bpf-recorder is not valid for spod pods #1837

Closed shaojini closed 5 months ago

shaojini commented 1 year ago

What happened:

After installing SPO, when the verification of the bpf-recorder for its up and running is done, it shows an error: container bpf-recorder is not valid for the spod pod. When I try to enable it by patching the spod configuration, all pods of spod have been crashed without able to successfully restart.

What you expected to happen:

The bpf-recorder is up and running.

How to reproduce it (as minimally and precisely as possible):

Hey @shaojini, thank you for the report. CAn you extract the crash logs of the spod instances, like spod-28qd6?

Hi, @saschagrunert .

Any comment for this issue? Thanks.

saschagrunert commented 1 year ago

@shaojini we need to find out why the pod has been crashed, while the logs on https://github.com/kubernetes-sigs/security-profiles-operator/issues/1837#issuecomment-1682228753 do not indicate any crash at all. Do you have the logs of the crashing pod somehow available?

shaojini commented 1 year ago

Hi, @saschagrunert .

I have tried uninstalled and re-installed a few time, but the problem is the same. The logs given previously is taken from one of those tries (Before reporting the issue, I have tried at least twice to confirm it). The restart of pods may be normal because the patching on those spod pods has been done (the name of spods has been changed). However, the restart of "crash" pods can not been done successfully (describe of spod can find some information?):

@shaojini you can see that the bpf-recorder has the container id 1f26b655d092359cbd22fc47a72a6f065b0faee1cd92f44b542a5bb129241f62 from kubectl describe. May I ask you to access the node and run something like sudo crictl logs <ID> to get the logs of the crashing container?

Hi, @saschagrunert .

I have re-operated the issue again for comparing the "describe pod spod-xxxx" before and after the patching. The difference is to enable "recording" in the "daemon" and create one extra container of "bpf-recorder" in the spod. In addition, the Container IDs (cri-o) of security-profiles-operator and metric have been changed:

From the logs of the node (re-installing has been done), the error is the "container ID does not exist":

root@k8s-worker3:~# sudo crictl logs 723ec7f3c3c798953fa217bed812ac179352bbe11a27597d6568458ad41efe9e

shaojini commented 1 year ago

Hi @saschagrunert .

That ID in the "describe" is not the actual container id. I got the ID in this way:

root@k8s-worker3:~# crictl ps -a

CONTAINER           IMAGE                                                                                                                               CREATED             STATE               NAME                         ATTEMPT             POD ID              POD
a8fefdb4a1664       gcr.io/k8s-staging-sp-operator/security-profiles-operator@sha256:40f98b564084d46acac519a515032e5602b6eec480d221771053c96f4057811d   2 minutes ago       Exited              bpf-recorder                 53                  70487bf0e53cc       spod-2v9z7

Then to get the error from the logs of the container ID:
root@k8s-worker3:~# sudo crictl logs a8fefdb4a1664
..............................................................................

Because it tries to restart all time, the container id also changes all the time. Therefore, the logs of the ID can not be found after a few minutes.

saschagrunert commented 1 year ago

@shaojini the previous logs of the container should be still available somehow, see kubectl logs --previous. At least for a few minutes as you'd mentioned.

shaojini commented 1 year ago

Hi, @saschagrunert.

The bef-recorder container log has shown the error: "error"="connect to metrics server: connect to local GRPC server: wait on retry: timed out waiting for the condition".

Is it the root cause for the unsuccessful staring-up of the bef-recorder container according to the logs? Do you have the same issue when you config the bef-recorder for recording?
