即使在 chmod 777 之后"sqlite3.OperationalError: attempt to write a readonly database"

Question

我正在docker容器中运行一个Django应用程序。我收到这个错误sqlite3.OperationalError: attempt to write a readonly database。我已经尝试了Dockerfile 中的所有内容

RUN chown username db.sqlite3
RUN chmod 777 db.sqlite3

我也尝试以root用户的身份运行该应用程序，但仍然出现了同样的错误。

这是我的Dockerfile

FROM python:3.9.5-alpine
RUN addgroup -S apigroup && adduser -S weatherapi -G apigroup
WORKDIR /app
ADD requirements.txt .
RUN apk update && apk upgrade
RUN python3 -m pip install --upgrade pip && python3 -m pip install --no-cache-dir -r requirements.txt
COPY . . 
USER root
EXPOSE 8000
RUN chmod 777 db.sqlite3
USER weatherapi
RUN python3 manage.py migrate
CMD ["sh", "-c", "python3 manage.py runserver 0.0.0.0:8000"]

Answer 1

我只需要将基础图像更改为基于Debian的图像。

FROM python:3.8-buster

显然Alpine不喜欢SQLite。
