Add network on interface and setup network file via dhcp

I think you need to create a dynamic date variable instead of using a fixed one like "20240106_11%3A57" in the url of https://images.linuxcontainers.org/images/openwrt/$VER/amd64/default/

This can easily done on runtime with an additional variable:
BUILDDATE=$(date -d "yesterday" '+%Y%m%d')
(... why yesterday? - to guarantee a working download even if todays version is not yet build)

Change the wget part to:
wget "https://images.linuxcontainers.org/images/openwrt/"$VER"/amd64/default/"$BUILDDATE"_11%3A57/rootfs.tar.xz" -O /var/lib/vz/template/cache/OpenWrt-$VER.tar.xz

Hey, thx for your suggestion, I've just updated the script above :)

Hello!
With yesterday's date, it doesn't always work.
I tried to install using the script and received an error, then I discovered that there was simply no release for yesterday.
You also have a missing letter in the word "network" in line 21

Thanks for the advice qtronixx!

I've updated the script to scarpe the last one in the list right now and edited some code to select the right architecture and edited the typo :)

thanks

@rickicode script seems unable to download OpenWRT image:

Maybe just missing something like wget $BD_URL/rootfs.tar.xz -O /var/lib/vz/template/cache/OpenWrt-$VER.tar.xz?
