Kubeadm types

These types were copied in from kubernetes/kubernetes.

The types found in kubernetes/kubernetes are incompatible with controller-gen@v0.2.

controller-gen@v0.2 requires that all fields of all embedded types have json struct tags and kubeadm types are missing a few.

If the kubeadm types ever escape kubernetes/kubernetes then we will adopt those assuming the types do all have json struct tags.

Functions

func KubeVersionToKubeadmAPIGroupVersion

func KubeVersionToKubeadmAPIGroupVersion(v semver.Version) (schema.GroupVersion, error)

KubeVersionToKubeadmAPIGroupVersion maps a Kubernetes version to the correct Kubeadm API Group supported.

func MarshalClusterConfigurationForVersion

func MarshalClusterConfigurationForVersion(clusterConfiguration *bootstrapv1.ClusterConfiguration, version semver.Version) (string, error)

MarshalClusterConfigurationForVersion converts a Cluster API ClusterConfiguration type to the kubeadm API type for the given Kubernetes Version. NOTE: This assumes Kubernetes Version equals to kubeadm version.

func MarshalClusterStatusForVersion

func MarshalClusterStatusForVersion(clusterStatus *bootstrapv1.ClusterStatus, version semver.Version) (string, error)

MarshalClusterStatusForVersion converts a Cluster API ClusterStatus type to the kubeadm API type for the given Kubernetes Version. NOTE: This assumes Kubernetes Version equals to kubeadm version.

func MarshalInitConfigurationForVersion

func MarshalInitConfigurationForVersion(clusterConfiguration *bootstrapv1.ClusterConfiguration, initConfiguration *bootstrapv1.InitConfiguration, version semver.Version) (string, error)

MarshalInitConfigurationForVersion converts a Cluster API InitConfiguration type to the kubeadm API type for the given Kubernetes Version. NOTE: This assumes Kubernetes Version equals to kubeadm version.

func MarshalJoinConfigurationForVersion

func MarshalJoinConfigurationForVersion(clusterConfiguration *bootstrapv1.ClusterConfiguration, joinConfiguration *bootstrapv1.JoinConfiguration, version semver.Version) (string, error)

MarshalJoinConfigurationForVersion converts a Cluster API JoinConfiguration type to the kubeadm API type for the given Kubernetes Version. NOTE: This assumes Kubernetes Version equals to kubeadm version.

func UnmarshalClusterConfiguration

func UnmarshalClusterConfiguration(yaml string) (*bootstrapv1.ClusterConfiguration, error)

UnmarshalClusterConfiguration tries to translate a Kubeadm API yaml back to the Cluster API ClusterConfiguration type. NOTE: The yaml could be any of the known formats for the kubeadm ClusterConfiguration type.

func UnmarshalClusterStatus

func UnmarshalClusterStatus(yaml string) (*bootstrapv1.ClusterStatus, error)

UnmarshalClusterStatus tries to translate a Kubeadm API yaml back to the Cluster API ClusterStatus type. NOTE: The yaml could be any of the known formats for the kubeadm ClusterStatus type.

func UnmarshalInitConfiguration

func UnmarshalInitConfiguration(yaml string, clusterConfiguration *bootstrapv1.ClusterConfiguration) (*bootstrapv1.InitConfiguration, error)

UnmarshalInitConfiguration tries to translate a Kubeadm API yaml back to the InitConfiguration type. NOTE: The yaml could be any of the known formats for the kubeadm InitConfiguration type.

func UnmarshalJoinConfiguration

func UnmarshalJoinConfiguration(yaml string, clusterConfiguration *bootstrapv1.ClusterConfiguration) (*bootstrapv1.JoinConfiguration, error)

UnmarshalJoinConfiguration tries to translate a Kubeadm API yaml back to the JoinConfiguration type. NOTE: The yaml could be any of the known formats for the kubeadm JoinConfiguration type.

Types

type ConvertibleFromClusterConfiguration

type ConvertibleFromClusterConfiguration interface {
	ConvertFromClusterConfiguration(clusterConfiguration *bootstrapv1.ClusterConfiguration) error
}

ConvertibleFromClusterConfiguration defines capabilities of a type that during conversions gets values from ClusterConfiguration. NOTE: this interface is specifically designed to handle fields migrated from ClusterConfiguration to Init and JoinConfiguration in the kubeadm v1beta4 API version.

type ConvertibleToClusterConfiguration

type ConvertibleToClusterConfiguration interface {
	ConvertToClusterConfiguration(clusterConfiguration *bootstrapv1.ClusterConfiguration) error
}

ConvertibleToClusterConfiguration defines capabilities of a type that during conversions sets values to ClusterConfiguration. NOTE: this interface is specifically designed to handle fields migrated from ClusterConfiguration to Init and JoinConfiguration in the kubeadm v1beta4 API version.
