下载 kuboard 部署清单

# wget https://addons.kuboard.cn/kuboard/kuboard-v3-swr.yaml

修改部署清单 configmap

# vim kuboard-v3-swr.yaml

修改内容

# KUBOARD_AGENT_KEY 是 Agent 与 Kuboard 通信时的密钥，请修改为一个任意的包含字母、数字的32位字符串，此密钥变更后，需要删除 Kuboard Agent 重新导入。
  KUBOARD_AGENT_KEY: 32b7d6572c6255211b4eec9009e4a816

确认 etcd 节点数量

在集群中 Master Role 节点不足3个个时， 需要在 worker 节点添加 k8s.kuboard.cn/role=etcd 的标签，使etcd最少为奇数3个节点。
添加 label 命令：
kubectl label nodes your-node-name k8s.kuboard.cn/role=etcd

部署 kuboard

# kubectl apply -f kuboard-v3-swr.yaml
