Running WebDC3 as standalone with gunicorn

[volcan01010]

Hi,

I realise that this is not the preferred method, but I am trying to run WebDC3 from a user home directory, without Apache (I have permission problems accessing system level folders on server). I am using the gunicorn wsgi runner for Python.

I have been following the instructions in operator.rst. I have symlinked my webinterface.cfg into the seiscomp3/etc/ directory and set the SERVER_FOLDER. I copied the generic html files to the project root directory.

The repository is checkout out in /home/eida/webdc3/webdc3-github. I use the following command to start the server from within the wsgi directory:

gunicorn webinterface:application --log-level DEBUG \
  --chdir /home/eida/webdc3/webdc3-github \
  --env SEISCOMP_ROOT=/home/eida/seiscomp3 \
  --env LD_LIBRARY_PATH=/home/eida/seiscomp3/lib \
  --env PYTHONPATH="/home/eida/webdc3/webdc3-github/wsgi;/home/eida/seiscomp3/lib/python"

When I try to access the webserver, I get 404 errors. e.g.

curl localhost:8000/
curl localhost:8000/index.html
curl localhost:8000/webinterface

The debug logs record the GET requests.

However the following query does work:

curl localhost:8000/request/types.

Do you have any idea how I can fix this?

Thanks,
John

I'm not familiar with gunicorn, but unless it has built-in webserver functionality to serve static files (index.html, css, javascript, images), you may need to run it in combination with a web server like nginx. We are actually running nginx+uwsgi.

Interesting. Can you share NGINX config somewhere, please? My aim is to get it all running in Docker.

Here is the nginx config that I dropped in /etc/nginx/conf.d:

server {
        listen 80 default_server;
        listen [::]:80 default_server;

        root /var/www/html;
        index index.html;

        location / {
                # First attempt to serve request as file, then
                # as directory, then fall back to displaying a 404.
                try_files $uri $uri/ =404;
        }

        location = / {
                return 301 /webdc3/;
        }

        location /webdc3/data/ {
                return 404;
        }

        location /webdc3/wsgi/ {
                include uwsgi_params;
                uwsgi_pass localhost:9000;
        }
}

If you use gunicorn, you'd probably use "proxy_pass" instead of "uwsgi_pass". We run uwsgi using:

source <(/sbin/setuser sysop /home/sysop/seiscomp3/bin/seiscomp print env)
exec /usr/bin/uwsgi --master --processes 8 --die-on-term --socket 127.0.0.1:9000 --uid sysop --plugins syslog,python --logger syslog --manage-script-name --mount /webdc3/wsgi=/var/www/html/webdc3/wsgi/webdc3.wsgi

Thanks. I'll have a go and let you know how I get on.

Thanks. I'll have a go and let you know how I get on.

@volcan01010 Did you dockerized it? It will save a lot of time, if you could share it.

Hi all,

Has anyone created a Docker container for webdc3?

Thanks,
