Django App Deployment to Azure Failing Via Three Methods (problems creating/accessing tmp files)

Question

I have been trying to upload the code from my Django app to Azure. Using multiple methods, it has been failing, with the log messages shown below. The failure seems to relate to the creation of temporary directories by Onyx build. To be transparent, I'm new to both Django and Azure.

First, I worked through the Azure tutorial (link below) and was able to get it working with minimal issues.

https://docs.microsoft.com/en-us/azure/app-service/tutorial-python-postgresql-app?tabs=bash%2Cclone

When I attempted to follow the same steps (using "webapp up") with my own app, I get the following error message:

Zip deployment failed. {'id': 'XXXXX', 'status': 3, 'status_text': '', 'author_email': 'N/A', 'author': 'N/A', 'deployer': 'Push-Deployer', 'message': 'Created via a push deployment', 'progress': '', 'received_time': '2020-10-21T13:59:11.0137785Z', 'start_time': '2020-10-21T13:59:11.3572791Z', 'end_time': '2020-10-21T13:59:34.2598809Z', 'last_success_end_time': None, 'complete': True, 'active': False, 'is_temp': False, 'is_readonly': True, 'url': 'https://att-informativeness-task.scm.azurewebsites.net/api/deployments/latest', 'log_url': 'https://att-informativeness-task.scm.azurewebsites.net/api/deployments/latest/log', 'site_name': 'att-informativeness-task'}. Please run the command az webapp log deployment show -n att-informativeness-task -g DjangoPostgres-attInform-rg

Running the command they recommend,

az webapp log deployment show -n att-informativeness-task -g DjangoPostgres-attInform-rg

I get:

[ { "details_url": null, "id": "XXXXXX", "log_time": "2020-10-21T13:59:11.2061269Z", "message": "Updating submodules.", "type": 0 }, { "details_url": null, "id": "XXXXXX", "log_time": "2020-10-21T13:59:11.324348Z", "message": "Preparing deployment for commit id '53d578b78c'.", "type": 0 }, { "details_url": null, "id": "XXXXXX", "log_time": "2020-10-21T13:59:11.6729002Z", "message": "Repository path is /tmp/zipdeploy/extracted", "type": 0 }, { "details_url": "https://att-informativeness-task.scm.azurewebsites.net/api/deployments/53d578b78cf941b986537b13d0e6dd06/log/cb3995cc-27c2-4ca7-af9e-f0ca9f2446b7", "id": "XXXXXX", "log_time": "2020-10-21T13:59:11.8452701Z", "message": "Running oryx build...", "type": 2 } ]

In the log file they link, it gives an error similar to that which I get from Bitbucket. As that's pasted below in more readable format, I won't paste it here.

After numerous attempts, I then tried to follow the instructions to push to an Azure directory, as described by the following link (replacing the runtime with "python:3.6").

https://docs.microsoft.com/en-us/azure/developer/javascript/tutorial-vscode-azure-cli-node-04

when running the command

git push azure master

I get the error message:

(As an aside, my pip version is 20.2.4)

Finally, I tried to link it to a bitbucket repository, as described in the link below.

In the Azure deployment center, it gave a "Failed" status, with the message below.

For all of these, it seems the issue centers on creating and accessing tmp directories. It's weird because the process worked with the Azure tutorial code. I tried to bring my own code in line with the example by the creation of files like "production.py" and "settings.txt," changing variables in my "settings.py" file, as well as following the recommendations after running,

python manage.py check --deploy

Really any suggestions would be welcome. Thanks!

Answer 1

Figured out what was going on. Thought I would post the answer here in case any other newbie runs into the same issue.

The problem was in the requirements.txt file. I had used the command,

pip freeze > requirements.txt 

then didn't go through the results. Turns out there were a number of packages with an "@file..." to the right. Those were causing the errors. I just deleted the "@file..." and replaced it with a specific version for the package.

Also, make sure you specify that psycopg is the binary, using.

psycopg2-binary==2.8.6
