Working with the NuGet registry

You can configure the dotnet command-line interface (CLI) to publish NuGet packages to Registro del paquete de GitHub and to use packages stored on Registro del paquete de GitHub as dependencies in a .NET project.

el Registro del paquete de GitHub se encuentra disponible con GitHub Free, GitHub Pro, GitHub Free para organizaciones, GitHub Team, Nube de GitHub Enterprise, GitHub Enterprise Server, y GitHub AE.

Nota: Este tipo de paquete podría no estar disponible para tu instancia, ya que los administradores de sitio pueden habilitar o inhabilitar cada tipo de paquete compatible. Para obtener más información, consulta la sección "Configurar el soporte de los paquetes para tu empresa".

Authenticating to Registro del paquete de GitHub

You need an access token to publish, install, and delete packages.

You can use a personal access token (PAT) to authenticate to Registro del paquete de GitHub or the GitHub Enterprise Server API. When you create a personal access token, you can assign the token different scopes depending on your needs. For more information about packages-related scopes for a PAT, see "About permissions for GitHub Packages."

To authenticate to a Registro del paquete de GitHub registry within a GitHub Actions workflow, you can use:

  • GITHUB_TOKEN to publish packages associated with the workflow repository.
  • a PAT to install packages associated with other private repositories (which GITHUB_TOKEN can't access).

Authenticating with GITHUB_TOKEN in GitHub Actions

Use the following command to authenticate to Registro del paquete de GitHub in a GitHub Actions workflow using the GITHUB_TOKEN instead of hardcoding a token in a nuget.config file in the repository:

dotnet nuget add source --username USERNAME --password ${{ secrets.GITHUB_TOKEN }} --store-password-in-clear-text --name github "https://nuget.HOSTNAME/OWNER/index.json"

Para obtener más información sobre el GITHUB_TOKEN que se utiliza en los flujos de trabajo de GitHub Actions, consulta la sección "Autenticarse en un flujo de trabajo".

Authenticating with a personal access token

Debes utilizar un token de acceso personal con los alcances adecuados para publicar e instalar paquetes en Registro del paquete de GitHub. Para obtener más información, consulta "Acerca de Registro del paquete de GitHub".

To authenticate to Registro del paquete de GitHub with the dotnet command-line interface (CLI), create a nuget.config file in your project directory specifying Registro del paquete de GitHub as a source under packageSources for the dotnet CLI client.

You must replace:

  • USERNAME with the name of your user account on GitHub.
  • TOKEN with your personal access token.
  • OWNER with the name of the user or organization account that owns the repository containing your project.
  • HOSTNAME with the host name for tu instancia de GitHub Enterprise Server.

If your instance has subdomain isolation enabled:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <packageSources>
        <clear />
        <add key="github" value="https://nuget.HOSTNAME/OWNER/index.json" />
    </packageSources>
    <packageSourceCredentials>
        <github>
            <add key="Username" value="USERNAME" />
            <add key="ClearTextPassword" value="TOKEN" />
        </github>
    </packageSourceCredentials>
</configuration>

If your instance has subdomain isolation disabled:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <packageSources>
        <clear />
        <add key="github" value="https://HOSTNAME/_registry/nuget/OWNER/index.json" />
    </packageSources>
    <packageSourceCredentials>
        <github>
            <add key="Username" value="USERNAME" />
            <add key="ClearTextPassword" value="TOKEN" />
        </github>
    </packageSourceCredentials>
</configuration>

Publishing a package

You can publish a package to Registro del paquete de GitHub by authenticating with a nuget.config file, or by using the --api-key command line option with your GitHub personal access token (PAT).

Publishing a package using a GitHub PAT as your API key

If you don't already have a PAT to use for your account on tu instancia de GitHub Enterprise Server, see "Creating a personal access token."

  1. Create a new project.

    dotnet new console --name OctocatApp
  2. Package the project.

    dotnet pack --configuration Release
  3. Publish the package using your PAT as the API key.

    dotnet nuget push "bin/Release/OctocatApp.1.0.0.nupkg"  --api-key YOUR_GITHUB_PAT --source "github"

Después de que publiques un paquete, puedes verlo en GitHub. Para obtener más información, consulta "Visualizar paquetes".

