[Question/Help] Air Gap

[nemonik]

k3s supports air gap deployments... But I don't see this as possible with k3d "managing" a cluster.... I can pass the image k3s image param on start up, but this wont cover all the other images k3s retrieves https://github.com/k3s-io/k3s/releases/download/v1.21.2%2Bk3s1/k3s-images.txt to spin up.

Hi @nemonik , thanks for starting this discussion!
You can certainly try this, it just requires some manual work (like k3s airgap does as well):

• create your own k3s image: with FROM rancher/k3s:<version> and copy your image tarball into the filesystem as per https://rancher.com/docs/k3s/latest/en/installation/airgap/#prepare-the-images-directory-and-k3s-binary
• use that image with k3d: k3d cluster create --image your/k3s:tag

That's how I imagine it should work (at least I don't see why it shouldn't 🤔).

This is assuming, that you have the rancher/k3d-proxy image required for cluster creation (and potentially the rancher/k3d-tools image) available on the target host, which are the other two images used by k3d.

I honestly hadn't thought to do that, but you are right it is essentially what you would do for k3s. Thank you.

Do you have any working example of Dockerfile?
