<p>One of the most interesting features of podman is that it is daemonless. There isn&rsquo;t a process running on your system managing your containers. In contrast, the docker client is reliant upon the docker daemon (often running as root) to be able to build and run containers.</p> <p>One of the most interesting features of podman is that it is daemonless.

<p>Podman is rootless by default. It is now possible to <a href=https://docs.docker.com/engine/security/rootless/>run the docker daemon rootless</a> as well, but it&rsquo;s still not the default behaviour.</p> <p>Podman is rootless by default.

<p>Installing podman on macOS was not seamless, but it was manageable well within 30 minutes of time. I would recommend podman to anyone who is unhappy with experiencing forced docker updates, and who wants to use a more modern technology for managing containers.</p> <p>Installing podman on macOS was not seamless, but it was manageable well within 30 minutes of time.

<p>One thing to note is that there isn&rsquo;t a graphical user interface for podman, but there is an <a href=https://github.com/containers/podman/issues/11494>open issue</a> considering one.
