部署K8S集群
-
服务器硬件要求：三台虚拟机服务器，操作系统都为centos；
硬盘最低配置：内存2GB，CPU2核，硬盘30GB。
- 准备环境

Run "kubectl apply -f [podnetwork].yaml" with one of the options listed at: https://kubernetes.io/docs/concepts/cluster-administration/addons/ Then you can join any number of worker nodes by running the following on each as root: kubeadm join 192.168.200.110:6443 --token rhbbob.v6njal97il1vlx74 \ --discovery-token-ca-cert-hash sha256:47a6fe2b1e400310acf2a020798f22d00b43dc46d3d8e5d0eddd8865cdc5f3e9 [root@master kubelet.service.d]# 初始化之后，会输出一个join命令，先复制出来，node节点加入master会使用。 [root@master01 ~]# vim /etc/docker/daemon.json 修改配置文件，三个节点都要 { "exec-opts": ["native.cgroupdriver=systemd"] }– apiserver-advertise-address 集群通告地址
– image-repository 由于默认拉取镜像地址k8s.gcr.io国内无法访问，这里指定阿里云镜像仓库地址
– kubernetes-version K8s版本，与上面安装的一致
– service-cidr 集群内部虚拟网络，Pod统一访问入口
– pod-network-cidr Pod网络，与下面部署的CNI网络组件yaml中保持一致 -
