CentOS is dead.
I only learned about this as a side note from one of Brad's posts in the recent past. This is a huge blow to me given I'm RHEL/CentOS trained and it has been my go-to distro for more than ten years now. Never mind the fact that it is a clear money grab that isn't going to get as much money as RH hopes.

What are you guys moving too? At this point I feel like I'm forced into Ubuntu LTS. I can't really go with CentOS Stream since it isn't really "production". My old boss loved FreeBSD, but I can't stand it. Too many gotcha's and processes to do simple things. I'd have to look up guides for every single thing I do on those servers.

Other than Ubuntu LTS?

I think their #3 — Cloud Linux— has been renamed to AlmaLinux. If not, I’d add that to the list, too. Also, if you have 16 or fewer production servers, you can just use RedHat for free. They changed their licensing when they canceled CentOS.

When I was a kid, people who did wrong were punished, restricted, and forbidden. Now, when someone does wrong, all of the rest of us are punished, restricted, and forbidden... and the one who did the wrong is counselled and "understood" and fed ice cream.

Yeah I could limit to fewer that 16 that run RedHat, but I'd rather not have some limit I forgot about when I needed to spin up a new server.

I've seen those articles looking around and they all seem to want to point to a "CentOS/RHEL" like linux distro. I'm not bent on sticking with them at this point. I guess this is why I end up leaning to Ubuntu. Plus, it is easier to train subodinates how to do basic things since it is so widely supported. Plus, for work, we are cheap and don't want to pay for things.

I've been on Ubuntu Server for many years and it seems… fine.

Not flawless, though.

One of the things it's really dumb about (maybe they fixed it a while ago?) is that it defaults to a relatively small boot partition, and if you don't reboot it for a while, it'll fetch multiple updates to the kernel until there is too little space on the boot partition to either 1) install any of the updates, or 2) reboot into a new version. If you're not careful, you render it unbootable (by the sheer act of… not having rebooted it).

The thing that screwed me over even harder is when a `sudo do-release-upgrade` decided to remove support for older OpenSSH ciphers, and… locked me out. Completely. Without warning. Wow, thanks folks.

Thank you for the heads up on that one! I don't reboot that often for these servers but I'll have to pay attention at least. I normally run Zabbix monitoring which specifically monitors free space and all so I should be good there and at least get some notification of some sort from it.

Yep. I also severely lament the loss of CentOS. I "grew up" learning on Red Hat Linux (before Enterprise) in the early aughts, and continued with RHEL and CentOS in professional and personal settings.

The Ars post Dave linked has an excellent description of how CentOS Stream is built, and its list of RHEL alternatives is pretty comprehensive. Unfortunately, I wouldn't really recommend any of them for reasons varying from trust (Oracle? LOL please) to age/maturity and general adoption rate.

I don't have a lot of long-running Linux machines today, but I'm probably going to slowly transition anything I maintain to some flavor of Debian, maybe Ubuntu if I can cleanly rip out all its telemetry. AppleNova's server here is running a relatively old version of CentOS that has gone through many changes over the years, and I've been meaning to upgrade for a while anyway, but at this point, I'm far more likely to trash and rebuild the whole damn thing clean on Debian stable.

On the professional side, pretty much all my work in recent years has been in Docker containers. Some have been built on UBI (basically "bare-bones RHEL"), alpine, fedora, or any other distro I don't know or care about since it's part of another base image. RHEL or CentOS rarely enter the equation any more.

I'm starting to delve into Docker now so what do you run the for the Docker Server? I'm toying with Photon right now since mine is primarily in a vCenter environment and it works well with it... shocking I know.

In case you're not familiar yet with Kubernetes but are interested in Docker images/containers, allow me to blow your mind.

https://kubernetes.io/docs/tutorials/kubernetes-basics/
https://kubernetes.io/docs/concepts/...is-kubernetes/
https://kubernetes.io/docs/concepts/...ew/components/

Basically, k8s (the common abbreviation for Kubernetes) is this whole open-source orchestration framework/platform/tool for deploying and running containers in a server capacity. There's a lot to learn here, but it's a rabbit hole that I suspect you would enjoy digging through.

Also, I wouldn't be surprised if VMware/vCenter has some kind of support for k8s. It's the go-to technology in this space nowadays, and all the major hypervisors, cloud providers, etc. have some flavor of support or integration. Red Hat has a product called OpenShift that's basically k8s with extra features, but I would encourage starting with "plain" Kubernetes before looking into OpenShift.

I'm glad you mention this! My boss asked me to get familiar with AKS, or Azure Kubernetes Service!

I'll start digging now.

I know recent versions of VMware have some Docker integration, but not k8s, I think.

I'll have to check. Production we are still running 6.7 so I'm guessing they don't support it there. I'll dig into that on company time though Monday.
