Question on Readonly DB error

Currently when i build the Dockerfile (the one in the root directory) and execute it… it works fine. Site comes up, no prob.

But, i am not able to add a dashboard. Im just trying to make sure this works properly before launching it to a production environment.

ERROR:flask_appbuilder.models.sqla.interface:Add record error: (sqlite3.OperationalError) attempt to write a readonly database
[SQL: INSERT INTO dashboards (created_on, changed_on, dashboard_title, position_json, description, css, json_metadata, slug, published, created_by_fk, changed_by_fk) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)]

How do I fix this readonly db issue? Thanks in advance, appreciate the help.

Thanks,it’s a really good and effective method. I think the reason of this question is the supert user and root user have different file permissions.

It’s my dockerfile,for you reference:

USER root

RUN pip install mysqlclient

RUN pip install sqlalchemy-redshift
RUN pip install PyMySQL

USER superset

RUN superset fab create-admin xxxxx

RUN superset db upgrade

RUN superset load_examples

RUN superset init```
