kubernetes1.17.2离线安装

环境：centos7、三个主节点的kubernetes

1、关闭selinux、firewalld、swap
2、修改主机名称 hostnamectl set-hostname master1
3、更新系统时间 timedatectl set-timezone Asia/Shanghai

4、上传文件：链接: https://pan.baidu.com/s/1EWV8XwEH32TQ6D2qXnyA_g 提取码: 4jwj
kube1.17.2.tar.gz
sealos

5、配置sealos工具
chmod +x sealos && mv sealos /usr/bin

6、配置hosts
cat <>/etc/hosts
172.21.210.4 master1
172.21.210.5 master2
172.21.210.6 master3
172.21.210.7 node1
EOF

7、安装k8s集群
sealos init --master 172.21.210.4 \
--master 172.21.210.5 \
--master 172.21.210.6 \
--node 172.21.210.7 \
--user root \
--passwd server-passwd \  #替换为服务器密码
--version v1.17.2 \
--pkg-url /root/kube1.17.2.tar.gz

8、添加新节点

kubeadm token create --print-join-command   #获取token
kubeadm join apiserver.cluster.local:6443 --token uqdcs4.svi229q32vvh098d     --discovery-token-ca-cert-hash sha256:460de3edc9bfdc49226249937ae0db4d51d731dffb8859d00a9fb0a396dfefa2 
scp -r kube root@172.19.163.142:/root/     #复制安装包到新节点

cd kube/shell && chmod u+x init.sh && ./init.sh   #新节点进行初始
sed -i "s/127.0.0.1/172.21.210.20/g" /etc/docker/daemon.json   #配置自己的harbor地址
systemctl restart docker
docker login 172.21.210.20   #登录harbor
admin

echo "10.103.97.2 apiserver.cluster.local" >> /etc/hosts   # using vip 这儿不变
kubeadm join 10.103.97.2:6443 --token uqdcs4.svi229q32vvh098d \ #token为上面获取的token
    --master 172.21.210.4:6443 \
    --master 172.21.210.5:6443 \
    --master 172.21.210.6:6443 \
    --discovery-token-ca-cert-hash sha256:460de3edc9bfdc49226249937ae0db4d51d731dffb8859d00a9fb0a396dfefa2

9、进行验证

[root@master1 ~]# kubectl get nodes
NAME                 STATUS   ROLES    AGE   VERSION
master1              Ready    master   30h   v1.17.2
master2              Ready    master   30h   v1.17.2
master3              Ready    master   30h   v1.17.2
node1                Ready       30h   v1.17.2