Publishing a package using a nuget.config file

When publishing, you need to use the same value for OWNER in your csproj file that you use in your nuget.config authentication file. Specify or increment the version number in your .csproj file, then use the dotnet pack command to create a .nuspec file for that version. For more information on creating your package, see "Create and publish a package" in the Microsoft documentation.

  1. Autentícate en Registro del paquete de GitHub. Para obtener más información, consulta "Autenticar a Registro del paquete de GitHub."

  2. Create a new project.

    dotnet new console --name OctocatApp
  3. Add your project's specific information to your project's file, which ends in .csproj. You must replace:

    • OWNER with the name of the user or organization account that owns the repository containing your project.
    • REPOSITORY with the name of the repository containing the package you want to publish.
    • 1.0.0 with the version number of the package.
    • HOSTNAME with the host name for tu instancia de GitHub Enterprise Server.
    <Project Sdk="Microsoft.NET.Sdk">
    
      <PropertyGroup>
        <OutputType>Exe</OutputType>
        <TargetFramework>netcoreapp3.0</TargetFramework>
        <PackageId>OctocatApp</PackageId>
        <Version>1.0.0</Version>
        <Authors>Octocat</Authors>
        <Company>GitHub</Company>
        <PackageDescription>This package adds an Octocat!</PackageDescription>
        <RepositoryUrl>https://HOSTNAME/OWNER/REPOSITORY</RepositoryUrl>
      </PropertyGroup>
    
    </Project>
    
  4. Package the project.

    dotnet pack --configuration Release
  5. Publish the package using the key you specified in the nuget.config file.

    dotnet nuget push "bin/Release/OctocatApp.1.0.0.nupkg" --source "github"

Después de que publiques un paquete, puedes verlo en GitHub. Para obtener más información, consulta "Visualizar paquetes".

Publishing multiple packages to the same repository

To publish multiple packages to the same repository, you can include the same GitHub repository URL in the RepositoryURL fields in all .csproj project files. GitHub matches the repository based on that field.

For example, the OctodogApp and OctocatApp projects will publish to the same repository:

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>netcoreapp3.0</TargetFramework>
    <PackageId>OctodogApp</PackageId>
    <Version>1.0.0</Version>
    <Authors>Octodog</Authors>
    <Company>GitHub</Company>
    <PackageDescription>This package adds an Octodog!</PackageDescription>
    <RepositoryUrl>https://HOSTNAME/octo-org/octo-cats-and-dogs</RepositoryUrl>
  </PropertyGroup>

</Project>
<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>netcoreapp3.0</TargetFramework>
    <PackageId>OctocatApp</PackageId>
    <Version>1.0.0</Version>
    <Authors>Octocat</Authors>
    <Company>GitHub</Company>
    <PackageDescription>This package adds an Octocat!</PackageDescription>
    <RepositoryUrl>https://HOSTNAME/octo-org/octo-cats-and-dogs</RepositoryUrl>
  </PropertyGroup>

</Project>

Installing a package

Using packages from GitHub in your project is similar to using packages from nuget.org. Add your package dependencies to your .csproj file, specifying the package name and version. For more information on using a .csproj file in your project, see "Working with NuGet packages" in the Microsoft documentation.

  1. Autentícate en Registro del paquete de GitHub. Para obtener más información, consulta "Autenticar a Registro del paquete de GitHub."

  2. To use a package, add ItemGroup and configure the PackageReference field in the .csproj project file, replacing the OctokittenApp package with your package dependency and 1.0.0 with the version you want to use:

    <Project Sdk="Microsoft.NET.Sdk">
    
      <PropertyGroup>
        <OutputType>Exe</OutputType>
        <TargetFramework>netcoreapp3.0</TargetFramework>
        <PackageId>OctocatApp</PackageId>
        <Version>1.0.0</Version>
        <Authors>Octocat</Authors>
        <Company>GitHub</Company>
        <PackageDescription>This package adds an Octocat!</PackageDescription>
        <RepositoryUrl>https://HOSTNAME/OWNER/REPOSITORY</RepositoryUrl>
      </PropertyGroup>
    
      <ItemGroup>
        <PackageReference Include="OctokittenApp" Version="12.0.2" />
      </ItemGroup>
    
    </Project>
    
  3. Install the packages with the restore command.

    dotnet restore

Troubleshooting

Your NuGet package may fail to push if the RepositoryUrl in .csproj is not set to the expected repository .
