Setting up Django on AWS Elastic Beanstalk: WSGIPath not found

Question

I've been trying for several days now to set up Django under Amazon Web Services' Elastic Beanstalk. I think the problem I'm hitting is this one:

ERROR - Your WSGIPath refers to a file that does not exist.

I followed the tutorial here and all goes well until the end of Step 6, but I can't for the life of me get anything to display other than the generic Elastic Beanstalk page from Step 5, #2. When I run

./manage.py runserver

on my local machine, everything works as it should, but I can't get that page to deploy. I first tried with a small Django site I wrote myself. It didn't work, so I deleted everything I'd done and tried again, that didn't work, so I deleted all that and tried again with a fresh django install. I tried that a bunch of times fiddling with little things, but I think I'm missing something major.

I added a python.config file as described in this tutorial.

Here's my file structure:

-.git/
-.mysite/
    -myapp/
        -__init__.py
        -models.py
        -tests.py
        -views.py
    -mysite/
        -__init__.py
        -settings.py
        -urls.py
        -wsgi.py
    -.ebextensions/
        -python.config
    -manage.py
    -mysite.db
    -requirements.txt

From my settings.py:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': 'mysite.db',
        'USER': '',
        'PASSWORD': '',
        'HOST': '',
        'PORT': '',
    }
}

Here's python.config:

container_commands:   01_syncdb:    
    command: "django-admin.py syncdb --noinput"
    leader_only: true

option_settings:
    - namespace: aws:elasticbeanstalk:container:python
      option_name: WSGIPath
      value: mysite/wsgi.py
    - option_name: DJANGO_SETTINGS_MODULE
      value: mysite.settings
    - option_name: AWS_SECRET_KEY
      value: <This is my secret key>
    - option_name: AWS_ACCESS_KEY_ID
      value: <This is my access key>

Is there another place I need to define my WSGIPath? Is there a way to do it through the AWS console? Should I just skip EB altogether and use EC2 directly?

From https://forums.aws.amazon.com/thread.jspa?messageID=396656&#396656

The ".ebextensions" directory must be in the root level directory of your application, but from the log output, the directory is instead in the "mysite/.ebextensions" directory. So for example, after following the django tutorial in the docs when you run "git aws.push" your root directory would look like this:

.
├── .ebextensions
│   └── python.config
├── .elasticbeanstalk
│   ├── config
├── .git
├── .gitignore
├── manage.py
├── mysite
│   ├── __init__.py
│   ├── settings.py
│   ├── urls.py
│   └── wsgi.py
└── requirements.txt

Instead of this:

.
└── mysite
    ├── .ebextensions
    ├── .elasticbeanstalk
    ├── .git
    ├── .gitignore
    ├── manage.py
    ├── mysite
    └── requirements.txt

Solution 2

Find .elasticbeanstalk/optionsettings.your-app-name in your app's root directory. Search for WSGIPath and make sure it's the path you intend. It looks like it defaults to application.py.

Solution 3

I had the same problem ("Your WSGIPath refers to a file that does not exist"), and finally found a solution:

• The problem: I was downloading the bundle of the project directly from GitHub ("Download Zip"), which maybe had an improper structure.
• The solution: I properly zip the files, without the main folder, using the Compress command. (cf http://docs.aws.amazon.com/elasticbeanstalk/latest/dg/using-features.deployment.source.html).

Note: At first, I was searching in the wrong direction, because EB was also showing this message: Error occurred during build: Command 01_migrate failed.. So I though the files, including the *.config, were correctly located.

Solution 4

Solution: using EBCLI

open eb config For me it showed WSGIPath: application.py Now Change it to

WSGIPath: my_app/wsgi.py

save and deploy.

Solution 5

Ok, here's what worked for me after trying a million things. You have to run eb update in order to update the environment.

So make sure .elasticbeanstalk/optionsettings.whatever-env has WSGIPath set to what you want it, and make sure .ebextensions/whatever.config has this:

option_settings:
  - namespace: aws:elasticbeanstalk:container:python
    option_name: WSGIPath
    value: whatever/wsgi.py

Then run eb update and it should work. Remember you have to set the alias to make sure your eb command actually works. For example:

alias eb="python2.7 ../AWS-ElasticBeanstalk-CLI-2.6.3/eb/linux/python2.7/eb"
