## 配置 ConfigMap 以下配置文件可以从 [GitHub 仓库](https://github.com/taosdata/TDengine-Operator/tree/3.0/src/tdengine) 下载。
为 TDengine 创建 `taoscfg.yaml`，此文件中的配置将作为环境变量传入 TDengine 镜像，更新此配置将导致所有 TDengine POD 重启。 ## 配置 Service 服务
```yaml 创建一个 Service 配置文件：`taosd-service.yaml`，服务名称 `metadata.name` (此处为 "taosd") 将在下一步中使用到。添加 TDengine 所用到的所有端口：

```
对于某些公有云环境，minikube 绑定在 127.0.0.1 IP 地址上无法通过远程访问，需要使用 kubectl proxy 命令将端口映射到 0.0.0.0 IP 地址上，再通过浏览器访问虚拟机公网 IP 和端口以及相同的 dashboard URL 路径即可远程访问 dashboard。
```

## 集群缩容 ## 集群缩容
TDengine 的缩容并没有自动化，我们尝试将一个三节点集群缩容到两节点。 由于 TDengine 集群在扩缩容时会对数据进行节点间迁移，使用 kubectl 命令进行缩容需要首先使用 "drop dnodes" 命令，节点删除完成后再进行 Kubernetes 集群缩容。
首先，确认一个三节点 TDengine 集群正常工作，在 TDengine CLI 中查看 dnode 的状态： 注意：由于 Kubernetes Statefulset 中 Pod 的只能按创建顺序逆序移除，所以 TDengine drop dnode 也需要按照创建顺序逆序移除，否则会导致 Pod 处于错误状态。
```
$ kubectl exec -i -t tdengine-0 -- taos -s "drop dnode 4"
```
```bash ```bash
$ kubectl exec -it tdengine-0 -- taos -s "show dnodes"

``` ```
想要安全的缩容，首先需要将节点从 dnode 列表中移除，也即从集群中移除： 确认移除成功后（使用 kubectl exec -i -t tdengine-0 -- taos -s "show dnodes" 查看和确认 dnode 列表），使用 kubectl 命令移除 POD：
```
kubectl scale statefulsets tdengine --replicas=3
```
最后一个 POD 将会被删除。使用命令 kubectl get pods -l app=tdengine 查看POD状态：
```
$ kubectl get pods -l app=tdengine
NAME READY STATUS RESTARTS AGE
tdengine-0 1/1 Running 0 4m7s
tdengine-1 1/1 Running 0 3m55s
tdengine-2 1/1 Running 0 2m28s
```
POD删除后，需要手动删除PVC，否则下次扩容时会继续使用以前的数据导致无法正常加入集群。
```bash ```bash
kubectl exec -i -t tdengine-0 -- taos -s "drop dnode 'tdengine-2.taosd.default.svc.cluster.local:6030'" $ kubectl delete pvc taosdata-tdengine-3
```
通过 `show dondes` 命令确认移除成功后，移除相应的 POD：
```bash
kubectl scale statefulsets tdengine --replicas=2
```
最后一个 POD 会被删除，使用 `kubectl get pods -l app=tdengine` 查看集群状态：
```
NAME READY STATUS RESTARTS AGE
tdengine-0 1/1 Running 0 3h40m
tdengine-1 1/1 Running 0 3h40m
```
POD 删除后，需要手动删除 PVC，否则下次扩容时会继续使用以前的数据导致无法正常加入集群。
```bash
kubectl delete pvc taosdata-tdengine-2
``` ```
此时的集群状态是安全的，需要时还可以再次进行扩容： 此时的集群状态是安全的，需要时还可以再次进行扩容：
