cntr

a container debugging tool based on FUSE mount

Description

cntr mounts the file system from one container or the host into the target container, by creating a nested container with the help of a FUSE filesystem. This allows to ship minimal runtime image in production and limit the surface for exploits.

Natively supported: docker, podman, LXC, LXD, rkt, systemd-nspawn, containerd; For other container engines, cntr also takes PIDs.
