I installed concourse and then used the example job in the readme. Seems like the kubelet is not running.

- name: kind
  plan:
  - in_parallel:
    - get: k8s-git
    - get: kind-on-c
    - get: kind-release
      params:
        globs:
        - kind-linux-amd64
  - task: run-kind
    privileged: true
    file: kind-on-c/kind.yaml
    params:
      KIND_TESTS: |
        # your actual tests go here!
        kubectl get nodes -o wide

The logs are :-

[kubelet-check] It seems like the kubelet isn't running or healthy.
[kubelet-check] The HTTP call equal to 'curl -sSL http://localhost:10248/healthz' failed with error: Get http://localhost:10248/healthz: dial tcp 127.0.0.1:10248: connect: connection refused.

Unfortunately, an error has occurred:
	timed out waiting for the condition

This error is likely caused by:
	- The kubelet is not running
	- The kubelet is unhealthy due to a misconfiguration of the node in some way (required cgroups disabled)

If you are on a systemd-powered system, you can try to troubleshoot the error with the following commands:
	- 'systemctl status kubelet'
	- 'journalctl -xeu kubelet'

Additionally, a control plane component may have crashed or exited when started by the container runtime.
To troubleshoot, list all containers using your preferred container runtimes CLI, e.g. docker.
Here is one example how you may list all Kubernetes containers running in docker:
	- 'docker ps -a | grep kube | grep -v pause'
	Once you have found the failing container, you can inspect its logs with:
	- 'docker logs CONTAINERID'

 ✗ Starting control-plane 🕹️ 
Error: failed to create cluster: failed to init node with kubeadm: exit status 1

Can you help me with this issue ?

Hello @rohitsakala .

To maybe reproduce that issue please let me know:

  • the version of concourse you are using
  • where/how your concourse is running (locally on docker via docker-compose, deployed via BOSH release, ...)
  • a minimal pipeline that triggers this problem

Thanks!

Hi @hoegaarden,

  1. The version of the concourse is v5.3.0
  2. The concourse is deployed using BOSH a release. [0]
  3. I used the example pipeline in the Readme [2] of the repo. Example pipeline -

[0] https://github.com/cloudfoundry-incubator/cf-operator-ci/blob/master/docs/concourse-deployment-steps.md

Mh ... One thing I found was that running a cluster inside a task requires quite some resources, so when the workers are not quite beefy enough and other pipelines were running on the same concourse I saw some flakes similar to that.

Could you maybe test with a single node cluster? You could do that by either setting the KIND_CONFIG on your task or with a one-off task like this:

cat <<'EOF' > /tmp/kind.yml
kind: Cluster
apiVersion: kind.sigs.k8s.io/v1alpha3
nodes:
- role: control-plane
EOF

KIND_CONFIG="$(</tmp/kind.yml)" KIND_TESTS='kubectl get nodes -o wide' \
  fly -t <flyTarget> execute \
    --config kind.yaml \
    --privileged \
    --inputs-from 'kind-test/kind'

Currently, we run kind-on-c tests only on k8s (here) and it seems pretty stable (all of the recent failed & aborted runs are either fixed in kind-on-c or where infrastructure flakes). We also ran the same pipeline on a BOSH deployed concourse for a while, but we didn't see any fundamental difference and decommissioned that recently.

So I am not sure where your issue comes from. In the logs you provided I don't see anything standing out, but it might be useful to inspect the kubelet logs (something like: docker exec -ti kind-control-plane journalctl -f -u kubelet) of the failed cluster.

Hi @hoegaarden, I have also encountered this same issue in my concourse deployment. To jump start this discussion again, some additional context and logging are provided from my environment.

Issue

kind create cluster fail with the following errors. It fails at the control plan creation step, indicating that kubelet is not up and running:

✗ Starting control-plane 🕹️
ERROR: failed to create cluster: failed to init node with kubeadm: command "docker exec --privileged kind-control-plane kubeadm init --ignore-preflight-errors=all --config=/kind/kubeadm.conf --skip-token-print --v=6" failed with error: exit status 1
...

Conclusion

It appears that the none of the supported container runtimes including systemd, containerd or raw can handle creating the necessary containers.

@fyangd -- sorry for the late reply.

One thing I found, is that kind-on-c / kind had issues with on btrfs. A workaround has been implemented in be0268d, with that kind-on-c generally works on runway. However, especially compared to hush-house, kind-on-c is veeeerry falky on runway. I didn't get around digging deeper on why exactly that is.

If you are still interested, can you try to run your test with a recent version of kind-on-c?

hey @hoegaarden, thanks for getting back to me.

yes, I have seen the btrfs fix, and tried it on runway. It appears to be failing for some other reason. good to know that it's very flaky on runway.
