vpc cni - aws-eks-nodeagent log clarification

shabbskagalwala commented 10 months ago

What happened:

I recently upgraded one of my homelab clusters to 1.25 from 1.24 and am seeing log messages from the aws-eks-nodeagent sidecar on the aws-node daemonset

✗ k logs -f -n kube-system -c aws-eks-nodeagent aws-node-fczsz
{"level":"info","ts":"2023-10-18T20:40:52.456Z","caller":"runtime/asm_amd64.s:1598","msg":"version","GitVersion":"","GitCommit":"","BuildDate":""}
2023-10-18 20:40:52.462361271 +0000 UTC Logger.check error: failed to get caller
2023-10-18 20:40:52.462410354 +0000 UTC Logger.check error: failed to get caller

Everything looks good the nodes are ready, the pods seem to be working fine. But just not sure what this error log means and if it is of any concern.

Note: This add on is a managed add on and not installed manually.

      - args:
        - --enable-ipv6=false
        - --enable-network-policy=false
        - --enable-cloudwatch-logs=false
        - --enable-policy-event-logs=false
        - --metrics-bind-addr=:8162
        - --health-probe-bind-addr=:8163

From some previous issues I did see that the network policy not being set was the issue but that arg is being set.

Seeing this on add on versions

v1.15.1-eksbuild.1
v1.15.3-eksbuild.1

Also these are all the CRD's installed based on previous issues

✗ k get crd | grep -i aws

Configuration on the managed add on

{"env":{"MINIMUM_IP_TARGET":"10","WARM_ENI_TARGET":"0","WARM_IP_TARGET":"2"}}

Please let me know if i can provide any further information. Thank you!

Those logs are not of any concern. It is coming from the zap logger utility. We will fix it to avoid any such confusions.

@jayanthvn got it - thank you for confirming! That answers my question. Closing this 👍
