在Kubernetes上部署apache:superset映像时出错

Question

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

sqlite3.OperationalError: no such table: logs

它似乎正在尝试连接到默认的SQLLite。我正在尝试在config.py中提供postgres凭证，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，但是不更新file.How，我可以更新config.py吗？我还尝试在YAML中使用Config Map，但也出现了错误：

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

请提个建议。谢谢

你分享的错误应该只在我们没有运行superset db upgrade.

• You的时候发生，

1. 不应该替换完整的默认配置文件。而是使用导出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

我建议你通过helm chart安装superset，因为你已经在使用kubernetes了。
