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
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
2)执行部署
ansible-playbook -i hosts add-node.yml -uroot -k
3)在Master节点允许颁发证书并加入集群
kubectl get csr
kubectl certificate approve node-csr-xxx
