func Mount ¶

func Mount(ctx context.Context, basePaths []string, upperdirPath, workdirPath, target string, readonly bool) (err error)

Mount creates an overlay mount with `basePaths` at `target`.

If `upperdirPath != ""` the path will be created. On mount failure the created `upperdirPath` will be automatically cleaned up.

If `workdirPath != ""` the path will be created. On mount failure the created `workdirPath` will be automatically cleaned up.

Always creates `target`. On mount failure the created `target` will be automatically cleaned up.

func MountLayer ¶ added in v0.10.0

func MountLayer(
	ctx context.Context,
	layerPaths []string,
	upperdirPath, workdirPath, rootfsPath string,
	readonly bool,
) (err error)

MountLayer first enforces the security policy for the container's layer paths and then calls Mount to mount the layer paths as an overlayfs.
