Deploy .NET apps
Overview
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 support is in beta
If you encounter an issue, please contact the support.Create an application on Clever Cloud
With the web console
Refer to our getting started for more details on application creation via the console.
With the Clever Tools CLI
- Make sure you have clever-tools installed locally or follow our CLI getting started guide.
- In your code folder, do
clever create --type <type> <app-name> --region <zone> --org <org>
where :type
is the type of technology you rely onapp-name
the name you want for your application,zone
deployment zone (par
for Paris andmtl
for Montreal)org
the organization ID the application will be created under.
Refer to clever create for more details on application creation with Clever Tools.
Setting up environment variables on Clever Cloud
With the Clever Cloud console
- Go to the Clever Cloud console, and find the app you want to fine tune under it’s organization.
- Find the Environment variables menu and select it.
- In this menu, you will see a form with VARIABLE_NAME and variable value fields.
- Fill them with the desired values then select Add.
- Don’t forget to “Update Changes” at the end of the menu.
With the Clever Tools CLI
- Make sure you have clever-tools installed locally. Refer to our CLI getting started.
- In your code folder, do
clever env set <variable-name> <variable-value>
Refer to environment variables reference for more details on available environment variables on Clever Cloud.
You can of course create custom ones with the interface we just demonstrated, they will be available for your application.
Configure your Dotnet application
.NET version
The default version used on Clever Cloud is 6.0
. You can change it to 5.0
by setting the CC_DOTNET_VERSION
environment variable to 5.0
. No support will be provided for end-of-life versions.
Requirements
Be sure that:
- You have pushed in master branch.
- You listen on port 8080, by default each .NET application is created with the
ASPNETCORE_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
).
Let’s take an example with the simple-feed-reader project.
First, you need to add the APP_FOLDER=SimpleFeedReader
environment variable to define the application folder inside the Git repository.
During deployment, the SimpleFeedReader.csproj
file and the target framework net5.0
are automatically detected. Then, the .NET project is published:
dotnet publish --framework net5.0 --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=SimpleFeedReader
Multiple binary targets
If your project file defines multiple targets, like :
<Project Sdk="Microsoft.NET.Sdk.Web">
<PropertyGroup>
<TargetFramework>net5.0;net6.0</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=net5.0
Dependencies
Make sure to list all your dependencies in your project file. For example:
...
<ItemGroup>
<PackageReference Include="AutoMapper.Extensions.Microsoft.DependencyInjection" Version="5.0.1" />
<PackageReference Include="Microsoft.SyndicationFeed.ReaderWriter" Version="1.0.2" />
</ItemGroup>
</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
Configure profile
The default profile is Release
but you can use the CC_DOTNET_PROFILE
environment variable to change this configuration.
CC_DOTNET_PROFILE=Debug
Custom run command
If you need to run a custom command (or just pass options to the program), you can specify it through the CC_RUN_COMMAND
environment variable.
For instance, you can have CC_RUN_COMMAND=./bin/Release/net5.0/myapp <options>
.
Private dependencies
Support for private dependencies will be available soon.
Environment injection
Clever Cloud injects environment variables from your application settings as mentioned in setting up environment variables and is also injecting in your application production environment, those from your linked add-ons.
To access environment variables from your code, you can use System.Environment.GetEnvironmentVariable("MY_VARIABLE")"
.
Git Deployment on Clever Cloud
You need Git on your computer to deploy via this tool. Here is the official website of Git to get more information: git-scm.com
Setting up your remotes
The “Information” page of your app gives you your Git deployment URL, it looks like this:
git+ssh://[email protected]/<your_app_id>.git
- Copy it in your clipboard
Locally, under your code folder, type in
git init
to set up a new git repository or skip this step if you already have oneAdd the deploy URL with
git remote add <name> <your-git-deployment-url>
Add your files via
git add <files path>
and commit them viagit commit -m <your commit message>
Now push your application on Clever Cloud with
git push <name> master
Refer to git deployments for more details.
Linking a database or any other add-on to your application
By linking an application to an add-on, the application has the add-on environment variables in its own environment by default.
On add-on creation
Many add-ons do exist on Clever Cloud, please refer to the full list and check add-ons dedicated pages for full instructions.
During add-on creation, you will see Applications screen, with a list of your applications. You can toggle the button to Link and click next. If you finish the process of add-on creation, the application will automatically be linked to it.
Add-on already exists
In the Clever Cloud console, under the Service Dependencies menu of your application, you can use the Link addons dropdown menu to select the name of the add-on you want to link and use the add button to finish the process.
You can also link another application from the same page in the Clever Cloud console, using the Link applications dropdown menu.
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.
