Azure Kubernetes Service with .NET Core

Introduction

In at this time’s quickly evolving software program panorama, builders are more and more turning to containerization and orchestration platforms to deploy and handle their purposes effectively. Azure Kubernetes Service (AKS) gives a managed Kubernetes service that simplifies the deployment, administration, and scaling of containerized purposes in Azure. When mixed with the flexibility and efficiency of .NET Core, builders can construct and deploy fashionable, scalable purposes with ease. On this information, we’ll discover easy methods to leverage Azure Kubernetes Service with .NET Core, offering step-by-step directions and real-world examples.

What’s Azure Kubernetes Service (AKS)?

Azure Kubernetes Service (AKS) is a completely managed Kubernetes service offered by Microsoft Azure. Kubernetes is an open-source container orchestration platform that automates the deployment, scaling, and administration of containerized purposes. AKS abstracts away the complexities of managing Kubernetes clusters, permitting builders to deal with constructing and deploying their purposes with out worrying concerning the underlying infrastructure.

What’s .NET Core?

.NET Core is a cross-platform, open-source framework for constructing fashionable, high-performance purposes. It permits builders to construct purposes utilizing C# or F# and run them on Home windows, macOS, or Linux. With its light-weight runtime and help for containerization, .NET Core is well-suited for constructing microservices and cloud-native purposes.

Getting Began with Azure Kubernetes Service and .NET Core

Conditions

Earlier than we start, be sure to have the next stipulations put in:

• Azure CLI: Set up the Azure CLI
• Docker: Set up Docker Desktop on your working system
• .NET Core SDK: Set up the .NET Core SDK

Step 1. Create an Azure Kubernetes Service Cluster

1. Open a terminal or command immediate and login to your Azure account utilizing the Azure CLI:

   az login

2. Create a useful resource group on your AKS cluster:

   az group create --name myResourceGroup --location eastus

3. Create an AKS cluster:

   az aks create --resource-group myResourceGroup --name myAKSCluster --node-count 3 --enable-addons monitoring --generate-ssh-keys

Step 2. Set up and Configure the Kubernetes CLI (kubectl)

1. Set up the Kubernetes CLI (kubectl) utilizing the Azure CLI:

   az aks install-cli

2. Get the credentials on your AKS cluster:

   az aks get-credentials --resource-group myResourceGroup --name myAKSCluster

Step 3. Construct and Containerize a .NET Core Utility

1. Create a brand new .NET Core internet software:

   dotnet new webapi -n MyApp

2. Navigate to the undertaking listing:

   cd MyApp

3. Construct the .NET Core software:

   dotnet construct

4. Create a Dockerfile within the undertaking listing:

   FROM mcr.microsoft.com/dotnet/core/aspnet:3.1 AS base
   WORKDIR /app
   EXPOSE 80
   
   FROM mcr.microsoft.com/dotnet/core/sdk:3.1 AS construct
   WORKDIR /src
   COPY ["MyApp.csproj", "."]
   RUN dotnet restore "./MyApp.csproj"
   COPY . .
   WORKDIR "/src/."
   RUN dotnet construct "MyApp.csproj" -c Launch -o /app/construct
   
   FROM construct AS publish
   RUN dotnet publish "MyApp.csproj" -c Launch -o /app/publish
   
   FROM base AS last
   WORKDIR /app
   COPY --from=publish /app/publish .
   ENTRYPOINT ["dotnet", "MyApp.dll"]
   

5. Construct and tag the Docker picture:

   docker construct -t myapp:v1 .

6. Check the Docker picture regionally:

   docker run -d -p 8080:80 myapp:v1

7. Open an online browser and navigate to http://localhost:8080 to confirm that the appliance is operating.

Step 4. Deploy the Utility to Azure Kubernetes Service (AKS)

1. Push the Docker picture to a container registry (e.g., Azure Container Registry):

   az acr login --name <registry_name>
   docker tag myapp:v1 <registry_name>.azurecr.io/myapp:v1
   docker push <registry_name>.azurecr.io/myapp:v1

2. Deploy the appliance to AKS utilizing a Kubernetes deployment manifest (deployment.yaml):

   apiVersion: apps/v1
   type: Deployment
   metadata:
     title: myapp-deployment
   spec:
     replicas: 3
     selector:
       matchLabels:
         app: myapp
     template:
       metadata:
         labels:
           app: myapp
       spec:
         containers:
         - title: myapp
           picture: <registry_name>.azurecr.io/myapp:v1
           ports:
           - containerPort: 80
   

3. Apply the deployment manifest to create the deployment:

   kubectl apply -f deployment.yaml

4. Expose the deployment as a Kubernetes service:

   kubectl expose deployment myapp-deployment --type=LoadBalancer --port=80 --target-port=80

5. Get the exterior IP tackle of the service:

   kubectl get service myapp-deployment

6. Open an online browser and navigate to the exterior IP tackle to entry the appliance operating in AKS.

Conclusion

On this article, we have explored easy methods to leverage Azure Kubernetes Service (AKS) with .NET Core to construct and deploy containerized purposes in Azure. By following the steps outlined above, you possibly can create an AKS cluster, containerize a .NET Core software, and deploy it to AKS with ease. Whether or not you are constructing microservices, internet purposes, or APIs, AKS and .NET Core present a strong mixture for contemporary software improvement within the cloud. Glad studying!
