straightforward (running Kubectl rollout undo Deployment/some-deployment,kubernetes will restore the previous "snapshot"), but for this feature to take effect, Your meta-project should contain information about this snapshot. But the more complex delivery rollback algorithms are daunting, although they are sometimes required.Here's what you can do to trigger the rollback mechanism:High percentage of application errors after publishingSignals from key

Serves as the server for the Kubernetes API, providing API services for nodes within the cluster as well as KUBECTL tools.

connected and uses multiple microservices containers to create stable application services.Rich features, simple tools, and powerful APIs make containers and orchestration a favorite for DevOps teams. DevOps engineers integrate them into continuous integration (CI) and continuous delivery (CD) workflows.This article explores the issues you encounter when trying to run and orchestrate a MongoDB container, and describes how to overcome these problems.T
I. Background INTRODUCTION
As we all know, due to the domestic network reasons, in the construction of kubernetes environment, often encountered the need for the mirror can not find the situation.
After all, it is not a good idea to pick up rubbish in Dockerhub, this article teaches everyone to build their own mirror warehouse in Dockerhub.
Request: Have GitHub account number, have dockerhub account number, do not register.

frameworks are Kubernetes, Mesos, Docker Swarm. Kubernetes is the most mature and most scalable solution on the market, occupying the largest market share. The above three orchestration frameworks are open source, and users only pay for technical support services.Between the kubernetes and the Docker container, not Apple and Apple, you can't compare business pro

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
things. You can use it to expand the kubernetes according to your hobby. such as data collection, deployment engines, or a simple cleanup application.Learn this go client and use it in Kubernetes, which is the biggest recommendation I give to every user who uses Kubernetes.Original link:

How to build a Kubernetes (k8s) Environment
The official version of k8s is updated too quickly. Many articles on the Internet are outdated and many tools and interfaces have changed. the official website does not have a good understanding. Here we only record the process of setting up the k8s environment and will not talk about many k8s concepts. Therefore, we recommend that you first understand various con

host. The data is written to Etcd to make it visible to other components and operators of the network.
Orchestrator plug-in (optional)Unlike Felix without a separate orchestrator plugin, each major cloud orchestration platform (such as Kubernetes) has a separate plugin. These plug-ins bind calico more tightly to the coordinator, allowing the user to manage the Calico network just like the network tools
Detailed guide for manual installation and deployment of Kubernetes on Ubuntu, ubuntukubernetes
Background
Two Ubuntu16.04 servers: 192.168.56.160 and 192.168.56.161.
Kubernetes version: 1.5.5
Docker version: 1.12.6
Etcd version: 2.2.1
Flannel version: 0.5.6
Among them, 160 servers are both master nodes of Kubernetes and node nodes. 161 servers are only node node
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 more tools
