Getting no such file or directory when publishing self-contained app as container

[paulomorgado]

With these properties in my csproj are:

  <PropertyGroup>
    <DockerDefaultTargetOS>Linux</DockerDefaultTargetOS>
    <ContainerRuntimeIdentifier>linux-x64</ContainerRuntimeIdentifier>
    <DockerfileContext>..\..</DockerfileContext>
    <ContainerRepository>MyApp</ContainerRepository>
    <ContainerImageTag>$(Version)</ContainerImageTag>
    <UseApphost>true</UseApphost>-->
    <EnableTrimAnalyzer>True</EnableTrimAnalyzer>
    <EnableSdkContainerDebugging Condition="'$(Configuration)' == 'Debug'">True</EnableSdkContainerDebugging>
    <!-- this saves the image to the artifacts directory, so it can be published as an artifact and does not register the image in the local docker registry -->
    <ContainerArchiveOutputPath Condition="'$(ContainerArchiveOutputBasePath)' != ''">$(ContainerArchiveOutputBasePath)$(MSBuildProjectName)-$(Version).tar</ContainerArchiveOutputPath>
  </PropertyGroup>

  <ItemGroup>
    <ContainerEnvironmentVariable Include="ASPNETCORE_HTTP_PORTS" Value="8080" />
    <ContainerEnvironmentVariable Remove="ASPNETCORE_HTTPs_PORTS" />
  </ItemGroup>

And this command line to build the image:

dotnet publish `
    -target:PublishContainer `
    "-binaryLogger:$($local:baseOutputPath)_build-container-image.binlog" `
    --property "ContainerArchiveOutputBasePath=$($local:artifactsPath)" `
    --property DebugType=None `
    --property DebugSymbols=false `
    --property CopyDebugSymbolFilesFromPackages=false `
    --property CopyOutputSymbolsToPublishDirectory=false `
    --self-contained `
    "$($PWD)/src/MyApp/MyApp.csproj"

I'm getting this, when I run the container,:

$ docker run --rm MyApp:0.1.0-preview.1
exec /app/MyApp.exe: no such file or directory

If try to start it explicitly from inside the container, I get this:

$ docker run --rm --entrypoint /bin/bash MyApp:0.1.0-preview.1
app@f237c36ce693:/app$ /app/MyApp.exe
bash: /app/MyApp.exe: cannot execute: required file not found

The same set of files runs fine from WSL, but I have .NET 8.0 on my WSL installation.

A simple project also runs fine self-contained.

How can I find what's missing?

Got some help and it turns out that it was just replacing

<ContainerRuntimeIdentifier>linux-x64</ContainerRuntimeIdentifier>

with

<RuntimeIdentifier>linux-x64</RuntimeIdentifier>
