How to increase Pods limit per worker node in Kubernetes

Solution: First We need to take a look at Grafana dashboard to see if the nodes are able to receive more pods in terms of infrastructure resources (CPU/RAM, ....), then calculate the average of this resource utilization in order to determine the new value of pods limit on each node.   We suppose that the chosen value for the pods limit on nodes is 200, you can change it following these steps :     1.    Connect: First connect to the node (the worker with the issue):                                                                    $ ssh -i /path/to/your/ssh-key/id_rsa node-user@node-hostname node-user@node-hostname:~$ sudo -i  root@node-hostname:~#     2.    Edit:
