so all you're trying to do is add some packages and a kickstart file?
I don't use any external tools. I add in the new packages into a directory
at the top level of the disc image and modify the Packages directory if I
need to. then I run createrepo on each "package" directory
createrepo --update -d -g comps.xml ${repo} trying to remember this, so
verify it's correct. if you want to use the comps/groups file, use the -g
option, otherwise ignore it.
In my kickstart, I add in the additional package directories as new repos
for yum to find the packages. after adding ANY rpms, you will need to
re-run createrepo on each folder and add them as repos in the ks file IF
you want anaconda to be able to install them. otherwise, you can mount in
the post and run rpm commands directly on each command.
to get additional data off of the disc, you will also need to ensure you
"mount" the disc/source somewhere the kickstart can access the data and
your anaconda/isolinux options must be set correctly, so you have to get
inst.ks and inst.stage2 setup properly.
inst.stage2=3Dhd:LABEL=3D${DRIVELABEL} inst.loglevel=3Ddebug lang=3Den_US.U=
TF-8
keymap=3Dus inst.ks=3Dcdrom:/dev/cdrom:/ks/${ksname}.ks
NOTE: inst.stage2 uses a label designation. this LABEL value MUST be
exact. When you generate your iso, usb drive, whatever, it MUST have the
label exactly matching the DRIVELABEL value or it won't install. Also, you
can use inst.upgrade to point to an upgraded anaconda Product.img file
which can contain rebrading/anaconda customizations.
Here's a kickstart snippet that covers a lot of ground:

# if you want to use a usb drive, then next part is mandatory:
#make sure the iso is bootable on USB devices
isohybrid ${filename}
implantisomd5 ${filename}
Apparently, you can use xorriso, which contains an argument for running
isohybrid.
hope that helps. All of this stuff for building your own respun disc is
available online.
Such as:
https://devopsmates.com/make-custom-centos-7-rhel-7-cd-kicktart-file/
http://www.smorgasbork.com/2014/07/16/building-a-custom-centos-7-kickstart-=
disc-part-1/
use livecd tools or dd to make a custom bootable disc/usb drive.

> Hello,<br>
><br>
> I=E2=80=99m trying to create a custom ISO with a Kickstart file to ach=
ieve a complete offline installation.<br>
><br>
> I was able to create the Kickstart file as usual, since I use it for P=
XE installs for at least 10 years, but the major problem now is building th=
e ISO with the necessary files.<br>
><br>
> I=E2=80=99ve came across a tool named Lorax, but I was not able to cre=
ate a custom ISO from DVD=E2=80=99s. It only works when point to mirrors, a=
nd this is a time consuming task. Another problem is that Lorax does not se=
ems to care about the /usr/share/lorax/product folder to create a custom An=
aconda with the embedded kickstart file on /usr/share/anaconda/<wbr>interac=
tive-defaults.ks.<br>
><br>
> The small ISO generated by Lorax lacks local repositories and I was un=
able to find the appropriate documentation on how to build this scenario. S=
o it generates a boot only install that must be done over the Internet.<br>
><br>
> At this moment I=E2=80=99m running Lorax on a CentOS install, I=E2=80=
=99ve got RHEL licenses too, but to keep it simple I just went with CentOS.=
I think this is irrelevant information but it=E2=80=99s just for the sake =
of completion.<br>
><br>
> With genisoimage I was able to add the custom product.img file, that I=
=E2=80=99ve generated by hand with cpio, on the ISO but I was not able to s=
olve the local repos problem. There are packages that I would like to add t=
o the install media, like Ansible, but they are available only on the Extra=
s repository and I=E2=80=99m unsure on how to do this. Just wondering if cr=
eaterepo and yumdownloader are necessary...<br>
