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.

This commit will be tagged with a v0.2 annotated git tag.
Tested:
- Created a git tag for it, built it and checked output of -version:
$ git tag -a -m 'Release Kubernetes v0.2' v0.2
$ make
hack/build-go.sh
Building local go components
$ _output/go/bin/kubecfg -version
Kubernetes version 0.2, build b47f9af5c9ea770973be1b001adaffbdfcb08618
$ _output/go/bin/kubecfg -version=raw
version.Info{Major:"0", Minor:"2", GitVersion:"v0.2", GitCommit:"b47f9af5c9ea770973be1b001adaffbdfcb08618", GitTreeState:"clean"}
- Made sure hack/test-go.sh and hack/test-cmd.sh still pass.
