How do I deploy an ASP.NET Core API using Docker?

To deploy an ASP.NET Core API using Docker, you need to create a Dockerfile, build the image, and run the container.

What should I include in my Dockerfile?

Your Dockerfile should include the base image, copy your project files, restore dependencies, build the project, and specify the entry point.

Can you give me an example of a Dockerfile for an ASP.NET Core API?

Sure! Here's a simple example:

FROM mcr.microsoft.com/dotnet/aspnet:5.0 AS base
WORKDIR /app
EXPOSE 80

FROM mcr.microsoft.com/dotnet/sdk:5.0 AS build
WORKDIR /src
COPY [YourProject].csproj .
RUN dotnet restore
COPY . .
RUN dotnet build -c Release -o /app

FROM build AS publish
RUN dotnet publish -c Release -o /app

FROM base AS final
WORKDIR /app
COPY --from=publish /app .
ENTRYPOINT ["dotnet", "[YourProject].dll"]

How do I build and run the Docker container?

You can build the Docker image using docker build -t your-image-name . and run it with docker run -d -p 8080:80 your-image-name.
