The role of Kubernetes Scheduler is to bind controller manager to a new pod according to a specific scheduling algorithm and scheduling policy to a suitable node in the cluster, and to write the binding information to the ETCD.I. Deployment OF SchedulerThe following generates the Kube-scheduler Kubeconfig file, as follows:cd/etc/kubernetesexport kube_apiserver="https://192.168.15.200:6443"Configure clusterKubectl config set---certificate-authority=/et

Brief Description:Using the Rke tool, on the 192.168.3.161 machine, create a kubernetes cluster with two nodes (192.168.3.162 and 192.168.3.163). Rke automatically creates KUBE_CONFIG_CLUSTER.YML configuration files in the/home/user directory.On another server (192.168.3.160), run the Rancher Server 2.0 container. After running, use the https://192.168.3.160 address to access Rancher Server 2.0 preview. (Note: No longer the previous 8080 port)In the R

Containerized technology (containerization).You may have a lot of doubts: what exactly is a container and how does it work? What does Docker and kubernetes mean, and what is the use of Google Container engine and managed VMS? How are they related, and how can we build a powerful service through containers and make them available in a large-scale cluster of production environments? How can you get business value by using this technology? Well, we don't

Services deployed by users on Kubernetes typically run on private networks, and pod and service provide parameters such as Hostport,nodeport to expose these service ports to K8S nodes for user access. There are obvious drawbacks to this approach:1) Easy to occupy excessive host port;2) service ports exposed to multiple hosts increasing the difficulty of firewalls and security configuration3) The default hostport,nodeport mode does not function as load

Brief introductionKubernetes is an open source, containerized application for managing multiple hosts on a cloud platform, with the goal of making deploying containerized applications simple and efficient, Kuernetes provides a mechanism for application deployment, planning, updating, and maintenance.In Kubernetes, all containers are run in pods, and one pod can host one or more related containers. Each pod system created by the user automatically choo
