I have passes AZ-900 Microsoft Azure Fundamentals exam. Find the verified badge in below link.
I am using Azure cloud shell to create a web app. I am opening https://portal.azure.com and click on the cloud shell button to open cloud shell window inside web browser. I am using bash and Azure Cli.
Create a new resource group.
az group create --name webapprg-1602 --location northeurope
Create a new app service plan.
az appservice plan create --name appserviceplan-1602 \ --resource-group webapprg-1602

There is a misconception that Azure PowerShell works only on Windows and Azure CLI works everywhere. This is not true. PowerShell (not Windows PowerShell) is based on .NET Core which is cross platform. We can run PowerShell on Windows as well as on Linux. Both Azure PowerShell and Azure CLI runs on Windows and Linux.
Which option you will choose depends on your personal preference and from what background you are coming. If you are already working on PowerShell then Azure PowerShell should be your choice but if you are more like a person who works with for example Bash, then Azure CLI will be a good option for you. Also sometimes people find Azure CLI commands are more easy to type and remember.
This is a personal preference.
Create a console app
I have created a new .NET 5 console app.
<Project Sdk="Microsoft.NET.Sdk"> <PropertyGroup> <OutputType>Exe</OutputType> <TargetFramework>net5.0</TargetFramework> <Nullable>enable</Nullable> </PropertyGroup> </Project>
using System; Console.WriteLine("Hello World!");
I have published the app in a folder.
In the publish folder I found the below files.
To test the published app, I have opened a terminal and navigate to the published folder and execute below command.
This should print ‘Hello World!’ in the terminal.
Create container image with Docker
I have WSL 2 installed in my Windows 10 machine and I have Ubuntu installed. I have installed Docker desktop for WSL. I have created a new folder ‘ConsoleApp1’ in the Ubuntu home folder and put the published artefacts inside that.
I have opened Widows Terminal and connect Ubuntu Bash with it. Navigate to the ‘ConsoleApp1’ folder. Type code . to open VS Code.
Add a new file with name ‘Dockerfile’ in the folder.
In VS Code write the below code in the Dockerfile.
FROM mcr.microsoft.com/dotnet/runtime:5.0 COPY . ./app WORKDIR /app ENTRYPOINT ["dotnet", "ConsoleApp1.dll"]
In the terminal run below command to create a Docker image.
docker build -t 45862391/consoleapp1:v1 .
Check the image successfully created or not.
To push the image to Docker Hub, run the below command in terminal.
docker push 45862391/consoleapp1:v1
Create a container with Azure Container Instances
Open Azure Portal and create a new Container Instance resource.
After the successful creation of the resource I can check the logs for the output of my console app.
Now my .NET 5 console app is deployed to Azure Container Instance from Docker Hub image.
- Create a .NET 5 console app.
- Publish it in a folder.
- Create a Dockerfile.
- Create Docker image and push to Docker Hub.
- Create a Azure container instance based on Docker Hub image.
If you are using Azure to host your application then how you create resources in Azure? Azure Portal is a very good option to create resources in Azure. You can see all the options in the very user friendly interface. If you are new in Azure then Azure Portal is a very good option to start.
