Hi all,

When I check the interfaces in both nodes, I don't see the interface cni0 in a worker node (it appears only in a master node). In the Lab document appears the following line:

9. View the networking on the master and second node. You should see a docker0, cni0, and a flannel.1 interface

among others.

In my Master node:

2: eth0:

3: docker0:

4: flannel.1:

5: cni0:

6: [email protected]:

In my worker node (after join to cluster):

2: eth0:

3: docker0:

4: flannel.1:


Best regards,

    Yes, this is true if you have not yet created any containers on the new system. I will update the material to reference this. I must have run step 10, then looked back. Please run a Pod with enough replicas to use both nodes and let us know if the interface has been created.
