Introduction

.NET .NET is the free, open-source, cross-platform framework for building modern apps and powerful cloud services. In this article, we are going to deploy a freshly created .NET app to Valyent.

​
Prerequisites

  • a UNIX-like system (see WSL if you are using Windows), in order to use the Valyent CLI
  • a Valyent account, with a registered payment method (you can sign up here)
  • .NET installed on your machine

​
Installing the CLI

curl -L https://cli.valyent.cloud/install.sh | sh

You can inspect the installation script here and the GitHub repository.

​
Authenticating

valyent auth login

​
Initializing the project

In the first place, we are going to set up a new .NET project.

Then, we can scaffold the .NET project :

dotnet new web --name <replace_it_by_your_application_name>

Please note that most .NET apps require at least 1Go of RAM.

Now, we can initialize the valyent.toml configuration file, that allows to link the local codebase, to a Valyent application :

valyent init

This command will ask you to select/create a project and an associated application.

​
Adding the Dockerfile

Let’s add a Dockerfile so that Valyent can build a Docker image for your application.

touch Dockerfile

We can fill it this way :

# Adjust DOTNET_OS_VERSION as desired
ARG DOTNET_OS_VERSION="-alpine"
ARG DOTNET_SDK_VERSION=8.0

FROM mcr.microsoft.com/dotnet/sdk:${DOTNET_SDK_VERSION}${DOTNET_OS_VERSION} AS build
WORKDIR /src

# copy everything
COPY . ./
# restore as distinct layers
RUN dotnet restore
# build and publish a release
RUN dotnet publish -c Release -o /app

# final stage/image
FROM mcr.microsoft.com/dotnet/aspnet:${DOTNET_SDK_VERSION}
ENV ASPNETCORE_URLS http://+:8080
ENV ASPNETCORE_ENVIRONMENT Production
EXPOSE 8080
WORKDIR /app
COPY --from=build /app .
ENTRYPOINT [ "dotnet", "<replace_it_by_your_application_name>.dll" ]

​
Deploy the project

To expose the application’s port, we need to set up the PORT environment variable :

valyent env set PORT=8080

Then, we can deploy the application :

valyent deploy

Once the deployment is finished, type :

valyent open

to see your .NET application in your browser.
