Add feature gate ServiceIPStaticSubrange to enable a new strategy
in the Service IP allocators, so the IP range is is subdivided and
dynamic allocated addresses are allocated preferently from the
upper range.
Implement a new bitmap allocator using an allocation strategy that accepts
and offset and subdivides the range based on this offset, prioritizing the
upper range for dynamic allocation.
When using a legacy cloud provider, if kubelet is passed a node address
in --node-ip it will use this address in preference out the the
addresses by the cloud provider.
When using an external cloud provider, kubelet will annotate the Node
with the first --node-ip for use by the cloud provider. The cloud
provider validates this annotation but does not otherwise use it,
meaning that --node-ip has no effect.
This change moves the node address filtering code from kubelet to
component-helpers and updates both kubelet and cloud-provider to use it.
There is no functional change to kubelet, but cloud-provider now honours
kubelet's --node-ip.
Remove the comment "As of v1.22, this field is beta and is controlled
via the CSRDuration feature gate" from the expirationSeconds field's
godoc.
Mark the "CSRDuration" feature gate as GA in 1.24, lock its value to
"true", and remove the various logic which handled when the gate was
"false".
Update conformance test to check that the CertificateSigningRequest's
Spec.ExpirationSeconds field is stored, but do not check if the field
is honored since this functionality is optional.
Rather than lazily computing and then caching the endpoint chain name
because we don't have the right information at construct time, just
pass the right information at construct time and compute the chain
name then.
Now that we don't have to always append all of the iptables args into
a single array, there's no reason to have LocalTrafficDetector take in
a set of args to prepend to its own output, and also not much point in
having it write out the "-j CHAIN" by itself either.
This change updates the generic webhook logic to use a rest.Config
as its input instead of a kubeconfig file. This exposes all of the
rest.Config knobs to the caller instead of the more limited set
available through the kubeconfig format. This is useful when this
code is being used as a library outside of core Kubernetes. For
example, a downstream consumer may want to override the webhook's
internals such as its TLS configuration.
