The install scripts are idempotent. Re-run the scripts with different flags to change the behavior of the installer.

Flag Usage
airgap Do not attempt outbound Internet connections while installing.
ha Install in multi-master mode.
load-balancer-address IP:port of a load balancer for the K8s API servers in ha mode.
public-address The public IP address.
installer-spec-file This flag takes the path to a ‘patch’ yaml file. The config in this patch will be merged with the existing installer yaml, taking precedence where there is conflict, and will change the installation based on the final config.
preserve-docker-config This flag will make the kURL installer keep the current docker config of the node, overriding any yaml config
preserve-selinux-config This flag will make the kURL installer keep the current Selinux config of the node, overriding any yaml config.
preserve-firewalld-config This flag will make the kURL installer keep the current Firewalld config of the node, overriding any yaml config.
preserve-iptables-config This flag will make the kURL installer keep the current Iptables config of the node, overriding any yaml config.
