kubernetes Introduction Kubernetes is a container cluster management system that Google Open-source in June 2014, using the Go language development, Kubernetes also called k8s. K8s is a Borg container cluster management system inside Google, Borg has been operating on Goog

The previous article describes the use of Traefik for service publishing in Kubernetes 1.5.2 cluster environments. Traefik is deployed in Daemonset mode, and the connection Api-server is the HTTP protocol, and RBAC is not configured. This article describes the deployment of Traefik for service publishing in the K8s 1.9 release using the deployment method.Before you begin, you need to know what RBAC is. RBAC

Kubernetes is a distributed cluster of Google's Docker based, with the following main components　　ETCD: High-availability storage sharing configuration and service discovery, used as a companion to flannel on Minion machines, to enable Docker running on each minion to have different IP segments The ultimate goal is to make the Docker Containner running on different minion have an IP address that is not the

Kubernetes can automatically run multiple copies of Odoo services, so it 's very well suited to make a highly available Odoo deployment, in this case,Odoo The service runs in the kubernetes cluster, while the PostgreSQL database runs in another Cluster host host Network on the other hostInstall

#Galera集群特点 No delay between clusters, synchronous replication. While Master-slave master-slave asynchronous replication, there is a delay. Active-active Multi-master, the cluster internal server is written at the same time, must wait for all the databases in the cluster to complete the data write, the feedback is complete, so there is no data loss situation. The

container sizes, and so on. Here are some interesting information and controls1. With Kubectl get deploy, you can view some details about each deployment2. Kubectl get RS for each deployment-related replication set (replicas)3. Use the KUBECTL scale command to specify how many containers to run for an appKubectl scale--replicas=3 rs/mvcapp-1456147153Note: In fact, when Kubectl run, you can specify the number of containers to run at the same time, and if you prefer, you can set it to Autoscale (

This article will introduce the creation and use of Kube-ui (also called dashboard) on the basis of the previous article. This thing is essentially the WebUI connection Master API interface, through the API to obtain information about the k8s cluster, and then on the web display, for the user is more friendly, the actual use is not very large.One, download the image file and incorporate the unified management of the local warehouse# docker pull docker

The security of the cluster mainly considers the following aspects: Isolation of the container from the host; Limiting the ability of containers to adversely affect infrastructure and other containers; The principle of least privilege--to reasonably restrict the permissions of all components, to ensure that the component only performs its mandated behavior, limiting the scope of the permissions it can achieve by restricting the ability of

Original intentionSince the advent of kubernetes (k8s), the installation of complex, difficult to deploy has been the industry to spit groove, but also a lot of beginners to block outside the door. While there are also official standalone deployment options for getting Started: Minikube, and the kubeadm used to build the cluster, the domestic green network environment makes the official program extremely co

This is a creation in Article, where the information may have evolved or changed. Kubernetes cluster has been set up, has been running very stable. Previous concerns have focused more on installation, configuration, and component debugging, and some of the minutiae has been overlooked. The settings for the time zone in the pod are one of them. I'm going to try to solve this problem today. First, the problem
