Airgap w/Zarf📜

⚠️ This is a work in-progress.

Requires Big Bang 1.54.0 and greater.📜

This section is currently purely devoted to building and testing packages on a development cluster. The result could be a set of archives that can be used for moving across an airgap. Essentially, this automates a few of the steps indicated in this documentation.

The first step would be to stand up a Big Bang dev cluster. This is most easily represented by following the steps outlined here, but would ultimately result in running the below command, which stands up a larger development cluster. Take note of the KeyName and Public IP address which will be used in a later step.

docs/assets/scripts/developer/k3d-dev.sh -b

Be sure to export your Registry1 credentials next as seen in the following:

export REGISTRY1_USERNAME=<username>
export REGISTRY1_PASSWORD=<password>

Now you can execute the following, which will automatically detect your SSH key location, name and Public IP, based off the current AWS_PROFILE declared locally: 

docs/assets/scripts/airgap-zarf/zarf-dev.sh

The above will clone the latest main branch of the defenseunicorns/zarf repository and execute the stock examples/big-bang/zarf.yaml. If you want to use a different zarf.yaml, you can override this by setting any of these variables ahead of time, either by exporting them or setting them as part of the command.

  • ZARF_TEST_REPO: sets the repository to clone from.
  • ZARF_TEST_REPO_BRANCH: sets the branch to switch to from the cloned repo.
  • ZARF_TEST_REPO_DIRECTORY: sets the directory where the desired zarf.yaml is.

Also since this all uses the same dev script, you should be able to use whatever k8s tooling (such as kubectl or k9s) you already might use on a dev cluster as KUBECONFIG is still transferred locally and available.
