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 clusterK

MASTER role : As the host node of the cluster, run a collection of three programs in the cluster, respectively:

the trend of the community, for the next version of the parameter configuration policy: 1. Turn off unsecured ports, all traffic over secure ports, 2. Dynamically create bootstrpping Auth token, bootstrpping TLS Cert, auto approve certificate, certificate rotation, etc. 3. Configure the Kublet, kube-proxy parameters in the configuration file, rather than the command line, to prepare for subsequent dynamic modification of the component configuration;

This is a creation in Article, where the information may have evolved or changed. Hello everyone, I am Xu Chao, engaged in Kubernetes development has been more than two years. Today, I talk about Client-go repository from a developer's point of view and how to build a Controller with Client-go. At the same time, we also give you a talk about the development process encountered in the pit, I hope everyone in the development of the time can be around

containers work? A: We are small, no performance bottleneck, 1.2 (specifically not clear) after the kube-proxy is pure iptables implementation, not so bad bar, the industry is also useful haproxy, such as the replacement, the individual felt no need. Specific container fixed IP we did not implement, we do not have this scenario. You can compromise, give a nodeport, fixed IP I personally feel as little as possible to use as well. Q: Can th

master node's own IP address, cluster_ip_subnet for the entire cluster subnet range, For example, 192.168.0.0/16, while Master_switch_subnet is the subnet range that the pod on the master node can allocate, such as 192.168.1.0/24SOURCE Link: https://github.com/YaoZengzeng/scripts/blob/master/ovn-k8s-master.sh4, at first I was using KUBEADM to build k8s cluster, but when the API server through http://127.0.0.1:8080 to find that the port is not open, it may be kubeadm by default is not open the p
