Instance, and the compute node itself is working properly. If the compute node fails, OpenStack cannot communicate with the node's nova-compute, and all instance running on it will be affected. At this point, the Instance can only be rebuilt on other normal nodes through the evacuate operation.EvacuateRebuilds Instance on other compute nodes using the Instance image file on the shared storage. So planning for shared storage ahead of time is key.SectionHere, we've learned about the OpenStack Nov

So planning for shared storage ahead of time is key.SectionHere, we've learned about the OpenStack Nova architecture, discussed key components such as Nova Api,scheduler,compute, and analyzed the Nova operations in detail, and finally summed up the purpose and usage scenarios for these operations using a single graph.Nova is the most important project in OpenStack, at the cen

Objective In order to ensure a weekly progress, and because the new version of Vitamio has not been released, decided to postpone the local playback of some features (screenshots, video time, size, etc.), skip directly write the section of the online play part. As you can see from Vitamio's introduction, it supports a variety of network protocols such as HTTP, m3u8, and this chapter will write examples of playing Youku videos. Series

Play with Qt (1) and play with Qt ( Recently I have been reading some things about the game engine. I have several small game ideas. In fact, the implementation is quite troublesome. I want to find a game engine to see if it can be coded. A lot of 2D engines were found after the revolution, among which the domestic cocos2dx seems to be widely used, but many peopl

learned how to pass configuration information to the Pod. Use Secret If the information requires encryption, or use Configmap if it is a generic configuration information. Secret and Configmap support four methods of definition. Pod can choose Volume mode or environment variable mode when using them, but only the Volume mode supports dynamic update. In the next section, we will begin to learn about the Helm-kubernetes package Manager. Books: 1. "

With the first two articles, we already know the basics and tips for making animations, and here are 5 very useful points of knowledge to explore the PS timeline more deeply. The end of this article is accompanied by a PSD, which can be downloaded to analyze animation techniques. 　　1, using smart objects skillfully With tips, the PS timeline can do more complex animations, and these animations are impleme

Policy: busybox Pod has no access Service. if Pod added label access: "true" can access the app, but Ping has been banned. The cluster node has no access to the Service, nor does it Ping the replica Pod. The Service cannot be accessed outside the cluster (192.168.56.1). If you want to have the cluster nodes and the outside of the cluster (192.168.56.1) also have access to the application, you can make the following modifications to Network Policy:Apply the new Network P
