# GitHub-Azure-Function-Proxy-for-ARM-Template
ARM templates expect a public URL to download your templates.  This allows you to use your private GitHub repo for Azure Linked ARM templates.  The Azure Function is basically a proxy to GitHub.  You can edit the Azure Function for your source control provider of choice.

## Create the Azure Function
1. Create an Azure Function of type .NET named {Organization}GitHubProxy  (the function name needs to be globally unique)
2. Paste the Azure-Function.cs into a new function
3. Login into GitHub
   - Click on your name (top right)
   - Select Settings
   - Go to Developer Settings
   - Go to Personal Access Token
   - Click Generate New Token
   - Give it name
   - Select repo scope access
4. Paste your Personal Access Token into the Azure Function 
   - string personalAcccessToken = "{REMOVED}"; 

## To call the Azuze Function
- Press the "Get function URL" in the Azure Portal
- e.g. https://{functionAppName}.azurewebsites.net/api/{functionName}
- Add the query string &location={raw url in GitHub}
- Sample: https://{functionAppName}.azurewebsites.net/api/{functionName}?location=https://raw.githubusercontent.com/AdamPaternostro/GitHub-Azure-Function-Proxy-for-ARM-Template/master/README.md
- You can test this in a browser window

## To Run via command line (Linux)
- You need to change the URL in the azuredeploy.json
