Overview
Updated on 2022-09-08 GMT+08:00
Kubernetes is an open-source container orchestration system for automating containerized application deployment, scaling, and management across hosts in clouds.
For application developers, Kubernetes can be regarded as a cluster operating system. Kubernetes provides functions such as service discovery, scaling, load balancing, self-healing, and even leader election, freeing developers from infrastructure-related configurations.
You can use CCE, a hosted Kubernetes service provided by HUAWEI CLOUD, by means of the . Before using CCE, you are advised to learn about the following Kubernetes concepts.
Containers and Kubernetes
Pods, Labels, and Namespaces
Pod Orchestration and Scheduling
Kubernetes Networking
Persistent Storage
Authentication and Authorization
Auto Scaling
