FailedCreatePodSandBox with Kubernetes+Kata+Firecracker

[cameronsenese]

Description of problem

Unable to schedule pods via Kubernetes using Containerd+Kata+Firecracker.

Kubernetes RuntimeClass:

apiVersion: node.k8s.io/v1beta1
kind: RuntimeClass
metadata:
  name: kata
handler: kata

Expected result

Submitting the following:

apiVersion: v1
kind: Pod
metadata:
  name: nginx-kata
spec:
  runtimeClassName: kata
  containers:
  - name: nginx
    image: nginx

launches pod nginx-kata.

Actual result

Submitting the following:

apiVersion: v1
kind: Pod
metadata:
  name: nginx-kata
spec:
  runtimeClassName: kata
  containers:
  - name: nginx
    image: nginx

does not launch pod nginx-kata. Pod is stuck at ContainerCreating.

Further information

When Kata is configured to use qemu, the operation to create pod nginx-kata (per above) is successful. Issue limited to Firecracker.

I'm running into the same issue - using other hypervisors like clh works just fine, but I actually need to use the fc one. Any help is appreciated 🙏

[prateeksahu]

I am running into the same issue as well. Is there any update on this front?

[jodh-intel]

This looks like the issue I raised recently. Specifically see #2818 (comment).

[prateeksahu]

@jodh-intel Thanks for pointing that out!
Just to clarify, my setup is using cri-o and am still getting the same issues.
Regardless, are there any working instructions to configure the devmapper etc so that we can get it working currently? I do want to use firecracker vms

[jodh-intel]

The two links in my comment give you some instructions, but since there are various ways to configure FC, it's "up to you" I think ;) I used the scripts on https://blog.cloudkernels.net/posts/kata-fc-k3s-k8s/ that use loopback devices. These were fine for my testing, but probably not what you want for a "proper" setup.

I think @ananos was planning to write some DM docs for FC for Kata at some point, but for now I'd use the references above to get you going, or speak to the Firecracker folk directly for advice.

[ccrvlh]

Having a similar issue using rke2 and kata-deploy, although no hypervisor works, and the message is slightly different:

Failed to create pod sandbox: rpc error:
code = DeadlineExceeded
desc = failed to create containerd task: failed to create shim task: context deadline exceeded

From the docs it looked like it should work without further configuration, wonder what else might be needed to make it work.
