9.安装Calico
9.1以下步骤只在master01操作
9.1.1更改calico网段
代码语言：shell复制# vim calico.yaml
vim calico-ipv6.yaml
# calico-config ConfigMap处
"ipam": {
"type": "calico-ipam",
"assign_ipv4": "true",
"assign_ipv6": "true"
},
- name: IP
value: "autodetect"
- name: IP6
value: "autodetect"
- name: CALICO_IPV4POOL_CIDR
value: "172.16.0.0/16"
- name: CALICO_IPV6POOL_CIDR
value: "fc00::/48"
- name: FELIX_IPV6SUPPORT
value: "true"
# kubectl apply -f calico.yaml
kubectl apply -f calico-ipv6.yaml 9.1.2查看容器状态
代码语言：shell复制[root@k8s-master01 ~]# kubectl get pod -A

[root@k8s-master01 ~]# 10.安装CoreDNS
10.1以下步骤只在master01操作
10.1.1修改文件
代码语言：shell复制cd coredns/
sed -i "s#10.96.0.10#10.96.0.10#g" coredns.yaml
cat coredns.yaml | grep clusterIP:
clusterIP: 10.96.0.10 10.1.2安装
代码语言：shell复制kubectl create -f coredns.yaml
serviceaccount/coredns created
clusterrole.rbac.authorization.k8s.io/system:coredns created
clusterrolebinding.rbac.authorization.k8s.io/system:coredns created
configmap/coredns created
deployment.apps/coredns created
service/kube-dns created11.安装Metrics Server
11.1以下步骤只在master01操作
11.1.1安装Metrics-server
在新版的Kubernetes中系统资源的采集均使用Metrics-server，可以通过Metrics采集节点和Pod的内存、磁盘、CPU和网络的使用率
代码语言：shell复制# 安装metrics server
cd metrics-server/
kubectl apply -f metrics-server.yaml 11.1.2稍等片刻查看状态
代码语言：shell复制kubectl top node
