How do I create the repository for my custom distro?

Question

I am creating a proof of concept distro for CentOS and for the moment would just like to install the @base and @core packages for my distro. I have my kickstart file configured to boot into a text installer, but I'm struggling to figure out how to get the installer to find my packages on my ISO.

I have found the syntax for --repo in the kickstart, but I'm not entirely sure what file I'm actually looking to reference to. I also am aware of using the createrepo command, but not sure how this would help as I have the standard repo files from the original CentOS 7 ISO and I'm not yet trying to add my own rpm's.

I have attached 2 screenshots, one of the GUI installer and one of the text installer. These should be exactly the same error, I don't have a source for my packages on my ISO. The packages are there, but I don't know how to tell the installer to find @base and @core packages that I copied over from the original CentOS ISO.

edit: In case it's helpful here is my current kickstart file:

install
cdrom
text
keyboard us
lang en_US.UTF-8
rootpw --iscrypted $6$XRIetvtFyLXRFVzZ$jX7xRxsN6M.DIqwJ9DQui9ytaqK3IAzauSqB4zeRNvMKJo6xCJQAk90XIaxh.SBn0IBtyZM7ZlHK8eSk55VnG0
timezone America/Denver --isUtc

#partitioning
clearpart --none --initlabel
autopart --type=lvm

#bootloader info
bootloader --location=mbr --driveorder=sda

%packages
@core
%end

If I understand your problem correctly... you need to reference a repo that is an iso. I'll give you a few examples that will hopefully help. So if you're installing off a cdrom you would use:

   repo --name="CentOS" --baseurl=cdrom:sr0 --cost=100

(This assumes your cdrom is sr0, its possible it could be a different device. Check /dev to be sure)

And if you're installing off a mounted iso:

   repo --name="CentOS" --baseurl=file:///path/to/mounted/iso --cost=100
