Constants ¶
const ( StdWriterPrefixLen = 8 StdWriterFdIndex = 0 StdWriterSizeIndex = 4 )
Variables ¶
var ( IAMSTATIC bool // whether or not Docker itself was compiled statically via ./hack/make.sh binary INITSHA1 string // sha1sum of separate static dockerinit, if Docker itself was compiled dynamically via ./hack/make.sh dynbinary INITPATH string // custom location to search for a valid dockerinit binary (available for packagers as a last resort escape hatch) )
var ErrInvalidStdHeader = errors.New("Unrecognized input header")
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 DockerInitPath ¶
Figure out the path of our dockerinit (which may be SelfPath())
func GetCallerName ¶
GetCallerName introspects the call stack and returns the name of the function `depth` levels down in the stack.
func GetNameserversAsCIDR ¶
GetNameserversAsCIDR returns nameservers (if any) listed in /etc/resolv.conf as CIDR blocks (e.g., "1.2.3.4/32") This function's output is intended for net.ParseCIDR
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 IsClosedError ¶
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 RAMInBytes ¶
Parses a human-readable string representing an amount of RAM in bytes, kibibytes, mebibytes or gibibytes, and returns the number of bytes, or -1 if the string is unparseable. Units are case-insensitive, and the 'b' suffix is optional.
func RandomString ¶
func RandomString() string
func SelfPath ¶
func SelfPath() string
Figure out the absolute path of our own binary (if it's still around).
func ShellQuoteArguments ¶
Take a list of strings and escape them so they will be handled right when passed as arguments to an program via a shell
func StdCopy ¶
StdCopy is a modified version of io.Copy.
StdCopy will demultiplex `src`, assuming that it contains two streams, previously multiplexed together using a StdWriter instance. As it reads from `src`, StdCopy will write to `dstout` and `dsterr`.
StdCopy will read until it hits EOF on `src`. It will then return a nil error. In other words: if `err` is non nil, it indicates a real underlying error.
`written` will hold the total number of bytes written to `dstout` and `dsterr`.
func StripComments ¶
StripComments parses input into lines and strips away comments.
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 DependencyGraph ¶
type DependencyGraph struct {
// contains filtered or unexported fields
}
func NewDependencyGraph ¶
func NewDependencyGraph() DependencyGraph
func (*DependencyGraph) AddDependency ¶
func (graph *DependencyGraph) AddDependency(node, to string) error
func (*DependencyGraph) GenerateTraversalMap ¶
func (graph *DependencyGraph) GenerateTraversalMap() ([][]string, error)
The magic happens here ::
func (*DependencyGraph) NewNode ¶
func (graph *DependencyGraph) NewNode(id string) string
type DependencyNode ¶
type DependencyNode struct {
// contains filtered or unexported fields
}
func (*DependencyNode) Degree ¶
func (node *DependencyNode) Degree() int
type Fataler ¶
type Fataler interface {
Fatal(args ...interface{})
}
A common interface to access the Fatal method of both testing.B and testing.T.
type KernelVersionInfo ¶
func GetKernelVersion ¶
func GetKernelVersion() (*KernelVersionInfo, error)
func ParseRelease ¶
func ParseRelease(release string) (*KernelVersionInfo, error)
func (*KernelVersionInfo) String ¶
func (k *KernelVersionInfo) String() string
type StatusError ¶
An StatusError reports an unsuccessful exit by a command.
func (*StatusError) Error ¶
func (e *StatusError) Error() string
type StdType ¶
type StdType [StdWriterPrefixLen]byte
type StdWriter ¶
func NewStdWriter ¶
NewStdWriter instanciates a new Writer. Everything written to it will be encapsulated using a custom format, and written to the underlying `w` stream. This allows multiple write streams (e.g. stdout and stderr) to be muxed into a single connection. `t` indicates the id of the stream to encapsulate. It can be utils.Stdin, utils.Stdout, utils.Stderr.
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 User ¶
type User struct {
Uid string // user id
Gid string // primary group id
Username string
Name string
HomeDir string
}
func UserLookup ¶
UserLookup check if the given username or uid is present in /etc/passwd and returns the user struct. If the username is not found, an error is returned.
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
