The labs are Ok but i've collected several questions
1. How is ClusterIP assigned ? There is no info inside the calico.yaml. Probably the range is 10.0.0.0/8 ; Is it possible to configure - where?
2. The endpoints IP are from 192.168.0.0/16 range (calico.yaml). What about the following IP address:
kubectl exec nginx-6d48c9bcb8-5wlwp -- printenv | grep KUBERNETES ?? It seems 10.96.0.0/16. How is the IP assigned ?
What is the different between the epIP and 10.96.0.0/16 ?
3. As for lab 3.5 task 5, we create a new type of NGINX --> load-balance. I can make an access outside my cluster with IP of my NIC + the port. It's Ok. What about access to Web server (the lab 3.4 task 15). I can use the curl on the master node .It's Ok. Why cannot I use my NIC_IP:80 to access to the web-server ?
4. As for 3.5 task 9, we delete deployment + ep + service but we don't create ep+service. Does It mean as soon as a deployment is created ep/service are created too ?
May you have any links or materials about IP addresses of Kubernetes ?
Thank you in advance.
