Functions

func AdmissionControlReconciler added in v2.22.0 

func AdmissionControlReconciler(data *resources.TemplateData) reconciling.NamedConfigMapReconcilerFactory

func ApiserverInternalAllowReconciler added in v2.21.10 

func ApiserverInternalAllowReconciler() reconciling.NamedNetworkPolicyReconcilerFactory

ApiserverInternalAllowReconciler returns a func to create/update the apiserver-internal-allow egress policy. This policy is necessary since konnectivity-server (sidecar to kube-apiserver when konnectivity is enabled) needs to talk to the Kubernetes API to validate tokens coming from konnectivity-agent.

This was previously handled with a policy called cluster-external-addr-allow that allowed connection to the the external endpoint, but no reasoning for this design choice could be found in code comments or PR descriptions. Upstream itself uses localhost in an example (see https://github.com/kubernetes-sigs/apiserver-network-proxy/blob/a38752dc9884a1fc1c32652eacb38aed21e4ab25/examples/kubernetes/kubeconfig#L11), so the strong assumption here is that this was never necessary.

func AuditConfigMapReconciler added in v2.22.0 

func AuditConfigMapReconciler(data *resources.TemplateData) reconciling.NamedConfigMapReconcilerFactory

func CABundleReconciler added in v2.22.0

DNSAllowReconciler returns a func to create/update the apiserver DNS allow egress policy.

func DenyAllPolicyReconciler added in v2.22.0 

func DenyAllPolicyReconciler() reconciling.NamedNetworkPolicyReconcilerFactory

DenyAllPolicyReconciler returns a func to create/update the apiserver deny all egress policy.

func DeploymentReconciler added in v2.22.0 

func DeploymentReconciler(data *resources.TemplateData, enableOIDCAuthentication bool) reconciling.NamedDeploymentReconcilerFactory

DeploymentReconciler returns the function to create and update the API server deployment.

func EctdAllowReconciler added in v2.22.0

func EgressSelectorConfigReconciler added in v2.22.0 

func EgressSelectorConfigReconciler() reconciling.NamedConfigMapReconcilerFactory

EgressSelectorConfigReconciler returns function to create cm that contains egress selection configuration for apiserver to work with konnectivity proxy.

func EncryptionConfigurationSecretReconciler added in v2.22.0 

func EncryptionConfigurationSecretReconciler(data encryptionData) reconciling.NamedSecretReconcilerFactory

func EncryptionResourcesForDeletion added in v2.21.0 

func EncryptionResourcesForDeletion(namespace string) []ctrlruntimeclient.Object

func EtcdClientCertificateReconciler added in v2.22.0 

func EtcdClientCertificateReconciler(data etcdClientCertificateReconcilerData) reconciling.NamedSecretReconcilerFactory

EtcdClientCertificateReconciler returns a function to create/update the secret with the client certificate for authenticating against etcd.

func FluentBitSecretReconciler added in v2.22.0 

func FluentBitSecretReconciler(data *resources.TemplateData) reconciling.NamedSecretReconcilerFactory

FluentBitSecretReconciler returns a reconciling.NamedSecretReconcilerFactory for a secret that contains fluent-bit configuration for the audit-logs sidecar.

func FrontProxyClientCertificateReconciler added in v2.22.0 

func FrontProxyClientCertificateReconciler(data frontProxyClientCertificateReconcilerData) reconciling.NamedSecretReconcilerFactory

FrontProxyClientCertificateReconciler returns a function to create/update the secret with the client certificate for authenticating against extension apiserver.

func GetEnvVars 

func GetEnvVars(data kubeAPIServerEnvData) ([]corev1.EnvVar, error)

func IsRunningWrapper 

func IsRunningWrapper(data isRunningInitContainerData, specTemplate corev1.PodTemplateSpec, containersToWrap sets.Set[string], crdsToWaitFor ...string) (corev1.PodTemplateSpec, error)

IsRunningWrapper wraps the named containers in the pod with a check if the API server is reachable. This is achieved by copying a `http-prober` binary via an init container into an emptyDir volume, then mounting that volume onto all named containers and replacing the command with a call to the `http-prober` binary. The http prober binary gets the original command as serialized string and does an syscall.Exec onto it once the apiserver became reachable.

func KubeletClientCertificateReconciler added in v2.22.0 

func KubeletClientCertificateReconciler(data kubeletClientCertificateReconcilerData) reconciling.NamedSecretReconcilerFactory

KubeletClientCertificateReconciler returns a function to create/update a secret with the client certificate for the apiserver -> kubelet connection.

func MachineControllerWebhookAllowReconciler added in v2.22.0
