The old flag name doesn't make sense with the renamed API Priority and
Fairness feature, and it's still safe to change the flag since it hasn't done
anything useful in a released k8s version yet.
Kubernetes-commit: 711c1e17209cc410440eecd3723e7b4906ca0e42
- Add handlers for service account issuer metadata.
- Add option to manually override JWKS URI.
- Add unit and integration tests.
- Add a separate ServiceAccountIssuerDiscovery feature gate.
Additional notes:
- If not explicitly overridden, the JWKS URI will be based on
the API server's external address and port.
- The metadata server is configured with the validating key set rather
than the signing key set. This allows for key rotation because tokens
can still be validated by the keys exposed in the JWKs URL, even if the
signing key has been rotated (note this may still be a short window if
tokens have short lifetimes).
- The trust model of OIDC discovery requires that the relying party
fetch the issuer metadata via HTTPS; the trust of the issuer metadata
comes from the server presenting a TLS certificate with a trust chain
back to the from the relying party's root(s) of trust. For tests, we use
a local issuer (https://kubernetes.default.svc) for the certificate
so that workloads within the cluster can authenticate it when fetching
OIDC metadata. An API server cannot validly claim https://kubernetes.io,
but within the cluster, it is the authority for kubernetes.default.svc,
according to the in-cluster config.

From the listen godoc:
For TCP networks, if the host in the address parameter is empty or a
literal unspecified IP address, Listen listens on all available unicast
and anycast IP addresses of the local system.
Since the BindNetwork options is "tcp" by default, using an unspecified
address doesn't bind the listener to the IP family.
Kubernetes-commit: 05010d23ac7751a17aa26fb5cc011eb4f2127b1e
apiserver adds localhost to the alternateDNS field
if the bind address is 0.0.0.0.
This PR considers the IPv6 unspecified address too.
Kubernetes-commit: 29ec87f769c6494fad5c0a0c624efe2dc6eeab13
The old name is too broad, we wanted a name that is more specific to
the actual feature.
This is an alpha gate, and no release has yet associated any
functionality with this gate.
Kubernetes-commit: 76d090e30f917888c5882228f7261ed31a34a2ab
Also rename utilnet.ChooseBindAddress() to ResolveBindAddress(), to
better describe its functionality.

Reload SNI certificate cert and key file from disk every minute and notify
the dynamic certificate controller when they change, allowing serving
tls config to be updated.

Reload certificate cert and key file from disk every minute and notify
the dynamic certificate controller when they change, allowing serving
tls config to be updated.
Kubernetes-commit: 3f5fbfbfac281f40c11de2f57d58cc332affc37b
We create and use a dynamic certificate provider for the SNI serving
certificates. Currently we only use static serving certificate
providers, so the files are not reloaded, but we should be able to move
to a provider that is able to reload later on.
Kubernetes-commit: 84bc6b151d0726db0c737443874577f044e0e9c8
Currently we record request metrics during the normal request flow and
we also manually invoke `Record` in the timeout handler to record
timeouts. This means that we effectively double count whenever we
timeout. This PR renames the `Record` function to `RecordRequestError`
to more accurately reflect the intended side-effect of the function
call.

Kubernetes-commit: 4c6e7247878477a1f2efc26df7f141258010374f
We create and use a dynamic certificate provider for the main apiserver
serving certificates: SNI will be handled separately later. Currently we
only use static serving certificate providers, so the files are not
reloaded, but we should be able to move to a provider that is able to
reload later on.

This change updates NewPrefixTransformers to not short-circuit on
the first transformer that has a matching prefix. If the same type
of encryption ProviderConfiguration is used more than once, they
will share the same prefix. A failure in the first one should not
prevent a later match from being attempted.
Added TestCBCKeyRotationWithOverlappingProviders unit test to
prevent regressions. Note that this test explicitly exercises this
flow using an EncryptionConfiguration object as the structure of the
resulting transformer is an important part of the check.

If konnectivity service is enabled, the etcd client will now use it.
This did require moving a few methods to break circular dependencies.
Factored in feedback from lavalamp and wenjiaswe.

go fmt
make func private
refactor config_test
Two primary refactorings:
1. config test checkPath method is now each a distinct test
run (which makes it easier to see what is actually failing)
2. TestNewWithDelegate's root path check now parses the json output and
does a comparison against a list of expected paths (no more whitespace
and ordering issues when updating this test, yay).
go fmt
modify and simplify existing integration test for readyz/livez
simplify integration test
set default rbac policy rules for livez
rename a few functions and the entrypoint command line argument (and etcetera)
simplify interface for installing readyz and livez and make auto-register completion a bootstrapped check
untangle some of the nested functions, restructure the code

The previous HTTP compression implementation functioned as a filter, which
required it to deal with a number of special cases that complicated the
implementation.
Instead, when we write an API object to a response, handle only that one
case. This will allow a more limited implementation that does not impact
other code flows.
Also, to prevent excessive CPU use on small objects, compression is
disabled on responses smaller than 128Kb in size.

that does not support ipv6 or ipv4
