Kubernetes Cluster Configurations
This tutorial explains how to customize Kubernetes cluster configurations in config-sample.yaml (needed for Multi-node Installation) when you use KubeKey to provision a cluster. You can refer to the following section to understand each parameter.
######################### Kubernetes #########################
kubernetes:
version: v1.17.9 # The default k8s version is v1.17.9; you can specify 1.15.2, v1.16.13 or v1.18.6 based on your needs.
imageRepo: kubesphere # DockerHub Repo
clusterName: cluster.local # Kubernetes Cluster Name
masqueradeAll: false # masqueradeAll tells kube-proxy to SNAT everything if using the pure iptables proxy mode. [Default: false]
maxPods: 110 # maxPods is the number of pods that can run on this Kubelet. [Default: 110]
nodeCidrMaskSize: 24 # Internal network node size allocation. This is the size allocated to each node in your network. [Default: 24]
proxyMode: ipvs # The mode specifies which proxy mode to use. [Default: ipvs]
network:
plugin: calico # Calico by default. KubeSphere Network Policy is based on Calico. You can also specify Flannel based on your needs.
calico:
ipipMode: Always # IPIP Mode to use for the IPv4 POOL created at start up. If it is set to a value other than Never, vxlanMode should be set to "Never". [Always | CrossSubnet | Never] [Default: Always]
vxlanMode: Never # VXLAN Mode to use for the IPv4 POOL created at start up. If it is set to a value other than Never, ipipMode should be set to "Never". [Always | CrossSubnet | Never] [Default: Never]
vethMTU: 1440 # The maximum transmission unit (MTU) setting determines the largest packet size that can be transmitted through your network. [Default: 1440]
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.
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.
registry:
registryMirrors: [] # For users who need to speed up downloads.
insecureRegistries: [] # Set an address of insecure image registry. See https://docs.docker.com/registry/insecure/
privateRegistry: "" # Configure a private image registry for air-gapped installation (for example, docker local registry or Harbor).
addons: [] # You can specify any add-ons with one or more Helm Charts or YAML files in this field (for example, CSI plugins or cloud provider plugins).
