func (*Container) GetResourcePath added in v1.7.0 

func (container *Container) GetResourcePath(path string) (string, error)

Evaluates `path` in the scope of the container's basefs, with proper path sanitisation. Symlinks are all scoped to the basefs of the container, as though the container's basefs was `/`.

The basefs of a container is the host-facing path which is bind-mounted as `/` inside the container. This method is essentially used to access a particular path inside the container as though you were a process in that container.

NOTE: The returned path is *only* safely scoped inside the container's basefs 

if no component of the returned path changes (such as a component
symlinking to a different path) between using this method and using the
path. See symlink.FollowSymlinkInScope for more details.

func (*Container) GetRootResourcePath added in v1.7.0 

func (container *Container) GetRootResourcePath(path string) (string, error)

Evaluates `path` in the scope of the container's root, with proper path sanitisation. Symlinks are all scoped to the root of the container, as though the container's root was `/`.

The root of a container is the host-facing configuration metadata directory. Only use this method to safely access the container's `container.json` or other metadata files. If in doubt, use container.GetResourcePath.

NOTE: The returned path is *only* safely scoped inside the container's root 

if no component of the returned path changes (such as a component
symlinking to a different path) between using this method and using the
path. See symlink.FollowSymlinkInScope for more details.
