Suspension of containers

[thomas-mc-work]

Currently there are two ways to interrupt a running container:

• stop: Terminates the process
• pause: Pauses the execution by keeping everything in the RAM

I'd like to have a suspend command which triggers a pause first and then writes the RAM on the hard disk. This allows meto hibernate an instance and carry on later. A subsequent command resume read the persisted data back into the RAM and triggers an unpause command.

WDYT?

There's (experimental) support for CRIU (https://criu.org/) through the docker checkpoint commands, but it requires the daemon to be running with experimental features enabled; https://docs.docker.com/reference/cli/docker/checkpoint
