Running software in an airgapped environment is difficult, but the hardest thing is the install, packaging and shipping updates. I have used https://zarf.dev/ to do this for a government client, and it was an amazing experience. I highly recommend it. K8s seems heavy, but if you want to run datastores with backups (k8s operators), or highly customised environments, and automate all of that, instead of loads of bash and custom code, it shines.
