1.2 Dockerfile通过源码方式构建镜像，同时支持 AMD64 & ARM64 系统

1.3 生成镜像docker build -t tdengine:2.4.0.0 .
2、安装集群 2.1 创建 namespace$ mkdir ~/taos && cd $_$ cat > taos-namespace.yml <
$ cat > taos-configmap.yml <
暂时使用本地文件系统，可换成 Ceph 等
# 1、所有节点上，挂载相应的存储盘或路径$ mkdir -p /data/tdengine# 2、创建PV$ cat > taos-pv.yml <
$ cat > taos-pvc.yml <
$ cat > taos-headless.yml <
$ cat > taos-app.yml <
cat > taos-external-svc.yml <
登录到容器中，执行命令检查集群状态

3.2 restful容器外部，使用restful接口访问，注意：容器外，无法之间使用taos客户端连接
