yes; actually it's pretty cool because it shows you docker containers running on your system too and lets you manage those if you have any.

That's what Docker Desktop does and this is an alternative to Docker Desktop... Are you saying Docker Desktop on Windows doesn't have those features?

I believe they're saying is that podman can be run concurrently. They're just elaborating.

Gotcha, I thought I may have misunderstood. The wording made it sound "also, it's pretty cool because Podman (as opposed to DD) can do x, y, z" which didn't make sense to me. I was thinking "obviously Podman can do that if it's meant as an alternative to DD"

There's also Rancher Desktop in the same space, which includes k3s as a local K8s solution. For personal use I found it great and lighter than Docker Desktop. At work, unfortunately all options but Docker Desktop have issues with either 1) Our Cisco AnyConnect VPN, or 2) Our authenticated http proxy. Couldn't find anything else providing a container runtime + a local k8s on MacOS that works in this environment. So we…

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

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.

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.

Am I just a dum dum for not getting this to drop-in replace Docker Desktop for my relatively simple projects? Has anyone else experienced the problematic practicalities of switching, or should I just spend a bit more time with it?

For me the main reason to use Podman over Docker is rootless containers. Another one is also that Docker is really not pleasant to install on Linux.

> Another one is also that Docker is really not pleasant to install on Linux.

I'm curious on which Linux did you encounter issues while installing Docker? I cannot comment on the (to me somewhat pointless) Docker Desktop GUI installation on Linux, but I can confidently report that installing and using docker engine on Ubuntu, at least, is quite trivial and clearly documented[0] on the website.

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.

Just want to make sure: what they meant was Podman Desktop will show you both podman-based containers AND DD based containers.

The problem with podman at the moment (IMO) is version drift. RHEL/Fedora and friends get the latest and greatest (4), Debian/Ubuntu are stuck on 3.x. This isn't a problem with Docker, which has tight control over what is deployed. This means how you use Podman directly or indirectly via tools and plugins may change.
