Hi all!
I’ve been using RancherOS for years as the minimal OS to host all of my containers and it’s been working great. Until today.
I updated Redis to its latest version, and got some errors. After some investigation I found that in needs Docker 20 or higher to run. RancherOS has been abandoned, and the latest version you can install is 19.
Do you fine folks know something similar to RancherOS? Thanks!
I use debian as my OS for docker host, then install docker from them as you get the most up to date version
This is my plan B in case I can’t find a lightweight distro to replace RancherOS. Thanks!
Would Alpine be an option?
I’d suggest Alpine too. Works great for me so far.
I’ve been playing around with MicroOS, which is based off of OpenSUSE and is supposed to be the successor to RancherOS
It runs entirely in RAM, administration is super simple, no ssh, easy to update/and upgrade, immutable, minimal distro designed specifically for secure container usage.
This looks super interesting. Thanks! One question though; can I still use it if I don’t want to use Kubernetes? I just want to deploy a few containers here and there. I was thinking about moving everything to Kubernetes, but it seems a bit overkill for the 10 containers I have running.
I that case, check out Fedora CoreOS.
It is a fork of CoreOS, from when they got bought by RedHat and it was abandoned (or rather morphed into being fedora based).
It is has been fairly stable for me over the past two+ years, with one systemd-resolver snarfu. The auto update being baked in from the get go is nice.
Only thing to be aware of is that Kinvolk who are the maintainers have been bought by Microsoft, though so far it has not affected anything. Also if you don’t like systemd then it is not for you, as that is more or less all the distribution is.
They are running docker 20.10.23 on the stable branch atm. https://www.flatcar.org/releases
Looks good! I’ll give it a try. Thanks!
If you want a gui to manage your containers, I use portainer (with debian as OS).
I use it too! I really like it :)
