and cannot be associated with replicationcontroller, deployment, or Daemonset. And Kubelet could not perform a health check on them. Static pods are always created by Kubelet and always run on the node where Kubelet resides. There are two ways to create a static pod: Configuration file or HTTP Mode 1) configuration file First, you need to set the Kubelet startup parameter "--config", specify the directory where the kubelet needs to be monitored, kube

is responsible for launching the container application, which also monitors the health of the container and restarts if a crash is generated based on a restart policy. But in order to publish the application externally, Kubernetes needs an explicitly created service object. Rancher gets the workload claims through a user-friendly interaction and creates all the required kubernetes structures in the backgro

Guide:Kubernetes a ride on the dust to open, then the enterprise should start to kubernetes migration? Under what circumstances do you really accept it? Some of the technology frontier companies first-step practice is probably the most persuasive and reference value. This article is a good reference.1Kubernetes now rage, it is part of a massive cloud-native movement. All major cloud providers use it as a solution for deploying cloud-native application

The Kubernetes network model is made up of four parts from inside to outside: The network where the pod interior container resides The network where the pod resides Network for communication between pod and service Network of communication between outside and service It is recommended that you understand the network model of Docker before reading this article. Refer to the author's first two articles [

Kubernetes has developed a Elasticsearch add-on to enable log management of the cluster. This is a combination of Elasticsearch, FLUENTD and Kibana. Elasticsearch is a search engine that is responsible for storing logs and providing query interfaces; Fluentd is responsible for collecting logs from Kubernetes and sending Elasticsearch;kibana a Web GUI that users can browse and search for stored in Logs in th

What is 1.1 kubernetes?First, it is a new, container-based, distributed architecture leading solution. is an open source version of Google's Borg (large-scale cluster management system).Second, if the system design follows the Kubernetes design idea, then the traditional system architecture and business does not have much to do with the underlying code or function modules (such as load balancing, service se

main components. The first is a pod that runs as part of a replication controller with a single copy. It runs the AOC dashboard and data collection platform. The second component is the daemonset of the AOC collector. It tells Kubernetes to run a pod with a collector container on all nodes of the environment. These collectors are configured to send information to the AOC pod.Generate trafficWe will use mor

Concept GroomingIn order to solve the above-mentioned problem, Kubernetes does not need to find a way, after all, is the network security level of the problem, every service will encounter problems, the industry has a mature solution to solve. Here we look at industry scenarios and related concepts. Symmetric encryption/Asymmetric encryptionThese two concepts belong to cryptography, which is not easy to understand for the students who have n

multiple labels, associating objects through labels. higher-level abstraction based on basic objects: nreplicaset Next Generation Replicationcontroller. Ensure the number of pod replicas specified at any given time and provide functionality such as declarative updates. The only difference between RC and RS is that lableselector support is different, RS supports a new collection based label, and RC only supports an equation based label. NDeployment Deployment is a higher-level API object that m

This article describes the use of Node-exporter, Prometheus, Grafana to monitor the cluster in a k8s cluster.Its implementation principle is somewhat similar to elk, EFK combination. The Node-exporter component collects the metrics monitoring data on the node and pushes the data to Prometheus, Prometheus is responsible for storing the data, and grafana the data to the user in a graphical form on the Web page. Before you begin, it is necessary to understand what the next Prometheus is. Prometheu
