Lab3.4 Calico doesn't work in worker node? Differents IP Ranges

Hello everyone.
I'm doing the lab3.4. I've installed in GCE a master node and in other Instance a controller node.
I use crio like a container engine.
When I create any pod in the Controller node the Endpoint IP range is 10.88.0.0, mean while the PODs created in master node have Endpoint with range 192.168.X.0 like it was definid by calico (I think)
[email protected]:~$ kubectl get pod -o wide NAME READY STATUS RESTARTS AGE IP NODE NOMINATED NODE READINESS GATES nginx-55d5bfd679-4pvqs 1/1 Running 0 4s 10.88.0.8 worker <none> <none> nginx-55d5bfd679-b7h9r 1/1 Running 0 3h8m 10.88.0.6 worker <none> <none> nginx-55d5bfd679-l5c4v 1/1 Running 0 3h8m 192.168.219.68 master <none> <none>
I don't hace access to 10.88.0.8 or 10.88.0.6, but I can access to 192.168.219.68
[email protected]:~$ telnet 192.168.219.68 80 Trying 192.168.219.68... Connected to 192.168.219.68. Escape character is '^]'.
[email protected]:~$ telnet 10.88.0.8 80 Trying 10.88.0.8...
[email protected]:~$ telnet 10.88.0.6 80 Trying 10.88.0.6...
Should the PODs contained in the Controller node have the range 192.168.X.0 as well?
Thank sou much.
Regards.

User created Pods should be assigned IP addresses from the Pod IP block managed by Calico, regardless of the node where they get deployed.
You can try to run
kubectl describe pod <pod-name>
against one of the pods with a192.168.x.x
IP address and against one of the pods with the10.88.y.y
IP address, and look at theannotations
section, it my give you clues where the IP address is coming from.Regards,

Hello chrispokorni!!
First of all, thank you for your help.
Today, when I've powered on the GCE Instances, the Controller node's POD has the correct IP RANGEs. I supposed that the system reboot solved it. Could be?Name: nginx-55d5bfd679-2rwcj Namespace: default Priority: 0 Node: worker/10.2.0.5 Start Time: Tue, 24 Nov 2020 11:50:53 +0000 Labels: app=nginx pod-template-hash=55d5bfd679 Annotations: cni.projectcalico.org/podIP: 192.168.171.69/32 cni.projectcalico.org/podIPs: 192.168.171.69/32 Status: Running IP: 192.168.171.69 IPs: IP: 192.168.171.69
Have a nice day
