一、管理namespace

1.1 创建namespace

kubectl create namespace taos

1.2 namespaces列表

kubectl get namespaces -o wide

二、配置3份yaml文件

2.1 tdengine3-storage-class.yaml

创建name=tdengine3-storage-class、namespace=taos的存储类名

---
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:name: tdengine3-storage-classnamespace: taos
provisioner: diskplugin.csi.alibabacloud.com

2.2 taosd-service.yaml

创建name=taosd、 namespace=taos、app=tdengine的Service

---
apiVersion: v1
kind: Service
metadata:name: "taosd"namespace: "taos"labels:app: "tdengine"
spec:ports:- name: tcp6030protocol: "TCP"port: 6030- name: tcp6041protocol: "TCP"port: 6041selector:app: "tdengine"

2.3 taosd-tdengine.yaml

创建StatefulSet服务，需要关注以下参数与上述步骤设置的参数一致

• name: “tdengine”
• namespace: “taos”
• storage: “20Gi”(磁盘alicloud-disk-efficiency最低20Gi才能分配成功)
• storageClassName: “tdengine3-storage-class”

---
apiVersion: apps/v1
kind: StatefulSet
metadata:name: "tdengine"namespace: "taos"labels:app: "tdengine"
spec:serviceName: "taosd"replicas: 3updateStrategy:type: RollingUpdateselector:matchLabels:app: "tdengine"template:metadata:name: "tdengine"labels:app: "tdengine"spec:containers:- name: "tdengine"image: "tdengine/tdengine:3.0.0.0"imagePullPolicy: "IfNotPresent"ports:- name: tcp6030protocol: "TCP"containerPort: 6030- name: tcp6041protocol: "TCP"containerPort: 6041env:# POD_NAME for FQDN config- name: POD_NAMEvalueFrom:fieldRef:fieldPath: metadata.name# SERVICE_NAME and NAMESPACE for fqdn resolve- name: SERVICE_NAMEvalue: "taosd"- name: STS_NAMEvalue: "tdengine"- name: STS_NAMESPACEvalueFrom:fieldRef:fieldPath: metadata.namespace# TZ for timezone settings, we recommend to always set it.- name: TZvalue: "Asia/Shanghai"# TAOS_ prefix will configured in taos.cfg, strip prefix and camelCase.- name: TAOS_SERVER_PORTvalue: "6030"# Must set if you want a cluster.- name: TAOS_FIRST_EPvalue: "$(STS_NAME)-0.$(SERVICE_NAME).$(STS_NAMESPACE).svc.cluster.local:$(TAOS_SERVER_PORT)"# TAOS_FQND should always be set in k8s env.- name: TAOS_FQDNvalue: "$(POD_NAME).$(SERVICE_NAME).$(STS_NAMESPACE).svc.cluster.local"volumeMounts:- name: taosdatamountPath: /var/lib/taosreadinessProbe:exec:command:- taos-checkinitialDelaySeconds: 5timeoutSeconds: 5000livenessProbe:exec:command:- taos-checkinitialDelaySeconds: 15periodSeconds: 20volumeClaimTemplates:- metadata:name: taosdataspec:accessModes:- "ReadWriteOnce"storageClassName: "tdengine3-storage-class"resources:requests:storage: "20Gi"

三、服务部署

3.1 部署StorageClass

Kubectl apply -f tdengine3-storage-class.yaml

3.2 部署Service

kubectl apply -f taosd-service.yaml 

3.3 部署StatefulSet

kubectl apply -f tdengine.yaml

3.4 查看启动日志

kubectl exec -it tdengine-0 -- tail -f /var/log/taos/taosdlog.0 

四、TDengine功能验证

4.1 验证：创建、查询

Query OK, 20 rows in database (0.008757s)

4.2 三副本节点功能验证

当在三副本的集群中创建二副本的数据库会有错误提示：

taos> create database if not exists test_0 replica 2;DB error: Invalid option replications: 2, only 1, 3 allowed (0.000204s)
