Functions

func IsSpecialMountType

func IsSpecialMountType(mntType string) bool

Types

type ContainerFS

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

ContainerFS is a vfs-like abstraction for operating on a container's filesystem without needing to actually create all the mounts and unmount them (which can be expensive).

func NewContainerFS

func NewContainerFS(spec *specs.Spec, executeContainer ExecuteContainerFunc) (*ContainerFS, error)

func (*ContainerFS) AnyPathExists

func (ctrFS *ContainerFS) AnyPathExists(paths []string) (bool, error)

func (*ContainerFS) DirIsEmpty

func (ctrFS *ContainerFS) DirIsEmpty(path string) (bool, error)

func (*ContainerFS) EvaluateSymlinks

func (ctrFS *ContainerFS) EvaluateSymlinks(name string) (string, error)

func (*ContainerFS) Exec

func (ctrFS *ContainerFS) Exec(ctx context.Context, args ...string) error

func (*ContainerFS) LookPath

func (ctrFS *ContainerFS) LookPath(cmd string) (string, error)

func (*ContainerFS) Lstat

func (ctrFS *ContainerFS) Lstat(name string) (fs.FileInfo, error)

func (*ContainerFS) MkdirAll

func (ctrFS *ContainerFS) MkdirAll(path string, perm fs.FileMode) (createdDir string, rerr error)

MkdirAll is like os.MkdirAll but returns the uppermost container parent dir that was created

func (*ContainerFS) MtimeOf

func (ctrFS *ContainerFS) MtimeOf(path string) (int64, error)

func (*ContainerFS) OSReleaseFileContains

func (ctrFS *ContainerFS) OSReleaseFileContains(ids [][]byte, idLikes [][]byte) (bool, error)

func (*ContainerFS) Open

func (ctrFS *ContainerFS) Open(name string) (fs.File, error)

func (*ContainerFS) OpenFile

func (ctrFS *ContainerFS) OpenFile(name string, flag int, perm fs.FileMode) (*os.File, error)

func (*ContainerFS) PathExists

func (ctrFS *ContainerFS) PathExists(path string) (bool, error)

func (*ContainerFS) ReadCABundleFile

func (ctrFS *ContainerFS) ReadCABundleFile(path string) (map[string]struct{}, error)

Returned map is keyed with the contents of each cert in the bundle, with all newlines stripped. The bundle file is presumed to have the format of each cert separated by a blank line.

func (*ContainerFS) ReadCustomCADir

func (ctrFS *ContainerFS) ReadCustomCADir(path string) (
	certsToFileName map[string]string,
	symlinks map[string]string,
	rerr error,
)

func (*ContainerFS) ReadDir

func (ctrFS *ContainerFS) ReadDir(name string) ([]fs.DirEntry, error)

func (*ContainerFS) ReadFile

func (ctrFS *ContainerFS) ReadFile(path string) ([]byte, error)

func (*ContainerFS) Readlink

func (ctrFS *ContainerFS) Readlink(name string) (string, error)

func (*ContainerFS) Remove

func (ctrFS *ContainerFS) Remove(path string) error

func (*ContainerFS) RemoveAll

func (ctrFS *ContainerFS) RemoveAll(path string) error

func (*ContainerFS) RemoveCertsFromCABundle

func (ctrFS *ContainerFS) RemoveCertsFromCABundle(path string, certs map[string]string) error

func (*ContainerFS) SetMtime

func (ctrFS *ContainerFS) SetMtime(path string, t int64) error

func (*ContainerFS) Stat

func (ctrFS *ContainerFS) Stat(name string) (fs.FileInfo, error)

func (*ContainerFS) Symlink

func (ctrFS *ContainerFS) Symlink(oldname, newname string) error

func (*ContainerFS) WriteFile

func (ctrFS *ContainerFS) WriteFile(path string, data []byte, perm fs.FileMode) error

type ExecuteContainerFunc

type ExecuteContainerFunc func(ctx context.Context, args ...string) error
