Kubernetes cluster configuration notes This article describes how to configure a Kubernetes cluster. A kubernetes cluster consists of a master node and a slave node. Run the following services on the Master node:Etcd (the etcd service can also be run independently, not necessarily on the Master node)Kube-apiserverKube-

policies are firewall rules that specify the types of data that are allowed to flow in and out. If required, kubernetes can block all traffic that is not explicitly allowed. This paper introduces the network policy of k8s and tests the network performance. Network PolicyK8s network policies are applied to pod groups identified by common tags. You can then use tags to emulate traditional segmented networks, which are often used to isolate layers

the concepts in Kubernetes node, Pod, Replication Controller, service, etc. can be considered as a "resource object", almost all resource objects can be implemented through the Kubectl tool (API call) to perform an increase, delete, change, Check the operation and save it in ETCD for persistent storage. From this point of view, Kubernetes is actually a highly au

containers, making deployment and management more flexible. 　　　　　　 　　　　　　 A pod can contain a container or multiple related containers. 2) Replication ControllerThe Replication Controller manages a copy of the pod to ensure that a specified number of pod copies exist in the cluster. If the number of replicas in the cluster is greater than the specified number, the number of extra containers that are outside the specified number is stopped, and conversely, containers with fewer than a specified

Ubernetes is the King of container orchestration and scheduling, it beats the competitors Docker swarm and Apache Mesos, opens the bright future, microservices can be self-repairing, can be automatically expanded, can cross zone, Region even across cloud providers for federate. In this new era of cloud-native applications, it is becoming increasingly important to have a simple insight into how services interact with each other, which can be different from a haystack-wide search for a specific ca

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 v

. When specifying a plug-in in kubernetes, you need to specify the plug-in parameters in the Kubelet service startup parameters:... --network-plugin=cni --cni-conf-dir=/etc/cni/net.d \ # 此目录下的配置文件要符合CNI规范。 --cni-bin-dir=/opt/kubernetes/bin/cni ...There are several open source projects that support deployment to kubernetes
