.NET Core Web API Starter Project

This is a boilerplate template for building / deploying a .NET Core Web API microservice on Kubernetes / Azure Container Instance. This leverages .NET 6, new hosting model, and new routing API to enhance .NET performance. You can learn .NET 6 more on ASP.NET Core minimal APIs.

• Dockerfile is .NET Core Web API Multistage Dockerfile (following Docker Best Practices)
• KubernetesLocalProcessConfig.yaml is Bridge to Kubernetes config to supports developing .NET Core Web API microservice on Kubernetes
• configs folder will contain .NET Core Web API centralized config structure
• appsettings.Development.json is .NET Core Web API development environment config
• manifests folder will contain Kubernetes manifests (deployment, service)
• Startup.cs is .NET Core Web API startup & path routing config
• Program.cs is .NET Core Web API environment variable mapping config

Setting Up

To setup this project, you need to clone the git repo

$ git clone https://github.com/kubeopsskills/dotnet-core-web-api.git
$ cd dotnet-core-web-api

followed by

$ dotnet restore

Deploying a .NET Core Web API microservice on Kubernetes

Prerequisite:

• .NET Core Web API Docker Image

Preparing Config Map for .NET Core Web API microservice

$ kubectl apply -k configs/prod

To deploy the microservice on Kubernetes, run following command:

$ kubectl apply -f manifests

This will deploy it on Kubernetes with the centralized config.

Deploying a .NET Core Web API microservice on Azure Container Instance (ACI)

Prerequisite:

• ACI Context

To deploy the microservice on ACI, run following command:

$ docker compose -f aci-docker-compose.yaml up -d

Deploying a .NET Core Web API microservice on AWS App Runner using AWS Copilot

Prerequisite:

• AWS Copilot

To deploy the microservice on AWS, following these steps:

• Prepare AWS IAM roles and AWS ECR repository for the microservice

$ copilot init --app kubeops-demo

• Create the test environment on AWS

$ copilot env init --name test --app kubeops-demo

• Deploy the microservice on the test environment

$ copilot svc deploy --env test
