This command initializes a Kubernetes worker node and joins it to the cluster. Run this on any machine you wish to join an existing cluster Synopsis When joining a kubeadm initialized cluster, we need to establish bidirectional trust. This is split into discovery (having the Node trust the Kubernetes Control Plane) and TLS bootstrap (having the Kubernetes Control Plane trust the Node). There are 2 main schemes for discovery. The first is to use a shared token along with the IP address of the API server.

The cluster audits the activities generated by users, by applications that use the Kubernetes API, and by the control plane itself. Auditing allows cluster administrators to answer the following questions: what happened? when did it happen? who initiated it? on what did it happen? where was it observed? from where was it initiated?

Set up monitoring and logging to troubleshoot a cluster, or debug a containerized application.
