How to View Deployed Files for a Web App Using the Azure Portal

When debugging a web app and tracking down problems, especially newly created and deployed apps that aren't working, sometimes all that's needed is to look and see what's deployed to help determine the issue. This is trivial to do using the App Service Editor available from the Azure Portal.

Once logged into the portal, navigate to the website or specific deployment slot of the app where you'd like to browse the files. Viewing the menu of options on the left-hand side, select App Service Editor:

This will redirect to a location in a new browser tab which will show the folder structure and physical files present. Within the utility there are other useful functions available along the left-hand side in addition to the logging output to help diagnose and have insight into your deployed site.

This feature is still in 'Preview' mode so expect some changes over time to the utility, possibly being renamed, and on occasion being down. As noted you can always FTP into the directory as well as a secondary option.

Generate YAML from an Existing Azure DevOps Pipeline

Here's a quick tip if needing to generate a .yml file for CI/CD configuration from an existing Azure DevOps pipeline. There are several ways to build the .yml configuration file:

  • Make one from scratch
  • Use a template from GitHub or another similar project
  • Use the AzureDevOps pipeline editor and assistant
  • Use an auto-generated one created from a cloud portal (i.e. Azure portal)
However if the above solutions or any other aren't providing to be fruitful to your deployment configuration, you can leverage the classic editor from ADO to create a pipeline configuration visually via steps. This is often a means to an end to get working syntax in a methodical manner via form input, rather than through raw configuration.

Once you have a working pipeline however, it's ideal to get this configuration into your GitHub repository. This allows source control tracking on the configuration which is preferred to a pipeline used in a vacuum. If you used the classic editor to build a working pipeline, generating a .yml configuration is trivial. 

In ADO, navigate to the pipeline and find the ellipse next to, 'Run Pipeline.' From this menu you'll see an option to, 'Export to YAML.'

This will generate a .yml configuration file based on your working pipeline.

At this point you could add the .yml file to source control and create a new Azure pipeline connecting to your source control provider that leverages the newly created file.

Note different deployment systems use different YAML syntax or 'actions' so this may not be directly portable to another workflow for deployment. For example the .github/workflows directory in GitHub can connect to the repo from the Azure Portal in the Deployment configuration and use a .yml file. However the syntax is different for GitHub Actions, so the .yml file downloaded would only be a guide and require further massaging.

How to Activate an Azure Monthly Credit With Another Account When Subscription Login Denies Benefit

Scenario: You've been assigned Visual Studio Subscription (AKA MSDN subscription back in the day) by your organization, and would like to activate your free $150 (or similar) credit. Upon attempting the credit you get an error along the lines of, "You're not eligible with this benefit. Your organization does not allow activating this benefit." However you know the Azure credit is a benefit as it's listed as such on your subscription. Why an organization would block this benefit, I'm not sure nor how to inquire about resolving, but there's a simple solution.

Context: You switch companies, switch emails, a subscription expires, another is activated. This inconsistency creates havoc for your personal development and OSS work as all of your Azure resources have to be recreated over and over for new subscriptions (Note: moving resources is typically not an option as you can only do this across the same underlying subscription; see: Move Azure Resources). Now you've gone to login to your new subscription to use the Azure credit, and the benefit isn't allowed to be activated. Ideally you have a single, static, non-changing account login that you can associate varying subscriptions with over the years. The recommendation IMO is to use your personal GitHub login to associate Azure credits for 1...n Visual Studio Subscriptions. 

Solution: You can add an 'Alternate Account' to your Visual Studio subscription, that can be assigned the credit instead to associate with your current subscription. 

  1. Log into your active and current Visual Studio subscription. Under the 'Benefits' tab there will be a box to active your Azure monthly credit:

  2. Upon selecting 'Activate' you'll be presented with a Microsoft login to proceed to the Azure Portal. If you select logging in with your organization's login which is the same as your Visual Studio subscription login, you get an error that the benefit is not allowed to be used for this ID: 

  3. Back in Visual Studio subscriptions, head over to the 'Subscriptions' tab:

  4. Add an alternate email that you'd like to associate with your Azure credit. Essentially this allows using that credit, with another valid Microsoft or SSO login. My suggestion is to associate the email with your personal GitHub login. This will help set you up in the future to be able to re-associate new subscriptions with the same login to ease transition. Note - whichever account you choose, this whole process will be much easier if it's already established as a Microsoft account and have previously logged into the Azure portal ( 

  5. After adding the alternate email, go back to the 'Benefits' tab and press 'Activate' for the Azure credit again (Step #1). This time when presented with the login, use the alternate email credentials. For a GitHub login, select 'Sign on options' and SSO authenticate with GitHub. If you used another Microsoft login as the alternate account, use those credentials.

  6. If you get a login error regarding STS or federation error (i.e. AADSTS900043 or similar), just close the browser tab and reopen This seems to be a 1-off issue with the handshake and has nothing to do with this overall process.

  7. Once successfully logged in your Azure monthly credit will be applied to the alternate email ID login you configured. To check the status, you can view your subscription(s) from the 'Settings.' 

One final note - once this process is done and as expected, if you try and activate again with another login (i.e. your organization's login, another email, etc.), you'll be presented with the message that this benefit is already used and can't be activated again. I'm not sure on how to re-link the monthly credit, so ensure the login you setup is the one you want to use.
