Can you ping back on Monday so I don't forget?

Hi, is there any way to enable verbose logging for cloud-init during the boot process to see what sections have actually been executed (passed

if

statements) from files in

/system/oem

and

/usr/local/cloud-config

and in what order?

Hi, can we use elemental as standalone binary to create derivative iso ?

I have what might be a silly question. Is the luet package manager required to build a container OS? I'm guessing it is based on https://github.com/rancher-sandbox/cOS-toolkit/blob/c47e98f487f383d4dca2e884b84a9ee7376aacdb/examples/scratch/Dockerfile#L17

Thank you for that video. I am very interested in the c3os work briefly shown around minute 37. We (at Tripwire a HelpSystems brand) are currently using k3os+k3s and are seeking a path to migrate away from k3os.

What's the status of SLE Micro for Rancher?

Hello, there is a rebrand to elemental cli ?

And you move them to rancher repo ?! So it's no more a alpha project ?!

Has the dust settled yet? Seems like somewhere in the move to SLE Micro for Rancher rancheros-operator (soon to be renamed elemental-operator) broke.

Hi, I was just curiously trying to bootstrap a test cluster with elemental via iPXE. I have a single node that came up with v1.22.10+k3s1 and started to cluster-init but it's stuck waiting for kube-controller-manager to come up. However, k3s-server isn't listening on port 10252 like it expecst.

Hi Team - first and foremost, thanks for the awesome work so far! The approach of elemental (operator) is really amazing, kudos! 😃 I was able to install the 0.2.1 operator in my lab, but I wasn’t able to proceed with a proper MachineRegistration 😞 Do you have an update of the docs (elemental.cattle.io/v1beta1?) somewhen close on your roadmap?

how do you mount another disk? I'm setting up a disk for Longhorn via cloud-init commands and

/var/lib/longhorn

gets remounted as a bind mount to

/usr/local/.state/var-lib-longhorn.bind

new release of elemental-cli available: https://github.com/rancher/elemental-cli/releases/tag/v0.0.16

I’m experimenting with kairos on an RPI4 with a USB-to-M.2 adapter for booting from an SSD (no SD card), but I seem to running into a segfault in

elemental-cli

during the boot process (initial boot). After the boot process dumps out to the emergency console,

journalctl -u cos-setup-rootfs

reveals:

Copy code

systemd[1]: Starting cOS system early rootfs setup...
elemental[712]: time="2022-08-18T12:00:11Z" level=error msg="invalid arch: invalid arch"

(pardon: I hand-typed that from a camera photo)

it says invalid arch in there...what iso are you using?

I’ve ripped open the initrd (from an AMD64 machine… and wow I had to go deep to get it out), and checked the

elemental

binary:

Copy code

jalonso konin /tmp/initrd/early/usr/bin
$ file elemental 
elemental: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), statically linked, stripped

happy-island-57258

10/18/2022, 2:54 PM

I probably should have checked to see if

elemental

was willing to execute on the running RPi4 itself, but I did manage to get a go stacktrace, rather than a kernel-level rejection of the binary.

ripe-mechanic-63260

10/18/2022, 2:55 PM

Oh, it's an 32bit arm elemental in there?

happy-island-57258

10/18/2022, 2:55 PM

Yeah, I thought to check when you asked after the iso.

ripe-mechanic-63260

10/18/2022, 2:57 PM

Check how kairos builds the RPI image, maybe they are bundling the wrong image? Maybe the package they are using is broken so the issue is under elemental

ripe-mechanic-63260

10/18/2022, 2:58 PM

I know we release arm64 binaries and an arm64 luet package

happy-island-57258

10/18/2022, 2:59 PM

Is there a plausible explanation for why I’m seeing a go stacktrace? That implies the ELF started.

ripe-mechanic-63260

10/18/2022, 2:59 PM

Yeah that makes no sense, especially because the arch message and panic comes from inside the binary...

happy-island-57258

10/18/2022, 3:06 PM

TBH, I’d probably have quicker results interrogating

elemental-cli

build artifacts with

file

than I would teasing apart the kairos build process.

happy-island-57258

10/18/2022, 3:07 PM

(That’s a statement on my setup and familiarity with components.)

ripe-mechanic-63260

10/18/2022, 3:10 PM

Umm, I don't have an rpi to test that, I'll have a look tonigth at our elemental artifacts to see if they are correct

ripe-mechanic-63260

10/18/2022, 3:10 PM

The correct arch I mean

ripe-mechanic-63260

10/18/2022, 3:11 PM

Maybe rpi4 reports the arch differently to what we expect

happy-island-57258

10/18/2022, 3:17 PM

It’s worth saying that some kernel builds can be set up to run both 32-bit and 64-bit binaries, though some are not. I still wonder if the

elemental

binary was somehow put together from a mix… which should be wrong.
