way to attach/interact with a running container?

[nravic]

Hello,

I was wondering if there's a way to attach to an already running container spawned by a tool like Podman or Docker. Something like:

docker run example-container, and then using libcontainer be able to get access to example-container (to look at state, checkpoint/restore or run a process).

More specifically, can you use something like container.Load

runc/libcontainer/factory_linux.go

Line 117 in 56b01e7

func Load(root, id string) (*Container, error) {

where id is the id of a container spawned by a docker or podman cli?
