From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

it's not always sunny with podman (lemmy.ml)

I am moving from docker to podman and selinux because I thought that podman is more secure and hence, the future. I thought the transition will be somewhat seamless. I even prepaired containers but once I migrated I still ran into issues.

minor issue: it's podman-compose instead of podman compose. The hyphen feels like a step back because we moved from docker-compose to docker compose. But thT's not a real issue.

podman does not autostart containers after boot. You have to manually start them, or write a start script. Or create a systemd unit for each of them.

Spinning up fresh services works most of the time but using old services that worked great with docker are a pain. I am wasting minutes after minutes because I struggle with permissions and other weird issues.

podman can't use lower number ports such that you have to map the ports outside of the machine and forward them properly.

Documentation and tutorials are "all" for docker. Github issues are "all" for docker. There isn't a lot of information floating around.

I'm still not done and I really wonder why I should move forward and not go back to docker. Painful experience so far. https://linuxhandbook.com/docker-vs-podman/ and following pages helped me a lot to get rid of my frustration with podman.

Podman is great, but a lot of confusion arise from the rapid development the last ~year and the fact that different distros have relatively old versions in their repos.

I recommend using the latest Fedora Server and defining your containers as quadlets. Also, on Fedora, yoi can install Cockpit (and cockpit-podman) and get a decent webgui to manage your host and container.

I should just write a blog post about this instead of typing this up on my phone in bed 😆
