Functions ¶
func CheckLocalDns ¶
CheckLocalDns looks into the /etc/resolv.conf, it returns true if there is a local nameserver or if there is no nameserver.
func CompareKernelVersion ¶
func CompareKernelVersion(a, b *KernelVersionInfo) int
Compare two KernelVersionInfo struct. Returns -1 if a < b, = if a == b, 1 it a > b
func CopyDirectory ¶
FIXME: this is deprecated by CopyWithTar in archive.go
func CopyEscapable ¶
Code c/c from io.Copy() modified to handle escape sequence
func Debugf ¶
func Debugf(format string, a ...interface{})
Debug function, if the debug flag is set, then display. Do nothing otherwise If Docker is in damon mode, also send the debug info on the socket
func FindCgroupMountpoint ¶
func GetReleaseVersion ¶
func GetReleaseVersion() string
func GetResolvConf ¶
GetResolvConf opens and read the content of /etc/resolv.conf. It returns it as byte slice.
func GetTotalUsedFds ¶
func GetTotalUsedFds() int
func Go ¶
Go is a basic promise implementation: it wraps calls a function in a goroutine, and returns a channel which will later return the function's return value.
func HumanDuration ¶
HumanDuration returns a human-readable approximation of a duration (eg. "About a minute", "4 hours ago", etc.)
func HumanSize ¶
HumanSize returns a human-readable approximation of a size using SI standard (eg. "44kB", "17MB")
func NewBufReader ¶
func NopWriteCloser ¶
func NopWriteCloser(w io.Writer) io.WriteCloser
func ParseRepositoryTag ¶
Get a repos name and returns the right reposName + tag The tag can be confusing because of a port in a repository name.
Ex: localhost.localdomain:5000/samalba/hipache:latest
func ProgressReader ¶
func ProgressReader(r io.ReadCloser, size int, output io.Writer, template []byte, sf *StreamFormatter) *progressReader
func TruncateID ¶
TruncateID returns a shorthand version of a string identifier for convenience. A collision with other shorthands is very unlikely, but possible. In case of a collision a lookup with TruncIndex.Get() will fail, and the caller will need to use a langer prefix, or the full-length Id.
Types ¶
type HTTPRequestDecorator ¶
type HTTPRequestDecorator interface {
// ChangeRequest() changes the request accordingly.
// The changed request will be returned or err will be non-nil
// if an error occur.
ChangeRequest(req *http.Request) (newReq *http.Request, err error)
}
HTTPRequestDecorator is used to change an instance of http.Request. It could be used to add more header fields, change body, etc.
func NewHTTPUserAgentDecorator ¶
func NewHTTPUserAgentDecorator(versions ...VersionInfo) HTTPRequestDecorator
type HTTPRequestFactory ¶
type HTTPRequestFactory struct {
// contains filtered or unexported fields
}
HTTPRequestFactory creates an HTTP request and applies a list of decorators on the request.
func NewHTTPRequestFactory ¶
func NewHTTPRequestFactory(d ...HTTPRequestDecorator) *HTTPRequestFactory
func (*HTTPRequestFactory) NewRequest ¶
func (self *HTTPRequestFactory) NewRequest(method, urlStr string, body io.Reader, d ...HTTPRequestDecorator) (*http.Request, error)
NewRequest() creates a new *http.Request, applies all decorators in the HTTPRequestFactory on the request, then applies decorators provided by d on the request.
type HTTPUserAgentDecorator ¶
type HTTPUserAgentDecorator struct {
// contains filtered or unexported fields
}
HTTPUserAgentDecorator appends the product/version to the user agent field of a request.
func (*HTTPUserAgentDecorator) ChangeRequest ¶
type JSONError ¶
type JSONMessage ¶
type KernelVersionInfo ¶
func GetKernelVersion ¶
func GetKernelVersion() (*KernelVersionInfo, error)
func (*KernelVersionInfo) String ¶
func (k *KernelVersionInfo) String() string
type StreamFormatter ¶
type StreamFormatter struct {
// contains filtered or unexported fields
}
func NewStreamFormatter ¶
func NewStreamFormatter(json bool) *StreamFormatter
func (*StreamFormatter) FormatError ¶
func (sf *StreamFormatter) FormatError(err error) []byte
func (*StreamFormatter) FormatProgress ¶
func (sf *StreamFormatter) FormatProgress(id, action, progress string) []byte
func (*StreamFormatter) FormatStatus ¶
func (sf *StreamFormatter) FormatStatus(id, format string, a ...interface{}) []byte
func (*StreamFormatter) Used ¶
func (sf *StreamFormatter) Used() bool
type StreamWriter ¶
type StreamWriter struct {
// contains filtered or unexported fields
}
type TruncIndex ¶
type TruncIndex struct {
// contains filtered or unexported fields
}
TruncIndex allows the retrieval of string identifiers by any of their unique prefixes. This is used to retrieve image and container IDs by more convenient shorthand prefixes.
func NewTruncIndex ¶
func NewTruncIndex() *TruncIndex
func (*TruncIndex) Add ¶
func (idx *TruncIndex) Add(id string) error
func (*TruncIndex) Delete ¶
func (idx *TruncIndex) Delete(id string) error
type VersionInfo ¶
VersionInfo is used to model entities which has a version. It is basically a tupple with name and version.
type WriteBroadcaster ¶
func NewWriteBroadcaster ¶
func NewWriteBroadcaster() *WriteBroadcaster
func (*WriteBroadcaster) AddWriter ¶
func (w *WriteBroadcaster) AddWriter(writer io.WriteCloser, stream string)
func (*WriteBroadcaster) CloseWriters ¶
func (w *WriteBroadcaster) CloseWriters() error
type WriteFlusher ¶
func NewWriteFlusher ¶
func NewWriteFlusher(w io.Writer) *WriteFlusher
