Deploying an ASP.NET Core 8 Web API involves various steps and considerations to ensure your application runs smoothly in different environments. This guide covers deployment strategies, configurations, and best practices for deploying your Web API to various platforms, including Azure, AWS, Docker, Linux, and IIS on Windows Server.
Deployment is the process of distributing your application to a server where it can be accessed by users. Proper deployment ensures your application is reliable, scalable, and secure.
Before deploying, ensure your application is production-ready.
2.1 Configure Your Project Update your project file (.csproj) to ensure it is set up correctly for deployment.

AWS offers several services for deploying ASP.NET Core applications, including Elastic Beanstalk and ECS.
4.1 Deploying to AWS Elastic Beanstalk Step-by-Step Guide:Key Configuration Settings:
aws ecr create-repository --repository-name your-api-project
$(aws ecr get-login --no-include-email --region us-west-2)
docker build -t your-api-project .
docker tag your-api-project:latest <aws_account_id>.dkr.ecr.us-west-2.amazonaws.com/your-api-project:latest
docker push <aws_account_id>.dkr.ecr.us-west-2.amazonaws.com/your-api-project:latest

Key Components:
Docker allows you to containerize your application and run it consistently across different environments.
5.1 Create a Dockerfile
FROM mcr.microsoft.com/dotnet/aspnet:8.0 AS base
WORKDIR /app
EXPOSE 80
FROM mcr.microsoft.com/dotnet/sdk:8.0 AS build
WORKDIR /src
COPY ["YourApiProject.csproj", "./"]
RUN dotnet restore "./YourApiProject.csproj"
COPY . .
WORKDIR "/src/."
RUN dotnet build "YourApiProject.csproj" -c Release -o /app/build
FROM build AS publish
RUN dotnet publish "YourApiProject.csproj" -c Release -o /app/publish
FROM base AS final
WORKDIR /app
COPY --from=publish /app/publish .
ENTRYPOINT ["dotnet", "YourApiProject.dll"]
docker build -t your-api-project .
docker run -d -p 8080:80 your-api-project
Key Components:
Deploying an ASP.NET Core application to a Linux server involves setting up the server, configuring the environment, and deploying the application.
6.1 Prepare the Linux Server Install .NET Core Runtime:Follow the official Microsoft documentation to install the .NET runtime on your Linux distribution.
Example for Ubuntu:
wget https://packages.microsoft.com/config/ubuntu/20.04/packages-microsoft-prod.deb -O packages-microsoft-prod.deb
sudo dpkg -i packages-microsoft-prod.deb
sudo apt-get update
sudo apt-get install -y aspnetcore-runtime-8.0
sudo apt-get install nginx
Create an Nginx configuration file for your application.
Example Nginx Configuration (/etc/nginx/sites-available/default):
server {
listen 80;
server_name yourdomain.com;
location / {
proxy_pass http://localhost:5000;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection keep-alive;
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
}
}
sudo systemctl start nginx
sudo systemctl enable nginx
dotnet publish -c Release -o ./publish
scp -r ./publish user@yourlinuxserver:/var/www/your-api-project
Create a systemd service file to manage your application.
Example Systemd Service (/etc/systemd/system/your-api-project.service):
[Unit]
Description=Your API Project
After=network.target
[Service]
WorkingDirectory=/var/www/your-api-project
ExecStart=/usr/bin/dotnet /var/www/your-api-project/YourApiProject.dll
Restart=always
RestartSec=10
SyslogIdentifier=your-api-project
User=www-data
Environment=ASPNETCORE_ENVIRONMENT=Production
[Install]
WantedBy=multi-user.target
sudo systemctl start your-api-project
sudo systemctl enable your-api-project
Key Components:
Deploying to IIS involves setting up the server, configuring IIS, and deploying the application.
7.1 Prepare the Windows Server Install IIS:Use the Server Manager to install the Web Server (IIS) role and include the ASP.NET Core Hosting Bundle.
Install the ASP.NET Core Hosting Bundle:Download and install the ASP.NET Core Hosting Bundle from the Microsoft website.
7.2 Configure IIS Create a New Site in IIS:
dotnet publish -c Release -o ./publish
Use a tool like FileZilla or Windows Explorer to copy the published files to the IIS server.
Configure Permissions:Ensure the application pool identity has read and execute permissions on the application folder.
Key Components:
using Microsoft.AspNetCore.Builder;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;
using YourApiProject.Services;
var builder = WebApplication.CreateBuilder(args);
// Add services to the container
builder.Services.AddControllers();
builder.Services.AddScoped<IProductsService, ProductsService>();
var app = builder.Build();
if (app.Environment.IsDevelopment())
{
app.UseSwagger();
app.UseSwaggerUI(options =>
{
options.SwaggerEndpoint("/swagger/v1/swagger.json", "My API V1");
options.RoutePrefix = string.Empty; // Serve the Swagger UI at the app's root
});
}
app.UseHttpsRedirection();
app.UseAuthorization();
