添加节点
KubeCube 提供为已有集群添加节点的能力
⚠️ 注意 node 机器需要能够通过 ssh 访问 master 机器,支持公钥和密码两种 ssh 方式,执行脚本前可以在 node 上 ssh 到 master 测试连通性
向集群添加工作节点
在新节点上执行部署脚本
KUBECUBE_VERSION=v1.0.0
export CUSTOMIZE="true";curl -fsSL https://kubecube.nos-eastchina1.126.net/kubecube-installer/${KUBECUBE_VERSION}/entry.sh | bash
tip: 你可以通过预先下载离线包和镜像来减少部署时间
export PRE_DOWNLOAD="true";curl -fsSL https://kubecube.nos-eastchina1.126.net/kubecube-installer/${KUBECUBE_VERSION}/entry.sh | bash
设置脚本参数,并按照提示继续运行安装脚本并等待新节点加入集群
- MASTER_IP 为 master 节点 ip
- LOCAL_IP 为新节点 ip
# if install kubecube on pivot cluster
INSTALL_KUBECUBE_PIVOT="false"
# if install kubecube on member cluster
INSTALL_KUBECUBE_MEMBER="false"
# if install k8s

# there are four node mode below:

# "node-join-master" : node will be install as a worker of cluster to join master
# "control-plane-master" : node will be installed as a master to control plane of cluster
# "node-join-control-plane" : node will be installed as a master to join control plane

向集群的 control-plane 添加 master 节点
在新节点上执行部署脚本
KUBECUBE_VERSION=v1.0.0
export CUSTOMIZE="true";curl -fsSL https://kubecube.nos-eastchina1.126.net/kubecube-installer/${KUBECUBE_VERSION}/entry.sh | bash
设置脚本参数,并按照提示继续运行安装脚本并等待新节点加入 control-plane
- MASTER_IP 需要填已有的 master 节点 ip
- LOCAL_IP 需要填新节点的节点 ip
- CONTROL_PLANE_ENDPOINT 为高可用 vip
