I'm running docker-compose up --force-recreate --build and obtaining the following error:

I've included the necessary credentials in NuGet.config at %appdata%/roaming/nuget and the corresponding  package sources with the following feed url https://nuget.telerik.com/v3/index.json:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <packageSources>
    <add key="Microsoft Visual Studio Offline Packages" value="C:\Program Files (x86)\Microsoft SDKs\NuGetPackages\" />
    <add key="nuget.org" value="https://api.nuget.org/v3/index.json" />
    <add key="Telerik" value="https://nuget.telerik.com/nuget" />
  </packageSources>
    <packageSourceCredentials>
    <Telerik>
        <add key="Username" value="******@******.pt" />
        <add key="ClearTextPassword" value="**********" />
    </Telerik>
  </packageSourceCredentials>

    <add key="disabled" value="False" />
  </packageManagement>
  <disabledPackageSources>
    <add key="pbanuget" value="true" />
  </disabledPackageSources>
</configuration>

The following is the .csproj file.

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

  <PropertyGroup>
    <TargetFramework>net7.0</TargetFramework>
    <Nullable>enable</Nullable>
    <ImplicitUsings>enable</ImplicitUsings>
    <RootNamespace>monitorix-ui</RootNamespace>
    <UserSecretsId>532751be-63e3-425b-807f-72d212ce24ca</UserSecretsId>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="BlazorMonaco" Version="3.0.0" />
    <PackageReference Include="Telerik.UI.for.Blazor" Version="4.0.1" />
  </ItemGroup>

</Project>

And finally my dockerfile:

FROM mcr.microsoft.com/dotnet/sdk:7.0
# Needed to install the web-ui dependencies
WORKDIR /app
RUN apt install -y curl
RUN curl -sL https://deb.nodesource.com/setup_14.x | bash -
RUN apt-get install -y nodejs
RUN curl -L https://www.npmjs.com/install.sh | sh

# SSH tools
RUN apt install -y sshpass

# Copy app
WORKDIR /app
COPY . . 

# Install web-ui dependencies
WORKDIR /app/wwwroot
RUN npm install


# dotnet core app restore/build and launch
WORKDIR /app
RUN dotnet publish -r ubuntu.18.04-x64 -c Release -o ./deploy/release

EXPOSE 80
ENTRYPOINT ["./app/deploy/monitorix-ui"]

What seems to be the problem here? Thank you

Hello Ricardo,

This error...

>> No packages exist with this id in source(s): nuget.org

...means that your NuGet.Config file is not used - notice that the "Telerik" feed is not mentioned at all in the error message. The most common reason is that the file is not copied together with the project.

Regards,
Dimo
