type OCIManagerOption added in v0.6.0 

type OCIManagerOption func(context.Context, *ociManager) error

func WithContainerd added in v0.6.0 

func WithContainerd(ctx context.Context, addr, namespace string) OCIManagerOption

WithContainerd forces the use of a containerd handler by providing an address to the containerd daemon (whether UNIX socket or TCP socket) as well as the default namespace to operate within.
