Functions

func CanReadFile

func CanReadFile(path string) bool

If the file represented by path exists and readable, return true otherwise return false.

func GenerateSelfSignedCert

func GenerateSelfSignedCert(certPath, keyPath string, ips []net.IP, alternateDNS []string) error

You may also specify additional subject alt names (either ip or dns names) for the certificate The certificate will be created with file mode 0644. The key will be created with file mode 0600. If the certificate or key files already exist, they will be overwritten. Any parent directories of the certPath or keyPath will be created as needed with file mode 0755.

func GetAlternateDNS

func GetAlternateDNS(domain string) []string

func Pad

func Pad(str string) string

func Retry

func Retry(attempts int, callback func() error) (err error)

func RetryAfter

func RetryAfter(attempts int, callback func() error, d time.Duration) (err error)

func Until

func Until(fn func() error, w io.Writer, name string, sleep time.Duration, done <-chan struct{})

Until endlessly loops the provided function until a message is received on the done channel. The function will wait the duration provided in sleep between function calls. Errors will be sent on provider Writer.

func ValidateOpenshiftMinVersion

func ValidateOpenshiftMinVersion(ver string) bool

func ValidateProxyURI

func ValidateProxyURI(uri string) bool

Types

type MultiError

type MultiError struct {
	Errors []error
}

func (*MultiError) Collect

func (m *MultiError) Collect(err error)

func (MultiError) ToError

func (m MultiError) ToError() error

type RealRunner

type RealRunner struct{}

func (RealRunner) Output

func (r RealRunner) Output(command string, args ...string) ([]byte, error)

the real runner for get the output as byte format

func (RealRunner) Run

func (r RealRunner) Run(command string, args ...string) error

the real runner for the actual program, actually execs the command

type Runner

type Runner interface {
	Run(string, ...string) error
	Output(string, ...string) ([]byte, error)
}
