Deploy .NET apps
.NET support is in beta
If you encounter an issue, please contact the support.Clever Cloud allows you to deploy .NET web applications. This page will explain you how to set up your application to run it on our service.
You do not need to change a lot in your application, the requirements will help you to configure your apps with some mandatory files to add, and properties to setup.
.NET version
The version used on Clever Cloud is 3.1
, so you can deploy applications for the two current LTS versions as shown on this page. No support will be provided for end-of-life versions.
Create an application on Clever Cloud
via the web console
- Create a new app by clicking on the Add an Application button, in the sidebar.
- Select a brand new instance (or a repository from GitHub if your account is linked).
- Then select .NET in the platform list.
- Configure your scaling options.
- Enter your application’s name and description and click “Next”. You can also select the region you want (North America or Europe).
Refer to https://www.clever-cloud.com/doc/getting-started/ for more details on application creation via the console.
via the Clever Tools CLI
- Make sure you have clever-tools installed locally. Report to https://www.clever-cloud.com/doc/reference/clever-tools/getting_started/
- In your code folder, do
clever create --type <type> <app-name> --region <zone> --org <org>
wheretype
is the type of technology you rely on,app-name
the name you want for your application,zone
deloyment zone (par
for Paris andmtl
for Montreal), andorg
the organization ID the application will be created under.
Refer to https://www.clever-cloud.com/doc/reference/clever-tools/create/ for more details on application creation with Clever Tools.
Necessary information
Be sure that:
- You have pushed in
master branch
. - You listen on
port 8080
, by default each .NET application is created with theASPNETCORE_URLS="http://0.0.0.0:8080"
environment variable. - You have committed the different files of your project and the corresponding project file (
.csproj
,.fsproj
or.vbproj
). If the project file is not at the root of the repository, you can use the APP_FOLDER environment variable. See the list of environment variables here.
Requirements
Let’s take an example with the Microsoft TodoApi project.
During deployment, the TodoApi.csproj
file and the target framework netcoreapp3.1
are automatically detected. Then, the .NET project is published :
dotnet publish --framework netcoreapp3.1 --configuration Release
No additional configuration is required (unless multiple project files or target frameworks are present, see the documentation below).
Multiple project files in the repository
If multiple project files are present in your repository, you can specify the file to use (without the .*proj extension) with the
CC_DOTNET_PROJ
environment variable.
CC_DOTNET_PROJ=TodoApi2
Multiple binary targets
If your project file defines multiple targets, like :
<Project Sdk="Microsoft.NET.Sdk.Web">
<PropertyGroup>
<TargetFramework>netcoreapp3.0;netcoreapp3.1</TargetFramework>
</PropertyGroup>
...
You must specify the one you want to run, with the CC_DOTNET_TFM
environment variable. If CC_DOTNET_TFM
is
specified, then the executable produced by this target is used to start the
application.
CC_DOTNET_TFM=netcoreapp3.1
Dependencies
Make sure to list all your dependencies in your project file. For example:
...
<ItemGroup>
<PackageReference Include="EntityFramework" Version="6.4.0" />
<PackageReference Include="Microsoft.VisualStudio.Web.CodeGeneration.Design" Version="3.1.2" />
<PackageReference Include="Microsoft.EntityFrameworkCore.Tools" Version="3.1.3">
<IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
<PrivateAssets>all</PrivateAssets>
</PackageReference>
</ItemGroup>
</Project>
Compiled dependencies are cached by default to speed up deployments. You can
disable dependencies caching completely by removing the CC_CACHE_DEPENDENCIES
environment variable. If you want to rebuild your application from scratch,
you can select “rebuild and restart” from the console or launch clever restart --without-cache
from CLI
The configuration to publish for
Release
by default, you can use the CC_DOTNET_PROFILE
environment variable to change this configuration.
CC_DOTNET_PROFILE=Debug
Private dependencies
Support for private dependencies will be available soon.
Deploy on Clever Cloud
Application deployment on Clever Cloud is via Git. Follow these steps to deploy your application.
More configuration
Need more configuration? To run a script at the end of your deployment? To add your private SSH key to access private dependencies? Go check the Common configuration page.
You may want to have an advanced usage of your application, in which case we recommend you to read the Administrate documentation section.
If you can’t find something or have a specific need like using a non supported version of a particular software, please reach out to the support.
