Question 14 | Find out Cluster Information

 

You're ask to find out following information about the cluster k8s-c1-H:

  1. How many master nodes are available?
  2. How many worker nodes are available?
  3. What is the Service CIDR?
  4. Which Networking (or CNI Plugin) is configured and where is its config file?
  5. Which suffix will static pods have that run on cluster1-worker1?

Write your answers into file /opt/course/14/cluster-info, structured like this:

 

Answer:
How many master and worker nodes are available?

We see one master and two workers.

 

What is the Service CIDR?

 

Which Networking (or CNI Plugin) is configured and where is its config file?

By default the kubelet looks into /etc/cni/net.d to discover the CNI plugins. This will be the same on every master and worker nodes.

 

Which suffix will static pods have that run on cluster1-worker1?

The suffix is the node hostname with a leading hyphen. It used to be -static in earlier Kubernetes versions.

 

Result

The resulting /opt/course/14/cluster-info could look like:

Write all those context names into /opt/course/1/contexts . Next write a command to display the current context into /opt/course/1/context_default_kubectl.sh , the command should use kubectl . Finally write a second command doing the same thing into ...
