Cluster Overview
Kubernetes is an open-source container orchestration engine for automating deployment, scaling, and management of containerized applications.
For developers, Kubernetes is a cluster operating system. Kubernetes provides service discovery, scaling, load balancing, self-healing, and even leader election, freeing developers from infrastructure-related configurations.
Cluster Network
A cluster network can be divided into two parts:
- Container network: assigns IP addresses to containers in each pod of a cluster for communication. Currently, only Cloud Native 2.0 network model is supported.
- Service network: A Service is a Kubernetes object used to access containers. Each Service has a static IP address.
When you create a cluster, select a proper CIDR block for each network. Ensure that the CIDR blocks do not conflict with each other and have sufficient available IP addresses.
