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?

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

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.

Answer 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.

Answer 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.

Answer 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"

Answer 6

I had the same issue after following AWS's docs to the dot. What I did to avoid it was initialize an application through the EB CLI step by step, without using the command the AWS docs instructed (~/ebdjango$ eb init -p python2.7 django-tutorial), and creating an environment step by step as well. The steps I took in the EB CLI are the following:

1. Initialize Application
   1. eb init
   2. Select a default region
   3. Enter Application Name (used default by pressing enter)
   4. Confirmed that I am using Python
   5. Selected Python version compatible with my local environment
   6. Set up SSH
2. Create Environment
   1. eb create
   2. Enter Environment Name (used default by pressing enter)
   3. Enter DNS CNAME prefix (used default by pressing enter)
   4. Select a load balancer type (I selected classic by entering 1)

After Environment is created I use eb config to open EB's config file to confirm that the path to my WSGI is what it should be:

aws:elasticbeanstalk:container:python:
  NumProcesses: '1'
  NumThreads: '15'
  StaticFiles: /static/=static/
  WSGIPath: path/to/wsgi.py

If any changes are made, make sure you save the file and confirm that everything is squared up by entering eb open in your terminal to open a browser window using the domain name specified in previous steps.
