* 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
It turns out that that's simply the most useful information about the version
that was built.
For a git tree, it includes information about the closest release, number of
commits since the release, enough of the SHA1 to find the exact commit and
whether the tree was clean or dirty at build time.
For a build from tarball, it will include information of which release was built
and, when using a tarball from a not released commit (e.g. downloading
"master.tar.gz" from GitHub, not recommended!) it will include the -dev prefix
to indicate that was not an official release. (That's as good as we can get with
it.)
If additional information is required, it can be found with -version=raw.
Tested:
- Built from the git tree:
$ _output/go/bin/kubecfg -version
Kubernetes v0.2-29-gd916051e9db865
$ _output/go/bin/kubecfg -version=raw
version.Info{Major:"0", Minor:"2+", GitVersion:"v0.2-29-gd916051e9db865", GitCommit:"d916051e9db8650899acb9415a4e285e3e3a1f87", GitTreeState:"clean"}
- Built it from a dirty git tree:
$ { echo 'package version'; echo 'var X = 1'; } >pkg/version/sillyvar.go
$ make
$ _output/go/bin/kubecfg -version
Kubernetes v0.2-29-gd916051e9db865-dirty
$ _output/go/bin/kubecfg -version=raw
version.Info{Major:"0", Minor:"2+", GitVersion:"v0.2-29-gd916051e9db865-dirty", GitCommit:"d916051e9db8650899acb9415a4e285e3e3a1f87", GitTreeState:"dirty"}
- Tag it v0.3 and build it:
$ git tag -a v0.3 -m 'Release Kubernetes v0.3'
$ make
$ _output/go/bin/kubecfg -version
Kubernetes v0.3
$ _output/go/bin/kubecfg -version=raw
version.Info{Major:"0", Minor:"3", GitVersion:"v0.3", GitCommit:"d916051e9db8650899acb9415a4e285e3e3a1f87", GitTreeState:"clean"}
- Built it from a tarball:
$ wget -O kubernetes.tgz https://api.github.com/repos/filbranden/kubernetes/tarball/version_string1
$ tar xvf kubernetes.tgz
$ cd filbranden-kubernetes-*/
$ make
$ _output/go/bin/kubecfg -version
Kubernetes v0.2-dev
$ _output/go/bin/kubecfg -version=raw
version.Info{Major:"0", Minor:"2+", GitVersion:"v0.2-dev", GitCommit:"", GitTreeState:"not a git tree"}
- Built it with `go get`:
# I need to prefetch the tree to replace the official tree with mine:
$ mkdir -p ${TMPDIR}/gopath/src/github.com/
$ ln -sf filbranden ${TMPDIR}/gopath/src/github.com/GoogleCloudPlatform
# Now run `go get` to build kubecfg:
$ GOPATH=${TMPDIR}/gopath go get github.com/filbranden/kubernetes/cmd/kubecfg
# Check the version:
$ ${TMPDIR}/gopath/bin/kubecfg -version
Kubernetes v0.2-dev
$ ${TMPDIR}/gopath/bin/kubecfg -version=raw
version.Info{Major:"0", Minor:"2+", GitVersion:"v0.2-dev", GitCommit:"", GitTreeState:"not a git tree"}

According to the plan listed in docs/releasing.md.
The gitMinor will keep using a "+" suffix instead for now.
Added a //TODO to deprecate gitMajor and gitMinor in a follow up.
Tested:
- Built it from the git tree:
$ make
$ _output/go/bin/kubecfg -version
Kubernetes version 0.2+, build 8d31eb03c11d4db64ae26809eef7f73070efd811
$ _output/go/bin/kubecfg -version=raw
version.Info{Major:"0", Minor:"2+", GitVersion:"v0.2-29-g8d31eb03c11d4d", GitCommit:"8d31eb03c11d4db64ae26809eef7f73070efd811", GitTreeState:"clean"}
- Built it with a direct `go install` (same as tarball):
$ GOPATH=${PWD}/_output/go:${PWD}/Godeps/_workspace go install $KUBE_GO_PACKAGE/cmd/kubecfg
$ _output/go/bin/kubecfg -version=raw
version.Info{Major:"0", Minor:"2+", GitVersion:"v0.2-dev", GitCommit:"", GitTreeState:"not a git tree"}
$ _output/go/bin/kubecfg -version
Kubernetes version 0.2+, build (unknown)
A follow up commit will address the output of the -version (without "raw") command to use gitVersion instead of Major + Minor.
