together or independently, one node at a time as per your requirements. • Shared platform for heterogeneous workloads The platform can support a broad range of operating environments simultaneously such platforms with a unified underlying infrastructure platform and management. It can also support heterogeneous workloads with varying requirements on a flexible shared infrastructure platform and modernize FQDN or the IP address of the Kubernetes API server or Load Balancer. • Port: Port to use for communication when not using the default port, 443 Note: The use of any port other than 443 or 6443 requires

Logically, it makes sense to co-locate tightly coupled components as close to enable easier network communication and shared storage usage. Kubernetes enables co-locating related containers through pods. which are not yet assigned to nodes and schedules them. • Rancher-kubernetes-agent manages the communication between Rancher and the Kubernetes cluster • Rancher-ingress-controller will leverage the name: mysecret key: username Service accounts are another way to manage communication between services or pods, and are typically used to access an API server to derive the share

kubelet's ability to automatically create self-signed certs. No CA cert is saved to verify the communication between kube-apiserver and kubelet . Mitigation Make sure nodes with role:controlplane Notes RKE does not set these options and uses the kubelet's self generated certificates for TLS communication. These files are located in the default directory ( /var/lib/kubelet/pki ). Audit ( --tls-cert-file

GCP. On top of this, there is an additional fee for the connectivity service that provides communication among on- premises and cloud. 3.1.2 Intuitive UI • SUSE Rancher: 4 • OpenShift: 3 • Copyright © SUSE 2022 21 3.2.1.2 OpenShift OpenShift runs an internal OAuth server and proxies communication to multiple backend providers. It maintains compatibility with providers based on LDAP, Keystone

nodes shown can be VMs or bare metal servers. Figure 6: Single Cluster CN2 on Rancher RKE2 All communication between nodes in the cluster and between nodes and external sites takes place over the single verify that your CN2 installation is working properly. The checks test for status, pod-to-pod communication, API server reachability, and other basic functions. You run postflight checks after installing
