On the left is my personal, if you need further communication, please add. 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

Kube-dns compositionKube-dns can solve the service discovery problem, k8s registers the service name as a domain name into Kube-dns, and can access the services it provides through the name of the service.Kube-dns of four components: ETCD, which is used to save DNS rules. kube2sky, the role is to write DNS rules. skydns, provides DNS resolution services. healthz, provides health check function. whichSkydns is an open-source framework for service discovery, built on ETCD. The function is

Mesos and Kuberneteshttp://dockone.io/article/956 I firmly believe that their use will grow faster in the next year, so it is time to review the summary and prepare for 2016 years. I would like to discuss the current situation of Mesos and kubernetes and enumerate the strengths and weaknesses that will allow you to understand the concept of cluster manager.Mesos and KubernetesBefore I start, I'd like to take the time to roughly compare Mesos and

Colleagues who have studied kubernetes know that kubernetes if you need to enable TLS authentication, making a certificate is an essential step. However, many people encounter a lot of trouble in making certificates. Today is the main record of how I made my certificate during the deployment of Kubernetes. Throughout the process, the startup parameters for each c

Tags: WordPress MySQL KubernetesWordPress is the main platform for editing and publishing Web content. In this tutorial, I'll step through how to use kubernetes to build a high availability (HA) WordPress deployment.WordPress consists of two main components: a wordpress PHP server and a database for storing user information, posts, and website data. We need to make these two components in the entire application both highly available and fault tolerant

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

There are several ways to install the Kubernetes cluster, the KUBEADM approach is described earlier, and the manual installation method is described in this article.The installation environment has 3 VMS on Azure:HKUBE01:10.0. 1.4 HKUBE02: 10.0. 1.5 Hbube03: 10.0. 1.6Where hkube01 is the master node, it will install Docker, ETCD, Kubernetes Master, flannel required components;HKUBE02 and hkube03 are worker

1. Bash Auto-refill for KUBECTL commandsThis is probably the easiest thing to do in the kubernetes process, but it's also one of the most useful. To add the auto-refill feature, if you use bash, simply execute the following command:echo"sourceIt will add an auto-complete command to your. bashrc file. So each shell window you open supports this feature. I found that auto-completion is especially useful for some long parameters, such as--all-namespaces.
