我正在尝试在 Kubernetes 上部署最新的 docker 镜像 apache:superset。当我部署 YAAML 时，出现以下错误：

它似乎正在尝试连接到默认 SQLLite。我试图在 config.py 中提供 postgres 凭据，但无法修改图像中的文件。我的 Docker 文件中有以下命令：

USER root
COPY updated_config.py /app/superset/config.py
USER superset

该命令运行正常，但没有更新文件。如何更新 config.py。我也尝试在 YAML 中使用 Config Map，但这也给出了错误：

"ModuleNotFoundError: No module named 'superset.app'"

请提出建议。谢谢

【解决方案1】：

您分享的错误应该只在我们没有运行superset db upgrade时发生。
您不应替换完整的默认配置文件。而是使用 export SUPERSET_CONFIG_PATH 创建新文件并添加必要的变量。

这里是 Dockerfile

FROM apache/superset
USER root

USER superset
EXPOSE 8088

RUN superset fab create-admin \
               --username admin \
               --firstname Superset \
               --lastname Admin \
               --email admin@superset.com \
               --password admin

COPY updated_config.py /app/config.py
RUN export SUPERSET_CONFIG_PATH=/app/config.py
RUN superset db upgrade

RUN superset init

由于您已经在使用 kubernetes，我建议您通过 helm chart 安装 superset。
