A tool that makes it easier to get started when deploying OpenShift clusters in a disconnected / air-gapped networks. The tool will bundle up all of the required dependencies (e.g. container images, CLI tools, etc.) that can be transfered to the disconnected environment. The generated bundle includes a script to unpack and host the artifacts in the disconnected environment so that they can be used to install OpenShift.
For a walkthrough of how to use the tool, including deploying a simulated disconnected environment, take a look at the docs.
