Azure App Services Diagnostics Portal And Applens

This is the repository for Azure App Service diagnostics experience.

Running the project locally:

• Install Node 18.15.*
  • Only version 18.15.* will work for this project as there are dependency changes in latter version of Node which our project is incompatible with.
• Run npm install
• Build the diagnostic-data lib, Applens and Diagnostics Portal: npm run build
• Run the project locally:
  • To run Applens: npm run applens
  • To run Diagnostics Portal: App Service Diagnostics Portal

Getting Started

• Clone repo git clone https://github.com/Azure/Azure-AppServices-Diagnostics-Portal.git
• Choose one of the two options below:
  • Setup local machine: Install required dependencies locally by navigating to the angular root folder AngularApp and runing npm install (This will install all the required packages.) OR
  • Docker container: Build and run a docker container that has all necessary dependencies.
    • Install and run the docker desktop client.
    • Run AngularApp/buildimage.sh (or buildimage.bat on Windows) once to build an image locally.
    • Create a container from the image created above by running AngularApp/startcontainer.sh (or startcontainer.bat on Windows) to build a container and open a terminal session on it. Alternately you can use the docker desktop UI to stop/start and open a terminal to the container.
    • From within the container, cd to the AngularApp folder and restore packages via npm install to install npm packages.
    • Continue to the next section. Note: if you are only developing the diagnostic portal and not the backend, you can skip steps 2, 3 and 4. In step 6, if working on Windows, run npm run ssl-local-poll as angular running in the container is unable to monitor the filesystem for changes (auto-recompile on file change)

App Service Diagnostics Portal

Set Up a Local Development Environment

1. Create a Local Environment Settings file
   • Copy AngularApp\projects\app-service-diagnostics\src\environments\environment.ts to create AngularApp\projects\app-service-diagnostics\src\environments\environment.local.ts
   • Set key "useApplensBackend" to true
2. Get Resource Auth Token from ARM Client:
   • Install ArmClient: choco install armclient
     • Ensure source chocolatey is enabled: choco source enable -n=chocolatey
   • Log in to ArmClient: ARMClient.exe login
   • Run ARMClient.exe token {SubscriptionID} with your Subscription ID, which will copy the Auth Token to the clipboard
3. Add Auth Token and ResourceID to Local Environment Settings:
   • Paste the ArmClient token from the above step into authServiceToken in environment.local.ts
   • Copy the ID of a Resource you want to test, and paste it into authServiceResourceId in environment.local.ts
4. Skip Authorization in ApplensBackend
   • Open appsettings.Development.json
   • Set "ServerMode": "internal"
5. Create a self-signed certificate for Applens
   • Navigate to AngularApp\ssl
   • Follow the instructions in AngularApp\ssl\README.md to create a self-signed certficate and install the certificate for your local machine in Trusted Root
6. Run the SSL server
   • Run npm run ssl-local
   • Navigate to https://localhost:3000 to confirm the server is up

Testing Local Changes in the Azure Portal

• Navigate to the Auzure portal with website extension specified as local: Local Portal Test URL
• This will load the "Diagnose and solve problems" iframe from https://localhost:3000. (Must be running in ssl mode).
• Any changes made to the locally hosted project will be automatically refreshed in the Portal

Testing Local Changes in the Portal

• In order to test your local changes in the portal, you can use the following links:
  • Local: This will load the iframe from https://localhost:3000. Must be running in ssl mode (npm run ssl).
  • Staging: This will load the iframe from https://supportcenter-bay-staging.azurewebsites.net

Back End

• Right now the back end is optional as it is not required for functionality of the angular project.
• You will need appropriate secrets to be added to appsettings.Development.json.
• Open the Backend project in Visual Studio 2017 and run it in IIS Express mode.

Production Build

• The production build commands for the angular projects are as follows:
  • npm run build-applens - Build Applens. Build output is placed in ApplensBackend/wwwroot.
  • npm run build-asd - Build App Service Diagnostic Portal. Build output is placed in Backend/wwwroot.
  • npm run build - Build both App Service Diagnostic Portal and Applens.
• If you have the appropriate Publishing Profiles, you can deploy these changes to the staging slots.
• TODO: Azure Dev Ops Integration
