K8s cluster.

In Kubernetes, Services are an abstract way to expose an application running on a set of Pods. Services can have a cluster-scoped virtual IP address (using a Service of type: ClusterIP). Clients can connect using that virtual IP address, and Kubernetes then load-balances traffic to that Service across the different …

The Cluster API brings declarative, Kubernetes-style APIs to cluster creation, configuration and management. The API itself is shared across multiple cloud providers allowing for true AWS hybrid deployments of Kubernetes. It is built atop the lessons learned from previous cluster managers such as kops and kubicorn.

Step 4: Join new Kubernetes Worker Node a Cluster. The kubeadm join command is used to bootstrap a Kubernetes worker node or an additional control plane node, and join it to the cluster. The command syntax for joining a worker node to cluster is: kubeadm join [api-server-endpoint] [flags] The common flags required are:There are 2 different K8s clusters. Microservice B is deployed on both the clusters. Now if a Microservice A calls Microservice B and B’s pods are not available in cluster 1, then the call should go to B of cluster 2. I could have imagined to implement this functionality by using Netflix OSS but here I am not using it.Prometheus will use metrics provided by cAdvisor via kubelet service (runs on each node of Kubernetes cluster by default) and via kube-apiserver service only.
