Man, I feel bad for Docker, the company. Created the open source project that almost single-handely revolutionized deployments, development environments, and cloud computing, but sorta never managed to stick a product.

I think they are now doing better than ever. And they have been bought out already by Mirantis, unless I missed something.

Podman isn't really a competitor at this point, it's just the "docker at home" NIH project from redhat. It works fine, but docker isn't going anywhere really.

I tried to use podman desktop for a bit but I ran into some screwy compatibility issues. It just wasn't as smooth as docker. I really really want an alternative to docker desktop. I don't like the path they're going down. I don't like the AI crap in the UI. The licensing is crazy. It just doesn't feel right. So I've been lately using rancher by SuSE. Surprisingly, it's been all right. So far it just works. I'm using…

What sort of compatibility issues were you encountering? (disclaimer: I'm on the Podman Desktop team) If it was compose + docker compatibility issues, that's on the roadmap for improvement :). Compose support is flakey at times (it's essentially a wrapper around the open source binary https://github.com/docker/compose )

If you're open to questions, I'm switching my teams from Docker to Podman on macOS. I'm hitting blockers for multi-user setups i.e. each developer has a non-admin account on the machine, whereas brew runs in its own account with admin permissions.

I would love a way to have Podman installable in userspace meaning in a non-admin account, or installable without brew, or with a dependency list such as QEMU or whatever else needs to be installed by an admin ahead of time, or with a sudousers config list, etc.

I know this is an atypical setup. Any advice from anyone here is much appreciated about multi-user non-admin macOS container setup for Podman or Docker or equivalent.

OrbStack is a very compelling alternative on macOS. The GUI launches instantly due to being a Swift app and not Electron. Container filesystems are visible in Finder. You can spin up full-blown VMs with it (only Linux ones though). Storage is managed dynamically, so you don't have to reserve or resize the virtual disk. Free for personal use, with zero nags or upsells.

Does anyone know if the company is still active. Haven't seen any updates for a while now. I like the product a lot, but products like this need security updates at the very least.

I'm still confused by why anyone wants to use either Docker or Podman desktops. The the docker/Podman CLIs seem like a much better way to interact with containers/images. Maybe it's just my usecase.

I personally use Docker Desktop because it was the easiest way to install Docker on my Mac. I launch Docker Desktop, close the window but keep the app running in the background, then use the docker tool on the command line :)

I put off podman for a while because of claims of compatibility issues, which is unfortunate because I've had an excellent experience since switching over. Can you point as specific issues you've had (not doubting, just curious)? I also have heard a lot of recommendations for OrbStack, but I haven't had problems with speed either. And I could never stomach using a proprietary system for such a core part of my workflo…

I've had a ton of issues trying to use Podman instead of Docker on Fedora. SELinux keeps blocking Podman from doing stuff it needs to, while Docker just works.

I've also experienced Podman "getting stuck" sometimes: it's just running a build, but ctrl+c somehow doesn't stop the build system and instead freezes Podman. Doesn't really happen with Docker.

The best alternative to Docker Desktop on macOS is to abandon the GUI entirely use colima to create the linux VM. brew install colima docker docker-buildx docker-completion docker-compose export DOCKER_HOST="$HOME/.colima/docker.sock" >> ~/.zshrc source ~/.zshrc colima start --cpus 8 --vz-rosetta --ssh-agent --mount $HOME:w then add this line to your $HOME/.docker/config.json "cliPluginsExtraDirs": ["/opt/homebrew/li…

Thank you!!! Been struggling with time skew on Podman desktop for around a year now with no fix in sight. At least in the initial test since I saw your comment a few hours ago, this is working great!

Earlier quoted context omitted.

I imagine that OrbStack has containerd buried inside somewhere and could support ctr and (awkwardly) nerdctl, but if so it’s pretty well hidden.

I build containers for multiple platforms using orbstack, and that requires the containerd backend. So yes, it's in there somewhere.

Huh. Are you actually talking to containerd directly or are you just doing something via the docker frontend that requires containerd to function?

Tried Podman about a month ago; UI was kinda meh, 'compose' was beyond unusable... then tried Colima (+ lazydocker, a lightweight, beautiful TUI providing the little overview I need) and haven't looked back for a single second.
