Feature Request: Ability to halt the container

[Svenum]

I want just halt the container for faster wake up times. Maybe with a setting in sablier.yaml?
This should save CPU + its fast up and running.

The underlying action for docker is the equivalent of docker start and docker stop.

By halting containers, do you mean using the docker pause command ?

https://docs.docker.com/engine/reference/commandline/pause/

Do you have more details on how you'd it manually ? This would be helpful understanding this process.

For now, this is not an available option, but can be added to.

Right I want to use docker pause and docker unpause instead of docker stop and docker start

[acouvreur]

Can you give me more details on the use case ? Out of curiosity.

Because the memory is not discarded and the process are frozen.

What's the use case that you need to unpause containers to boot very fast ?

In my mind are services like jellyfin or Nextcloud witch clients dont wait that long. After the timeout they force you to reenter the server name.

It appears that the command docker checkpoint should be taken into consideration

[Svenum]

I do not want to do a snapshot I want to stop the container without the need to start everything on need. I want to reduce CPU Usage and a fast startup. So I do not think that docker checkpoint is what we need here.

Some news on this?
