In general, the MySQL container is important for two parts, one for storing data and the other for configuration file MY.CNF.As previously tested, the storage data can be decoupled with the PV PVC implementation and the separation of the containers.The configuration file can also be decoupled fro

an example:The following pod consists of two containers: file puller and Web serverFile puller periodically pulls the latest files from the external Content manager and stores them in the shared volume. The Web Serverv reads the file from volume and responds to consumer requests.The two containers are tightly coordinated, together they provide the latest data for consumer, and they share data through volume. So it's appropriate to put it in a pod.One more example: do you need to put Tomcat and

Kubernetes Basic Concept Summary

the service's Yaml file as App:my-web, the service will Pod-->metadata-->labeks label as the app: The My-web pod acts as the backend for the distribution request. When the pod changes (increase, decrease, rebuild, etc.), the service is updated in a timely manner. As a result, the service can serve as the access portal for the pod, acting as a proxy server, and for visitors to access through the service without having to directly perceive the pod.It is important to note that the fixed IP assigne

What is Kubernetes?

" and "Services". The purpose of Kubernetes is to support as many loads as possible, including stateful, stateless, data-processing loads, so long as the application can run in a container, it can run well in kubernetes. Kubernetes does not provide middleware (such as message bus), data processing frameworks (such as Spark), databases (such as

databases, caches and so on. With this scheme, the container can be connected horizontally and can be accessed vertically. The external connection container can be connected directly through the container IP address, or it can be accessed through load balancing. The container can also directly access virtual, physical machine resources, as well as MySQL and other component Services outside the Leengine system. We have written our own and CNICTL mana
