(1)、centos8分配IP地址

nmcli c up ens33

(2)、下载docker-ce的repo

curl https://download.docker.com/linux/centos/docker-ce.repo -o /etc/yum.repos.d/docker-ce.repo

(3) 、安装依赖

yum install https://download.docker.com/linux/fedora/30/x86_64/stable/Packages/containerd.io-1.2.6-3.3.fc30.x86_64.rpm

(4)、安装docker-ce

yum install docker-ce

(5)、启动docker

systemctl start docker

(6)、关闭系统的Swap

swapoff -a

(7)、Kubernetes yum源配置：

vim /etc/yum.repos.d/kubernetes.repo

[kubernetes]

name=Kubernetes Repo

baseurl=https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64/

gpgcheck=0

enabled=1

(8)、master节点安装kubelet kubeadm docker-ce kubectl node节点安装kubelet kubeadm docker-ce

master #yum install -y docker-ce kubelet kubeadm kubectl

node #yum install -y docker-ce kubelet kubeadm

all node#systemctl enable docker && systemctl start docker

all node#systemctl enable kubelet

(9)、下载k8s.gcr.io

docker pull mirrorgooglecontainers/kube-apiserver:v1.15.0
docker pull mirrorgooglecontainers/kube-controller-manager:v1.15.0
docker pull mirrorgooglecontainers/kube-scheduler:v1.15.0
docker pull mirrorgooglecontainers/kube-proxy:v1.15.0
docker pull mirrorgooglecontainers/pause:3.1
docker pull mirrorgooglecontainers/etcd:3.2.24
docker pull coredns/coredns:1.2.6
docker tag docker.io/mirrorgooglecontainers/kube-apiserver:v1.15.0 k8s.gcr.io/kube-apiserver:v1.15.0
docker tag docker.io/mirrorgooglecontainers/kube-controller-manager:v1.15.0 k8s.gcr.io/kube-controller-manager:v1.15.0
docker tag docker.io/mirrorgooglecontainers/kube-scheduler:v1.15.0 k8s.gcr.io/kube-scheduler:v1.15.0
docker tag docker.io/mirrorgooglecontainers/kube-proxy:v1.15.0 k8s.gcr.io/kube-proxy:v1.15.0
docker tag docker.io/mirrorgooglecontainers/pause:3.1 k8s.gcr.io/pause:3.1
docker tag docker.io/mirrorgooglecontainers/etcd:3.2.24 k8s.gcr.io/etcd:3.2.24
docker tag docker.io/coredns/coredns:1.2.6 k8s.gcr.io/coredns:1.2.6
