Upload issues when running Zesje as Docker container
Zesje uses nginx for proxy, but the upload size limit is the default for nginx. For most uploads of scanned exams, this is not enough. I changed line 7 in auto.Dockerfile to:
RUN echo "server { client_max_body_size 128M; listen 80; location / { proxy_pass http://127.0.0.1:5000; } }" > /etc/nginx/sites-enabled/proxy.conf to resolve this issue.
