one test also proved it did not call the internet
but this was not fool proof as it did not return a string
and thus could be called with something expecting to fail.
updated the network calls to be package local so tests could pass their
own implementation. A public interface was not provided as it would not
be likely this would ever be needed or wanted.
When a kubeconfig file is read from disk it may lack the
propper mapping between contexts and clusters.
In such a case the kubeconfig phase backend will panic,
without throwing a sensible error.
Add nil checks for a couple of map operations in
validateKubeConfig().
add startup sequence duration and readyz endpoint
add rbac bootstrapping policy for readyz
add integration test around grace period and readyz
rename startup sequence duration flag
copy health checks to fields
rename health-check installed boolean, refactor clock injection logic
cleanup clock injection code
remove todo about poststarthook url registration from healthz
- Added scripts for update and verify
- golang AST code for scanning and fixing imports
- default regex allows it to run on just test/e2e.* file paths
- exclude verify-import-aliases.sh from running in CI jobs

This patch refactors pkg/util/mount to be more usable outside of
Kubernetes. This is done by refactoring mount.Interface to only contain
methods that are not K8s specific. Methods that are not relevant to
basic mount activities but still have OS-specific implementations are
now found in a mount.HostUtils interface.
This helper is used in tests and pulls in unnecessary dependency, which should
not be used if kubeadm is to move to staging.
Replace with direct use of the GroupResource type.

ValidateDNS1123Subdomain is a simple wrapper around IsDNS1123Subdomain, however
it's the only reason for us to pull k8s.io/kubernetes/pkg/apis/core/validation
as a dependency.
To avoid unnecessary dependencies, replace the use of ValidateDNS1123Subdomain
with IsDNS1123Subdomain.

RBAC construction helpers are part of the Kubernetes internal APIs. As such,
we cannot use them once we move to staging.
Hence, replace their use with manual RBAC rule construction.

During the control plane joins, sometimes the control plane returns an
expected error when trying to download the `kubeadm-config` ConfigMap.
This is a workaround for this issue until the root cause is completely
identified and fixed.
Ideally, this commit should be reverted in the near future.
kube-controller-manager.
If a service CIDR that overlaps with the cluster CIDR is
specified to kube-controller-manager then kube-controller-
manager will incorrectly allocate node CIDRs that overlap
with the service CIDR. The fix ensure that kubeadm
maps the --service-cidr to --service-cluster-ip-range for use
by kube-controller-manager.
As per docs, --allocate-node-cidrs must be true for
--service-cluster-ip-range to be considered. It does not make
sense for --cluster-cidr to be unspecified but for
--service-cluster-ip-range and --allocate-node-cidrs to be
set, since the purpose of these options is to have the
controller-manager do the per node CIDR allocation. Also
note that --service-cluster-ip-range is passed to the
api-server, so the presence of *just*
--service-cluster-ip-range should not imply that
--allocate-node-cidrs should be true.
