I really tried to use Podman, but I kept running into issues trying to get a rootless deployment on RHEL that used a protected port (53) and it gave me so much trouble that I uninstalled Podman and installed Docker. Maybe I can try again, but it was frustrating enough to turn me away for a while.

Running into edge issues and always trying to figure out if it was my container, Podman, or SELinux is making me very close to installing regular docker.

The latest version of podman is always available at https://copr.fedorainfracloud.org/coprs/rhcontainerbot/podma... sudo dnf copr enable rhcontainerbot/podman-next -y sudo dnf install podman However the versions provided by the distro have gone through more tests. We are still improving this part as ideally you should be able to pick a version

Is it possible to run newer versions of podman and/or buildah as a container?

Yes. Podman in podman works, and this is how I sometimes tested on coreos without installing a new package. These days I mostly use a VM instead. Personal preference

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.

Starting a WHPX-accelerated VM with QEMU on Windows takes less than 15 seconds with a minimal init. Is Hyper-V really that much slower?

Don't think so. Starting WSL2 VM takes few seconds.

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…

You can use wsl-gvproxy(*), which uses our CRC usermode network stack to allow use with VPN. We are working on making this an option for podman machine. Alternatively, or to test, you can use CRC from our crc-org project and run the podman preset. This uses a dedicated VM using native hypervisors and the gvproxy setup. I am the teamlead of CRC and work on the Windows enablement of podman machine, with the podman desk…

Unfortunately I'm on MacOS and not Windows. But I'll pass this info to my Windows-using colleagues, thanks!

Recently 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.

Looking to convert, but I still can't understand how this is more performant. Docker Desktop has lots of engineering going into performance crossing the host/VM barrier. IIRC lima just pipes over SSH. How could that be faster?

Docker is an electron app which might explain some of the performance and battery differences. The containers don't run in electron but that extra copy of chrome is always running in the background.

This is considered good?
