It is based on the demo application in my [Durable Functions Fundamentals course on Pluralsight](https://pluralsight.pxf.io/c/1192349/424552/7490?u=www%2Epluralsight%2Ecom%2Fcourses%2Fazure-durable-functions-fundamentals) 4 | 5 | To run this locally from Visual Studio you will need to create your own `local.settings.json` file with the following contents (filling in your personal email address and SendGrid key in order to be able to send emails): 6 | 7 | ``` 8 | { 9 | "IsEncrypted": false, 10 | "Values": { 11 | "AzureWebJobsStorage": "UseDevelopmentStorage=true", 12 | "AzureWebJobsDashboard": "UseDevelopmentStorage=true", 13 | "TranscodeBitRates": "1010,2020,3030", 14 | "SendGridKey": "Your-SendGrid-Key-Here", 15 | "ApproverEmail": "your@email.here", 16 | "SenderEmail": "any@example.email", 17 | "Host": "http://localhost:7071", 18 | "FUNCTIONS_WORKER_RUNTIME": "dotnet" 19 | } 20 | } 21 | ``` 22 | 23 | To run in the cloud, you will need to create a Function App, configure App Settings for each of the settings shown above, and push the code to it (you can use right-click publish in Visual Studio). 24 | 25 | To start an orchestration, you can simply call the starter function, making sure to include a video query string parameteter. When running locally, this URL will be: http://localhost:7071/api/ProcessVideoStarter?video=example.mp4 26 | 27 | If you are running in the cloud, the URL will look something like this: https://myfunctionapp.azurewebsites.net/api/ProcessVideoStarter?code=yoursecretfunctioncode&video=example.mp4 You can find your secret function authorization code by clicking the get URL link for your function in the portal. 28 | 29 | There is also a periodic task you can trigger with the `StartPeriodicTask` endpoint (available locally [here](http://localhost:7071/api/StartPeriodicTask)), but it will run forever, so remember to terminate the orchestration (you can use [`StopPeriodicTask`](http://localhost:7071/api/StopPeriodicTask), or delete the function app once you're done. 30 | 31 | -------------------------------------------------------------------------------- /.gitattributes: -------------------------------------------------------------------------------- 1 | ############################################################################### 2 | # Set default behavior to automatically normalize line endings. 3 | ############################################################################### 4 | * text=auto 5 | 6 | ############################################################################### 7 | # Set default behavior for command prompt diff. 8 | # 9 | # This is need for earlier builds of msysgit that does not have it on by 10 | # default for csharp files. 11 | # Note: This is only used by command line 12 | ############################################################################### 13 | #*.cs diff=csharp 14 | 15 | ############################################################################### 16 | # Set the merge driver for project and solution files 17 | # 18 | # Merging from the command prompt will add diff markers to the files if there 19 | # are conflicts (Merging from VS is not affected by the settings below, in VS 20 | # the diff markers are never inserted).
