helm: Add SA to nodeinit ds #24836

darox · 2023-04-12T11:25:46Z

This commit is to make sure that users can enable/disable SA token auto
mount, which is recommended in NSA security hardening guide. This PR is for the cilium-nodeinit daemonset.

One small comment as per below, the rest looks good to me. Thanks.

Thanks! Could you elaborate why this is needed/what the intended use-case is? Especially since we seem to be enabling this by default with this commit.

Sure. A EE customer is asking for it. As it was already added for the other deployments / daemonsets in this commit 0685982. We can also disable it by default. So that the nodeinit mounts the default SA.

Thanks! I did a quick check at the used startup scripts and if they need any non-standard RBAC permissions, but does not seem to be the case.

Helm smoke test still red: https://github.com/cilium/cilium/actions/runs/4678821697/jobs/8288020398?pr=24836

It doesn't say what exactly the issue is though. Try running 'make -C install/kubernetes' locally and see if there are any changes to the generated files maybe.

@darox The test failures in the extended test suite on AKS, EKS and GKE (all using nodeinit) look legitimate. All cilium-agents seem to be stuck in the wait-for-nodeinit init container.

I will have a look at it. Thx

@gandro How can I find out more about the tests?

Did some on EKS and kind.

Just made some manual tests and can't confirm the behavior:

Just made some manual tests and can't confirm the behavior:

The cluster you shared does not look healthy, but it seems to have created the service account at least.

Can you share the instructions you've used? Generally speaking, I would expect this to be reproducible if you use the Helm chart from this branch and the necessary ENI Helm fags. The workflow file shows the commands we're using in CI:

https://github.com/cilium/cilium/actions/runs/4690762173/workflow

It's going through the Cilium CLI (which pulls in the Helm chart), that could be another potential cause. But I would validate purely the Helm chart first.

darox · 2023-04-19T09:40:18Z

I still couldn't reproduce it:

Create cluster with same k8s version as CI
eksctl create cluster --region=eu-central-1 --version=1.23
Clone https://github.com/darox/cilium and checkout add-sa-options-nodeinit
git clone https://github.com/darox/cilium/tree/add-sa-options-nodeinit && cd cilium && checkout add-sa-options-nodeinit
Change to helm chart folder and apply
cd install/kubernetes/cilium/ && helm install --generate-name -n kube-system -f values.yaml .

Values.yaml looks like this, i.e. adapted to what is configured in CI:

Thanks! Yeah the Helm chart itself looks good. I think the issue is with the Cilium CLI. I was able to reproduce the issue on Kind:

$ git rev-parse --abbrev-ref HEAD
add-sa-options-nodeinit

For some reason the node init daemonset is not deployed that way. Looks like a bug in Cilium CLI, I can even reproduce this with the main chart 🤔

OK, I haven't tried with cilium CLI and nodeinit.enabled=true. I assume we will wait with merging till this bug is fixed?
