Installing in an air-gapped environment
If your cluster is not connected to the internet, you can install IBM Cloud Pak® for Integration in your cluster by using either a bastion host, portable compute device, or a portable storage device.
Overview: Installing in an air-gapped environment
In production, it is common to have a cluster that does not have internet access. In these cases, you can still install IBM Cloud Pak for Integration, other IBM Cloud Pak® solutions, and OpenShift Container Platform in an air-gapped (otherwise known as offline or disconnected) environment. Unlike online installations, air-gapped installations require you to enable the IBM Operator Catalog to mimic a typical online installation 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 Container Application Software for Enterprises (CASE) files to mirror content from a source to a target. CASE is a specification that defines metadata and structure for packaging, managing, and unpacking containerized applications.
You can store the product code and images to a portable compute device (like a laptop), portable storage device (like an external hard disk drive), or a bastion host and then transfer them to a local air-gapped network. If you are using either a portable compute device or a portable storage device, you don't need a bastion host to install in your air-gapped environment.
