Ex 4.1
Regarding 4.1, I don't have any cni.log file in my nodes. Is this bad?

Hi @suser,
What network plugin do you have installed in your cluster? What is your Kubernetes release version and the OS of your nodes?
Under Ubuntu 18.04 LTS with Kubernetes 1.19.0 and 1.20.1, and Calico as CNI plugin, logs are saved by default under the path shown in Lab 4.1 Step 1, and this is the
log_file_path
set in the/etc/cni/net.d/10-calico.conflist
CNI configuration file for the Calico plugin.Regards,

Thanks Chris. indeed my env is Ubuntu 18.04 LTS with Kubernetes 1.19.0, and I found the file /etc/cni/net.d/10-calico.conflist but there is no entry log_file_path:
$ cat /etc/cni/net.d/10-calico.conflist
{
"name": "k8s-pod-network",
"cniVersion": "0.3.1",
"plugins": [
{
"type": "calico",
"log_level": "info",
"datastore_type": "kubernetes",
"nodename": "kmaster",
"mtu": 1440,
"ipam": {
"type": "calico-ipam"
},
"policy": {
"type": "k8s"
},
"kubernetes": {
"kubeconfig": "/etc/cni/net.d/calico-kubeconfig"
}
},
{
"type": "portmap",
"snat": true,
"capabilities": {"portMappings": true}
}
]
}This means my system is missing some plugin?
Thanks again!
Stefan

Hi @suser,
Calico is the plugin in this case. If the
kubectl describe pod | grep cni
command returns a list of Annotations with IP addresses from the default Calico pool192.168.0.0/16
then it should be working as expected. The missinglog_file_path
may be just a misconfiguration of the plugin, possibly tied in with your lab environment's setup.When pasting code into the forum, you can use the Code option from the Format menu (the reversed P) to make code more legible, and to preserve indentation and overall formatting.
Regards,
