A Kubernetes cluster consists of a control plane plus a set of worker machines, called Nodes, that run containerized applications. Every cluster needs at least one worker node in order to run Pods.
The worker node(s) host the Pods that are the components of the application workload. The control plane manages the worker nodes and the Pods in the cluster. In production environments, the control plane usually runs across multiple computers and a cluster usually runs multiple nodes, providing fault-tolerance and high availability.
To use the Kubernetes connector, the following connection data is required:
·Hostname: The hostname or IP address of the Kubernetes API endpoint.
·Port: The port number of the Kubernetes REST API (for example, 6443).
·Token: A bearer token for authentication against the Kubernetes REST API. Contact your Kubernetes cluster administrator to obtain a valid token if you do not already have one.
In addition, ensure the following requirements are met:
4.SSL Certificates (if applicable): If your cluster uses SSL/TLS for secure communication, ensure you have the necessary certificates. In some environments, you may need to request these from the administrator, or determine whether certificate validation should be disabled (only recommended for development environments).
5.API Permissions: Ensure that the token used has get and list permissions on the following resources: nodes, pods, namespaces, and services. If you are unsure, verify with your administrator or request expanded permissions if required.
