03/31/2023, 12:34 AMI have no idea, but as long as it supports nested virtualization I don't see why not
b
broad-train-31975
03/31/2023, 12:34 AMI think so too. I’ll let you know

03/31/2023, 1:09 AM@fast-garage-66093 I can’t find the instructions on installing Rancher Desktop headless on Linux - which is going to be a Jenkins worker - I remember asking this already, but Slack does not seem to have this message anymore. I think it was ether installation flag… there’s no command line flags for rancher-desktop 😞

03/31/2023, 3:57 AMI don't know if this is sufficient, but you need some kind of display to run Rancher Desktop
b
broad-train-31975
03/31/2023, 5:45 AMWell, the definition of headless means no display. Perhaps we can come up with some way of setting initial configuration and then ignore the display?
Another question I had, why not run directly on Linux? Surely you can have a complete control of the VM, for a first and the main reason.

fast-garage-66093
03/31/2023, 5:51 AMPlease read the link I sent you; it should provide you with a virtual display for a headless setup:
First, install Xvfb. It's a virtual framebuffer, implementing the X11 display server protocol - it performs all graphical operations in memory without showing any screen output, which is exactly what we need.
fast-garage-66093
03/31/2023, 5:53 AMBut yeah, for a headless setup you could just run Lima directly without the Rancher Desktop around it. Or use colima.
b
broad-train-31975
03/31/2023, 5:57 AMI did read the link, but after I replied :)
Naturally I'm not the first to have the problem, and solution exists
broad-train-31975
03/31/2023, 5:59 AMIf I run Lima directly, will it give me everything RD has, like seamless integrated docker registry?
broad-train-31975
03/31/2023, 6:00 AMI want to save time an effort by not building my own solution. Not enough resources for that :(
f
fast-garage-66093
03/31/2023, 6:00 AMNo, Lima is more low-level, it allows you to run any kind of Linux VM on top of qemu, with shared volumes and port forwarding.
fast-garage-66093
03/31/2023, 6:01 AMcolima is a wrapper around Lima that provides preconfigured docker/kubernetes configurations and is probably better suited for headless environments.
fast-garage-66093
03/31/2023, 6:02 AMBut if you use Rancher Desktop on your local machine, then Xvfb should allow you to use the same config on CI.
b
broad-train-31975
03/31/2023, 6:02 AMSo I'll be better of running RD, first time providing a real display and, after initial configuration, a fake one
f
fast-garage-66093
03/31/2023, 6:03 AMYou don't need a real display, you can control everything via
rdctl startb
broad-train-31975
03/31/2023, 6:03 AMCan I always use a fake display and configure everything... You've just answered my question :)
broad-train-31975
03/31/2023, 6:05 AMGreat, thanks! I'll try that tomorrow - 23:06 here:)

04/03/2023, 10:28 PMHi @fast-garage-66093,
Some feedback - managed to run RD on Linux with nested virtualization. The Linux us Ubuntu 20.04 server, headless, i.e. no UI.
Ran into this error:
broad-train-31975
04/03/2023, 10:29 PMCan’t figure out which polkit agent to install, any ideas?
