Deploying ASP.NET Core Applications to CAE

Prerequisites

An environment has been created. For details, see Creating an Environment and Application Management.

Forking Sample Source Code

Use your account to log in to GitHub and fork the sample source code repository to your personal account.

Source code address: https://github.com/Azure-Samples/dotnetcore-docs-hello-world.

Parsing Dockerfile

Dockerfile file in the sample repository.

# Specify the basic image as mcr.microsoft.com/dotnet/sdk:7.0, which is used as the build environment of the ASP.NET Core project.
FROM mcr.microsoft.com/dotnet/sdk:7.0 AS build
# Specify the working directory.
WORKDIR /source

# Copy the source code from the build host to the basic image and specify the working directory and build command.
COPY . ./dotnetcore-docs-hello-world/
WORKDIR /source/dotnetcore-docs-hello-world
RUN dotnet publish -c release -o /app 

# Specify the new basic image as mcr.microsoft.com/dotnet/aspnet:7.0 and copy the build product generated in step 2 to the new basic image.
FROM mcr.microsoft.com/dotnet/aspnet:7.0
WORKDIR /app
COPY --from=build /app ./

# Set the environment variable PORT and declare that the container port is 80.
ENV PORT 80
EXPOSE 80

# Specify the container startup command.
ENTRYPOINT ["dotnet", "dotnetcoresample.dll"]
