> One of Podman’s greatest advantages is its complete CLI compatibility with Docker. In fact, when building Podman, Docker users can adapt without any significant changes. For example, you can use the alias command to create a docker alias for Podman: `alias docker=podman`

Wow that's a great adoption hack; just alias another program as another

I like the daemonless architecture a lot, but until there's a quick and painless way to install it on OSX and Windows developer machines, you're going to see very limited uptake.

Any docker Podman corner cases that people have run into? I like the idea of rootless containers but I can do that ether easily by adding one line to my dockerfile or adding a user flag when I run a docker container. What other advantages am I getting?

I really struggled with podman, a bunch of containers (I cant remember which ones) didn't work, and build tools choked as well.

At work we dont get root access so I thought it would be perfect but sysadmins couldn't figure out how to configure either so was bust there too.

This isn't about root inside the container but rather it doesn't need root on the host system.

I find it somewhat surprising that we haven't seen more adoption of the redhat docker (lowercase d) replacements after Docker (uppercase d) started pushing some of their monetization efforts.

The conclusion that I have to reach is that there are more docker users on Macbooks than I realized.

I was just thinking the same thing, and was going to ask if there was anything like Docker Desktop, something to make it simple to use on Windows/MacOS!
