Sample WebApp and WebJob in python hosted via Azure App Service.

This consists of a Flask App that will place jobs in an Azure Service Bus Queue along with a Worker (WebJob) that processes items on the Service Bus Queue.

1. Create a config.yml file in the project root - next to deploy.cmd.

• A full example file can be found at the bottom of this readme

2. Create Service Bus Namespace

• Put the name in config.yml under key SERVICE_BUS_NAMESPACE

3. Create Service Bus Queue under the namespace

• Put the queue name in config.yml under SERVICE_BUS_QUEUE_NAME
• Check Lock Duration timer and make sure it is 30 seconds
• Create a shared access policy named with properties send and listen
• Put the shared accesskey name & shared accesskey value in config.yml under SERVICE_BUS_QUEUE_ACCESS_KEY_NAME, SERVICE_BUS_QUEUE_ACCESS_KEY_VALUE

4. Finish preparing the config.yml with a few basic values:

• LOCAL: True
• SERVER_HOST: "localhost"
• SERVER_PORT: 80

1. To start the server, navigate to the project root and run python runserver.py

• Open your webrowser and go to http://localhost You should see Hello, World!
• Neviaget to http://localhost/test You should see a message being enqueued with the current timestamp.

2. To start the worker, navigate to the project root and run python runworker.py

• You should see a console trace immediately processing the message you previously sent

1. Create a Resource Group in Azure RM
2. Create App Service WebApp

• Set the Python Version in Settings -> Application Settings to 3.4

3. Create WebJob for worker (under Settings -> WebJobs)

• Select the continuous WebJob option
• Upload a dummy file for now. (It must have a .exe, .py, etc. extension to upload)
• Take the WebJob name, and put this in sampleapp.worker/__init__.py as name = 'WHATEVER_NAME_YOU_CHOSE'

4. Set environmental variables (from config.yml) in Settings -> Application Settings under app settings.

• Copy Key and Values from config.yml precisely. (Leave out LOCAL: True from Azure though)
• Don't use quotations when pasting values in Azure App Settings.

5. Create deployment credentials (under Settings -> Publishing)
6. Go to Deployment source and chose the source Local Git Repository
7. Add this as a remote to your local git repo. Name this remote azure

• git remote add azure https://[email protected]:443/NeedsMoreGit.git

8. Deploy via git push azure master

• If you rename the "sampleapp" python package, or the server/worker packages, you need to make the following changes.
• Replace all package imports with the new name. Don't forget to also replace
• deploy_job.py
• runserver.py
• runworker.py
• web.config:
• You should not modify ptvs_virtualenv_proxy.py

LOCAL: True
SERVICE_BUS_NAMESPACE: "serviceBusNameSpace"
SERVICE_BUS_QUEUE_NAME: "nameServiceBusQueue"
SERVICE_BUS_QUEUE_ACCESS_KEY_NAME: "whatevernameyouchoose"
SERVICE_BUS_QUEUE_ACCESS_KEY_VALUE: "yourkey!!"
SERVER_HOST: "localhost"
SERVER_PORT: 80
