Constants ¶

const SddlAdministratorsLocalSystem = "D:P(A;OICI;GA;;;BA)(A;OICI;GA;;;SY)"

SddlAdministratorsLocalSystem is local administrators plus NT AUTHORITY\System.

Variables ¶

var (
	// ErrNotSupportedPlatform means the platform is not supported.
	ErrNotSupportedPlatform = errors.New("platform and architecture is not supported")

	// ErrNotSupportedOperatingSystem means the operating system is not supported.
	ErrNotSupportedOperatingSystem = errors.New("operating system is not supported")
)

var (
	// IsProcessAlive returns true if process with a given pid is running.
	//
	// Deprecated: use [process.Alive].
	IsProcessAlive = process.Alive

	// IsProcessZombie return true if process has a state with "Z"
	//
	// Deprecated: use [process.Zombie].
	//
	// TODO(thaJeztah): remove the Windows implementation in process once we remove this stub.
	IsProcessZombie = process.Zombie
)

Functions ¶

func Chtimes ¶

func Chtimes(name string, atime time.Time, mtime time.Time) error

Chtimes changes the access time and modified time of a file at the given path. If the modified time is prior to the Unix Epoch (unixMinTime), or after the end of Unix Time (unixEpochTime), os.Chtimes has undefined behavior. In this case, Chtimes defaults to Unix Epoch, just in case.

func ContainerdRuntimeSupported ¶

func ContainerdRuntimeSupported() bool

ContainerdRuntimeSupported returns true if the use of containerd runtime is supported.

func DefaultPathEnv ¶

func DefaultPathEnv(os string) string

DefaultPathEnv is unix style list of directories to search for executables. Each directory is separated from the next by a colon ':' character . For Windows containers, an empty string is returned as the default path will be set by the container, and Docker has no context of what the default path should be.

Deprecated: use oci.DefaultPathEnv

func EscapeArgs ¶

func EscapeArgs(args []string) string

EscapeArgs makes a Windows-style escaped command line from a set of arguments

func InitContainerdRuntime ¶

func InitContainerdRuntime(cdPath string)

InitContainerdRuntime sets whether to use containerd for runtime on Windows.

func IsAbs ¶

func IsAbs(path string) bool

IsAbs is a platform-agnostic 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 IsOSSupported ¶

func IsOSSupported(os string) bool

IsOSSupported determines if an operating system is supported by the host.

func KillProcess ¶

func KillProcess(pid int)

KillProcess force-stops a process.

Deprecated: use process.Kill.

func LUtimesNano ¶

func LUtimesNano(path string, ts []syscall.Timespec) error

LUtimesNano is only supported on linux and freebsd.

func Lgetxattr ¶

func Lgetxattr(path string, attr string) ([]byte, error)

Lgetxattr is not supported on platforms other than linux.

func Lsetxattr ¶

func Lsetxattr(path string, attr string, data []byte, flags int) error

Lsetxattr is not supported on platforms other than linux.

func Mkdev ¶

func Mkdev(major int64, minor int64) uint32

Mkdev is not implemented on Windows.

func MkdirAll ¶

func MkdirAll(path string, _ os.FileMode) error

MkdirAll is a custom version of os.MkdirAll that is volume path aware for Windows. It can be used as a drop-in replacement for os.MkdirAll.

func MkdirAllWithACL ¶

func MkdirAllWithACL(path string, _ os.FileMode, sddl string) error

MkdirAllWithACL is a custom version of os.MkdirAll modified for use on Windows so that it is both volume path aware, and can create a directory with an appropriate SDDL defined ACL.

func Mknod ¶

func Mknod(path string, mode uint32, dev int) error

Mknod is not implemented on Windows.

func ReadMemInfo ¶

func ReadMemInfo() (*meminfo.Memory, error)

ReadMemInfo retrieves memory statistics of the host system and returns a MemInfo type.

Deprecated: use meminfo.Read.

Types ¶

type MemInfo ¶

type MemInfo = meminfo.Memory

MemInfo contains memory statistics of the host system.

Deprecated: use meminfo.Memory.

type StatT ¶

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

StatT type contains status of a file. It contains metadata like permission, size, etc about a file.

func Lstat ¶

func Lstat(path string) (*StatT, error)

Lstat calls os.Lstat to get a fileinfo interface back. This is then copied into our own locally defined structure.

func Stat ¶

func Stat(path string) (*StatT, error)

Stat takes a path to a file and returns a system.StatT type pertaining to that file.

Throws an error if the file does not exist

func (StatT) Mode ¶

func (s StatT) Mode() os.FileMode

Mode returns file's permission mode.

func (StatT) Mtim ¶

func (s StatT) Mtim() time.Time

Mtim returns file's last modification time.

func (StatT) Size ¶

func (s StatT) Size() int64

Size returns file's size.
