Installing the Db2 Operator in an air-gapped environment

There are two ways of installing the Db2 Operator in an air-gapped environment, either through a bastion host or by transferring it to the cluster from a portable device.

Background

In production, it is common to have a cluster that does not have internet access. You can install Db2 Operator and OpenShift Container Platform in an air-gapped (otherwise known as offline or disconnected) cluster environment. Air-gapped installations require that you mirror a typical online installation by using images in your own registry.

The following diagram provides an overview of air-gapped installation scenarios for portable compute, portable storage, and bastion hosts:

All of these scenarios use operator package files to mirror content from a source to a target.

You can store the product code and images in a file system (such as a portable compute device or portable storage device), or in a bastion host, and then transfer them to a local air-gapped network. If you are using a file system, you don't need a bastion host to install in your air-gapped environment.
