调研方向

首先定位用于初始化服务器和凭据的 IoTDB 入口点或启动脚本。跟踪初始 root 账户的创建方式,然后确定在首次启动期间可能读取 IOTDB_USER 和 IOTDB_PASSWORD 的位置。当容器化部署能够提供这些变量,并使用所请求的凭据启动而无需手动执行 ALTER USER 时,即表示完成。

Motivation

When deploying IoTDB in a containerized or orchestrated environment (e.g. Kubernetes), there is currently no way to set the initial user credentials through environment variables. The only documented approach is to start the server with default credentials, manually connect, and run:

ALTER USER root SET PASSWORD 'newpwd';

This is impractical for automated deployments where manual intervention is not an option.

Requested behavior:

The entrypoint/startup scripts should check for the presence of environment variables — for example IOTDB_USER and IOTDB_PASSWORD — and, if set, apply those credentials automatically on first startup. This would allow orchestration tools (Helm charts, Docker Compose, etc.) to inject credentials via secrets without requiring a manual post-deploy step.

Use case:

- name: IOTDB_USER
  valueFrom:
    secretKeyRef:
      name: iotdb-secret
      key: iotdb-user
- name: IOTDB_PASSWORD
  valueFrom:
    secretKeyRef:
      name: iotdb-secret
      key: iotdb-password

In a Kubernetes Helm chart, we inject IOTDB_USER and IOTDB_PASSWORD into the pod spec from a Secret:

The environment variables are present inside the container, but IoTDB ignores them entirely. The server starts with the default root/root credentials regardless.

Solution

If IOTDB_USER and IOTDB_PASSWORD are set, the startup scripts should apply them (e.g. by running the equivalent of ALTER USER root SET PASSWORD ...) so the instance is ready to use with the desired credentials without manual intervention.
