Windows Script to Sync Cloudinit Network Configuration

[ericwang401]

This is a repost and wasn't made by me.

Might help someone here, this pulls the address, gateway, netmask from Proxmox's Cloudinit function in Windows command prompt
Cloudbase was giving me issues so I prefer to just make a bash script that does it for me automatically

This script may require a Cloudinit drive to be mounted on the VM where this script is being run on.

@echo off

setlocal

for /f "tokens=2" %%a in ('type "D:\OPENSTACK\CONTENT\0000" ^| findstr "\<address\>" ^| findstr /r "[0-9.]*"') do set ADDRESS=%%a
for /f "tokens=2" %%a in ('type "D:\OPENSTACK\CONTENT\0000" ^| findstr "\<gateway\>" ^| findstr /r "[0-9.]*"') do set GATEWAY=%%a
for /f "tokens=2" %%a in ('type "D:\OPENSTACK\CONTENT\0000" ^| findstr "\<netmask\>" ^| findstr /r "[0-9\.]*"') do set NETMASK=%%a

echo ADDRESS=%ADDRESS%
echo GATEWAY=%GATEWAY%
echo NETMASK=%NETMASK%

endlocal

I myself use this version of script which also have setting up DNS'es

@echo off

setlocal

for /f "tokens=2" %%a in ('type "D:\OPENSTACK\CONTENT\0000" ^| findstr "\<address\>" ^| findstr /r "[0-9.]*"') do set ADDRESS=%%a
for /f "tokens=2" %%a in ('type "D:\OPENSTACK\CONTENT\0000" ^| findstr "\<gateway\>" ^| findstr /r "[0-9.]*"') do set GATEWAY=%%a
for /f "tokens=2" %%a in ('type "D:\OPENSTACK\CONTENT\0000" ^| findstr "\<netmask\>" ^| findstr /r "[0-9\.]*"') do set NETMASK=%%a

netsh int ip set address name="Ethernet" source=static ^ address=%ADDRESS% mask=%NETMASK% gate=%GATEWAY%
netsh int ipv4 set dns name="Ethernet" static 8.8.8.8 primary validate=no
netsh int ipv4 add dns name="Ethernet" static 8.8.4.4 index=2
