Constants ¶
const DefaultPathEnv = ""
DefaultPathEnv is deliberately empty on Windows as the default path will be set by the container. Docker has no context of what the default path should be.
Variables ¶
var ( // ErrNotSupportedPlatform means the platform is not supported. ErrNotSupportedPlatform = errors.New("platform and architecture is not supported") )
Functions ¶
func CreateEvent ¶
func CreateEvent(eventAttributes *syscall.SecurityAttributes, manualReset bool, initialState bool, name string) (handle syscall.Handle, err error)
CreateEvent implements win32 CreateEventW func in golang. It will create an event object.
func IsAbs ¶
IsAbs is a platform-specific wrapper for filepath.IsAbs. On Windows, golang filepath.IsAbs does not consider a path \windows\system32 as absolute as it doesn't start with a drive-letter/colon combination. However, in docker we need to verify things such as WORKDIR /windows/system32 in a Dockerfile (which gets translated to \windows\system32 when being processed by the daemon. This SHOULD be treated as absolute from a docker processing perspective.
func LUtimesNano ¶
LUtimesNano is not supported on platforms other than linux, freebsd and darwin.
func OpenEvent ¶
func OpenEvent(desiredAccess uint32, inheritHandle bool, name string) (handle syscall.Handle, err error)
OpenEvent implements win32 OpenEventW func in golang. It opens an event object.
func PulseEvent ¶
PulseEvent implements win32 PulseEvent func in golang.
func ResetEvent ¶
ResetEvent implements win32 ResetEvent func in golang.
Types ¶
type MemInfo ¶
type MemInfo struct {
// Total usable RAM (i.e. physical RAM minus a few reserved bits and the
// kernel binary code).
MemTotal int64
// Amount of free memory.
MemFree int64
// Total amount of swap space available.
SwapTotal int64
// Amount of swap space that is currently unused.
SwapFree int64
}
MemInfo contains memory statistics of the host system.
func ReadMemInfo ¶
ReadMemInfo retrieves memory statistics of the host system and returns a
MemInfo type.
type OSVersion ¶
OSVersion is a wrapper for Windows version information https://msdn.microsoft.com/en-us/library/windows/desktop/ms724439(v=vs.85).aspx
func GetOSVersion ¶
GetOSVersion gets the operating system version on Windows. Note that docker.exe must be manifested to get the correct version information.
type StatT ¶
type StatT struct {
// contains filtered or unexported fields
}
StatT type contains status of a file. It contains metadata like name, permission, size, etc about a file.
func Lstat ¶
Lstat calls os.Lstat to get a fileinfo interface back. This is then copied into our own locally defined structure. Note the Linux version uses fromStatT to do the copy back, but that not strictly necessary when already in an OS specific module.
