kubeadm 部署k8s-1.15.0

部署环境

master01: 192.168.48.101
node01: 192.168.48.201
node02: 192.168.48.202

所有节点都要写入hosts

[root@master01 ~]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.48.101 master01
192.168.48.201 node01
192.168.48.202 node02

部署准备

所有节点准备

以下都要在所有节点上执行

准备docker yum仓库
准备k8s yum仓库
准备 epel yum仓库

docker yum

配置docker的yum库

cd /etc/yum.repos.d/ 

wget https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

k8s yum

配置k8s的yum库

cd /etc/yum.repos.d/ 

cat << EOF > kubernetes.repo
[kubernetes]
name=kubernetes
baseurl=https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64/
gpgcheck=0
enabled=1
EOF

epel yum

配置epel的yum库

cat > /etc/yum.repos.d/epel.repo << EOF
