Performing an air gap installation
If your cluster is not connected to the internet, you can install Operational Decision Manager in your cluster via connected or disconnected mirroring.
About this task
If you have a host that can access both the internet and your mirror registry but not your cluster nodes, you can directly mirror the content from that host machine. This process is referred to as connected mirroring. If you have no such host, you must mirror the images to a file system, and then bring that host or removable medium into your restricted environment. This process is referred to as disconnected mirroring.
