%post configuration in Kickstart of network isnt being retained
I am using a kickstart that assigns dhcp to the network (network --bootproto=dhcp --device=ens192 --noipv6)but in the %post portion of my kickstart I am running a script to set a static IP address. After rebooting the server to complete installation the NetworkManager is defaulting back to DHCP instead of the static information i had set previously. Is there something I am missing in the %post or is there something else I should be doing to get the static ip information to remain in networkmanager? Below is my post section and I changed the IPs. If i throw everything in %post into a .sh file it runs flawlessly in my live environment.
%post
!/bin/bash
Get the current IP address of ens192 assigned by DHCP
IP_ADDR=$(ip addr show dev ens192 | grep "inet " | grep -v "inet6"| awk '{print $2}' | cut -d/ -f1)
Extract the first three octets to detect the subnet (e.g., 192.168.1, 10.0.0)
SUBNET=$(echo $IP_ADDR | cut -d. -f1,2,3)
Define static IP, gateway, and DNS settings based on subnet detection
case $SUBNET in
"")
STATIC_IP="10.0.2.83"
GATEWAY="10.0.2.1"
DNS="10.0.2.81"
;;
*)
# Default IP settings if the subnet doesn't match any predefined options
STATIC_IP="10.0.1.83"
GATEWAY="10.0.1.1"
DNS="10.0.1.81"
;;
esac
Configure the static IP settings using nmcli (NetworkManager CLI)
nmcli con mod ens192 ipv4.addresses $STATIC_IP/24
nmcli con mod ens192 ipv4.gateway $GATEWAY
nmcli con mod ens192 ipv4.dns "$DNS"
nmcli con mod ens192 ipv4.method manual
Bring the network connection up to apply changes
nmcli device reapply ens192
nmcli con down ens192
nmcli con up ens192
