OpenStack Heat autoscaling
I. BACKGROUND
OpenStack's heat is a component that was added after the H version, designed to create a business process that makes it easier to manage a cluster. The virtual machines within the cluster can serve as a whole and serve the customers uniformly. Heat defines functionality as a resource and uses components such as nova,neutron,ceilometer in heat, which can be viewed as resources, described by template files, tem
At this point the browser will prompt you: certificate issues. Ignore it (because Apiserver uses a self-signed private certificate, the browser can not verify the Apiserver server.crt), continue to access the browser popup login dialog box, let you enter the user name and password, here we enter apiserver- Basic-auth-file user name and password, you can successfully login to Apiserver and see the following on the browser page:

The Cluster Lifecycle layer adds self-hosted functionality to Kubeadm, which means that Kubernetes can be run on Kubernetes, which is bootstrap. Bootstrap is considered to be a system of "elegance" of a embodiment, in fact, Kubernetes in the early attempt to bootstrap, now Kubeadm directly add this feature, is undoubtedly a step closer. In addition, the KUBEADM c

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 [
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
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.

What is a container?Kubernetes is a container management platform. It is conceivable that we need containers to manage them. But what is a container? The best answers to the official Docker documentation are:
A container image is a lightweight, standalone, executable package that contains everything that can be run: Code, runtime, System tools, system libraries, settings. For Linux and Windows-based applications, containerized software can ru
