Study Notes
Azure App Service Web App for Containers
- You can host native Linux applications in the cloud by using Azure Web Apps.
- To create a Web App for Containers, you need to run Azure CLI commands that create a resource group, then a service plan, and finally the web app itself.
- The three Azure CLI commands to create the solution are:
- az group create
- az appservice plan create
- az webapp create
Provisioning an App Service Web App
- To provision an App Service Web App, you need to create a resource group, an App Service plan, and a web app.
- The web app can be used to host a Docker image and map a custom domain to the App Service web app.
Creating a Dockerfile
- A Dockerfile document is required to create a Docker image that runs an ASP.NET Core application.
- The Dockerfile document should be created in the same folder where the application files are stored.
- The five commands to create the Dockerfile are:
- CMD [..]
- FROM microsoft/aspnetcore-build:latest
- WORKDIR /apps/ContosoApp
- COPY ./.
- RUN powershell ./setupScript.ps1
Configuring an Azure Function App
- To configure an Azure Function App, you need to choose a plan that minimizes latency.
- A Consumption plan with an Azure Blob Storage trigger is recommended to process images quickly after they are uploaded.
- The Function App should be configured to use an Azure Blob Storage trigger to minimize latency.
Azure CLI Commands
- The Azure CLI commands to create a web app in an App Service plan are:
- az webapp create
- az webapp config container set
- az webapp config hostname add
- The commands should be used in the correct order to develop the solution.
Serverless Java Application on Azure
- To develop a serverless Java application on Azure, you need to create a new Azure Key Vault to work with secrets from a new Azure Functions application.
- The application must meet the requirements of referencing the Azure Key Vault without requiring any changes to the Java code, dynamically adding and removing instances of the Azure Functions host, ensuring that instances are perpetually warm, and connecting to a VNet.
