Kubernetes 集群配置

本教程介绍使用 KubeKey 安装集群时，如何在 config-example.yaml 文件中配置 Kubernetes 集群参数（多节点安装时需要此文件）。文件中每个参数的说明如下：

  1. ######################### Kubernetes #########################
  3. kubernetes:
  4.     version: v1.17.9 # The default k8s version is v1.17.9, you can specify 1.15.2, v1.16.13, v1.18.6 as you want
  5.     imageRepo: kubesphere  # DockerHub Repo
  6.     clusterName: cluster.local # Kubernetes Cluster Name
  7.     masqueradeAll: false  # masqueradeAll tells kube-proxy to SNAT everything if using the pure iptables proxy mode. [Default: false]
  8.     maxPods: 110  # maxPods is the number of pods that can run on this Kubelet. [Default: 110]
  9.     nodeCidrMaskSize: 24  # internal network node size allocation. This is the size allocated to each node on your network. [Default: 24]
  10.     proxyMode: ipvs  # mode specifies which proxy mode to use. [Default: ipvs]
  11.   network:
  12.     plugin: calico   # Calico by default, KubeSphere Network Policy is based on Calico. You can also specify Flannel as you want
  13.     calico:
  14.       ipipMode: Always  # IPIP Mode to use for the IPv4 POOL created at start up. If set to a value other than Never, vxlanMode should be set to "Never". [Always | CrossSubnet | Never] [Default: Always]
  15.       vxlanMode: Never  # VXLAN Mode to use for the IPv4 POOL created at start up. If set to a value other than Never, ipipMode should be set to "Never". [Always | CrossSubnet | Never] [Default: Never]
  16.       vethMTU: 1440  # The maximum transmission unit (MTU) setting determines the largest packet size that can be transmitted through your network. [Default: 1440]
  17.     kubePodsCIDR: 10.233.64.0/18    # A valid CIDR range for Kubernetes pod subnet, it should not overlap with node subnet, and it should not overlap with Kubernetes services subnet.
  18.     kubeServiceCIDR: 10.233.0.0/18  # A valid CIDR range for Kubernetes services, it should not overlap with node subnet, and it should not overlap with Kubernetes pod subnet
  19.   registry:
  20.     registryMirrors: []   # For users who need to accelerate image download speed
  21.     insecureRegistries: [] # Configure an address of Insecure image Registry, see https://docs.docker.com/registry/insecure/
  22.     privateRegistry: ""   # Configure a private image registry for air-gapped installation (e.g. docker local registry or Harbor)
  23.   addons: []  # You can specify any add-ons with one or more Helm Charts or YAML files in this field, e.g. CSI plugins or cloud provider plugins.
