Cloud-Init not accepting nocloud datasource

[scahartner]

I am trying to boot a bare-metal system running ubuntu 20 and use cloud-init with the nocloud datasource (https://cloudinit.readthedocs.io/en/latest/topics/datasources/nocloud.html) to apply the initial configuration.

I was thinking about updating grub to apply the settings:


ds=nocloud-net;s=http://10.10.0.1:8000/

and then host the user-data and meta-data files via http.

However I am not sure were I need to specify the grub parameters.


root@ubuntu-base:/home/user# cloud-init status --long
status: done
time: Wed, 06 Jan 2021 09:53:14 +0000
detail:
DataSourceNone


The system was installed using PXE and autoinstall so cloud-init has already been installed and seems to be working. I am hoping that I just have to introduce a new datasource and then apply the configration via user-data.

Any pointers on how to pass these parameters to the system.

Tried updating /etc/default/grub with the following


GRUB_DEFAULT=0
#GRUB_TIMEOUT_STYLE=hidden
GRUB_TIMEOUT=30
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="serial=ds=nocloud-net;seedfrom=http://192.168.0.172/ubuntu/config/"
GRUB_CMDLINE_LINUX="serial=ds=nocloud-net;seedfrom=http://192.168.0.172/ubuntu/config/"


However this doesn't work. I don't see any request on the http server side and cloud-init still reports no data source.

Even using this did not work either:

GRUB_DEFAULT=0
#GRUB_TIMEOUT_STYLE=hidden
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="-smbios type=1,serial=ds=nocloud-net\;seedfrom=http://192.168.0.172/ubuntu/config/ ds=nocloud-net\;seedfrom=http://192.168.0.172/ubuntu/config/"
GRUB_CMDLINE_LINUX="-smbios type=1,serial=ds=nocloud-net\;seedfrom=http://192.168.0.172/ubuntu/config/ ds=nocloud-net\;seedfrom=http://192.168.0.172/ubuntu/config/"
