DATA to Backend failed, after agent restart

Hi @Avatat, Given KAS <-segment 1-> Konnectivity Server <-segment 2-> Konnectivity Agent. Is segment 1 configured with http-connect, grpc over https or grpc over uds? You can find the answer in the /etc/srv/kubernetes/egress_selector_configuration.yaml file.

[Jefftree]

Hello, looking at the logs it seems that the failure is all tied to one request (id=3). Currently, when a connection is broken and re-established while a data transmission is in progress, the entire request data needs to be retransmitted (the apiserver should handle most of these retries).

Do requests made specifically after the agents reconnect exhibit this behavior as well?

[cheftako]

Not sure if its the same issue. Trying to reproduce I improved our test infra (#124). Set to making two requests with a 10 second delay and restarted the agent between the first and second request. The client clearly gets stuck. Server log is

$ kubectl logs -n kube-system metrics-server-7f6d95d688-4jm9g -f
Error from server: Get https://.../containerLogs/kube-system/metrics-server-7f6d95d688-4jm9g/metrics-server?follow=true: rpc error: code = Unavailable desc = connection error: desc = "transport: Error while dialing dial unix /etc/kubernetes/konnectivity-server/konnectivity-server.socket: connect: no such file or directory"

If the UDS socket is missing that seems to be an issue with the konnectivity server, before even reaching the step to dial to the agent. Are you observing any restarts/crash loops/errors for the konnectivity server before you intervene manually?

Also noticed you have the -f flag for logs. Was this command ran after the agent reconnect or before?

$ kubectl top nodes
Error from server (ServiceUnavailable): the server is currently unable to handle the request (get nodes.metrics.k8s.io)

I was able to reproduce this and this one should be related to the bug described earlier. Will do some more testing to get a fix.

[Avatat]

I have issues with HTTP and HTTPS protocols: kubernetes/kubernetes#92690

Now I use konnectivity-server and kube-apiserver in one pod together, and they use GRPC over UDS.

[Avatat]

Yes. After agents restart (not only reconnect) I lost communication from KAS to cluster services behind Konnectivity tunnel.
After KAS+Konnectivity-server (they are in one pod) restart, everything backs to normal.

[Avatat]

Looks very similar :)
If you prepare a fix, I would like to test it on my case, but I will need a Docker image.

[Jefftree]

Per #108 we removed retrying when server -> agent connections fail. I think the case in both your scenarios is that the same tunnel (and dialer) is used when the first connection is established, as well as throughout the agent disconnect and reconnect phase. The dialer/tunnel will still map to the old agent since we don't do any reconciliation without the retry step. Using a new dialer/tunnel and retrying the request should be the fix, but existing connections have no understanding that their tunnels are broken.

@cheftako @caesarxuchao we should propagate an error to the client if too many backend.Send() errors pop up and either force the connection to be dropped or change the backend (https://github.com/kubernetes-sigs/apiserver-network-proxy/blob/master/pkg/server/server.go#L297). This is especially an issue for long lived requests and connections with a large body of data since we don't have the notion of cancelling a request.

[Avatat]

@Jefftree, thank you for the explanation!

Probably I don't understand how KAS works and do the requests, but the connection isn't working even when I try to do kubectl logs pod_name after konnectivity-agent restart. As I understand, KAS should make a new request/connection through Konnectivity tunnel, but it still can't.
Maybe KAS uses a single connection to do all requests?

[Jefftree]

Hmm that's weird. KAS creates a new tunnel for each log request, so it's possible you're running into a different problem. Just confirming, this is GRPC over UDS?

[Avatat]

I use below egress configuration:

apiVersion: v1
data:
  egress-selector-configuration.yaml: |
    apiVersion: apiserver.k8s.io/v1beta1
    kind: EgressSelectorConfiguration
    egressSelections:
    - name: cluster
      connection:
        proxyProtocol: GRPC
        transport:
          uds:
            udsName: /etc/kubernetes/konnectivity-server/konnectivity-server.socket
kind: ConfigMap
metadata:
  name: egress-config

KAS and konnectivity-server containers works in one pod and they share /etc/kubernetes/konnectivity-server directory (as emptyDir volume).

[Avatat]

I observed one more thing:
After konnectivity-agent restart I'm getting:

$ kubectl logs -n kube-system metrics-server-7f6d95d688-4jm9g -f
Error from server: Get https://.../containerLogs/kube-system/metrics-server-7f6d95d688-4jm9g/metrics-server?follow=true: rpc error: code = Unavailable desc = connection error: desc = "transport: Error while dialing dial unix /etc/kubernetes/konnectivity-server/konnectivity-server.socket: connect: no such file or directory"

and:

$ kubectl top nodes
Error from server (ServiceUnavailable): the server is currently unable to handle the request (get nodes.metrics.k8s.io)

After konnectivity-server container restart, kubectl logs ... is now timeouting, and kubectl top ... stays the same.

After KAS (hyperkube) container restart, everything backs to normal and both commands work.

[zanetworker]

We saw similar issues, was not sure what causes it. Could this also be related to the serverCount parameter ?

[Avatat]

@cheftako, @Jefftree, thank you for your effort!
I built konnectivity-server image with @Jefftree change ^ and I think that it solves the issue. Can't wait for the release with the fix :)

[Avatat]

But still, it isn't perfect. After some time and few agent restarts, I'm getting:

kubectl --kubeconfig config_dar0908prod logs -n kube-system kube-proxy-tx9sp
Error from server: Get https://...:10250/containerLogs/kube-system/kube-proxy-tx9sp/kube-proxy: dial timeout

After everything gets stuck, logs look like below:

It's weird because from the konnectivity-server site we can see DIAL_REQ and then series of 46 bytes DATA, but on the konnectivity-agent site we can see only DIAL_REQ and everything later is stuck, no DATA.

It happens every kubectl logs ....

Definitely there is something wrong with DIAL_REQ between konnectivity-server and konnectivity-agent.

EDIT:
I noticed that kubectl logs works for pods which are scheduled on the same node as konnectivity-agent pod. I will dig it deeper.

@Avatat I had the same issue with having the konnectivity-agent as a deployment, turned it into a daemonset worked much better, still I didn't get down to why as a deployment it was stuck sometimes.

Thank you!
I thought the same and I've tried deployment and daemonset too - I didn't see any difference :(

Ok, I found why kubectl logs didn't want to work. The reason is simple and obvious - firewall on my nodes, allow traffic to kubelet (10250 TCP) only from KAS network. When Konnectivity tunnel was established to the agent on node A, it can't reach kubelet at node B, because the firewall was dropping communication.

Yup. We have a nice to have feature files to try to get the traffic to at least be sent to the correct failure zone (and better yest the right node). However there is benefit to not requiring the traffic have to land on the correct node. The most obvious is that as long as traffic doesn't have to land on the right node, then you can kubectl logs the agent, when its having problems.
