- Factor out token constants to kubeadmconstants.
- Move cmd/kubeadm/app/util/{,token/}tokens.go
- Use the token-id, token-secret, etc constants provided by the bootstrapapi package
- Move cmd/kubeadm/app/master/tokens.go to cmd/kubeadm/app/phases/token/csv.go
This refactor basically makes it possible to hook up kubeadm to the BootstrapSigner controller later on
Some imports dont exist yet (or so it seems) in client-go (examples
being:
- "k8s.io/kubernetes/pkg/api/validation"
- "k8s.io/kubernetes/pkg/util/initsystem"
- "k8s.io/kubernetes/pkg/util/node"
one change in kubelet to import to client-go
Adds kubeadm subcommands to create, list, and delete bootstrap tokens.
Tokens can be created with a TTL duration, or 0 for tokens that will not
expire. The create command can also be used to specify your own token
(for use when bootstrapping masters and nodes in parallel), or update an
existing token's secret or ttl.
Marked "ex" for experimental for now as the boostrap controllers are not
yet hooked up in core.
Now, defaults can be pointing to "stable" and users will always get
latest available stable build of Kubernetes via kubeadm.
There is no need anymore to hardcode version string inside kubeadm
binary.
It is also possible to use labels like "latest" or point to exact
branch: "stable-1.4"
Previously, GetEnvParams (now called SetEnvParams) had no way of being altered unless
it was through enviroment variables. These changes allow for a global
EnvParam to be set and also altered while still initally getting their value from
set enviroment variables. This change is especially helpful for testing
(see kubeadm/app/util/kubeconfig_test.go).
