Centos 7 ISO Builder
This repo allows one to create a custom CentOS 7 ISO with the necessary packages and tooling for deploying on SmartOS and the Joyent Public Cloud.
Requirements
In order to use this repo, you need to have the following:
- SmartOS
- A running CentOS instance (physical or virtual) with spare disk space
- sdc-vmtools
Setup
Included is a setup_env.sh script to be run inside the CentOS instance. This
script will install the necessary packages required to create a custom ISO.
Using
The next script is create_iso which takes a series of commands:
- fetch
- layout
- finish
fetch
This command will fetch the DVD ISO from a given URL (default is Stanford) if no currently found.
layout
This command will extract the ISO and place it onto disk and copying any
custom RPMS in ./RPMS onto the layout.
finish
This command will cleanup all prior ISO metadata, copy over the kickstart file
in ./ks.cfg, modify the boot menu to add the kickstart file, and
creates the ISO in ./iso.
You can run each command separately or all together.
./create_iso fetch
# create RPMs
./create_iso layout
./create_iso finish
Or ./create_iso fetch layout finish.
The resulting ISO will be ready to boot and install a clean image ready for SmartOS and the Joyent Public Cloud.
