DevOps Megathread: what you need and how we can help!

Hello,
If you want to discuss the Pulumi Provider in detail, let discuss here: https://xcp-ng.org/forum/topic/10592/pulumi-xen-orchestra-news

@Jonathon this is really nice to have shared, as we are looking to migrate from the RKE cluster we've deployed on bare-metal Xen to XCP-ng VMs to setup an RKE2 cluster to migrate to.

Will review this and probably have a bunch of questions!

@andrewperry I myself migrated our rancher management cluster from the original rke to a new rke2 cluster using this plan not too long ago, so you should not have much trouble. Feel free to ask questions

i found time to play with cloud init, most of examples looks outdated or don't work dunno why.

hostname: {name} don't work, only hostname: {name}%. Also i don't find that macros at official doc.

with manage_etc_hosts: true it changed /etc/hosts 127.0.1.1 basename to 127.0.1.1 basename test%. Maybe package itself bug, maybe XO problem.

preserve_hostname: false looks not required, i don't see any difference.

even if not use any network config, it change netplan (don't need it with dhcp).

network:
  version: 2
  ethernets:
    enX0:
      dhcp4: true

to

network:
  version: 2
  ethernets:
    enX0:
      match:
        macaddress: "my_mac"
      dhcp4: true
      dhcp6: true
      set-name: "enX0"

to save default netplan, need to use something like

network:
  version: 1
  config:
      subnets:
      - type: dhcp4
      type: physical

can't make disk resize work, it looks like rocket science. And this is most important part for me.

resize_rootfs: true
growpart:
  mode: auto
  devices: ['/']
  ignore_growroot_disabled: false

I'm fine enough with manually tuned templates, 99% time don't need to change anything except name\disk. Other tasks require manual attention anyway or already covered with ansible. Would be nice to see tutorial for IQ<3.

Hello, thanks for the report. I will try to fix and improve things, but before I have a few questions.

What is the template you are using? Is it one from XOA Hub?
Where did you found the cloud-init config snippets?

For your information, the defaults cloud-init configs snippets come from here: https://github.com/vatesfr/xen-orchestra/blob/master/packages/xo-web/src/common/cloud-config.js#L78-L88

For growpart it depends of the template used. Last time I tested it was working with a Debian 12 template from the XOA Hub.
