Assigning secondary IP address using Cloud-Init

[Loredo]

Hi,

I would like to assign secondary IP addresses to a single network device using the cloud-init configuration.
I can read from the specification that this is possible to do. However, the Proxmox API and frontend does not allow to enter more than a single IP address. It would be great to allow multiple IP's using a comma separated list type. Shouldn't be too hard to loop through it and put this to the 50-cloud-init.yaml file in the correct format.

Sadly no public source code seems to be available so I can't provide a patch to you guys :-(
May I ask if you could put this into your backlog?

-----

Meanwhile, I was looking for a workaround by manually putting a file somewhere within the image. Ideally that would be a single command like

ip address add 192.168.6.2/32 dev eth0

but it seems I am unable to find the right point to put this. Tried to use a file in /etc/cloud/cloud.cfg.d/10_network_aliases.cfg like this:

runcmd:
 - [ ip address add 192.168.1.2/32 dev eth0 ]

without success. Any ideas besides waiting for the feature improvement in the Proxmox code?


Many thanks,
Julian

I take it that you've read our documentation on Cloud-Init Support? https://pve.proxmox.com/pve-docs/chapter-qm.html#qm_cloud_init

But ... public source code actually is available, see the git link in the footer of the forum pages. It's part of the qemu-server package. In general if you want to start contributing, the information about that can be found in our wiki: https://pve.proxmox.com/wiki/Developer_Documentation

Hope that helps,
Rhonda

I did read the documentation, it doesn't say anything about multiple IP address assignment. Trying to put multiple "ip=" settings into the ---ipconfigX parameter would result in an error message stating only a single "ip=" setting may be used.

Thanks for pointing me to the dev info, Google did not give me that page or other information about the repo. Will have a look but not sure if a patch could be developed being new to the code structure. If you can, I would still appreciate to have that as part of the official backlog.

Out of curiosity, do you remember what you googled with? Maybe we can try to improve on that grounds. And thanks for sending patches in already.
