Functions

func AppendAuthenticator

func AppendAuthenticator(config *clientcmdapi.Config, clusterMeta *api.ClusterMeta, authenticatorCMD, roleARN, profile string)

AppendAuthenticator appends the AWS IAM authenticator, and if profile is non-empty string it sets AWS_PROFILE environment variable also

func AuthenticatorCommands

func AuthenticatorCommands() []string

AuthenticatorCommands returns all of authenticator commands

func AutoPath

func AutoPath(name string) string

AutoPath returns the path for the auto-generated kubeconfig

func DefaultPath

func DefaultPath() string

DefaultPath defines the default path

func LookupAuthenticator

func LookupAuthenticator() (string, bool)

LookupAuthenticator looks up an available authenticator

func MaybeDeleteConfig

func MaybeDeleteConfig(meta *api.ClusterMeta)

MaybeDeleteConfig will delete the auto-generated kubeconfig, if it exists

func NewForKubectl

func NewForKubectl(spec *api.ClusterConfig, username, roleARN, profile string) *clientcmdapi.Config

NewForKubectl creates configuration for a user with kubectl by configuring a suitable authenticator and respecting provider settings

func NewForUser

func NewForUser(spec *api.ClusterConfig, username string) *clientcmdapi.Config

NewForUser returns a Config suitable for a user by respecting provider settings

func Write

func Write(path string, newConfig clientcmdapi.Config, setContext bool) (string, error)

Write will write Kubernetes client configuration to a file. If path isn't specified then the path will be determined by client-go. If file pointed to by path doesn't exist it will be created. If the file already exists then the configuration will be merged with the existing file.
