How can I change /etc/network/interfaces with ip commands (persistent)?

[jsterr]

I would like to modify the file without using the web-ui and without sed commands, is there a way to do this with ip commands?
ip add etc. seems to be not persistent on reboot.

Hi,

is there a way to do this with ip commands?

to put it simply: no.

ip (from the iproute2) does not have anything to do with the persistent network configuration, done using ifupdown2. ip can only manipulate the running system.
If you really want to use these commands for some reason, you could create a cronjob/service that runs on boot and executes these commands directly or via a separate script file. But I would not recommend that.

Edit: Just to mention it for the sake of it: You can also create your own, separate file under /etc/network/interfaces.d/ and source it from /etc/network/interfaces, which e.g. the SDN integration does too. That way you would have control over the exact contents of the whole file.

IOW, what are you trying to achieve exactly simply by not using /etc/network/interfaces?

What about pvesh and PVE API to change the config via CLI/script?

We want to automate network creation via scripting so we dont need to use ui.
So like create config for corosync, webui, create a vmbr0, some bonds etc.
So no manual file editing via cli

everything you see on the GUI is done over the API

Thanks! How can I set the IP-Address, theres no "address" field.

root@pve:~# pvesh set /nodes/pve/network/eno1 --address 10.10.10.1
400 Parameter verification failed.
netmask: missing property - 'address' requires this property
type: property is missing and it is not optional

My first steps with the pve api, cool

EDIT: Got it:

root@pve:~# pvesh set /nodes/pve/network/vmbr1 --type bridge --address 10.10.10.10 --netmask 255.255.255.0
