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.
A cluster network can be divided into three network types:
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. You cannot change the container network model after the cluster is created. Plan the container network model properly in advance.
You are advised to learn about the cluster network and container network models before creating a cluster. For details, see Container Network Models.
When you create a cluster on CCE, you can have one or three master nodes. Three master nodes will be deployed in a cluster for HA.
The master node specifications decide the number of nodes that can be managed by a cluster. You can select the cluster management scale, for example, 50 or 200 nodes.
