Gunicorn Environment Variable Setting

Question

I\'m currently having difficulty passing environment variables into Gunicorn for my Django project. I\'m on the latest 19.1 version. I have a wsgi.py file like so:

Answer 1

You just have to export your environment variable.

export SERVER_ENV=TEST
export SERVER_ID=TEST
gunicorn -b 127.0.0.1:8080 --error-logfile - --access-logfile - app.wsgi:application

And in your code you can get them like that

os.getenv('SERVER_ENV')

Answer 2

I don't quite understand what you are trying to do here. If you pass environment variables in the bash command line, they are already in os.environ: there is no need to get them from anywhere else. The environ dictionary is made up of elements passed from the request, not the shell.

Answer 3

I got a similar problem when deploying gunicorn.service. And I passed environment variables to it by a file:

<on gunicorn.service>
[Service]
...
EnvironmentFile=/pathto/somefilewith_secrets
...

For example (cat /etc/systemd/system/gunicorn.service)

[Unit]  
Description=gunicorn daemon  
After=network.target  
  
[Service]  
User=ubuntu
Group=ubuntu
WorkingDirectory=/home/ubuntu/10008/digichainOpen
EnvironmentFile=/home/ubuntu/10008/digichainOpen/.env
ExecStart=/home/ubuntu/.local/share/virtualenvs/digichainOpen-Zk2Jnvjv/bin/gunicorn \
          --worker-class=gevent --workers 4 \
          --bind unix:/home/ubuntu/10008/digichainOpen/gunicorn.sock digichainOpen.wsgi:application
            
[Install]  
WantedBy=multi-user.target  

and the .env file can be:

my_var=someValue
some_secret=secretvalue
another_secret=blah
