[Summary Post] Kubernetes Basic Knowledge Directory

Kubernetes is an open source, used to manage containerized applications on multiple hosts in the cloud platform. The goal of Kubernetes is to make the deployment of containerized applications simple and efficient. Kubernetes provides application deployment, planning, update, and maintenance. A mechanism of

A core feature of Kubernetes is the ability to independently manage containers to ensure that the containers in the cloud platform are running in accordance with the user's desired state (for example, if the user wants to keep apache running, the user does not need to care about how to do it, Kubernetes will automatically monitor it, and then go Restart, create new, in short, let apache always provide services), the administrator can load a micro service, let the planner find a suitable location, at the same time, Kubernetes also system upgrade tools and human aspects, so that users can easily deploy their own application.

You can use the Kubernetes hosting service provided by Cloud Container Engine through the CCE console, Kubectl command line, and Kubernetes API. Before using the cloud container engine, you can first understand the following Kubernetes related concepts, so that you can use all the functions of the cloud container engine more completely.
