For the YAML examples, make the indentation consistent
by starting with a space and following with a TAB.
Also adjust the indentation of some fields to place them under
the right YAML field parent - e.g. ignorePreflightErrors
is under nodeRegistration.
- Modify VerifyUnmarshalStrict to use serializer/json instead
of sigs.k8s.io/yaml. In strict mode, the serializers
in serializer/json use the new sigs.k8s.io/json library
that also catches case sensitive errors for field names -
e.g. foo vs Foo. Include test case for that in strict/testdata.
- Move the hardcoded schemes to check to the side of the
caller - i.e. accept a slice of runtime.Scheme.
- Move the klog warnings outside of VerifyUnmarshalStrict
and make them the responsibility of the caller.
- Call VerifyUnmarshalStrict when downloading the configuration
from kubeadm-config or the kube-proxy or kubelet-config CMs.
This validation is useful if the user has manually patched the CMs.
The apiserver owns and manages the kubernetes.default service.
It has 3 different options to reconcile the endpoints that belong to
that service:
- None: endpoints are handled by an external party.
- MasterCount: legacy, it reconciles based on the endpoints generated
and a flag specifying the number of master on the cluster.
- Lease: default since 1.11, each apiserver writes a lease in etcd
and renews periodically, the endpoints are generated based on the
existing leases.
It seems that when the default was set for the lease reconciler, the
controlplane code wasn't updated and kept using the master count
reconciler.
This also starts the deprecation of the master count reconciler in
favor of the lease reconciler.
The legacy naming "kubelet-config-x.yy" is no longer the
default behavior. Rename instances in documentation and comments
of "kubelet-config-x.yy" to "kubelet-config".
- Graduate the feature gate to Beta and enable it by default.
- Pre-set the default value for UnversionedKubeletConfigMap
to "true" in test/e2e_kubeadm.
- Fix a couple of typos in "tolerate" introduced in the PR that
added the FG in 1.23.
Compare with two pointers will always show that they are different value,
so it will always print the warning message.
