SNO (Single-Node OpenShift) Bootstrap

Generate custom ISO with embedded ignition config to bootstrap a SNO deployment. install-config.yaml in, custom ISO out.

Repo automates these steps outlined in the OpenShift documentation.

This script was built for RHEL 8. I haven't tested other RHEL versions, other distros, or MacOS.

Generate ISO

No prerequisites are required to run create-iso.sh. The script will download openshift-install, coreos-installer, and the RHCOS live image. If you run the script multiple times, it will used the previously downloaded copies of the installers/ISO.

Prior to starting you'll need to know:

• Your JSON pull secret
• Your SSH public key (optional)

To generate the ISO:

$ cp install-config.template.yaml install-config.yaml
# Edit install-config.yaml; Replace sections marked "REPLACE_ME"
$ ./create-iso.sh
