Functions

func CacheParent

func CacheParent() string

CacheParent returns a cache parent for --mount=type=cache

func GetBindMount

func GetBindMount(ctx *types.SystemContext, args []string, contextDir string, store storage.Store, imageMountLabel string, additionalMountPoints map[string]internal.StageMountDetails, workDir string) (specs.Mount, string, error)

GetBindMount parses a single bind mount entry from the --mount flag. Returns specifiedMount and a string which contains name of image that we mounted otherwise its empty. Caller is expected to perform unmount of any mounted images

func GetCacheMount

func GetCacheMount(args []string, store storage.Store, imageMountLabel string, additionalMountPoints map[string]internal.StageMountDetails, workDir string) (specs.Mount, *lockfile.LockFile, error)

GetCacheMount parses a single cache mount entry from the --mount flag.

If this function succeeds and returns a non-nil *lockfile.LockFile, the caller must unlock it (when??).

func GetTmpfsMount

func GetTmpfsMount(args []string) (specs.Mount, error)

GetTmpfsMount parses a single tmpfs mount entry from the --mount flag

func GetVolumes

func GetVolumes(ctx *types.SystemContext, store storage.Store, volumes []string, mounts []string, contextDir string, workDir string) ([]specs.Mount, []string, []*lockfile.LockFile, error)

GetVolumes gets the volumes from --volume and --mount

If this function succeeds, the caller must unlock the returned *lockfile.LockFile s if any (when??).

func UnlockLockArray

func UnlockLockArray(locks []*lockfile.LockFile)

UnlockLockArray is a helper for cleaning up after GetVolumes and the like.
