Move the defaulting of the BootstrapToken type inside the
bootstraptoken/v1 package. This prevents an error where
codegen complains that a defaulter for the type exists in both
the kubeadm v1beta3 and v1beta4.
Adapt kubeadm code to use the defaulter function and constants
that were moved to bootstraptoken/v1.
NOTE: technically this is a breaking change for direct users of
v1beta3/SetDefaults_BootstrapToken().
- drop versions < 1.22 in the etcd map
- use 3.5.9-0 for >= 1.22 versions
- make the minimum version for external etcd 3.4.13-4 and max 3.5.9-0
- update images_test to not rely on a pinned etcd version in tests
note: the image 3.4.18-0 was never released in registry.k8s.io!
The path module has a few different functions:
Clean, Split, Join, Ext, Dir, Base, IsAbs. These functions do not
take into account the OS-specific path separator, meaning that they
won't behave as intended on Windows.
For example, Dir is supposed to return all but the last element of the
path. For the path "C:\some\dir\somewhere", it is supposed to return
"C:\some\dir\", however, it returns ".".
Instead of these functions, the ones in filepath should be used instead.
Currently, there are some unit tests that are failing on Windows due to
various reasons:
- filepath.IsAbs does not consider "/" or "\" as absolute paths, even
though files can be addressed as such.
- paths not properly joined (filepath.Join should be used).
- files not closed, which means that they cannot be removed / renamed.
- some assertions fail due to slashes / backslashes not matching.
- backslashes need to be escaped in yaml files, or put between ''
instead of "".
- lock the FG to true by default
- cleanup wrappers and logic related to versioned vs unversioned
naming of API objects (CMs and RBAC)
- update unit tests
Change the default container runtime CRI socket endpoint to the
one of containerd. Previously it was the one for Docker
- Rename constants.DefaultDockerCRISocket to DefaultCRISocket
- Make the constants files include the endpoints for all supported
container runtimes for Unix/Windows.
- Update unit tests related to docker runtime testing.
- In kubelet/flags.go hardcode the legacy docker socket as a check
to allow kubeadm 1.24 to run against kubelet 1.23 if the user
explicitly sets the criSocket field to "npipe:////./pipe/dockershim"
on Windows or "unix:///var/run/dockershim.sock" on Linux.
- Update defaults for v1beta2 and 3 to have URL scheme
- Raname DefaultUrlScheme to DefaultContainerRuntimeURLScheme
- Prepend a missing URL scheme to user sockets and warn them
that this might not be supported in the future
- Update socket validation to exclude IsAbs() testing
(This is broken on Windows). Assume the path is not empty and has
URL scheme at this point (validation happens after defaulting).
- Use net.Dial to open Unix sockets
- Update all related unit tests

Add the UnversionedKubeletConfigMap feature gate that can
be used to control legacy vs new behavior for naming the
default configmap used to store the KubeletConfiguration.
Update related unit tests.
