Functions

func CIDRToIPAndNetMask

func CIDRToIPAndNetMask(ipv4 string) (string, string, int, error)

func CreateMachineCloudInitSecret

func CreateMachineCloudInitSecret(ctx context.Context, userdata, machineName string, client ctrlruntimeclient.Client) error

func ExtractAPIServerToken

func ExtractAPIServerToken(ctx context.Context, client ctrlruntimeclient.Client) (string, error)

func ExtractTokenAndAPIServer

func ExtractTokenAndAPIServer(ctx context.Context, userdata string, client ctrlruntimeclient.Client) (token string, apiServer string, err error)

func RemoveFinalizerOnInstanceNotFound

func RemoveFinalizerOnInstanceNotFound(finalizer string,
	machine *v1alpha1.Machine,
	provider *cloudprovidertypes.ProviderData) (bool, error)

RemoveFinalizerOnInstanceNotFound checks whether a finalizer exists and removes it on demand.

func SetCABundleFile

func SetCABundleFile(filename string) error

SetCABundleFile reads a PEM-encoded file and replaces the current global CABundle with a new one. The file must contain at least one valid certificate.

Types

type HTTPClientConfig

type HTTPClientConfig struct {
	// LogPrefix is prepended to request/response logs
	LogPrefix string
	// Global timeout used by the client
	Timeout time.Duration
}

func (HTTPClientConfig) New

func (c HTTPClientConfig) New() http.Client

New return a custom HTTP client that allows for logging HTTP request and response information.

type LogRoundTripper

type LogRoundTripper struct {
	// contains filtered or unexported fields
}

LogRoundTripper is used to log information about requests and responses that may be useful for debugging purposes. Note that setting log level >5 results in full dumps of requests and responses, including sensitive invormation (e.g. Authorization header).

func (*LogRoundTripper) RoundTrip

func (lrt *LogRoundTripper) RoundTrip(request *http.Request) (*http.Response, error)
