failed to open python file /app/opentopodata/api.py

[jsgonsette]

I followed the documentation to run the server in local, but the server cannot start, both on Windows and Linux. My command:

docker run --rm -it --volume "/mnt/e/Maps/SRTM:/app/data:ro" -p 5000:5000 -e N_UWSGI_THREADS=8 opentopodata sh -c "/usr/bin/supervisord -c /app/docker/supervisord.conf"

The logs I obtained:

Obviously the application complains about failed to open python file /app/opentopodata/api.py Any idea what I did wrong ?

Hmm, this could be a file permission issue.

If you run ls -lh opentopodata/api.py on the host machine you should get something like -rw-r--r--.

And if that looks ok, could you try the same command inside the docker container with something like

docker run --rm -it opentopodata  ls -lh /app/opentopodata/api.py

I tried those commands and I found out that the docker was obviously corrupted somehow. I restarted everything from scratch and now it works. Thanks

Thanks for following up! This is helpful for people with the same problem in the future!
