cluster/kubecfg.sh -version
Kubernetes version 0.2+, build 9316edfc0d2b28923fbb6eafa38458350859f926
$ cluster/kubecfg.sh -server_version
Server: Kubernetes version 0.2, build a0abb38157
$ cluster/kubecfg.sh -version=raw

Use images and some better formatting. Also add scripts to help prevent typos.
This based on an improved version done by Julia Ferraioli. She came up with the cool images.
