kubeadm-config说明

https://www.cnblogs.com/breezey/p/11770780.html

配置kubeadm-config.yaml
通过如下指令创建默认的kubeadm-config.yaml文件：

kubeadm config print init-defaults  > kubeadm-config.yaml

#生成KubeletConfiguration示例文件 
kubeadm config print init-defaults --component-configs KubeletConfiguration

#生成KubeProxyConfiguration示例文件 
kubeadm config print init-defaults --component-configs KubeProxyConfiguration

安装master节点：

kubeadm init --config kubeadm-config.yaml

---

生成用于添加节点的kubeadm-config.yaml文件

kubeadm config print join-defaults > kubeadm-config.yaml

修改三个地方：

• apiServerEndpoint：连接apiserver的地址，即master的api地址，这里可以改为192.168.0.1:6443,如果master集群部署的话，这里需要改为集群vip地址
• token及tlsBootstrapToken：连接master使用的token，这里需要与master上的InitConfiguration中的token配置一致
• name：node节点的名称，如果使用主机名，需要确保master节点可以解析该主机名。否则的话可直接使用ip地址

添加节点：

kubeadm join --config kubeadm-config.yaml
