Functions

func GetAddressFromMasterNode

func GetAddressFromMasterNode(ctx context.Context, cl client.Client) (address string, err error)

GetAddressFromMasterNode returns the API Server address using the IP of the master node of this cluster. The port is always defaulted to 6443.

func GetURL

func GetURL(ctx context.Context, cl client.Client, addressOverride string) (string, error)

GetURL retrieves the API server URL either from the configuration or selecting the IP address of a master node (with port 6443).

func InitFlags

func InitFlags(flagset *flag.FlagSet)

InitFlags initializes the flags to configure the API server parameters.

func RetrieveAPIServerCA

func RetrieveAPIServerCA(restcfg *rest.Config, caOverride []byte, trustedCA bool) ([]byte, error)

RetrieveAPIServerCA retrieves the APIServerCA, either from the CAData in the restConfig, or reading from the CAFile.

Types

type Config

type Config struct {
	// The address of the Kubernetes API Server, advertised to the peering clusters.
	Address string

	// Whether the Kubernetes API Server is exposed through a trusted certification authority,
	// which does not need to be explicitly advertised.
	TrustedCA bool

	// The certification authority trusted by the API server.
	CA string
}

Config defines the configuration parameters to contact the Kubernetes API server.

func GetConfig

func GetConfig() Config

GetConfig returns the API server configuration populated based on the command line parameters.

func (*Config) Complete

func (c *Config) Complete(restcfg *rest.Config, cl client.Client) (err error)

Complete completes the retrieval of the configuration, defaulting the fields if not set.
