Replacement for Docker Desktop on Windows? (lemmy.world)

submitted 1 year ago by [email protected] to c/[email protected]

Folks, I have a node.js script running on my Windows machine that uses the dockerode npm package to talk to docker on said box and starts and kills docker containers.

However, after the containers have been killed off, docker still holds on to the memory that it blocked for those containers and this means downstream processes fail due to lack of RAM.

To counter this, I have powershell scripts to start docker desktop and to kill docker desktop.

All of this is a horrid experience.

On my Mac, I just use Colima with Portainer and couldn't be happier.

I've explored some options to replace Docker Desktop and it seems Rancher Desktop is a drop-in replacement for Docker Desktop, including the docker remote API.

Is this true? Is Rancher Desktop that good of a drop-in replacement?
Does Rancher Desktop better manage RAM for containers that have been killed off? Or does it do the same thing as Docker Desktop and hold on to the RAM?

Are there other options which I'm not thinking of which might solve my problems? I've seen a few alternatives but haven't tried them yet - moby,
containerd,
podman

I don't actually need the Docker Desktop interface. So pure CLI docker would also just work. How are you all running pure docker on Windows boxes?

The integration of Docker for windows with wsl2 is an abomination that breaks just about every time I update either ddw or windows. Also the fact that it is tied to my user account ( both ddw and wsl2) means that it is not a great choice for persistent services. I still use it to provide monitoring agents for Prometheus and portainer, but otherwise everything runs on Linux vms on my homelab xenserver cluster.

It is possible to install docker without ddw. It’s documented for server versions of windows, but is basically only for running windows containers. The only use case for that is windows build agents as far as I can tell.

Docker can be installed standalone on wsl2 and would be more reliable.
