I searched around a bit and couldn’t find any published kickstart files around for CentOS 7 (and the ones I did, didn’t work correctly and looked overly complex), therefore I’m attaching my CentOS 7 minimal kickstart file for anyone else who may be searching for one!

Notes:

1) Firewall service and selinux are disabled in this kickstart file (for testing). Please change them to enabled if preferred.
2) Filesystem is XFS with LVM
3) Update url and repo with your local mirror if preferred.

Please let me know if you have any issues or have suggestions to improve the above CentOS 7 minimal kickstart file.
