Preparing the Air-gapped environment#

After preparing the Assets VM and downloading the necessary assets, the fetched data needs to be made available in the Air-gapped environment. Two options are available:

  1. Move the system that was used to prepare the Assets VM to the Air-gapped environment. For instance, if it is a laptop or a VM, you can move to the Air-gapped environment by changing its network configuration.
  2. Copy the data from the system that was used to prepare the Assets VM to the Air-gapped environment using a USB key or a temporary network connection. The data should include:
    • The playground repository cloned during the "Preparing for installation" step.
    • The edaadm repository which includes the eda-cargo folder holding the Air-gapped data (bundles, asset VM image and Talos base VM images). The eda-cargo folder was populated during the preparing the Assets VM and downloading the necessary assets steps.

Loading the Kpt Setters image#

Note

These steps are to be executed in the air-gapped environment.

The procedures for setting up the Assets VM and installing EDA use Kpt - a package manager for Kubernetes. Kpt relies on the kpt-apply-setters container to be present in the local Docker image cache of the air-gapped system to be able to perform its operations.
The container image is part of the eda-bundle-tools bundle in the edaadm/bundles list. If you used the save-all-bundles option when downloading the assets, you will have that bundle on your air-gapped system. If you do not have it yet, you can download the bundle on the system with Internet and copy over the content of the bundle to the air-gapped environment before executing the steps.

To load the kpt-apply-setters image from the eda-bundle-tools bundle, follow these steps:

  1. Go to the edaadm repository directory.

    Change into the edaadm repository that you have copied from the Internet-connected system:

    cd path/to/edaadm

  2. Import the image into the local docker image cache

    Note that the version of the bundle might update to a newer version in the future. In that case, replace the 1-0-0 with the appropriate version and the correct kpt-apply-setters version as well.

    docker load -i ./bundles/eda-cargo/eda-bundle-tools-1-0-0/images/srl-labs-kpt-apply-setters-0-1-1
