How does podman work with giving native access to resources? Like on a raspberry pi with docker you need to tell docker it has the ability to access /sys for the GPIO pins and for I2C etc. does podman have this too?

#143Docker is not dead, despite the attempts of Red Hat (and Google) to kill it.
The market changed and Docker changed to stay relevant. Just that.

#144Earlier quoted context omitted.
By default container images are not signed (there is notary, but it's not commonly used - maybe notary V2 will change that - and I think the signature changes depending on the registry it's hosted on anyway?) which make it inconvenient to mirror. Now, why are we still producing new package formats without mandatory signatures (containers, npm, cargo, etc) is not really clear to me. I guess everyone must think "those…
The layers have checksums so couldn't you store the metadata centrally and mirror the checksummed blobs?
What is rate limited on docker hub is fetching the image manifest, rather than the blobs, so that wouldn't work I think.

Typing this on a Asus 1215B that was sold with a Linux distribution and has already had a couple of LTS distributions since 2009. Even though it was sold as Linux supported device, it had its own series of issues, with wlan driver being broken when Canonical decided to replace it for a less capable one taking 6 months to reach feature parity, nowadays GL is stuck at 3.3, although fxgl used to be able to do 4.1. And t…
Makes me think of what other laptops (or even just PC hardware in general) have some of the best support on *nix. Personally, in my experience most hardware has been passably okay, at least when compared with trying to run FreeBSD, though some required tweaking (such as touchpads). I think Lenovo ThinkPad laptops have some of the best reputation in that regard, though the newer models can definitely be a bit on the p…
With ThinkPads, just buy a few generations behind refurbished, preferably from a nonprofit recycler. They've always been great for Linux. The T series gives you more upgrade options, but the X models run longer on a charge and are small and light . I'm on my second now, having "upgraded" from a T430 to an X250. But I miss the larger screen and so will probably get a T470 or T480 soon.
Running boring plain vanilla Ubuntu LTS with the ("curse you, FreeDesktop.org!") Gnome Shell and a few extensions that probably drive the minimalists on the Gnome Project bonkers (also running a lot of web apps like Gmail and Keep as PWAs). Or at least I hope they do. Mostly program, don't game: I leave that to my kids, both game developers. As a literal greybeard I don't care much if The Year of the Linux Desktop ever comes, because I've been living The Life of the Linux Desktop for over two decades.
Still using docker for workloads at home, but if I was still managing massive numbers of containers at work I'd probably be running podman for anything that didn't justify the cost and complexity of k8s.

#146People complaint about framework or library churn in the JS world, but other ecosystems have the same issue. For people who aren't following this ecosystem closely, I just want something that works and gets out of the way with a minimal learning curve.
Navigating fragmented ecosystems sure is a pain... I get that different tools serve different needs, but having to learn a bunch of different things just to figure out which one to use gets really exhausting. Especially when you have to do it for tools at every layer of your stack.

#147Have you ever used podman-compose? It's amount of bugs and missing features is bigger than actual features count.
Podman 4.x is pretty great with docker-compose due to its API compat with Docker. Give it a shot.
This sort of makes the whole premise confusing to me. The way to use the alternative to the "dead" product is to use the dead product.
This isn't a critique of your comment. Just, that I don't understand what's going on here. Maybe this whole issue is a non-Linux kind of thing?
Test stuff out with wither docker compose, or minikube, and otherwise deploy to k8s has worked great for me.

JS is a punching bag because it’s a moving target that most everyone has to deal with at some point and pre-ES6 JS had quite a few warts. It’s a fine language now, especially with TypeScript helping to push things in the right direction.
I left .NET land for this very reason. JS pales in comparison to .NET framework fatigue

So you can use kubectl but it talks to podman and not to the api of a k8s cluster? Or does it have its own cli?
There's apparently a 'podman play kube' command that can take some k8s yaml like pod descriptions and instantiate them directly: https://docs.podman.io/en/latest/markdown/podman-play-kube.1... I hadn't heard of this until now but it sounds pretty nifty!
Exactly. Here's a pod.yaml I use for testing a service at work:

It can probably be even more concise, but I stopped stripping stuff out here.

#150BTW there's no alternative to docker compose in podman, I've tried running my docker compose file with podman compose and it just failed outright. Currently I'm going to stick with Docker because of this alone.
