Podman Desktop: A Free OSS Alternative to Docker Desktop

Re: Podman Desktop: A Free OSS Alternative to Docker Desktop
#62Recently I started using colima[0], a drop in replacement for Docker Desktop on Mac, and have seen an increase in performance and battery life. You can use all the normal docker and docker compose commands. It does not have a GUI but you can use the Docker extension on VS Code to have an overview of running containers.

Best part: it's QEMU so you can choose your CPU architecture and run x86_64 containers on ARM Macs
That works via qemu userspace emulation inside of VM so docker desktop has it too (might need to install qemu binfmt_misc hooks package)

Please help me understanding: Why is `brew install docker` not sufficient, why do you also need Colima or Docker Desktop? Is it so that there is a docker _daemon_ installed which `docker` doesn't ship with?

I suppose Docker Compose won‘t work with those alternatives?
For Rancher Desktop, Docker Compose works with Rancher Desktop when you choose dockerd (moby). If you choose to use straight containerd (with nerdctl as a CLI) than compose isn't going to work.
If you choose to use straight containerd then you can use nerdctl compose too.

> For personal use I found it great and lighter than Docker Desktop. I don't know what Docker Desktop is doing but on a top end i9 with 128gb of ram it still takes 60 seconds to start and the UI takes forever to do anything it makes Teams look responsive
I user Rancher Desktop on an i9 with 32gb of RAM. Starts in less than a minute. I also have Teams and slack. Sometimes I have over 200 browser tabs open (yes, I have a problem). The UI is responsive pretty quickly. A lot of delays has to do with starting VMs. You need this for Linux on Mac/Windows. Disclaimer: I started Rancher Desktop. I might be biased.
raw "wsl --shutdown" followed by "wsl" takes maybe a second tops

OSX dose not support running docker containers (or vis versa depending on your point of view). Instead you need a VM running Linux. Docker Desktop / Colima runs this VM for you.

Are you on Windows? I believe it is using Hyper-V and running containers in a VM. The loading time is probably how long it takes to start the VM.
"Docker Desktop" uses a VM for container execution on all supported OSes - Windows, macOS and Linux - default installs are not running "docker" natively at your local CLI if you are using "Docker Desktop" to run docker, even on Linux. > https://www.docker.com/blog/the-magic-behind-the-scenes-of-d... > https://docs.docker.com/desktop/install/linux-install/ > https://docs.docker.com/desktop/faqs/linuxfaqs/#what-is-the-…
On windows, docker desktop can use Hyper-V, but it also supports WSL2 as a backend.

Also known as a VM, but maybe you get better warm up times. My main complaints are with the "docker desktop" app experience - not so much "docker" itself VM or otherwise. It adds so little to docker for the license cost too, at least so far.

You can simply install docker in a VM/WSL2 natively yourself and avoid docker desktop/licensing altogether. "Docker Desktop" is/was really a tool to simplify getting a Linux Kernel (the critical dependency for cross-platform container dev) on non-Linux platforms IMO, which seems wild to pay for to me in its current state and when Windows has a great built in VM via WSL2 anyway. That it even exists on Linux now (recent addition) is kinda amusing - on MacOS and Windows there is at least some argument to be made it simplifies getting the kernel...

I assume `brew install docker` just installs the docker CLI/etc, which can run on non-Linux OSes. However the docker daemon can only run on Linux, so something needs to setup a VM for it.
