Add links to Linode Guide and Ycombinator discussion of "Podman vs Docker"
<br />
== Podman vs Docker ==
Podman runs in a fork-exec model, not a client-server model avoiding the overhead of the [[Docker]] daemon that runs continuously and consumes significant resources. Furthermore Podman runs on the host as the local user, not root so it is fundamentally more secure. Speaking of security, since Podman comes from RedHat, it's no surprise that it runs just fine with SELinux set to "enforce" mode. While Docker offers AppArmor as a security layer, it's too lax by default, you have to learn the syntax, and write your own policies, AND it doesn't work with rootless Docker, nor does it offer isolation between containers <ref>https://www.redhat.com/sysadmin/apparmor-selinux-isolation</ref>.
<br />
For a good deep dive on the comparison, see the "guide" article on Linode.com https://www.linode.com/docs/guides/podman-vs-docker/ and the discussion of it on Ycombinator https://news.ycombinator.com/item?id=34719137<br /> == Pod security ==
Using [https://github.com/containers/udica Udica], you can generate SELinux policies for your containers.
<br />
== Podman Desktop ==
Like Docker Desktop, there is a graphical application called '''Podman Desktop''' (https://podman-desktop.io/) that you can use to build, run, and manage your containers, pods, and other objects. It even allows you to work with Kubernetes from your local environment.
