Hello,
I believe 19.12 is also a LTS version. Could you update the image ?
Thanks,
Damien
FROM sanicframework/sanic:LTS
RUN mkdir -p /srv # <-- by adding -p, it will do nothing if the folder already exists
COPY . /srv
WORKDIR /srv # <-- new
EXPOSE 8888
ENTRYPOINT ["python3", "my-sanic-server.py"] # <-- removed /srv/
If WORKDIR
is not set, all paths referred to in my-sanic-server.py
will start from root /
instead of /srv
. This breaks relative paths in "my-sanic-server.py"
when accessing other files in the container or e.g. creating logs.
I modified the Docker file found under base
to include SQLAlchemy and copied the equivalent of "my-sanic-server.py"
to /srv/
+ a SQLite3 database (sample.db
). My Python file uses a relative path to access sample.db
. I didn't have any problems when running locally, but in a Docker container I was getting errors as: sqlalchemy.exc.OperationalError: (sqlite3.OperationalError) no such table: foo
.
Originally I thought it was a permission problem ("users" inside a Docker container inheriting the same permissions of the host OS's user with the same UID
), but I finally found out that the issue was with the path. It was solved by setting WORKDIR
.
Also, RUN mkdir /srv
in your README to create Docker images based on FROM sanicframework/sanic:LTS
does not work, as it gives the error:
mkdir: cannot create directory ‘/srv’: File exists
