cloud-init / nocloud plans #67

Open clebergnu opened 3 years ago

clebergnu commented 3 years ago

Are there any plans to bump cirros' support for cloud-init / nocloud beyond its current state? As far as I can tell, it currently supports a similar meta-data, but an executable only user-data.

I understand that recreating cloud-init is not an option, but I just wanted to check if there are any plans in this area.

clebergnu commented 3 years ago

@smoser ping, any input here would be appreciated. Thanks!

What would you like to see ? I can absolutely see a desire for networking information. We don't currently have any way to feed network info to cirros.

Basic network configuration would be a great start.

My initial use case has to do with QEMU functional tests, where booting a guest defaults to using Fedora (but can easily use other distros). With emulation (that is, without KVM) this can be quite slow.

There have been discussions on building/using custom lightweight distros for this purpose, but I believe CirrOS is well suited to that. If configuring the network stack was consistent across distros such as Fedora, CentOS, Debian, Ubuntu and CirrOS, CirrOS would be the definitive choice for many scenarios.

Then, the linked PR from the Kubevirt project apparently has the exact same perspective.

Let me know if this makes sense to you.

osfrickler commented 2 years ago

I think it would be great to support network configuration. I have no idea how to approach that, though. Ideas or patches welcome.

I run cirros in qemu-kvm environment for testing openvswich bridge vlan/vlxan or other functions.

virt-install \
  --name cirros01 \
  --vcpus 1 \
  --memory 256 \
  --disk path=/var/lib/libvirt/images/cirros01/cirros-0.6.2-x86_64-disk.img \
  --os-variant cirros0.5.2 \
  --import \
  --autostart \
  --noautoconsole

but it need much time to start, because it need connect checking http://169.254.169.254/2009-04-04/instance-id 20 times.

In this serverfault link have a way use --boot kernel ds=nocloud to resovle the problems.

But this requires a lot of extra work：

wget https://download.cirros-cloud.net/0.6.2/cirros-0.6.2-x86_64-uec.tar.gz

untar

tar -zxvf cirros-0.6.2-x86_64-uec.tar.gz -C /var/lib/libvirt/images/cirros02/

use --boot kernel to rerun vm, this will solve the problem and start immediately

export IMAGES_BASE=/var/lib/libvirt/images
virt-install \
  --name cirros02 \
  --vcpus 1 \
  --memory 256 \
  --boot kernel=$IMAGES_BASE/cirros02/cirros-0.6.2-x86_64-vmlinuz,initrd=$IMAGES_BASE/cirros02/cirros-0.6.2-x86_64-initrd,kernel_args="console=/dev/ttyS0 ds=nocloud" \
  --disk path=/var/lib/libvirt/images/cirros02/cirros-0.6.2-x86_64-disk.img \
  --os-variant cirros0.5.2 \
  --import \
  --autostart \
  --noautoconsole \
  --network network:ovs

And i don't know how to change cirros image quickly, i use virt-customize command it failed

root@node1:~# virt-customize -a cirros-0.6.2-x86_64-disk.img --run-command 'echo DATASOURCE_LIST="nocloud" > /etc/cirros-init/config'
[   0.0] Examining the guest ...
virt-customize: error: no operating systems were found in the guest image

If reporting bugs, run virt-customize with debugging enabled and include 
the complete output:

  virt-customize -v -x [...]
root@node1:~#

Then I searched for other tina images, such as the popular Alpinelinux, which provided the nocloud image. However, the user of this image does not have a password by default, making it more difficult to test.

This has trapped me in a dead cycle, forcing me to return to circos.

So the current question is whether cirros can solve this problem through the following methods

willzhang commented 8 months ago

I find the way here：proxmox-cirros

}

#!/bin/sh
echo DATASOURCE_LIST="nocloud" > /etc/cirros-init/config

install vm
