On the right is my public number "OpenStack private cloud", if interested, please pay attention.in the previous post, " Kubernetes Getting Started learning mentioned in the Katacoda experimental environment can be further familiar with the use of k8s , the specific URL is: https://www.katacoda.com/courses/kubernetes/Recently spent s

The content of this article has been validated based on k8s v1.8.8. K8s Service defines the access entry address of a server, the front-end application accesses a cluster of pod replicas behind it through this entry address, and the access requests from outside are load balanced to each container application on the back end. Between the service and the back-end pod replica cluster, the docking is done through the label selector. The function of RC is to ensure service ability and service quality

Deploy Kubernetes in Docker Kubernetes is an open-source container management framework of Google. It provides a series of functions such as host, cluster management, container deployment, high availability, and auto scaling of Docker containers; kubernetes's design goals include putting the container cluster in the desired state at any time. Therefore, a complete cluster management mechanism is established

Rancher is an open-source full-stack enterprise container management platform, the user in the rancher visual interface in a single click to complete all the container infrastructure (network, storage, load balancing, etc.) docking and deployment, to ensure that the container on any infrastructure (public and private cloud, virtual machine, The physical machine, etc.) runs seamlessly. All the work of using containers in a production environment can be done with simple, intuitive operation.?start

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

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

If you're an OPS engineer, you know that Docker is valued at more than $1 billion, and Docker is one of the most popular technology brands. Docker containers are known as the de facto standard for container runtimes, but Google's kubernetes is winning the choreography framework market. When using container technology, we often encounter the question, "will using Kubernetes hurt Docker?" ”Many people believe
