Custom images

You can create custom images using Image Builder.

Download the image builder from:<version>/targets/x86/64/nethsecurity-imagebuilder-<version>-x86-64.Linux-x86_64.tar.xz

Replace version with the latest release, like 23.05.06.

Using Image Builder inside CentOS 7

Install the dependencies:

yum install perl-Thread-Queue devtoolset-7-make git unzip bzip2

Upload the builder inside the system and prepare it:

mkdir builder; tar xvf nethsecurity-imagebuilder-22.03.0-x86-64.Linux-x86_64.tar.xz -C builder
cd builder
sed -i '/logd \\/d' include/

Note: OpenWrt build system assumes logd is always installed, but NethSecurity image does not ship it. The sed command ensure logd is not bundled inside the image.

Prepare the files directory:

tar xvf master.tar.gz nethsecurity-master/files/

To include custom files, add them inside nethsecurity-master/files directory with the full path, like:

echo "hello" > file/root/goofy

Start the build with all included packages:

source /opt/rh/devtoolset-7/enable
make image  FILES="nethsecurity-master/files/" PACKAGES="$(grep "Package: " packages/Packages | cut -d ':' -f 2 | tr '\n' ' ')"
