# yum install epel-release -y
# yum install ansible -y
下载Ansible部署文件:
# git clone https://github.com/lizhenliang/ansible-install-k8s
# cd ansible-install-k8s
下载准备好软件包(包含所有涉及文件和镜像,比较大),解压到/root目录:

# tar zxf binary_pkg.tar.gz
修改hosts文件,根据规划修改对应IP和名称。
# vi hosts
...
修改group_vars/all.yml文件,修改软件包目录和证书可信任IP。
# vim group_vars/all.yml
software_dir: '/root/binary_pkg'
...
cert_hosts:
k8s:
etcd:
单Master版:
# ansible-playbook -i hosts single-master-deploy.yml -uroot -k
多Master版:
# ansible-playbook -i hosts multi-master-deploy.yml -uroot -k
# kubectl get node
NAME STATUS ROLES AGE VERSION
k8s-master Ready <none> 9h v1.20.4
k8s-node1 Ready <none> 9h v1.20.4
k8s-node2 Ready <none> 9h v1.20.4
如果安装某个阶段失败,可针对性测试.
例如:只运行部署插件
# ansible-playbook -i hosts single-master-deploy.yml -uroot -k --tags addons
1)修改hosts,添加新节点ip
# vi hosts
...
[newnode]
192.168.31.75 node_name=k8s-node3
2)执行部署
# ansible-playbook -i hosts add-node.yml -uroot -k
部署产生的证书都会存放到目录“ansible-install-k8s-master/ssl”,一定要保存好,后面还会用到~
